When I bought my PC; I thought this time - this time I will get a silent pc. So I bought a silent cabinet (expensive). I bought a silent video card (expensive). Bought a silent chassis fan. Bought an Asrock x58 Supercomputer motherboard + core i7-920 with box cooler. Now the issue is that it goes up to 65 degrees very quickly. Even if it is doing small things such as displaying a 720p movie. And when it hits 65 degrees, the cpu cooler comes on very loudly. When it goes below 65 degrees again, Asrock has supplied a tool (ASRockOC) that will let me press a button, and the fan noise goes away. So up to 65 degrees its fine. After that is makes noise until I get it below 65 again and press the button. My question is, can I raise this limit of 65 degrees some how, so that the fan doesn't come on until 70-75 degrees? Or is there anything else I can do?
