I was running some benchmarks locally and noticed the temps much higher than usual. It’s a Founders Edition Spark. Ambient temp is about 25 degrees C. danny@toad:~$ paste <(ls /sys/class/thermal/thermal_zone*/type) <(cat /sys/class/thermal/thermal_zone*/temp) /sys/class/thermal/thermal_zone0/type …

Yeah, I had intended to print something like this from a contributor here that sucked air through it, but hadn’t gotten around to it yet (and since it has so much clear air on every side, I kept telling myself I shouldn’t need anything). Since restricting the GPU to 2200mhz it hasn’t gone above 80c…

Mine started this way - only a few failures, so capped the clocks, then a few more failures. It was progressive and makes me believe the early builds used a thermal paste which degrades with use. The forum is seeing more of these reports as later buyers have accumulated hours. Heavy prefill is where…

“ Is 94.6c too hot? ” Yes. Put a fan direct in front of it. Be extremely cautious of plastic wires and combustable materials around the unit.

[image] Drew_the_AI_Guy: Yes. Put a fan direct in front of it. I already had a fairly powerful desk fan (Meaco Sefte) blowing over it when these temps were seen. Things have been better (mostly below 80, but sometimes hitting 83) since I added the gpu clock limit, although I’m also not certai…

[image] azampatti: Give that a test :) I’m currently running with clocks set to 300-2200. But I’m trying to understand if I should be concerned with the temps I’m seeing (for ex. some people have mentioned a bad thermal paste job). I don’t want to hide the issue and then go out of warranty i…

Definitely understand your point. If you read about GB10s temp issues in general (not just nVidia DGX Spark), you’ll see people reporting sub-par thermal paste jobs. And that’s actually true to (maybe) 90% of the products that use thermal paste out there in the industry, at least consumer products. …

[image] azampatti: My guess is that the last few hundred Mhz were required to reach that 1PFlops of the advertised performance I could believe that - although I don’t understand why they wouldn’t just ramp the fans up more. It seems like the fans are barely doing anything, and I’d rather a bi…

What are normal temps under load? Is 94.6c too hot?

Try installing Sparkview — GPU monitor tool with GB10-aware unified memory handling

That would log any failures and the cause. I only had ONE shutdown and it was due to CPUHOT, not GPU

FYI: this is my spark now, Ambient temp at 20 C
