Corsair h100i Suddenly Stops

[ariliteth]

Hello everyone,

I built my PC earlier this year and it has been running great for months. My build:
CPU: Intel Core i7-6700K 4.0GHz Quad-Core Processor ($339.99 @ B&H)
CPU Cooler: Corsair H100i 77.0 CFM Liquid CPU Cooler ($119.89 @ OutletPC)
Motherboard: Asus Z170-A ATX LGA1151 Motherboard ($150.99 @ SuperBiiz)
Memory: G.Skill Ripjaws V Series 16GB (2 x 8GB) DDR4-2400 Memory ($49.99 @ Newegg)
Storage: Samsung 850 EVO-Series 500GB 2.5" Solid State Drive ($148.89 @ OutletPC)
Storage: Western Digital BLACK SERIES 2TB 3.5" 7200RPM Internal Hard Drive ($117.99 @ Micro Center)
Case: Corsair Carbide Series 300R Windowed ATX Mid Tower Case ($49.99 @ Newegg)
Power Supply: EVGA 750W 80+ Gold Certified Fully-Modular ATX Power Supply ($84.99 @ NCIX US)
Optical Drive: Asus DRW-24B1ST/BLK/B/AS DVD/CD Writer ($18.89 @ OutletPC)
Operating System: Microsoft Windows 10 Home OEM (64-bit) ($83.89 @ OutletPC)

Last night I was playing Rocket League, when all of a sudden the fans on the top of my case (as part of the CPU cooler) ramped up to maximum. I immediately quit and checked the temp of my CPU and all cores were around 95-99 degrees, so I turned the computer off. I gave it a little while, turned it back on, and the coole over my CPU was lit red, and the system wouldn't boot.

I restarted again into my bios and it gave me and error saying cpu fan speed error detected, ensure it is on the cpu fan header or adjust/disable fan speed low limit option in uefi bios.

The solutions I've seen have been about people building their pcs and plugging it into different pins. I've been running my system for months.

I tried taking the cooling system out and making sure everything was hooked up, then tightened it back in. Same issue. Watched the heat on my bios rise from 30s to 60s, with no sign it would stop.

Is my cooler shot? What else should I try?

If you have a spare air cooler around that is compatible TDP and mounting wise for your Skylake platform, use it and see f the issue persists. I'd ask you to look into the pump of the AIO, placing your finger on the CPU block can give off an indication of if the pump is working. If the AIO is faulty, you may want to contact the seller to see if you can get an RMA.

On another note, have you made sure your BIOS is up to date?

The cooler isn't shot, it's more likely the pump has given up...or so it seems, from your post above.
