GPU running hot after boot

[Bamise]

Hello,

I have an i9-12900H, RTX 3090, 1000w PSU and 64 GB of ram. For a few weeks now, I have noticed that when I start my PC, the GPU (3090) runs hot, usually before I begin any task for that session. If I start any application or try looking through the Task Manager, it stops and returns to a normal idle temperature. Can anyone help me find a solution to this? Thank you

As far as I know, components heating up during boot/POST is normal. How hot are we talking about?

That's a bit on the higher end, but considering you live in a hot climate, it isn't all too bad.

 

Do your GPU's fans spin up during boot, and what's your idle temps?

Not all the time, idle is 43°C

What about when under pressure with gaming or stresstesting?

Those look like normal temps for a high-end GPU. I think you're fine.

Thank you, still worried about the startup temps

I may have figured out what was causing the GPU to ramp up unexplainedly. Using Taskmgr, I tracked it down to Intel Driver Manager and uninstalled it. Ever since then, I haven't experienced the random spikes in usage.
