I think and im not completely certain that with refurb/90day warranty that's your lot for help. I reckon chat to Greybeard and see what he says. Did they offer any other choices? Around the same price or a £10'er more etc...?
Nope that's it only the H80 the next Cooler Master AIO they have is the Nepton 140 or the Eisberg (pricey), I've dropped a thread in the Corsair forum anyway see what they say.
