Serious issues with Corsair H60

[severus]

I built an ITX machine for a friend consisting of

G3258
GA-H97N-WIFI
8gb DDR3
HIS HD7950
Corsair H60 w/ aftermarket Corsair fan
Silverstone SG13 case

Here's the problem. The H60 reads 4000RPM's in the Bios, but when I monitor the temps, the idle creeps up from the initial 60° to 100° and sits there. Sometimes I hear the coolant flowing through the unit, a lot of times I don't. I've tried remounting the cooler but no dice. The board only has a CPU and SYS fan header. Perhaps I should try a 4pin to Molex so the unit can draw power directly from the PSU?

My hypothesis: being an H97 chip instead of a Z series, and since the board only draws from a 4 pin connector, it's not supplying enough power to make the pump actually work all the time, or does this issue sound more like a faulty pump?

It's likely either the pump or the pump connection. This is one reason I'd abjured using an AiO, and the same reason that AigoMorla speaks of using a double-pump configuration to assure there's backup in a custom water rig.

You could continue to troubleshoot, trying the direct-connect to the PSU. I would assume that you set this up for thermal control of the pump and fans? That you'd either tweaked the motherboard fan-control menu, or done it in software?

I tweaked the fan speeds in the bios. Initially the bios was reporting 0000 RPM's for the pump so I thought that was the problem. I then forced it to full which is around 4200RPMS, still I don't hear the coolant cycling the majority of the time. It wasn't evident at first, but when I tried to play a non-demanding game like CS:GO, I noticed FPS was around 10-20 on 1080p low settings. This led me to check CPU temps in HWMonitor and in the Bios. Both confirm each other. I will pick up a 4 pin to molex connector tonight and try that. If that does not work, a friend of mine upgraded to an H100 and he has an H60 that he'll give me for free. Being that I am using a mITX case, it's either AiO or a low profile CPU fan, which will probably sit around 80°...

The BIOS is not a reliable method of controlling/monitoring AIO pumps. That's why they have software for that. That said, how long have you (and your friend) had the H60? The H60 was originally released in 2011 and I don't recall the original warranty length, but it's typically 3-5 years. My general mindset with computer parts is once you've hit end of warranty, be prepared to replace them.
