Functions Of A CPU Cooling Fan

Monday 6 July 2009 @ 2:07 pm

by Ranju Kumar
While operating a Computer we often notice heat getting generated from various parts of the computer. To cool down the machine and to ward off the heat computer fans are used. CPU cooling fans are one of the main cooling agents in the computer. If the heat generated is not dispersed immediately it can cause severe damage to other computer components. Though computers are designed in a fashion that generation of heat can be kept under control but a special cooling agent is always advisable.

The main functions of a CPU cooling fans are that it flushes out the heat and draws cool air in the system. Cooling fans are also fitted in hard drives and mother boards. There are about three to four fans fixed in the central processing unit. Computers built in olden were not equipped for any kind of ventilation only a aluminum sink along with couple of fans were attached. But this was not enough with magnitude one uses computer today. Computers today are used for more than 12 to 15 hours a day hence only an aluminum sink will not be sufficient for ventilation. Cooling fans were introduced and proved to be very economical and efficient for using the PC for long duration.

The main function of a CPU fans is to keep the Central Processing Unit cool. However there can be some obstruction in smooth functioning of the CPU cooling fan like Dust. Dust settles down on the blades of these fans reducing their functioning capabilities. Hence regular maintenance is required to keep the CPU cooling fans in good working condition. Heat Transfers or Poor flow of heat can also be an obstruction in reducing its efficiency.

Many of them do not realize the importance of Computer Cooling system. Lack of knowledge and ignorance about its components can be one of the important factors. Hence it is important as a computer literate to know the various peripherals of the machine and their functions. This not only helps in maintaining them but also avoiding any damage to the component. There are chances that you might lose an important component due to overheating and which may cost you very dearly for replacing it with a new one.

Operating Laptops also generates very high amount of heat, though all the laptops are also well equipped with a proper cooling system. Overheating can cause severe damage to the laptop and some time even stop functioning completely. Hence all the Laptops are attached with laptop coolers which do the same function as the CPU cooling fan.

There are various types of fans available in the market, you can select one depending on the magnitude of work you will be doing on your machine. You can either consult a professional or do some researches before you go for one. You can check on the internet for some tips which can come very handy while buying a suitable fan for your system. Different varieties of fans are available for different systems, you just need to know which one to go for.

What Do UPS Power Systems Do

Thursday 2 July 2009 @ 11:07 pm

by David Sprake
UPS power systems are not, as some might suspect, the power systems used by UPS shipping, but rather, UPS stands for Uninterruptible Power Supply. The term itself is actually somewhat broad. A UPS system might be an entire system of backup generators for use in hospitals to ensure that delicate operations are not made volatile by a sudden power outage, or they might be a single battery used in a computer processor to make sure you do not lose an hour of work when a fuse blows.

In any event, a UPS power system is there simply to keep your power supply uninterrupted. Its basically a wise investment. You can either spend a little extra to protect yourself against the unpredictability of your primary external supply of power, ie your electrical outlets and what have you, or you can wait until a power surge fries your computer and you have to buy a new one, or lose a days worth of progress on a company project when everyones workstations go out at the same time.

Think of a UPS power system as insurance against power failure, or taking an umbrella with you when it gets a little overcast, its better to have it and not need it than need it and not have it.

There are a number of discrepancies in power that the UPS are capable of modifying or amending. These include a normal power failure, voltage sag, over voltage, under voltage, voltage spike, voltage sag, frequency variation, harmonic distortion, line noise and switching transient. According to these various problems, uninterrupted power supplies are grouped into different categories so that consumers are able to buy them as per their requirement.

For home computer users, you will want either an RBC battery or a power protection device. These will basically ensure that, should something go wrong with your external power, you have, at least, several minutes to save what you were doing and shut your computer down safely, which is quite a bit nicer than losing power suddenly and worrying about whether or not your computers hardware has been permanently destroyed by a power surge.

For anyone running a network or client service, you are probably going to want to look into Riello UPS. Riello UPS is considered one of the leaders in the field of providing reliable standby power, and their Netman series of network protectors are, to be frank, some of the best in the world when it comes to resilience and reliability.

Basically, if you run any sort of network communications, look into Riello UPS. Be it at an office or just running a hotspot at a coffee shop, losing your network can be pretty much the same thing as losing work progress, losing customers, and losing money.

Situations When Nothing But A Rugged Portable Computer System Will Do

Thursday 2 July 2009 @ 11:07 pm

by Art Gib
There are practically infinite numbers of situations where computer communication is vital but where common computer equipment will be woefully inadequate or fail altogether. These situations may be in governmental, civil, or emergency contexts and call for rugged portable computer systems that can take huge amounts of physical stress yet still perform at peak efficiency. Here are some essential features to look for when choosing such a system, the applications for which they are appropriate, and situations when nothing but a rugged system will do.

Emergencies

In times of emergency, equipment failure is simply not an option. Computer units need to be both vehicle-mounted and ground portable in order to get the job done in a variety of contexts. A good supplier of rugged systems will carry computer systems that already come with interactive mapping systems, GPS, and other software that will automatically report locations of incidents so that responders can arrive as soon as possible.

Vehicle-mounted computer systems are convenient and easily-accessed tools that can be used in airplanes and helicopters as well as in cars and on boats and still work great no matter the temperature or weather conditions.

Government and Law Enforcement

Law enforcement officers face difficult situations on a daily basis that require computer equipment that can “take it.” Bicycle police, mounted police, and SWAT teams all need hand-held systems that are strong and can withstand the abuses inflicted upon them by their owners. Kneeboard tablet PCs are a great choice for these occupations, and there are even hand held speech to speech translating systems on the market that are useful when language barriers are a problem.

Rugged systems are essential in military contexts where they are essential to maintaining communications between troops in war zones and in other areas as well. Products may also include situational awareness equipment and command and control systems that help soldiers stay in control and carry out their missions.

Civilian Applications

There are many civilian organizations who take on humanitarian causes under the most extreme physical circumstances. While a common laptop would wilt under such conditions, a rugged system will be able to take the abuses heaped upon it and keep running at peak efficiency. Many rugged systems come sealed so that they can be used underwater, in hot deserts, and even in subzero arctic situations, making them ideal tools for scientists and explorers.

Computer systems are not just for the home or office anymore: they have become indispensable machines in just about every walk of life and situation imaginable. Rugged systems are designed to provide reliable computer services under the most extreme circumstances.

Keeping Your Uninterruptible Power Supply Uninterruptible

Sunday 28 June 2009 @ 9:06 am

by David Sprake
Batteries need to be replaced from time to time and devices need to be tested. Here are a few simple tips to keep your uninterruptible power supply uninterrupted.

So you have got your workstations or your network plugged into an uninterruptible power supply. Well, you have made the right decision. No more worry about losing hours of progress thanks to a blown fuse. However, there is a degree of maintenance that goes into keeping uninterruptible power supplies uninterrupted.

For example, say you use RBC batteries in your workstation. That is a great idea, but an even better idea would be to replace that battery before it gets too old.

RBC batteries last a remarkably long time, but they do eventually wear out. Most RBC battery suppliers offer a one year warranty, so its not a bad idea to replace the battery once the warranty runs out. We know, we know, nobody wants an annual expense stacked on top of the bills they are already paying, but if you look at it as an investment, it makes sense. You can either spend a few pounds each year to replace your RBC, or you can risk your battery burning out and leaving your computer unprotected in the event of a power outage.

Another example would be if you maintain any sort of communications network, be it an office network or a wireless internet hotspot. Obviously, you want to keep your network up and running, or else risk losing work progress or customers, so you get an uninterruptible power supply system to keep your network going should there be a power surge or what have you.

Great, but try to make sure you are relying on a reliable product to provide you with that security. Going with a top Brand might cost a pound or two more than some no-name brand backup power supply product, but you wont get the same kind of reliability, you are not likely to get any sort of warranty, and if the thing breaks down the first time you need it, you are likely to eat the costs yourself.

An on-line UPS is perfect for situations where there are extreme voltage fluctuations and the equipment connected to it is highly sensitive. They are more expensive than the line-interactive and the stand by UPS and were earlier available only for larger consumption installations. However, they are now available in smaller consumer equipment that use about 500watts of power. They are convenient for locations where there are large numbers of noise-making equipments such as those seen in large industries. Apart from this they may require a back up generator to supply an uninterrupted power supply to these equipments.

Really it comes down to the same kind of common sense you would practice in maintaining any electronic device. When your UPS is all hooked up, set up an old laptop or something and run a test now and then to make sure it will be able to provide standby power when the lights go out. Replace it when it starts getting old. Simply put, you want to make sure its going to work when you need it to work.

Why Would You Need An Uninterruptible Power Supply (UPS)

Sunday 28 June 2009 @ 8:06 am

by David Sprake
Deciding on a good Uninterruptible Power Supply is a difficult situation as there are so many choices out there in the market.The Uninterruptible Power Supply uses Eco Energy level ratings that conform to the European Commission Code of Conduct and offers the utmost levels of environment protection that a UPS can manage to provide. There are six different levels with the sixth one being the greatest that an on-line uninterruptible power supply can provide. These excessive levels of eco protection show that Riello brand systems promote cost efficiency, low consumption, less amount of heat generation and reduced carbon footprints.

A commendable effort made by leading brands is to provide apart from high quality, efficient uninterruptible power supplies systems that are ecology friendly. It focuses on providing battery solutions that can help prolong the battery life and cut down the frequency of battery replacements and removal programmes. It strives to decrease the effect on upstream devices and provide a wider storage capacity. The uninterruptible power supply is designed to operate in a fashion that corresponds to the electrical aspects of the utility power to the energy saving execution needed by the workload.

Uninterruptible power supplies, though useful for many electrical devices, are mainly used for computers, which in todays world are the life blood of our society because they are required practically everywhere starting from home, hospitals, banks, schools, universities, airports and every business organisation that exists on earth. However, these equipments are vulnerable if they do not have a back up source of energy to keep them running in case of a power cut. Therefore, to have an uninterrupted power supply, you must have a UPS, to support your precious computer.

Lightning can badly affect your hardware, as it is capable of transmitting through telecommunication cables and causing short circuits as it passes through. To avoid such a situation it is necessary to put in a UPS data protection circuit separating your computer network from the telecommunications data line. This will prevent the power surge from destructing other devices and saving you the cost of replacing the entire burnt out plugs and switches. You will only need to replace the data protection device that gets destroyed when such an electrical surge takes place.

As a UPS provides backup power to a few of the most important data centres, it is highly essential that energy conservation solutions be worked out in order to have an uninterrupted power supply. Costs must be brought down while keeping the competency levels high and maintain the ability to resist a utility power cut or a sudden interruption of regular supply. The aim should be to preserve the maximum levels of efficiency while maintaining a lesser burden on these UPS power supplies and at the same time providing the ultimate protection to the end source, your sensitive devices.

By using this environment friendly technology a UPS has not only proved that it is concerned about the biosphere but has also become one of the only producers of uninterruptible power supply systems that uses this unique technique. Its strong commitment towards the environment plus its high standards of quality makes any good brand of uninterruptible power supply an ideal choice for our power backup solutions.

How To Get The Best APC Replacement Battery

Tuesday 23 June 2009 @ 10:06 am

by David Sprake
Below are some tips on finding the best APC replacement battery for your money, as well as some advice on making sure you are getting the battery you need.

If you go to an APC replacement battery suppliers website, one of the first things you will notice when you place an order is a big bolded warning asking that you make sure to check the size and specifications of your battery before finishing your order.

This is because hardware manufacturers have a tendency to switch specifications at the drop of a hat and without notice, so one of the primary customer complaints these suppliers receive is that the battery they just spent fifty pounds on wont fit in their processor. So the first step to finding the best APC replacement battery is to check your specs and make sure you are getting the right battery in the first place.

Secondly, there are a number of APC battery manufacturers out there, and not all of them are all that great. You might think you are saving some money by going with some generic cheapo brand RBC battery maker, but in the long run, you are running a higher risk of that battery not being there for you when you need it and shorting out right when a fuse blows.

Were not saying to buy the most expensive replacement battery you can find, but remember that cheapo batteries are cheap because they are cheaply made, and cheaply made products have a higher frequency of unreliability than the brands considered to be the best in the market. You can go ahead and use the save-a-lot brand double A batteries when your Gameboy dies, but when it comes to securing a workstation, there is a lot more at risk than beating your high score at Tetris. Companies like Yuasa and CSB are generally considered to be amongst the best in the market of APC batteries.

If you do not like going on brand-name alone, you can go ahead and look online for customer testimonials. Google up some unbiased third party websites that can fill you on exactly how reliable this or that battery is.

In any event, it comes down to this, know what you need, shop around, and do not try to cheap out. Think of your APC replacement battery as an insurance policy against power malfunctions, in that its an investment that, in the end, might save you hundreds in computer repairs or lost work.

How Does Device Driver Development Help Computer Instability?

Saturday 20 June 2009 @ 11:06 pm

by Jordan McPelt
Computers are one complicated machine that you can have. Aside from the operating system in order to control the running applications in your computer, you also need to have device drivers in order for your hardware to work properly as well.

Device drivers act as the bridge between your computer and your hardware. Have you noticed that when you buy a new hardware, Bluetooth device for example, will not work after plugging it in to your computer? This is for the reason that the computer still does not have the drivers needed for it to be controlled by the computer. You need to install the proper drivers in order to make work or to be recognized by the system.

There are times when these drivers are not properly written by their manufacturers. These drivers are making your system unstable, leading your computer to crash in the process. This is the reason why device driver development has been done.

Device driver development is used to keep your system from crashing due to unwritten drivers. The device driver development will be producing drivers that would let you maximize the quality of how your hardware functions. This will also include some driver updates that are suggested to be used in order to keep your system in line with the latest changes in the hardware. You might notice that there are some hardware problems that are resolved by just updating it.

If you will notice, this has been very widely explored that there has been several versions of hardware drivers. There are drivers that would work in regular computers while there are others that are going to function to MACs only. Aside from the types of computers, the operating system is also taken into consideration. There has been some device driver development done in order to fit the latest Windows Vista operating system while others are just suited for Windows XP. Even if the operating systems are both manufactured by windows, they still have different components that will make a hardware and its driver incompatible with it.

So we see how the development of drivers have changed during time. With the technology building up, all hardware manufacturers are doing their best in order to sign their drivers properly to avoid any instability. Also if it is possible, choose only the best and the most reliable hardware so you will be sure that you are updated and thus promote the highest functionality of your hardware.

Power Protection And How To Plan For It

Saturday 20 June 2009 @ 11:06 pm

by David Sprake
The first thing that you must do is to plan out an appropriate solution for your kind of UPS system requirement. For this you need to work out your present usage and the expected power utilisation in the coming years. This includes all kinds of equipment that will ultimately use the UPS and chalk out the ones that are very essential and cannot be done without. Evaluating the future consumption is also important because you will certainly be looking to an expansion, which will mean an increase in the number of equipments and more power load. Therefore a powerful power protection solution will be required to meet the energy consumption.

There are various power solutions for different kinds of applications and the energy usage. If it is a power protection solution for crucial equipments that you are in search of, then the redundant power supplies are the best resort. These run using two conjoined UPS systems to provide uninterrupted power supply to your sensitive equipments.

If you are looking for a power protection system that can provide an extended support to your normal UPS system, using a back up generator would be an ideal solution. As an UPS has the capacity to provide energy for only a short period of time, you will require a backup source that will allow your equipments to work longer or until the main utility supply is restored.

Apart from getting an UPS system and a backup generator, there are other things that need to be seen to. It is essential to have an UPS that has a self-monitoring, self-evaluating management capacity that can analyse the voltage output, thereby preventing the UPS from suddenly collapsing without notice. It should also be noted that your equipments are compatible with such a power solution.

Also it is necessary to work out if a single large UPS is a more convenient option as compared to several smaller UPS connected to various equipments. This will also be determined by the number of equipments that are run more frequently and the ones that are seldom used.

Power distribution is also an important factor to be considered because every equipment has a different requirement. The power distribution system helps distribute energy according to the system requirement thereby maintaining a proper balance and an efficient service.

The last and the most important fact that must be considered while purchasing a UPS and a power distribution system is the warranty that goes with it. Usually a warranty on these systems lasts for about two years relying on its capacity and the manufacturer. You must also ascertain apart from the warranty period, the provision for repair and maintenance by the manufacturer.

Keeping these points in mind, you will be able to work out a proper power solution for your company or for your individual use.
