That's pretty much a constant idle. It fluctuates a few degrees... I don't ever shutdown or sleep the MacPro...
Here is what idle is currently, MacPro has been on for days, idling just basic OS / web usage...
Scrolling through my CaptureOne catalog uses the GPU, temps rise to around 45°C:
No worries! I don't mind sharing!
The fans on mine don't spin at all without a load on the card. And I normally have the rest of the fans running around 1000rpms (just a bit higher than the system default). I have fan rules setup in iStat Menus based on NB temp...
Thanks but that would mean a whole lot more if we knew what software you are using and what you were doing at the time ! also , I imagine istat just controls the case fans and cannot do anything with the gpu fan, is that right ??
