1.33ghz AMD too hot?

[andrewjm]

I have a 1.33ghz AMD and when I actually run it at 1.33ghz, the PC keeps crashing. It's around 120-130F. If I change it to 1.2ghz, it's fine.


Any ideas on how I can fix this?

I believe I have an Alpha PAL8045 Heatsink with a Delta fan...

could be a limitation on something other than the CPU..
have you tried anything other than lowering the CPU's speed?

I tried a new PSU... I have 450watts... which is way more than enough. I can't think of anything else that would be causing this though.

130F = about 55C. That is my idle temp (as reported in the bios) with an inadequate HSF. I have seen it at 75C (WOW!) after gaming for hours straight. Not to sound too cavalier about it, but I have been running this mobo/CPU/HSF setup for over 1.5 years now with the same temps and no stability issues.

And no, i don't plan on doing anything about it either. I just leave the side of the case open and blow out the dust a bit more often than I would otherwise.

Well T-Birds do run hot... but... are you sure you have proper contact between the heatsink and the CPU core? Are you using something like Arctic Silver or just that cheap thermal pad that comes on a lot of heatsinks? What is the temp inside your case? If you have bad air flow through the case, that'll cause the CPU temp to rise. Heatsinks work on heat differentials... on average, a quality heatsink with an average fan can keep a CPU at about 20-25 degrees F above case temp (speaking in terms of Athlon XP CPU's, I've never owned Intel so I don't know if the same holds true for them)... at least, that's been my experience. AMD recommends 2 case fans that flow 35 CFM each, one in front, and one in back. Most cheap case fans that you get free with a case, or get for $2 don't flow 35 CFM.

Check for adequate airflow through case.

Check to be sure heatsink is mounted properly.

Check to make sure the fan on the heatsink actually works.

Thanks for the info... I believe I have just basic thermal stuff on it, but its about a year or so old. On Monday, I'll get Arctic Silver III Premium Silver and put it on.

I have 9 fans I believe, with a perfect flow from the bottom front to the top back and top front, going over all hdds, gpu, and cpu

MOTHER OF GOD!!! Man that's hot... Oh well, make sure you get that Arctic Silver.

One thing that I was thinking........ Right now its underclocked to 1.2ghz... I change this by changing the FSB... Its really a 133mhz, and I have it set to 120mhz... The second I change it to 133mhz (The correct-clocked setting) it automatically reboots whenever I am booting up windows. It doesnt even get to the windows xp logo screen while booting. It just reboots, and then I see my BIOS again... I have tried moving it up slowly to 121, 122, but its just a pain to find the perfect spot, so I leave it at 120....


Now if I suddenly change it from 120 to 133, could the temperature all of a sudden get a lot hotter? Cause its less than a minute that I change it.
