I have an ATI board, and updated the drivers (from the ATI website) right after the computer arrived. One computer years ago came with an nVidia board and I was happy with it, but since then I've always had ATI boards because they were the top-of-the line offering at the time I was buying a new computer. With the recent posts in this newsgroup about nVidia overheating issues, I saw no reason not to go with ATI for this new computer. Frankly, now I think this fans speed-up in BIOS isn't really a problem, just a bit of paranoia on my part: is my new baby sick????? -- Nick <mailto:tanstaafl(a)pobox.com> 1.

I've had the CPU gadget on my Desktop for the last few days, and when the CPU stays above 10% for several seconds the fan speeds up a little; haven't noticed any fan speed-ups when the CPU is just idling. One time the computer got really loud: when I checked Task Manager all eight logical cores were at 100%. It's not that loud in the BIOS. As I said in my previous post, I think this is probably just paranoia on my part. But it certainly has turned into an interesting discussion. -- Nick <mailto:tanstaafl(a)pobox.com> For those who have trouble remembering the words for the song '99 Bottles of Beer on the Wall', somewhere on the Internet there's a page with the complete lyrics: all 100 verses!

Mine is the I7-960 (3.2GHz), which probably runs hotter than the slower speed versions. -- Nick <mailto:tanstaafl(a)pobox.com> .... And it was written in fiery pixels: FREE UNLIMITED ACCESS FOR ALL!!

This would be the power supply fan. Is it really the ps fan speeding up or is there just an increase in fan noise that *could* be from tne internal fan? Did you install any "power down" software when you installed the UPS? Frank

Well, when I investigated before, I was just reaching behind the computer and feeling a lot more warm air coming out of the power supply fan area at the same time I heard a fan speeding up. After reading your post, I pulled the tower out where I could get closer and listen to the fans better. Turns out the noise is actually the CPU fan, which pulls air in through the center rear grill on the left side of the computer. The power supply fan (and the chassis fan below it), are blowing more air out because the CPU fan is pulling more air in. Also, the LED's on the front of the UPS indicate a slight increase in load while in the BIOS setup, and the load and the fan speed both drop back to normal a few seconds after the 'Starting Windows' screen comes up. So I think my vote is for my original theory: some power management function in Windows isn't active before Windows starts up, so there's nothing to tell the CPU it's not busy and doesn't need to run at full speed. So the CPU runs at max speed, draws more current, gets warmer, and the CPU fan revs up to deal with the heat. >Did you install any "power down" software when you installed the UPS? Yes, but that doesn't do anything unless there's a long enough power outage to deplete the battery. -- Nick <mailto:tanstaafl(a)pobox.com> Nick's First Law of Computer Virus Complaints: Just because your computer is acting strangely or one of your programs doesn't work right, this does NOT mean that your computer has a virus. |
