Long term solution, sounds like you need more air flow in your case. If that side door can fit a 140mm fan, consider getting one. That is the best option to cool a GPU that doesn't have a blower fan.

Unfortunately it does not as it is a glass panel. I will try and jerry rig my AIO to mount at the top of case but I dont see that happening due to the lack of space.

That cooler looks better than mine but I have older i7-4790K CPU 4GHz. Did you test the temperatures with open case? It could also be that the cooler isn't mounted properly. Also some have a gummy thermal grease glued to it from factory. It needs to be removed and instead use a thin layer of some standard thermal grease.

Also make sure that the cooler is mounted so that the fan blows air from front to back, and not from down to up. The position is important for heat pipes to work properly. They needs to be vertically so that the liquid inside them could circulate, since hot liquid rises. To be hones, I don't remember if it's even possible to install it in wrong direction.

I have the same problem, got a 3700x with an h150pro and a 1080ti. the cpu goes up to 60°C in prime95 and with folding it jumps right to 75°C. gpu is normal at 60°. dont know where this jump comes from, despite prime95 stresstest on all 16 threads is way cooler.

I have this cooler on a Ryzen 3800x. The stock cooler was OK, but average temps were a bit higher than I liked. The stock cooler was also very LOUD with high CPU use. The Scythe cooler is very quite and keeps temps down.
I have an old FX6300 that's driving my dual GPU machine. That CPU has a Coolmaster Hyper 212 https://www.coolermaster.com/catalog/co ... r-212-evo/ on it. I bought that because I overclocked that chip about 25% . It's also quite though.
That CPU and dual GPU are in a Corsair Carbide Series 500R. it has a 200mm fan on the side panel.

Prime95 exercises the integer units in the CPU, but F@h is very heavy on floating point calculations. The FPU uses more power, hence the difference. Using the HT capability further increases the power usage.

There are some test sites that use F@h because it is one of a number of applications that can really stress test a system, often more so than some standard benchmarks.

Modern CPUs self manage (as a rule) and can quite "happily" run fairly hot (by old school standards) … Intel specified Tjmax for your CPU is 100C (edited just checked - 115C was the initially indicated figure sorry) so from a CPU perspective it is well under this … Tjmax is the point at which Intel will have the CPU throttle in some way (reducing frequency/voltage) CPU will usually only force shutdown 20-25C above this … Not to say Tjmax is "safe" but it is where the CPU manufacturer feels care is needed … Folding for the most part is fairly consistent load and so once up to temperature the CPU temps remain constant for each WU - this is actually a fairly benign state, much better than very spikey loads from say gaming, and as such CPUs should be able to cope … but the important thing is to keep within your personal comfort zone (which by the sounds of it you are) and set an upper limit that you feel happy with by the various adjustments in thread.

It isn't as if there is a shortage of CPU resource at the moment … and the last thing you want is to overstress your kit/yourself and cause issues.

Caveat: I am a simple folder not a F@H member - Any mistakes are mine though lack of knowledge/understanding.
