High CPU Temps

Hello,

My CPU's idle temperatures are somewhat high (37C-45C) with an ambient temperature of around 22C. Also, as soon as a run Prime95 the temps run over 100C. The CPU is NOT overclocked, and the case temperatures are OK, as my AIO GPU hovers around 35C idle (but GPUs are expected to run slightly hotter than CPUs)

Part list :

Things I've done to try and fix this but to no success:
I have replaced my Kraken X61 with a new one.
Applied MX-4 instead of the stock thermal paste.

Additional Info:
3x Cougar Vortex fans are mounted on the front as intake
2x Noctua NF-A14 are mounted on the top as exhaust in pull configuration with the Kraken X61 radiator
1x Noctua NF-F12 is mounted on the rear as exhaust in pull configuration with the Kraken X31 radiator.

Thanks in advance for the help
 
Pump speed seems to max out at 3000RPM on load and how would I check if it's airlocked or not? One thing I've noticed which is a bit concerning is that the "liquid temp" doesnt seem to rise above 38-39C (although I didn't leave the test running for more than a couple of minutes in fear it would fry the CPU)

This is the 2nd Kraken and both exhibit the same high temps, so I don't think the issue lies with the AIO itself.

I've also mounted numerous coolers in my life, so I don't think that is the cause of this either. I'll attempt today to re-seat and install some washers on the backplate standoffs see if that helps at all, but I highly doubt it.
 
Tilt the case from side to side and front to back to a low angle, even lay it on it's side.
you will hear the air moving gurgling, some AIO can take quite a time to clear.

Adding washers does not sound a good idea, you could end up breaking the motherboard with the extra stress.

Thanks for the reply. I'll give that a go when I get off work and revert.
 
Have you checked what voltage your CPU is pulling? Just because it isn't overclocked doesn't mean something hasn't gone very wrong in the BIOS, potentially update that and see if its fixed.

Basically if the CPU isn't showing chunky voltage on idle/load then it's probably a cooler issue, if the CPU shows big voltage that is why its cooking itself - suggest checking the BIOS/updating to the latest version.
 
Looks like the cooler isn't working mate, have you checked in the BIOS and updated it? I'd also try another fan header for power in case your CPU OPT is faulty or somehow disabled in BIOS

BIOS is updated, and am using CPU_FAN, I'll give CPU_OPT a go see if that helps. Thanks for the feedback.
 
Seriously considering trying the Corsair H110i instead. Already changed 4x Kraken NZXT x61. First two faulty pump, and these two ridiculously high temps. I'm starting to wonder whether maybe the ceramic on the CPU and/or the motherboard might have bulged or something and causing the coolers to not have good contact with it.

I've actually just re-seated the cooler and the temps seem to be even worse 2-3C increase on idle/load.

Pretty sure my old H60 stated you should use OPT, disable the monitoring on the CPU pin so it doesn't throw a total fit thinking the world is ending. Potentially your problem so see how it goes!
