Core Distance to TjMAX randomly spikes to 100°C in OCCT (lemmy.ml)

Recently I tried to clean my PC with an I5 11400F CPU. I removed the GPU and wanted to remove the CPU cooler too but couldn't do it. I tried though and I think I might have damaged the motherboard with a screwdriver in a few places during the process (don't ask how). Can it be the reason for the spikes? Like could I damage some sensors and now they sometimes fail and show 0°C (which is what 100°C to TjMAX means)? There are no other visible issues with the PC though so I guess it can be a just a bug. Btw I can't add screenshots because of some weird Jerboa bug

So what you're suggesting is that it's not the actual temperature but rather a sensor issue? Could be, the problem is this:

remove the CPU cooler too but couldn't do it

CPU coolers have one job, and there is only one way to properly attach them. Any tempering with that system will have big consequences. If redoing that doesn't fix the issue, and you notice no other problems at all, might as well be a sensor issue.

Well then I guess I don't have a PC anymore because I can't get it repaired any time soon. Thank you for help though

You sound like you'd be able to figure it out, I'm sure if you look up your cooler on the web you'll find video and instructions. If you have cooling paste available I'd say go for it.

The problem is that the cooler is absolutely massive (because cheap materials = bad heat conductivity = more volume required) and the screws are unaccessible unless I remove the motherboard and its radiators (and I'm not even sure in that). I can try but I know I may not be able to reconnect the cables (the case is not cable management friendly at all). And also I have a physical disability so I can't do anything like that myself anyways. Oh and the cooler is some kind of noname ODM manufacturer I think so finding instructions for it is hard or even impossible
