Computer heat issue causing shutdown problems

MORE thermal compound won't help. In fact, too much will only hurt. You want just enough for a thin sheet of compound. The compounds purpose is to fill any minute crevaces in teh core and heatsink so that you get maximum thermal conductivity and thus maximum heat getting the heck OFF the cpu.

I can take some off. Like I said, what's worked dozens of times in the past seems to not be working, so I figured I'd add a bit more. Wasn't double, or even a real noticeable amount, but I can take some off.

86 too high? Seems when it's higher than the default, even by 1 degree, it's way too hot to me. Esepcially compared to 4 currently running problem-free PC's.

I really have to wonder whether the thermometer isn't feeding you a line. I don't have a lot of experience with overclocking and only ever burned up a single CPU core. I think it was an Athlon 1800 and the motherboard didn't monitor temperatures, but only fan speed. It would shut down the computer automatically if the fan suddenly shut off, for example. Well, what happened is one of the two plastic tabs that the heatsink hooks to the socket with snapped off so the entire heatsink/fan assembly fell onto the videocard but, importantly, remained plugged into the motherboard and spinning. So the computer just kept running thinking everything was fine, for I don't know how many seconds, but when I got to it, it had burned to death. The user said that is computer suddenly locked up, then he smelled smoke.

So anyway, I can't say from personal experience what should happen at 85 degrees, but it seems to me that your processor should already be fried running for any significant amount of time on temps like that, from what I've read. Do you know anyone with an infrared thermometer that you could point inside the case?

In any case, if you've got a properly seated heatsink/fan with a thin layer of thermal paste (a razor blade works great for spreading the stuff across the core) your temperatures shouldn't be anywhere near that high. I know you put the front side bus speed on auto, but did you check the voltage?

Instead of setting the clock multiplier and FSB to auto I think you should set it all manually, in case it is being incorrectly identified by the motherboard. This is going to be slightly harder for your chip because AMD moved to a .13 micron process just when those chips were on the market and didn't differentiate the name, so you could have a Athlon 1900 with a Thunderbird core or one with a newer Palomino core and there's no way of knowing by looking at the product name. The problem is, the core voltage for a Palomino core is 1.75v (I think), but that's much too high for a Thunderbird core and will cause it to run way too hot. Maybe that's what's happening. You can tell by looking at the chip which core you have (thunderbirds is nearly square, while Palomino's is more rectangular), but here's a site that you can plug in the numbers printed right on the chip and it will tell you everything you need to know, including FSB, Clock Multiplier and Voltage settings, as well as what core your chip has:

You should really be worried if your processor is hitting 60 c even under a full load.

my friend's pc was running at 95 for a weak till everything burned. it turned out to be the power supply and badly mounted heat sink. he had pc club fix it, but they f-ed it up even more, so he had to pay 1000 in service mostly because he didn't want to wait for the warranty replacements.

I've also wondered that, because I've built a dozen+ PC's, including the first build of this very PC, plus I don't even monkey around with overclocking, and I've NEVER had issues like this thing is giving me.

No dice on that front. I DID find out today that my father-in-law likes to interchange whatever computer words he learns without realizing they actually MEAN something. "Download" is NOT the same as "install", "virus" is not the same thing as "spyware", and MOTHERBOARD FAN is not the same as HEATSINK FAN!

I made him check his records for a warranty for what he initially told me was DEFINITELY a heatsink fan he had replaced, and it turns out they swapped out the fan he had on the northbridge chip. While he was at the store, he couldn't remember what I wanted him to ask them to check his service records for, and I got to speak to the actual tech who serviced his computer when he took it in, and told the tech my F-I-L needs to buy a new heatsink fan for that same setup. He's dropping it off shortly, and if that doesn't work, I'm gonna assume the temp sensor isn't right, and simply up the shut-off temps.

I've already told him this is the solution we're going to take if the fan doesn't work, and he should start saving his money to replace his PC so that if/when this breaks down (if it's an actual heat issue), he'll be ready to replace it with very little downtime.

Thanks for the info on the site to run the chip info through. I'm almost positive it's a Palomino, but why not double check, right? I think one of those pics above listed the voltage it's running at, I didn't check before posting. When setting the FSB to Auto, it DID step up to 142, vs. the 133 it's supposed to be running at.

Well, I'm essentially considering this problem solved today, since I'll either get it operational at a lower temp reading with all the help from you guys, or I'll be boosting the shut-off temp so it's serviceable for him until he tells me it's time to replace his now-broke PC. I'll post what the final "solution" turns out to be one way or the other.
