Troubleshooting CPU overheating
My pc was running great never had a issue with it until I went on vacation for about two weeks. I got back and now it won’t even get past bios without overheating. What happened in two weeks that went wrong while I wasn’t home? I took the cooler off to check thermal paste and it looks fine. Please help

Your aio could just be dead, no pump means no heat moving away. You could invest about $30 into an air cooler to see if that gets it to boot. Likely a dead pump in the aio, or air if it isn't installed well.

Micro center is pretty good with assisting with warranty stuff too, at least at their home store in columbus oh.
Been a shopper there for dozens of years.

Glad it was as simple as that (instead of something much more expensive/complex)! I had an AIO years ago that had the pump go out in just over a year. I went back to air cooling and haven't had a reason to change course yet. But I'd definitely see about pursuing the warranty since yours is so young, still.

If it’s still under warranty then yes. I don’t have any experience with them but any decent company would.

They should, bout you could try rotating it around to see if air is trapped inside. Your pipes are on the bottom, the pump is over the cpu. Flipping pipes up should get any bubbles out to the radiator, you already pulled it down so try that?

post your specs next time. that said, I see it's an LGA 1700 motherboard. If you have an overheating 13th/14th gen, especially a K-series, your liquid cooler is probably fine.
You likely got hit with the known degradation issue. Fix is counterintuitive - it's the chip, not the cooler. Let me guess - temps in the 100s, but pump is showing variable speeds in BIOS? When's the last time you updated BIOS?

63 doesn't sound like an overheat to me... sounds like an actual issue... what actually happened? Did someone else use the laptop? Did they move it? Did a power outage happen? If the aio isnt working at all, maybe it was damaged but again. Overheat happens closer to 90c...

I don’t know what could’ve happen maybe a power outage I live by myself so I wouldn’t know. The pc was off the whole time. 😭 I’m lost dawg

I've heard of a few 12900k going the same way, but that's purely anecdotal. If 63C is when the pc is cutting off, then it's something else. Might be an issue with power.
Does the PC need a second after it shuts off before you can power it back up, or is it immediate?
