CPU Cooked ?

[T1up]

Hello,

I had.. (rip) a i7 6700k when dropped onto the market around 2015, I upgraded then gave that PC to my dad a few years ago. I had some issues with the pins on the MB but solved the issue with steady hands and tweezers - everything has run smoothly for the course of the time its been in his hands.

Until today. The CPU fan is water cooled via Corsiars H45. At first I thought the Paste was old. So I re-applied. Yet the CPU instantly goes 100C. (before shutting down) Now I have fans on ideal temps. (40% speeds) today I noticed fans were running at 100% (god knows how long this CPU has been throttled at these temps, but my guess its' been cooking itself)

I jumped in the BIOS turned off OC settings to stock, did an auto boot test from BIOS... Failed. The PC does not boot on its own. Further the Ghz drops 4.8 > 2.1 even 0.8.

I mostly know its fried but reassurance helps lol.

My conclusion was MB is fine, connectors work and there was no codes telling me there was problems. Second, the CPU cooler, yet paste spread seemed good (used Kryonaut last applied 2y before today) and connection must've been fine as fan speeds didn't ever peak, there's still one hot tube, one cold so that's correct plus the fan is newish too. Thus it could only be the old boy? - squeezing the last bit of processing power out. Right ?

Any thoughts would be appreciated and F's in comments if you also feel it's purpose has been served. haha.

Thanks T.

It's likely that the pump in the AIO liquid cooler has given up the ghost (as they have been in the past with certain AIO water cooling solutions), so replacing that should get the system back into working order and not causing the system to do an emergency shut down due to going beyond safe temperatures.

Might be a dead aio pump. Do you have a random air cooler laying arround you could try?

Since you both said the same thing I maybe should consider this, However that was a new pump I bought just over a year, how common is it for it to fail. I had stocks and air coolers last longer... @Darknighterror @demonix00

it's not common in quality aio's, but it happens. when you say it keeps dropping clock speeds, and shutting down at 100c, this sounds like thermal throttling/protections, not a dying cpu. i definitely second it being a failed aio.

Wow okay great the i7 lives to tell another day. H45 from corsair must have been faulty.
