H80i GT pump not running CPU near throttling

[NitrixCustoms]

I woke up this morning eager to tear into some games when I noticed a quirky little issue. My CPU, on Corsair Link, is reading off as 98 degrees Celsius. I panic a little, and notice my fans running much louder than normal. I see that all my fans are on performance, and my pump is at... Zero. That's the problem diagnosed, but I ask you now, what could cause this to happen in an H80i GT, and what should I do to fix it? Thanks,
Josh

If it's connected to the PSU as it should be and it won't run, then it's time to RMA it.

This happens to the Corsair water coolers quite often.
