I can't get my CPU fan quiet...
I have a 990FXA-UD3 motherboard with an older AMD Athlon II X4 640 quad-core CPU at stock 3.0 GHz, using stock fan on the CPU FAN header. Nothing exotic, obviously. Problem is, I cannot keep the fan speeds down low enough for normal use. Using the BIOS's "normal" setting, it just runs full blast and is the loudest CPU fan I've ever heard. Just migraine-inducing. Changing the setting to "silent" helps significantly when the computer is doing essentially nothing, but any little bit of CPU power draw revs the fan up loud, then back down. It amounts to every new tab you open in Firefox causing a WHIIRRRRRrrrrr sound. Not acceptable.
Loading Easy Tune 6 doesn't help much. Even going to the Smart tab, and dramatically reducing the fan speed points on the graph barely changes things. I set it all the way down to 10% (the lowest allowed) for anything up to 50 degrees C, then up to 100% at 62. This seems to help SLIGHTLY compared to just using "silent" in BIOS. The CPU fan speed in ET6 shows around 2700 RPM for what I consider a reasonable fan noise, and occasionally will drop below that for a very nice, quiet computer. However, virtually any activity ramps it up like crazy, even though the CPU temp is nowhere near 50 C! So clearly ET6 sucks.
On top of all this, ET6 loves to crash for no reason, leaving the CPU fan to fluctuate wildly again.
What gives??? All I want, like most folks, is for the CPU fan to be as quiet as possible until I ask it to do something significant, like encode video, at which point it can go nuts. Am I doing something wrong?
