Pump is starting to act up again today and due to the intermittent nature of the problem I agree with the above poster; I think the pump is just starting to go out randomly.

Does Corsair cover a replacement under warranty (if anyone knows)?

In either case, I'm looking at possible replacement coolers. I looked at the H100iGTX which seems to have reviewed well and would perfectly fit the 4 fan setup I have connected now to my H100i. But I was wondering what you guys would recommend? If anything, as far as overclocking goes, I'd use the built-in Intel system that might bump my 3770k up from 3.5 to 3.9, so overclocking isn't a factor. Would I be better off going with a fan cooler?

I used to use the Hyper 212 but had problems with that, noise especially, which is why I went with the H100i for this latest build. But I know there are plenty of other good fan coolers, like the Noctua, etc. Thoughts?

ETA: I mean the CPU is at 40 degrees right now, less than an hour ago it was between 55-60 and topped out at 90 degrees with The Witcher 3 running so there's definitely a problem and it seems like the pump going in and out is the most logical answer, right?

Yes

Probably a typo, but since you called it a 3770K earlier as well, I want to point out that I'm pretty sure you have a 4770K. I remember your build vividly.

Not necessarily, especially since Corsair is going to replace your H100i under warranty. However, there are far fewer points of failure in an air cooler, if you're looking for peace of mind. Since you don't overclock, you'll get very little benefit from the giant heatsink/fan combos. You should just aim for silence. That's easily accomplished with a Hyper 212 and a different fan for it, like a Corsiar SP120 Quiet Edition or Noctua NF-F12. Or go non-PWM with a Gentle Typhoon and set it at a fixed speed. I am running 9 Gentle Typhoons in my case at a fixed 1000 rpms, and it's about 15-17db. Hyper 212s with the stock fan aren't amazingly quiet, but they shouldn't be noisy at all on a stock-clock CPU unless the fan curve is set too aggressively.

You could add any of those above-mentioned fans to a liquid cooler as well, as stock radiator fans on all-in-ones tend to be loud at higher rpms.
