Of Heat sinks and Temperature
19 April 2009
Cooling fans cannot work alone, for before they can blow away the heat produced by the microprocessor, it has to be dissipated and in that game, area is the key. Ever wonder why the heat sink of your processor has fins, area, it increases the surface area at which the cold air can be blown off from thus efficiently cooling your system. The more fins, the more area the heat has to dissipate out of and the better for the fan. Other more expensive after-market cooling systems use heat pipes(pure copper tubes filled with gasses that helps draw heat away from critical parts), exotic heat transfer materials and powerful fans to effectively cool the computer system.
The power supply unit comes with a built-in fan and so does the processor or even the video display card. For most applications, these would provide ample cooling but if you love to leave the computer on for long periods, additional cooling may be needed to keep the system from toasting in it’s own juice. Newer designs of motherboards and processors have less heat production which is actually wasted energy. An additional fan or two may be necessary to maintain proper health of your computer system, one blowing in and one sucking out or both sucking out (everybody has their own opinion on this so you decide).
