I found and added a 5th fan to the front of my computer - a 120mm fan, the last fan my system can have, to help keep it cool. It does increase the noise level a bit, but not significantly. The motherboard temperature is already about 10C lower, and it's helped the circulation for the CPU heatsink fan lowering it about 5C. It'll help too when I upgrade my video card, as the newer cards create a lot of heat. - Steve
