Question CPU heating up to 115C on start up and idling

[MarauderX]

I've been trying to diagnose whether this CPU issue is the pump or contact degradation over time. On a cold start to BIOS it will ramp up to 115C (at a rate of about 0.5C per ~1-2 seconds). Any thoughts?

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

That's a sign that your cooler is incapable of cooling the processor. You mentioned a pump, how is your watercooling loop's pump or AIO oriented in your build?

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Disk drive(s): make, model, capacity, how full?

Apologies, makes sense, but can't keep the machine up long enough to get the info dump.

cpu cooler make and model?.

motherboard make and model can be found on the motherboard.

psu theres usually a label. same with gpu

I would suggest that the cooler block is not properly mounted on the CPU.

We still need your full system specs to better help you solve this problem.

However, 115°C is far hotter than Intel's Tj Max Specification, which is 100°C. Unfortunately, your Motherboard manufacturer has included a Tj Max adjustment in BIOS that allows Intel's 100°C limit to be exceeded, which is a glaring issue that's always an extremely bad idea. Increasing Tj Max also voids your CPU warranty.

Before continuing to troubleshoot your cooling problem, please go into BIOS, find the Tj Max setting, and restore it to Intel's correct value of 100°C, so as to safeguard against permanently damaging your processor.

Or pump dead or
waterblock clogged.

Replace AIO.
