Opteron 170 maximum temperature?
I'm running my Opty 170 at 2.8G, stock heatsink and fan. Seems to be running stable in my Windows environment, but I have had a couple END_UNIT_EARLY errors in my folding logs. So I juiced up the processor to 1.6V and so far, it's been running fine but ASUS Probe II is reporting the CPU temp at 59C-62C under full load.
I Googled to find varying info. One report said anything above 50C is too high while another said that the Opty 170 can run as high as 70C max with no issues.
I should probably buy a better heatsink and fan unit, but heck, it's running! Should I be concerned?

It's huge though
But if 70C is the acceptable max and I'm not hitting anything above 62C at max load, maybe I'm in the safe zone. That's what I'm trying to find out.
Personally, I think 62c is a little warm. (my 2 Intel furnaces are running cooler @ full load) Could you list your specs? Could be your mobo reads the temps high in which case no probs. I only sugested pulling the side panel off as a quick check of how well your case cools. Even with the little funnel on the side panel, if your case can't get rid of the hot air inside, it's not doing any good (the whole pressure differential thing).
I guess what I'm trying to say, is if you can drop your temps for less than 20 buck and some elbow grease, it might be worth it.
So where am I going with this... Well, I'm thinking about removing the heatsink off my Opty 170 and checking for the same problems. I might be able to get my temp down by lapping my heatsink and adding a little more thermal compound.
Core System Specs:
Opteron 170 @ 2.8G
Stock heatsink/fan
ASUS A8N32-SLI 939 Motherboard
2.0G Corsair 3500LLPRO Memory
eVGA 7950 GX2 Video Card
Xfinity 600W Power Supply
Let us know how it works out.
(Don't tell anybody, I have OCed a little on stock sinks before, just had to keep a close eye on the temps)
No bravery needed for lapping unless you are using a power tool with an abrasive that is too course. Best way is just to wet-dry sandpaper with a few drops of water and to keep working your up to finer sandpaper. VERY fine sandpaper to finish with.
Are you talking about lapping the heatsink or the IHS?
Not sure how much heat it could take above that! Which is sad but it is running at 2.7 now - tops out at 52C thats with prime95 running - produces more heat than just folding.
AMDs run hot, Optys even more so. My 170 gets a lot hotter than that most of the time, though I run BOINC (team The Knights Who Say NI!) flat out, 24/7 (except when I have to throttle back because the ambient temp is above 30C). My Fatal1ty mobo defaults to system shut down at 75C, and I've hit that more than once because of BOINC and no air conditioning in the room. I think that BOINC is good for at least a 20C CPU temp increase.
BTW, it's been this way for years, though it took about 9 months for me to get the cooling set up initially.
And there is no doubt that my case it moving air. It's a big Cooler Master (I forgot the model numer) with Front 120mm, two "blowhole" 120mm, provision for two side fans (I think I have one 80mm, maybe a 120mm there, because a second fan wouldn't clear the heatsink) a bottom fan (another 120, I think). The PSU is at the bottom, and intakes from the back and exhausts out the bottom.
What's made the biggest difference is my HSF which is a combination of a big (not huge, but big) heat pipe heat sink from one manufacturer, with a 120mm-sized duct from another. The duct pulls case air over the heat sink on one end, and exhausts it via a 120mm fan on the back of the case on the other end.
I flat cooked the Silenx 120mm I initially put in there. I was a bit irked until I realized it was no doubt NOT designed to be immersed in 60+C air 24/7. So I tossed another random fan in there - maybe one of the temp-controlled CompUSA fans I got cheap on closeout at Microcenter after the former closed their retail stores, or maybe an Antec Tri-Cool, because I sometimes snag some of those when they go on sale at Microcenter. I do recall that it has a bigger bearing than the Silenx, and it's held up so far, so I haven't bothered with it.
Anyway, the reason I'm so confident of my cooling setup is that the "sys" temp per my "Fan EQ" applet runs only about 6-8C higher than ambient.
Recently, I've seen some Intel temps reported as being a LOT higher than my Opty. And, like I said, my Opty has been happily working like this for years.
Probably both
