H100i Pump noise (video)

Hey guys,

Ive recently been having an issue with my Corsair H100i (original).

In around 4 out of every 5 boots, the pump will seem to reset itself - LED logo defaults back to colour cycling - and there is this awful grinding noise coming from the pump.

It lasts until the desktop loads in, at which point the fans spin up for a second before settling down and then everything returns to normal.

Sometimes it wont happen at all, and the Logo stays white and there is no noise, but the majority of the time this is what happens:

Any ideas / help / suggestions?

Cheers!
