Cooling is essential for optimal computing but installing a custom air conditioning unit for your motherboard is well, kinda’ going overboard. Cooling fans tend to work best and with many aftermarket brands and types around, they are essential for keeping your computer cool.
Choosing the best would be a good investment but you should also remember to keep things clean. Dust on components tends to heat things up a bit causing components to prematurely fail. Simple dusting of all the CPU or the box that contains everything else asides from the mouse keyboard and monitor is essential. It maximizes the performance of the fans to keep the components cool especially if you tend to overclock for gaming applications. You might want to get a high end cooler for your video card too just for good measure.
