The PTM supply situation with a lot of fake products around (especially from untrustworthy sources like Amazon) made me stick with Duronaut thermal compound. It got good ratings for direct die usage and durability and is actually still somewhat reasonably priced. I’ll see if that was a mistake but a few months in and everything is still ok. I lost some thermal performance rather early on but I assume that was through settling of my custom cold plate, making the interface with the dies a bit less optimal but I am still quite happy with how it keeps up.
The Grizzly PTM appears to be a bit challenging to apply properly, requiring very even, non-slanted, pressure during set-in.
I am running ComfyUI since a few days and had multiple instabilities, infinite hangs and segfaults - (but it depends on workload). I noticed the sensor “temp4” easily ramps from 40 to >80C in seconds.
While monitoring the situation I reached 98.6°C while the back of the Framework mainboard was at 51C. At the cooler I could not find any spot >40°C with the infrared.
Can you tell if that behavior is identical to your situation?
It seems to ramp up that fast, that the fan is still off - it should range from 45°C @ 25% to 65°C @ 100%. Maybe the default “composite temperature” setting in BIOS is bad?
If it would be an improperly applied (isolated) TIM as above, you would literally almost instantly go to 100*C in any workload, not “in seconds”.
Also going to 100C should not make you segfault or have instability otherwise, the system is supposed to be able to work at 100C for 24/7; it would just thermal throttle voltage and degrade performance. I haven’t used ComfyUI but either it’s a hardware issue beyond cooling or something wrong with your OS/ComfyUI.
It takes about 15s to go to from 28°C to >90°C. I would have assumed, this points towards a bad transfer to the heatsink. Anyhow, if I set the Fan to permanent 100% I get up to max 70°C also running more than 10mins on a job.
When I just leave the desktop running with nothing just basically idle I am around 50 degrees Celsius. So a bit dissapointed I would have thought it would be more like 30-40 degrees…
It depends on what CPU governor you use. a Power saving governor or power plan can be 30-40 at the expense of power budget (and therefore peak frequency). Whereas a performance governor will be 50C at idle but a bit fast due to the increased power budget for both CPU and GPU.
Not entirely true, the cooling system also can be to blame here
On both of my Minisforum machines the temps are at least 10 degrees lower than on my Framework Desktop, both idle and under load. All of them run Fedora in performance mode
For example, right now Minisforum 1 has average temp 35.5, Minisforum 2 - 30.1, Framework Desktop - 45.3. The ambient temperature in the room, according to Home Assistant, is 20.7
Here is my story related to that. I had thermal issue. My fan was not hitting the right RPM. Took quite a while to figure out there is a switch under my fan to change it from like quiet, performance and ultra performance. Fan was running at half speed. I feel like an idiot but at the same time, I’m surely not alone to have made that kind of mistake.
Same, my 12-year-old i7 was running at 30-40, while my FW Desktop is around 50, same as yours. Still not sure if it is normal, or they didn’t apply the thermal pad properly… and might need to be changed.
I’m seeing the same issue with my Framework desktop. Under load it shoots from 25-35C to 75-85C in less than 10 seconds. Under consistent load it then drifts slowly above 90C. @Eagle how many machines have been impacted by the foil issue? The behaviour I’m seeing is exactly the same.
For the foil issue? I’ve only seen the ones listed in this thread, personally. Is your machine thermal throttling? Have you checked that there’s no foil and that everything is properly seated? Give our support a shout and we’ll help troubleshoot. Make sure to include your OS and BIOS version.
Thanks, Iv’e sent a support request over. I think it is throttling, but it’s hard to prove that (for me). I can say the temperature gets dangerously high and shoots up rapdily, which aligns with there being a thermal issue, most likely caused by the foil being left on. Everything seems properly seated, but I haven’t removed the heat sink for obvious reasons.
