Thanks for all the replies!
Hey there,
No, it's not supposed to run at 90c when gaming.
You should defo have lower temps. Prob about 65-80c max. 90C+ under heavy CPU load. Yes, the 5800x runs a little warmer. But not that much warmer.
Is your ram running in XMP? Use CPU-z and show us the mem/spd tabs. Also what bios are you running on the mobo?
Are all system drivers, including chipset up to date?
What windows power profile are you using?
So, from what I can tell, I was indeed running XMP 2.0. After updating the chipset drivers, I saw maybe a 1-degree average improvement, and the lag spikes stopped. I am currently using the High Performance power plan.
Pure Rock Slim is to tiny for a 5800x!
What's the brand and model of the RAM and what speed does it run?
RAM is generic G.Skill Ripjaws V 2x8, which seems to be quite common from what I can tell.
I also agree CPU cooler is kinda small for the 5800X, but what could be worse than a small cooler is a bad pc case (airflow wise).
Have you tried to run games without the side panels? If cpu temps are lower that way, and games stop lagging, then you may have to work on your case to make it better for airflow.
Sometimes do help to do a load default settings on BIOS, then download and install the newest version available ont he mobo page, and then do a new Load Default Settings. If that fix it, then you can try to enable XMP/DOCP later.
After clearing the CMOS using the button on the back of the motherboard, I saw a significant improvement in temperatures, dropping from a constant 89-90°C to an average of 85°C, with occasional spikes to 90°C. I also tried gaming both with and without the front panel, and temperatures were better with the case closed, so airflow likely isn’t the issue. After re-enabling XMP, the temperatures stayed about the same or slightly higher.
I forgot to mention earlier that my motherboard is a B550M Steel Legend. Since I know now that 85°C isn’t acceptable for gaming either, what else should I look into to reduce temperatures?
I’ve attached a picture of the inside of the PC (please excuse the dust and mess). I’m not sure whether each fan is set to intake or exhaust, as I didn’t build this system myself.
