I got the rear fan at H now (got my old PC in the same case with all the fans at H - Oh GOD the noise!) although is was set to M originally.
I did notice that there's air in the system though, lots of tiny bubbles in the pipes, and when I squeeze the return pipe from the rad to the res there was a few bigger bubbles.
The coolant level in the res looks full from the front but looking at the back with a torch showsthe level about 3mm lower than the top of the res.
Is bleeding the system a "Warrenty Voidable" offense?
I took some pictures (click them for big versions) - you can see the small bubbles and the back of the res in them.
