a lot heatsinks/AIOs are intentionally (a tiny bit) convex, the IHS should ideally be as flat as possible.

Just a thought, is case warm/hot to the touch when CPU is hot? If case isn't flowing cool air to cooler and the air entering cooler is 20c warmer than room the CPU will also be 20c hotter than if cooler is receiving air at room temp.

While that doesn't mean air going into cooler is room temp, it is probalby not more than 3-8c above room temp. My builds run cooler with side cover on than off.

Can't remember if you have removed, cleaned and re-installed. You said you were going to re-install your CLC. Have you done this and checked the DRP4 seat/print? I'm guessing you probalby have a bad mount/seat wiht DRP4. Maybe mount isn't installed properly, problem has to be heat transfer from CPU to cooler, it's highly unlikely a defective cooler.

Ok little update, but no solution:

@doyll : yes i cleaned all and re-installed the cooler 3 times now and like i said the TIM print was perfect from the 1st time i applied it, all screws are tight to the max. I can say the mount mechanism is installed super properly

@The Pook : i put on again the corsair AIO and the temps are back to normal... meanwhile i checked and i can say the cooler is a bit convex but very very minimal (the aio is more covex) and the IHS i can say seems a little little bit concave... but almost impossible to notice. I checked with a flat piece of steel and if i put it to direct light i can see a very very little gap in the middle but like i said almost barely visible..

These photos are from the last try, i put even more paste to see if it made any difference

Where are you mounting the AIO? If you're mounting it to the front maybe it's just that the heatsink isn't getting good enough airflow and the AIO up front does? That shouldn't cause a 20C temp difference though.

Past that I really dunno what to tell you, thermal paste spread looks fine and even if the CPU was badly concave/convex temps on both the AIO and heatsink would suck, not just on the heatsink.

The AIO is mounted on top with the fans blowing out the case... the 2 fans you see in the photo are the 2 front intakes in the case
But exactly like you said even with poor/none airflow it should not cause this huge temp difference....
Really I feel like I've been knocking my head against the wall trying to understand what's going on. I reached the guy that sold me the cooler and asked him if he can open a RMA ticket with amazon because it's still under warranty

Please let us know how it all works out. I'm sure I'm not the only one wondering what the problem is.

Ok i think i resolved the problem (if we can say so)....
The guy who sold me the cooler asked amazon to send it back with a RMA and they will refund him the price... so i get back my money and he also get some € back
No chance to get a replacement because it was selled on amazon by a third party seller
At least we get the money back but i still have to buy a new heatsink to replace my AIO but this time i am buying it sold and shipped from amazon so i can just try it for 30 days
