I recently upgraded to a 4k Monitor for gaming and i get decent 30+FPS performance out of my R9 390, but i feel like my PC needs a cooling upgrade now, the sheer amount of heat that is coming off the system feels as equal to a small portable heater...

I am contemplating going water cooling on the GPU, because i have an H50 setup on the CPU and i dont think the heat is coming from the CPU as it only sits around 40% during gaming mostly, the GPU is pegged to 99% the entire time.

I am a newbie when it comes to water cooling, hence why my CPU has a H50 setup on it instead of a custom setup. I am not one that needs my computer to look like a work of art, just need it to function properly as it sits under my desk due to the case being sooo large.

I have searched and find literally no water blocks available for my Sapphire R9 390 GPU, so i came across someone who installed a universal setup on his R9 390 using a NZXT Kraken G10 RL-KRG10-B1 GPU Bracket and a Corsair H60 CPU cooler all in one and claims his average temps on the GPU dropped 12c.

So im contemplating using that universal kit and install a larger 240mm or 360mm cpu cooler all in one kit on the GPU since i have the space in my case. Heck i only have 1 x 200mm fan installed on the top of the case with the ability to installed a 2nd still there. I dont see a 200mm water cooling kit or i would go that route.

1. you GPU is working harder for 4K - more heat
2. the monitor itself can get very warm.
benchmarks mostly put unrealistic load. your temperatures are fine. Just enjoy your 4K gaming.
your GPU is ~275watt TDP - that's kinda a lot. modern computers with i5/i7 + GTX 1080 have lower total power consumption than only R9 390.
you don't have much to do about heat output from your computer beside upgrading to much more power efficient card and putting AC in your room.

The cooler sapphire installs on the 290 and 390 are phenomenal. You didnt even list what your temps are, a hot case dosent mean anything.

A new cooler wouldnt increase your performance either way, so you would be better off investing it in a new card at that point.

just to make it clear - liquid cooling will not change the heat output of your computer. I mean it will still act like a heater :)
the only difference would be components temperature.
Regarding kits for GPU - i'd not recommend AiO for GPU. they liquid cool GPU only while leaving (less important) memory and (very important) VRM for air cooling.
EKWB are soon to release EK-MLC series which is probably the only AiO that i will recommend for GPU. But to cool the GPU, expect 200+ USD price tag

Well just to give you some numbers, i ran Unigine Heaven Benchmark 4.0

FPS Average 29.9
Score 501
Min FPS 6.2
Max FPS 42.7
Settings: Direct3D11, 3840x2160 fullscreen, quality ultra

I ran the benchmark for 20 mins
GPU reached 84C
VRM reached 87C
CPU Package 48C

Weird thing is the GPU fans never exceeded 47% during the entire benchmark.

those number are perfectly fine for this specific HW.
This GPU is designed to work up to 95C. As suggested above, you can increase the GPU fans speed to a level that they almost annoy. It will lower the GPU temp, WILL NOT change the heat output from the component - same effect on the room temperature.
No idea which VRM you are monitoring, but they can easily work up to over 100C.
the CPU, Heaven does not put enough load on the CPU - sligthly more than 1 core is working.

which benchmark would you recommend i run to see results. i just noticed the huge increase in heat since upgrading to 4k monitor on the computer for gaming.
