Hey! I usually ignore temperature settings since games run smoothly, but lately my 13700k is getting hot—reaching 100°C during gameplay. When idle it’s around 40-45°C with an ambient of about 20°C. I’m playing at 4K and 60 fps, so CPU load isn’t extreme enough to cause overheating. The system takes roughly three seconds for the package temperature to drop to 99°C in Cinebench. That’s not normal, right? I’ve read that idle temps are usually in the low 30s, and under load maybe around 80°C.

My setup looks like this:
- CPU: stock model without overclocking, paired with an MSI Mag CoreLiquid P360 water cooler (360mm radiator, top-mounted).
- GPU: RTX 4090.
- Board: MSI Pro Z790-P Wi-Fi.
- Case fans: three intake, one exhaust, and three radiator fans.

What I’ve tried:
1. Removed the cooler, cleaned all thermal paste, reapplied it, double-checked for mistakes like missing plastic wrap.
2. Tightened everything evenly.
3. Verified wiring and power delivery—radiator fans spin and the pump makes noise when pressed (though no vibration).
4. Reduced CPU voltage.
5. Removed CMOS battery to clear any leftover overclocking settings.

So far, nothing seems off. Could I have the wrong cooling bracket? It fits perfectly and didn’t need force. The GPU heat shouldn’t be the issue since it spikes only during CPU stress without GPU tasks. It’s definitely not normal. I attached a photo of the cooler setup for reference.

Best regards!

It looks like this has been appearing more often lately—it might be a blocked pipe. Most folks just replace it, but you can try cleaning it yourself if you'd like: I hope this assists you.

Are there any vibrations in the tubes for the cooler when it's running? It seems like the pump might be failing, which is unusual because these units have the radiator built into the radiator rather than the CPU block—checking the tubes for movement can help confirm water flow. These models are also known to experience pump failures due to significant corrosion buildup, with several examples existing. Since it's an all-in-one unit, I wouldn't suggest attempting cleaning or disassembly; consider replacing it instead.

It appears there is a slight vibration, but it's minimal.

I tightened everything until the fasteners secured. After that, I didn’t apply much more pressure.

It's still relatively new, so unexpected issues might arise sooner than expected.

Surely in some situations, yes—for example:

Using AIOs shouldn't cause such rapid buildup, but closed loops can still trap issues. Exceptions exist—some models have known problems with low-quality liquid leading to quick clogs. The MSI Coreliquids have reported this issue, so it's probable either the liquid is poor or the pump is failing. With a pump spinning at 4200rpm, you should notice noticeable flow through both tubes. If only a faint vibration is felt, the clog or pump failure is likely.

They took the pump fan cable out to check if idle temperatures changed. The temperature went up slightly to around 55-60 degrees. When they plugged it back in, there was a noticeable warming sound. It seems the pump isn’t completely off. I might look into what @emosun said about this. If there’s not enough thermal mass possibly due to a gap, using thermal pads instead of paste could help close that gap and stop the spikes. If the pads work better than the paste, it might explain the low temps. If nothing improves, I probably need to find another cooler.
