Recently my CPU has been drastically over heating, quickly rising to 90c-100c during moderate tasks such as running a windows defender scan or playing some thing like PUBG.

I've had a similar problem a few months ago and ended up replacing the motherboard, which did resolve my problem. I suspect its the same problem again, though I don't know what caused it this time or the last time. Maybe I accidentally shocked the board while cleaning it, I doubt I could do that twice as I'm fairly careful when doing anything inside the case.

While its possible it was user error, I'm starting to wonder if there could be a short in the PSU or one of the cords. I checked the cords as thoroughly as I could for cuts/damage but didn't notice anything. Any advice?

My motherboard is still under warranty, but I was considering doing an upgrade instead. Is it worth getting a newer board to ensure maximum future compatibility, or is my board good enough. What are your thoughts/opinions/advice? I've got $500 budget for the board.

Heres a list of the things I've tried to fix the problem.
* ran a windows defender full scan
* ran a malwarebytes full scan
* done a system restore
* re-applied thermal paste, multiple times
* tried a different fan
* reseated the CPU
* benched the motherboard
* reseated the motherboard
* tested with spare RAM
* tested with spare GPU
* contacted Intel support and verified with their software that the CPU is functioning properly

I'd wager there's an issue with your cooler-ensure everything is seated and plugged in properly and the pump+fans are running

That was my first thought as well, but I've already tried a separate cooler. The fan on the stock cooler is definitely spinning and properly mounted, Corsair Link says the pump on the h100i is well pumping, and the fans on the radiator are spinning.

So even with a new cooler you get high temps? Are you sure there is no overclock running? Can you check in case one of your utilities has accidentally set one up for you? More specifically have a look at your voltages.

I'm positive no overclock has been applied, I have no overclocking software installed, nor have I messed with anything in the BIOS other than updating the BIOS and setting fan speeds to max. The voltage in the bios says it was 1.040, I think thats more or less normal. I'm not sure if its worth mentioning or not but while in the BIOS temps ran roughly 58C.

Heres a screen of HWmonitor. I ran a defender scan for less than 30 seconds to show the max values, I let the temperature cool for roughly 5 mins before taking the screen. Don't know if it helps or not but I guess the more info the better.

i think you can find your solution here https://communities.intel.com/thread/54032?start=30&tstart=0

Theres a lot of information in that thread that I've never seen before, and while the problems do seem similar I've had this processor for over 2 years with out problem, also that thread is 4 years old. I would assume the problem would of been rectified by now but the last post was in 2016 so I'm starting to wonder. :/

I tried the fix listed in the thread, changing the voltage to a constant 1.050 and disabling turbo boost. Unfortunately temperatures got worse, 80c+ in the bios and I got a cpu fan error. I panicked a bit and went back to defaults, I'm still getting the cpu fan error. I don't know what to do now I'm at a complete loss.

I don't know if its the processor now, or the motherboard, or just an unfortunate mix of the two. This is honestly a bit over my head and I could use a bit more advice if you or any one else here could provide it, what should I do next?

Until then I'll be reading through that thread, it's rather informative but also unnerving.

2 possible faults which is your motherboard or power supply.
but more possibly your motherboard bad voltage regulator or faulty capacitor cause the problem

I know this thread is nearly 2 months old now but I wanted to give an update in the event some one else has my problem, and of course judging by this link to the intel community many people have it, even if it is 2-ish years old.

I have removed every single variable that could be causing my problem from the motherboard, ram, gpu, psu, cables, case, and even the peripherals.

I've recently purchased a new cpu (a g3220) which runs perfectly fine, with no abnormal temps, therefore I have also eliminated user error as a possible cause to the problem. 60$ just to make sure I'm not incompetent. :/

I'll be contacting intel soon to resolve this problem and assuming this thread isn't locked for its age I'll update it with my results.

Finally, thank you amitsandhu for turning my attention to the intel communities thread. I've selected it, or voted it as best answer. I'm not entirely sure how that system works but there ya go.
