BIOS says CPU is at 100*, even after fresh restart with startup programs; fans running full speed.

Hey folks! Hoping for some insight.

Walked into the room after a nap and my fans were full speed (they've never been full speed). Restarted, checked BIOS and apparently my CPU is at 100*, but only startup processes running.

New PC, just built it last month. No problems whatsoever until now. Even while gaming, temps never reach anywhere near 100*, and fans are never maxed out.

Windows 10 Anniversary
Motherboard is a Gigabyte Designare Z170
CPU is an Intel i7 6700k
CPU cooler is a Thermaltake Riing 360 AIO Water Cooler.

I've scoured for answers but can't seem to find relevant information.

The Designare motherboard has an error LED and it reads "04", which has no entry in the manual. That said, I assume it reads "D4" and it's entry is "PCI resource allocator error. Out of resources."

Thank you for your time!

EDIT: I should also add that things seem pretty sluggish. I just noticed now, but CPU usage is at like 4% according to Task Manager.

Ok, just try another CPU cooler and report to us. ^_^ It doesn't have to be a great one, just something for LGA1151 and that will cool it down until your AIO is proven to work. ^^;

Hello there.

I would check if you have water circulation. Do you hear your water pump? Does the coolant seem to flow?

If your CPU is actually overheating because of a failed pump, it will throttle down, and everything will go slow.

I've actually never heard the pump, so I'm not sure I'd recognize the sound - the whole thing is super silent.

I did notice that Windows Defender seemed to update about half an hour before I noticed the problem. I tried to do a scan as it prompted me to but the PC froze and shut down. I guess that could mean many things, including no circulation!

Are there other ways I can check the water circulation or CPU temps besides the BIOS?

Oh also, I should add that the cooler is All in One so I can't see the coolant to see if it's flowing

Hmm, you could try holding the water cabling like a water hose and power on the pc. If you feel no difference when it's powered on, then the pump might be defective.

If your BIOS gives you 100C, then don't look in windows. ^^ The BIOS is completely unrelated to windows. At 100C, the i7 will throttle thermally, meaning it will run at the slowest speed possible so it doesn't break. This is really bad, and can break your CPU, so do not use your PC, or as little as possible, until your temps are back to normal.

Do you have the original cooler that came with the i7? If yes, install it and try again?

I couldn't feel a difference in the tubing as far as circulation goes but it was certainly running hot. Unfortunately my i7 didn't come with a cooler so I'll have to go find one tomorrow and see what I can do! What a bummer!

Thanks for your help, I'll update when I know more!

yeah. Do try another cooler. It can be a simple 35 bucks cooler. Further, keep checking for any suspicious services etc. Also, download that x64 bit process explorer from Microsoft and look for any unusual Svchost.

Yeaaa it was the cooler. Picked up a Cooler Master Hyper T4 and it works like a charm. This really sucks, the one that crapped out was just under 2 months old and now I have to find a box big enough to ship it back to Thermaltake (and pay the shipping obviously). I've never had to return a PC part before - I guess I've always been lucky!

It's too bad I can't just get a refund at this point.
