I recently upgraded from an i3-12100F to an i5-14600KF, and although the temperature is nice and cool when idle (around the mid 30s), it skyrockets to nearly 100°C under high load. Even during less intensive tasks, it still gets pretty hot. I've made sure to apply thermal paste correctly and secured the cooler tightly, alternating the screws during tightening for even paste spread. The fan is set up properly, pushing air through the heatsink just like before my upgrade. I've even undervolted the CPU and limited its max processor state to 90% in power options, but nothing seems to work. I've ordered a dual tower heatsink for next steps, but I'm concerned there might be an underlying issue causing these high temperatures. Here's my build: Motherboard: PRO B660M-A WIFI DDR4, GPU: 3060 Ti, PSU: likely 500 or 600 watts (not sure of the brand), RAM: 16GB DDR4, and I'm currently using a single tower heatsink with one fan.

Make sure your BIOS is updated to the latest version. Try setting the cooler type to Intel defaults and adjust settings like CPU Lite Load Level to 3-4. You can also tweak the Digital ALL load line calibration to Level 3. This setup can help reduce temperatures significantly without losing performance. Test your stability afterward with Cinebench to ensure everything runs smoothly!
You're definitely dealing with a common issue here. The 14th gen CPUs are known for running hot, so you're not alone in this! A stronger cooling solution is definitely necessary for these processors.
Did you remember to take off any protective film from your heatsink during installation? Sometimes those can get overlooked and cause overheating issues.
Consider upgrading your cooling system for better airflow. That should help manage those temps better during intense workloads!
If you're still using the stock Intel fan from your previous CPU, that's part of the problem. That cooler isn't rated for the higher power of an unlocked i5. It can handle 65W CPUs, but your new chip has a much higher 125W TDP, which is why it's overheating. Your new cooler should ideally have a TDP rating of 200W or more for better performance under load.
You're looking good with that cooler! Yes, TPC rating can give you a good estimate of performance. For software tweaks, consider making sure your BIOS is up to date to help manage voltages better.
I have a different cooler that's not stock either, but I've just ordered a Thermalright Peerless Assassin 120. I noticed it has a TPC rating of '120~265'. Is that comparable to TDP? Also, is there anything else I can do software-wise to help keep temps down? I've already set my BIOS undervolt to -0.050.
