Is your BIOS configured to vary the CPU fan speed as CPU temps change or is it always running at 12V. For this to work it needs to be plugged into the CPU fan header and not some other header on the mobo. If you're using another header or plugging it into on of the PSU's molex connectors, it's probably running full-speed all the time.
If it's plugged into the correct header and it's running at high speed because your CPU is hot, you might be stuck.
