Hey guys

I just recently updated my pc with a Ryzen 7 3800x, x570 mobo, Coolermaster ML360rgb AIO and some new RAM and my temps are getting pretty hot.

While idling they sit around 55-65 but while gaming they sit between 85-95. I'm not sure this is normal with a water-cooled AIO but I would've thought The temps would be a lot better. I'm currently running at the base clock and haven't overclocked anything other than the XMP for the ram to get it running at closer to 3200mhz. I suppose I'm just worried about whether these temps are normal. My previous CPU was an i5 8500 with a cooler master Hyper 212 turbo and the temps were miles better

Any help would be greatly appreciated guys

The pump block is correctly mounted on the motherboard?
The sticker was removed from beneath said block?

The fans work?

The pump works? Feel the pump block, the tubing, and the radiator. They should all feel somewhat warm - if not, there may be a problem with the pump.

The radiator and fans aren't fighting with some sealed panel for air, are they?

That's about all that comes to mind.

Thanks for the reply

Yeah, the block is installed correctly, the sticker was removed, all fans are working properly, pump block, tubes, and radiator are all lukewarm, however, there is a glass panel down the front of the case with only vents in the side for airflow ( http://deepcool.com/product/case/2019-03/9_10762.shtml ) this is the exact case. I'm going to remove the front glass panel while gaming and check temps. I would've thought an AIO would have still produced cooler temps in that Environment?

Just removed the glass panel from the front and the mesh vent cover from the top and played for a little with the case basically open except for the side panels and temps stayed exactly the same. I should also note that I'm in a hot room but have an air conditioner going literally a meter away from me.

Yikes... that's a stuffy looking case.
Removing the front and side panels was the next thing I was going to ask about too... no change, huh?

You've confirmed the AIO works.

You didn't install it backwards, did you? Ok, I think I worded that wrong.
You don't have the AIO's fans positioned inside the case, blowing air through the radiator and out the front do you?

No, the AIO is positioned on the top of the case with fans inside pulling through the radiator. I hope that's the correct installation.

Wait... so the AIO is set as top intake, you already have the front as intake... and that just leaves the single fan in the rear as exhaust?
Too much intake. Switch the AIO to exhaust - the fans are pushing air up through the rad and out the top of the case.

I've dropped the voltage down to 1.1 and the core speed down to 3.8ghz through Ryzen master and now the temps don't go over 85c while gaming even though the idle temp is still 60c. I can't help but feel like something is wrong though. surely there's no way the only way the CPU will function properly is by undervolting and running it under base clock? I'm still going to reseat the CPU and cooling block and reapply thermal paste.

holy <MOD EDIT>, boys! I had the AIO seated wrong!!!! it's running fine now. I'm such an idiot hahahaha

Thanks so much for your replies, guys! I think next time I need to accept earlier that I'm no pro and make sure I check the basics first. Sorry for wasting your time

Absolutely. When mounting the CPU fan, I attached the bottom latch and tightened it a bit so it wouldn't come off while I was trying to attach the top one. In doing so I've tightened it way too far so that when the other thumb screw felt tight, the base plate was only half touching the CPU. With the RAM already seated it was almost impossible to see that the cooler wasn't seated properly. When I removed the CPU cooler there was only a tiny bit of thermal paste on one side so it was immediately obvious that the cooler wasn't seated properly so after replacing the thermal paste, I lay the whole case down flat and tightened both thumbscrews at the same time as well as unseated the RAM to make sure it was tightened correctly. I hope that makes sense
