my first thinking is about the AIO and how it reads temperatures ... maybe try to run AIO at at 100% fans constantly to see what are the temperature when it is working @ 100% while gaming
Coud you start hwinfo, do some gameplay and then take screenshot of hwinfo sensors with all values? You can make hwinfo sensors screen to show more columns with all values and take screenshot of that. It would shou max values of temperatures, fan speeds, etc.
trek - I've uploaded the screenshots of all sensors on Imgur
xlox - The AIO fans start to ramp up the moment I launch a game. Then, the moment I load a match, they reach 100% as the CPU crosses 80C, which is most of the time. Sometimes temperatures drop below 80%, but that doesn't last long. The normal fans are constantly at 50%, then 100% at 85C when things get bad. My normal fans I mean the case fans, and not the AIO fans.
From values you have shown it looks like you have defective AIO or maybe you shout reseat CPU cooler again and make sure you have good coldplate pressure and good thermal paste application.
You have everything nice and cool, only CPU is overheated, CPU current and power is nominal, everything look nice and fine so only explanation is there is something wrong with CPU cooler.
I don't see anything weird except maybe you could have 10° less with your AIO, that's what I get with a 2x240mm fans radiator...
still , try to fix it at 100% and see max temps than ... are the AIO fans connected to motherboard or are temps read by waterblock sensor maybe and fans connected to AIO directly ?
trek - I will give it another try with the thermal paste. Hopefully by reapplying it I can see some improvement.
xlox - the AIO I use has 3x 120 mm fans in the radiator. This AIO has its own hub, so the 3 fans are connected to the fan hub, then another plug into the motherboard. The AIO does have an auto function, but I use the PWM mode as the auto mode is too conservative. I will give it a go with the AIO fans at 100%, still, not sure what will change since while gaming the temps vary between 80C and 90C while the AIO fans are already at 100%.
Btw you have golden CPU, your are boosting over 5GHz with low voltages yet you have bad CPU cooling performance, worse than in my case with 15 year old Noctua cooler. Can you somehow check your AIO, do you hear excessive bubbling in pump etc?
saying to try fans at 100% is not the solution it's just to see if when they are always at 100% if the temps getting still so high or not ... if not it's just a problem of fan curve , and if yes it's a maybe a problem of AIO like trek said
understood - I'll try to reapply the thermal paste and make sure the pump is correctly placed on the CPU. Unfortunately my AIO came with that standard AM4 bracket with 2 screws. PErhaps the bracket with 4 screws would improve things. I will keep you all posted. Thank you for your help so far.
