Gigabyte AI TOP Atom high temps in idle

Hi everyone,

Brand new Gigabyte AI Top atom, updated to latest firmware, stays hot in idle. Fans won’t start in idle. I have 2 pcs same manufacture date (Jan 2026) and the other one has no issue. GPU Power on the hot one is 3W in idle (50 degrees Celsius) and the one with no issue is 5W (38 degrees Celsius) with 26 degrees Celsius ambient. Tried to reinstall both the nvidia recovery image and gigabyte recovery image. Under load the temps on both units seem the same, but on the hot one i saw higher compiling times for different tools versus the cooler one (signifficant differences for example on eugr vllm build the hot one took 12 minutes the cool one 8-9 minutes). Tested with nvidia spark field diagnostics and all pass minus the connect x7 which wasn’t connected at the time of the test. I want it to run headless and with no X loaded (multi-user.target). In X with monitor connected seems to stay lower but at higher wattage (±35W vs 20-22W in idle headless). Also tried to use sunshine for virtual display as I don’t have a headless hdmi display emulator at hand to try, but unless running X fully on a monitor i cannot see any difference in temps/power usage. Any ideas, other than returning it for RMA? Thanks.

same problem , but see my fix here Thermal paste or chalk? Dropped 40°C with PTM7950 on my Gigabyte AI TOP PCIe 5.0 cluster, but I have concerns - #8 by NULL.USERNAME

In my case I think it’s not a thermal conductivity issue, mostly because the upper case is very hot, so the heat gets transferred easily. The problem is the fan management system most probably as it does not start when in idle. Under load it shows similar temps with the one that does not exhibit this problem and the fan works. Changing thermal paste and opening it is on my list if there will be issues with warranty claims. I see they have some warranty protections in place on the bottom screws. I’m not willing to open them yet because they are brand new and under warranty. Also it’s not very clear to me why one unit is stuck at 3W and one at 5W gpu power draw in idle. Couldn’t find any way to change that. But one thing is 100% sure → the fan does not come on until higher usage.

Can you share nvidia-bug-reports from your units?
