Hello, I'm experiencing thermal throttling on my PC and it's getting quite hot.
I'm using a R9 5900x and an XLR8 3080.
My case is the be quiet! pure base 500FX Tempered Glass ATX.
Idle temperatures are around 40°C for the CPU and about 50°C for the GPU.
From the image, I usually leave the side panel off; otherwise, when it's on full load, the CPU reaches roughly 85-90°C.
It seems the NH D-15 cooler can handle the 5900x well, but it doesn't appear to work effectively.
I believe the problem lies with how the CPU and GPU heat up together—Cinebench only reaches around 70°C.
I'm new to PC building, any advice or solutions would be greatly appreciated!

your rear fan seems to be drawing air from the back, but the hot air isn't escaping. consider replacing it with two slim 120mm fans or slim 140mm fans in the roof of the case to push air out. having two fans in front pulling air in, one rear fan pushing air out, and two in the roof helps maintain a cool temperature. the overheating issue arises because heat can only escape through the top, which is facing inward rather than outward.

or 2 140s in the top but space them out with one pushing air before the CPU cooler and another above it drawing hot air out.
BUT 1000% increase the fan at the back of the case to expel the heat!
Also verify the direction of the CPU cooler fans – the front should draw in air, the middle should push it out, and the rear should expel it through the second fin stack.

Above all, rotate the fan at the back to expel the hot air! That’s essential!!
Verify that the CPU coolers are set correctly!!
OHH, and double-check running the CPU cooler fans in the CPU header on Mobo (a bit of a tricky question, but it’s always worth confirming).
Test your temperatures then—if necessary, add some fans at the top, but keep in mind: more fans mean more noise. If you’re overloading with fans for minimal benefit, it’s a waste.
Consider tweaking the fan curves too!

If correcting the rear case fan direction doesn't resolve the issue you may need to re-mount (and re-paste) the heatsink. Use less than you think you need.
