In your BIOS settings you can adjust the fan speed based on chipset temperatures. Looking at your reported RPM's your fan is running at about 1/2 speed. The VC-RE has a maximum RPM of approximately 5,000 RPM's.
I'm surprised your's is noisy at 1/2 speed. You might have got a lemon.
I havenâ€™t been into the BIOS since I built this rig in the spring of 2006. Here is a screen shot I took then. Ignore the fan speed you see in the screen shot. Have people gotten Evercool lemons?
whats the chipset on 100% temp in bios? if its fully on all the time then that could be your issue. Another way you could tell is looking at the evercool, is it lit up brightly? If so then its running a decent speed. I set mine for 45C max just to help keep my vid card cooler(running my case fans low makes 36C idle on the chipset). But If I set it to 50C max which is very acceptable then there is no lights on the evercool and its silent. With my case fans turned up and 45C max on the chipset it still has no lights on and runs 32C.
See my screen shot above. I havenâ€™t changed a thing since I took the screen shot. Doesnâ€™t look like itâ€™s set to stay on all the time, but itâ€™s been so long since Iâ€™ve looked at that stuff, Iâ€™ve forgot half of what I learned when I built this rig.
I just opened the case, as I hadnâ€™t even looked in there after I booted it back up yesterday to see what the Evercool looks like in the dark. Itâ€™s glowing red and blue, and I think itâ€™s probably enough quieter than the stock fan, that I now notice the other fans more, or maybe the stock fan wasnâ€™t that loud in the first place. At least, I donâ€™t have to worry about the fan dying, and frying the motherboard while Iâ€™m not here.
