i9 14900k spiking to 100+ degrees

[jonasbjornerud]

As the title suggests, I'm having some trouble with my i9 14900k overheating like crazy. For reference, it's runing on the iGPU (will be installing a dedicated 4070 TI when it arrives later this week), paired with a GIGABYTE Aorus Elite AX Motherboard, and 64 gigs of DDR5 G.Skill Trident Neo Z5 memory @ 6000mhz. The AIO I'm using is an Arctic Liquid Freezer II 360.

It idles at around 35 - 45 degrees celsius, but whenever I'm doing very non-intensive tasks such as just full-screening a YouTube video or downoading a small file, it spikes up to 75 - 85 degrees, and when I'm doing more intensive tasks such as video editing or launching games, it shoots right up to 100+ degrees and stays there without dropping.

I've done quite a bit of troubleshooting on my own - here's a quick summary:
- Ensured the plastic cover is off of the AIO and re-applied thermal paste
- Updated to latest BIOS
- Set the fans & pump head to PWM (and even tried adjusting it to max RPM)
- Connected the pump to different headers ("CPU_FAN" "CPU_OPT" "SYS_FAN_PUMP" etc).
- Installed newest graphics drivers

What's causing these temperatures?

What's causing these temperatures?
It's simple, your cooling solution is inadequate, improperly mounted and/or improperly configured.
First of all, pump lead goes to pump header and fan lead goes to CPU fan header. Don't change it. Secondly, intensive tasks should only momentarily drive temperatures near 100c. The fan speed control system (configured in board's BIOS) should be increasing speed of fan and pump to pull the temperature back down to more reasonable temperatures, even if load is sustained.
Hope the helps,

Thank you for your reponse.

I do want to point out that the cooler itself did not turn out to be the problem. I tried turning off the CPU's turbo in BIOS to make it run at a constant 3.2Ghz, and it resulted in the temperatures dropping drastically. In addition to that, I have gone as far as to de-mount the pump itself to feel for a cold water block, and it is running without a doubt - it even has a "QC-passed" sticker from Arctic themselves, and was properly packaged, so I doubt it was damaged during transport.

However, I didn't pay this kind of money for my CPU to run at almost half its rated frequency. I'd obviously not expect a stable system on a frequency that's close to its maximum, but when I get BSOD's at 5Ghz something is clearly wrong. Is it possible that there's something wrong with the CPU itself?

Thanks in advance for your support.
