Case Fans for cooling your computer
Graphic cards are now often larger with built-in memory modules and running more functions quicker to keep this in working order many cards now come with a cooling fan fitted to keep the chips cool and operating.
Cooling a PC can work in a very similar way, the main purpose is to ensure that for the processor the compulsory heat sink and fan is rated correctly. This means that it can produce enough airflow onto the heat sink to cool the processor. The circulating airflow moves the warm air away from the processor and is often trapped within the PC Case.
Air Cooling
Depending on how many devices you have to cool you can either install a small number of powerful fans that are likely to be louder or several weaker fans that are much quieter. Fans come in various sizes to fit all situations, air cooling is all about passing air over the component which will move the warm air away and into the case.
3-4 Fan Standard Set-ups
The standard for most computers now in addition to the CPU fan is it will have one or two exhaust fans which will force warm air from the inside of the case to the outside. Often one or two fans are now built into the Power Supply. (PSU) Not only does this keep the PSU cool but it draws air from the inside through the PSU and out acting as an exhaust fan.
Also an additional fan is mounted at the front of the case to bring cooler air in so that it can be circulated and mix with the warmer air before being drawn out via the exhaust fans.
With 3 or 4 fans installed your system should remain very quiet, the CPU fan you can not do much about and you should just lave it to keep one of the main parts cool and working. For exhaust fans to either bring in or expel air you could either go for the standard options or look at variable speed fans which allows you to lower speed, as a result the noise will reduce and be quieter.
Prices for fans start from just a couple of £ and can increase to the £40-50 range depending on the size and specification.
