CPU at 100c Idle - Please Help

I couldn't unplug one of the fans but I'm almost positive the noise I'm hearing is the pump.

100c idling on an AIO is almost certainly a dead pump like others have said. Another way you can test this is by swapping out the AIO with a stock cooler if you have one. If you don’t I would contact the OEM you bought it from/AIO manufacturer if you built it your self to get a replacement cooler. 

I started to notice a couple days ago that my PC was starting to lag and yesterday I wasn't even able to get to task manager cause it was so overloaded. I checked my CPU temp and It's consistently at 100c even when I'm not doing anything, and It won't drop. I've tried cleaning everything, reapplying thermal paste, checked the fans and nothing has helped. Any help is appreciated.

Sounds to me like your AIO might have a dead pump. To verify this, try squeezing lightly on the tubes while the PC is on. If it's working, you should be able to feel some coolant moving through. 

My System: 

AMD Ryzen 5 3600XT • Noctua NH-D15 • MSI MAG B550 Tomahawk • 2x8GB G.skill Trident Z Neo 3600MHz CL16 • MSI VENTUS 3X GeForce RTX 3070 OC •  Samsung 970 Evo 1TB • Samsung 860 Evo 1TB • Cosair iCUE 465X RGB • Corsair RMx 750W (White) • ASUS VG27AQ • Logitech G810 Orion Spectrum • Logitech G502 Hero

 

Got any questions about my system or peripherals? Feel free to tag me (@bellabichon) and I'll be happy to give you my two cents.

Does the pump work on whatever AIO that is?

Sadly the tube is braided so I can't check that way. Is there anything else I can do?

If you put your ear up to the pump can you hear it?

I do hear a sound, I'm not 100% sure It's the pump.

If you unplug all of the fans can you hear it?

Alright. I'm probably gonna have to buy a different AIO cause my warranty is expired. Thanks for the help!

I’ve had really good luck with Corsair AIOs lasting a long time, plus their warranty is really solid.

I called them and they said they don't sell individual parts and my warranty is expired. 😬
