I noticed consistently in the past 2 weeks, when I turn on my DGX Spark then left alone doing nothing (not logged on via desktop) for 2 hours, touching the unit’s top is unusually warm. After noticing it, I log on and temperature readout (via nvidia-smi) is 45C. It wasn’t like that before. Last Feb and months prior, power on boot to idle then left it alone doing nothing, the temperature is 37C. Touching the unit’s top is not warm.
I think a software update (via DGX Dashboard) this month or last month, something has changed. I recall after the much touted software update in Jan which reduced the average power of DGX Spark (by auto-power down the ConnectX), the unit did not have this problem.
Pls advise how to resolve this. The unit has no docker container running and ollama has no model loaded. Dashboard reports 0% GPU utilization and 5.55 GB of System Memory used.
Pls advise how to fix this.
Without knowing the ambient temperature in both scenarios, that different could mean nothing. 45C at idle isn’t warm. Could be colder? yes. But doesn’t scream ’ issues’ to me.
For comparison – Ambient here is 25C and my DGX Spark at idle with model loaded is CPU 40C and GPU 38C, 11.8w. A higher ambient might track higher. I have mine standing on its end with a USB fan. Performing a quantisation run it got up to 95C – hence I got the fan. No thermal shutdowns, power problems or anything like that since I have had it thought.
I have the same problem with temperatures up to 50C. What I noticed is that, as soon as I attach a monitor to the Spark and log in with my user, even if the machine is then left to do nothing, temperatures decrease.
I ran a cron job to monitor temperatures for a couple of days, as suggested in this thread. And I also annotated the log when I rebooted the machine, or stopped the gdm and gnome-remote-desktop services.
For what I observed, stopping the above services did not improve idle temperatures.
I understand that these temperatures are not high per se. But i have 3 other spark machines in my office. I set up all of them and gave them to colleagues, and none of them gets as hot at idle as mine. I did not run the cron jobs on those other machines, but when I come in the office in the morning after a night where all machines were left idle, mine is the only one that is hot to the touch (and around 50C).
Hi azenuser, I have the same observation on my unit. After I do local login, the issue goes away. If I don’t do local login (ie do remote login via ssh), this issue appears.
I’m using an Asus GX10 and I’ve noticed the exact same thing. The temperature rises even at idle when I’m only logged in via SSH, but it drops back down once I log in locally.
