I've recently put a delta v3 waterblock on my 920 d0, and while in Prime95 stress testing it two of the cores are ok at 75degrees (Core *0 & *1) and two of them are hitting upwards of 85 =/ This means I must have screwed on one side of the block tighter than the other (I did try to get them both on right, but there you go). Does anyone know where each core lies physically under the heat spreader? That way I don't have to faff about with my head in the guts of the machine testing the thing out.
