CPU overheating; please help!

Hardware Hub CPU

I'm running a 4960K with a H100i AIO cooler. I've been running for months with no problems. As of yesterday I saw that it was running at 85-90C! I immediately turned it off and have been fiddling to try and fix the issue.

I installed a third HDD in the back of my case and moved the SATA power cables around in order to get them all to fit and that seems to be the last change before the overheating started. I thought maybe I pinched the cable connecting to the pump when I put the back panel on so I tried removing it, but the issue persisted.

In Corsair LINK the Pump is shown red and flashing, with no temperature reading or RPM measurement.

Any ideas?

Am I remembering correctly that the pump power cable can come off of the pump/block on that model?

Could be your pump
I check that out first.

I've tried unplugging and re-plugging that with no change.

have you tired to plugging it in a different port/plug. Otherwise sounds like it just died on you coincidentally

6

with temps like that it definatley sounds like there is no moving coolant. try plugging the pump into different headers if nothing, i guess RMA?

I hope you got a multimeter and two paperclips. Continuity check function and hook it up! (some resistance is okay, OL or Overload is not. 0 Ohms is bad aswell as that could mean the header is fried.)

Looks like the pump it's gone unfortunately. What you may try is to plug the pump into a different fan header on the motherboard, just to make sure the fan header didn't go bad for some reason. Good luck!

The fans all spin, it is just the pump that seems to be doing nothing.

sounds like you need a new cooling solution...bummer dood.

11

how old is the unit?

12

Good thing the new NZXT Kraken is out now.

Only about a year, or less. Trouble is I bought it at microcenter and I can't find the reciept to RMA it...

13

maybe try reaching out to corsair?

14

you dont need a receipt for microcenter. they keep crazy records and thier customer service is insanely good.
Thay probably have your name, email and address attached to the serial number of the device :P

I'm going to give them a call tomorrow. I figured they had records like that and that'll be what I probably have to do. The AIO is guaranteed for 5 years so I imagine Corsair will send me a new one.

I removed my AIO and reinstalled the stock CPU cooler from intel... 94C reporting in speccy.

This makes me think it is the CPU itself? But that doesn't explain why Corsair Link reported the pump as doing nothing.

Any other theories?

try reseating the cpu and fresh TIM

18

I did that when I swapped the coolers

19

do you have an OC on it still by chance?

No, it's set to stock. The only thing is the turbo boost but that shouldn't have kicked in at startup
