I recently bought a Zalman CNPS9900ALED for my Core i7 920. As soon as I plugged it in, it was on its loudest setting. With the stock i7 cooler it was always quiet, until I went into a game then it would speed up. So I tried enabling the thermal control in the BIOS (Have no idea why the stock cooler worked as if it was on but I am positive it was turned off.) and the fan turned completely off. So I booted into Windows 7 x64 and ran Prime95 while the fan was still turned off. I was watching the temperatures with Easytune 6 for my Gigabyte motherboard. (Awful software, can you recommend anything better?) The fan turned on when the CPU hit 60 C....no way to change this.
Since the fan was either on its loudest setting, or off, could I have a faulty heatsink?
