Since a few days when I open Yuzu, I get a white screen for a few seconds before Yuzu starts normally. Sometimes it says “(not responding)” but not always. Then CPU temp goes way up (85-90°) but yuzu work as expected otherwise.
Both CPU and GPU usage are pretty low, and I don’t see a single core/thread maxed out either.
I’m not sure posting a log file would help. Would it?
In order for us to provide better support, we need to see the log generated by yuzu. This guide will walk you through how you can obtain the log file: Getting Log Files - yuzu
On what hardware is this? 99.9% of the time this is caused by bad cooling, on laptops, that’s a design choice.
R5 5600g ATX desktop (mini ITX MB)
240mm AIO
GTX 1060 6GB
When not running yuzu CPU stays around 50-55° (playing light games like TMNT, Rocket League, …)
Actually CPU temp goes up when I launch a game (not when Yuzu starts). Excuse my inaccurate description.
That’s when all shaders load up using all your CPU cores.
I would check the pressure or paste application, you shouldn’t ever get close to those temps on an AIO.
Hell, it may be the sticker is still in the back of the heatsink.
LOL, no I made sure to remove the sticker from the heatsink 
I will clean up the heat spreader and apply new thermal paste. Let’s hope for the best…
with other benchmark programs, like cine bench, or when trying to do video encoding, what temperature do you get??
yup…
Running cinebench gets the CPU temp to 95°c too.
I’ll reapply thermal paste now.
Thanks
I cleaned the old thermal paste (nothing seemed obviously wrong with it).
Applied new one (Thermal Grizzly Kryonaut)
CPU temps still get to 95°c when running cinebench 
Any advice? @malm06
Maybe I should try to get back to an air cooler (Wraith Prism RGB Stock Cooler)?
I still don’t understand why I get the white screen for several (10-15) seconds when yuzu starts and I don’t know if this is related to high CPU temps…
Try re-seating the CPU, it really doesn’t sound normal.
The white screen may depend of the game, I wouldn’t consider it something troublesome.
Yup re-seating the CPU was the key. Now Cinebench tops at 78°c
(I tried with the Wraith Prism and CB topped at 73°c so 5°c cooler than a 240 AIO, not bad…)
This is the first time I have such a thing happening to me. I don’t really understand how a CPU could be positioned in a way that would allow it to work but cause it to overheat… Bad angle → poor contact with the cooler maybe? IDK
Anyways, thanks a lot to you @GoldenX86 and also @malm06 for your help. I appreciate it
