I've been having a tough time with my CPU temperatures after I swapped out my old motherboard for an identical model, just to have a more aesthetically pleasing white finish for my build. My computer used to idle at a comfortable 27 to 40 degrees Celsius, with gaming temps hitting around 65 to 75 degrees. But now, my idle temps are sitting between 50 and 60 degrees, and even simple tasks like watching a YouTube video bring my CPU temps up to 70 or 75 degrees. It gets crazy under load—games push my CPU up to a scorching 90 to 100 degrees, and stress tests immediately hit 100 degrees, causing thermal throttling. I've tried everything from replacing thermal paste, reseating the AIO cooler, checking for dust, resetting BIOS settings, to undervolting. I even checked all temps on other components, and everything seems normal. I'm at a loss here. Any advice? Am I missing something obvious?

Once I faced similar overheating issues for years and realized the CPU fan was installed backward after cleaning my case! Even though you have an AIO cooler, check the airflow around it—make sure that nothing is hindering the intake and exhaust. With that many fans, airflow should be decent, but you might want to double-check just in case.
Have you checked if your AIO pump is running properly? The contact frame you mentioned should help with heat distribution. If the pump isn’t working as it should, that could explain the overheating. Just to be sure, make sure it’s getting powered and functioning correctly—sometimes they can fail or run inefficiently without showing obvious signs.
Yeah, the pump is definitely powered and active. I have a readout showing it's running at 2600 RPM and the coolant temp is solid at 34 degrees. I'm actually using that contact frame already!
You could try capping your CPU voltage at 1.25V or adjust the CPU Lite Load settings in your BIOS. I’ve heard that can help with some of the heat management. Have you set your core voltage offset?
Yes, I set it to -0.075V and capped power at 253W, but it didn't help with the temp issue.
If your AIO cooler is less than 2 years old, it might not be completely out of the question that it could have air bubbles trapped in it after you reinstalled it. Those can mess up the fluid circulation. Have you considered trying to bleed the system to get rid of any potential air pockets?
Not really sure how to bleed it without making a mess. Is that something I can do safely?
I don’t actually have a traditional CPU fan, just the AIO. But I did set up ten fans in total, and it seems like airflow is good with them all set to adjust based on temperatures.
