[SOLVED] 9900k overheating without any previous issues

[Breathless6237]

I turned my pc on today and i had to shut it down due to my cpu overheating. I have reapplied thermal paste and checked my AIO cooler is attached properly. I’m now lost as to what could be causing the issue.
My pc consists of :
I9 9900k
Rx 5600xt
Msi magcorliquid 240
ASU’s z370-p
500W - Aerocool Integrator 80+

Sounds like your AIO cooler pump failed. This is a common problem. If you have an air cooler handy, install that and see if your temps improve.

Is the radiator mounted at the top of the chassis?

The radiator is at the front with the tubes at the bottom

I have attempted to put a spare cpu In, I5 8400k and even this is reaching temps of 70 degrees C with only a browser open, am I correct in saying that the AIO is the likely cause of my issue

 

[Phaaze88]

No problems there then. People have been mounting this and similar units in the roof, which doesn't work, because the pump is in the radiator.

I5 8400

Umm, there's a sizeable difference in potential power draw between those cpus. I'm not sure that's a fair conclusion...
Do you have a spare cooler to test, as uWebb429 suggested?

not anymore, as I’d got rid of my old one, after a couple months of having my AIO, I got this AIO in may, should it be Broken already? Or could it be that I’m on the cusp on hitting the 500W of my PSU

It was not a good idea to do that. AIO have more points of failure, and thus are not as reliable as a good ol air cooler, so having a backup cooler is a must for these.
Sometimes stuff just happens.
You had it mounted correctly, IMO. It was working fine for a little bit - until it just didn't.

Before I write it off as dead:
-Have you tried the pump connector in a different header?
-Check the cooler backplate. It didn't come loose, did it?

I have tried a different header, not sure what you mean by pump header. Only benefit I can say is that Amazon have said they will send me a replacement, so could wait to see if that fixes the problem

The connector that the pump gets power from is a 3 or 4pin that connects to the motherboard, right?
If it was SATA only, that's my mistake.

Ohhh, it’s a 3 pin connector, it was initially ina cpu fan, I moved it to the designated AIO pump one, and there was no difference in temps

 

[Breathless6237]

I meant how do I check the backplate is loose, I’m guessing it would be leaking if it came loose.

 

[Phaaze88]

Ok.
Well, since Amazon's already sending you a new one, see what that does.
But I suggest getting a backup cooler - it does not have to be another AIO - if you want to stay on the AIO route.
It's not a matter of IF, but WHEN they fail.

No, not leaking.
When you installed the AIO, didn't you have to install a cross-shaped bracket or something behind the motherboard, which would support the mounting hardware on the other side?

Ok thank you so much for the quick help, I’ll keep it all in mind in case the next goes wrong, would you say it is worth getting a 600W PSU instead of my 500 as I believe when I calculated the power draw it’s almost 500 if not 500W

Quality first. Quantity takes a back seat - it also doesn't mean much of anything on it's own, as there are good and bad units regardless of what the rated wattage is.

If I remember correctly, Aerocool did a bait-n-switch; sent cherry picked versions of that unit out to reviewers. The actual retail model wasn't anything like it - it was trash.
Well, it's not the first - and certainly not the last - time that a company does that.

Thank you very much, I’ll have a look at that.

What you say is likely correct.

 

[mdd1963]

an AIO pump fails or faces degraded cooling performance from micro-fluid leaks, air bubbles, internal micro fins clogged with contaminants or just plain 'quits pumping' despite making a buzzing noise?

Who'd have thought it could ever happen?
