H100i Block Failure(?)
H100i Block Failure(?)
I've used my h100i for some time now and have been satisfied, but lately my computer temperatures are rising quickly and it's crashing. I've re-applied thermal paste, which hasn't made a difference. I also removed the block to check, and the CPU (8320) felt relatively cool. The copper base of the h100i was extremely hot, while the rest of the components were cooler. What's going on?
The pump is responsible for this functionality. As a mechanical component, it tends to deteriorate after several years and extensive use. What might be causing issues? If the pump ceases or the flow rate it’s meant to maintain decreases, temperatures may rise. However, it’s likely similar to a system fan—if the pump is linked to the CPU fan header or a chassis fan header, you should see an error or warning either visually or audibly. This could include visual alerts or sound notifications. The pump might be failing due to low RPM or having stopped entirely. Unless it’s disabled in your motherboard’s BIOS fan monitoring settings, this should be checked. Look into your motherboard’s BIOS if the pump is connected to a CPU or fan header. Enable fan monitoring. If you’re still using the H100i solution on the CPU, or if the setup is incorrect, consider replacing the CPU entirely. Repairing pumps can be difficult and costly, especially with sealed water loops. For your safety, set a safe shutdown temperature in your BIOS if you suspect pump failure, and ensure fan monitoring is active.
