There seems to be no difference in cooling performace with the attached fan at high and low speeds which seems a little odd. The base is always cool to the touch also (even under load).

I guess I may have to consider lapping.
Thanks - sounds like I shouldnt buy one of them. Before you lap check whether the CPU IHS surface is already even or not. A drop of water on CPU and then put a plate of glass on it. Check even spead or not. I lapped and it made not a jot of difference on the e6600 as it must have already been flat - looks nice though! if you want to try there is a guide on this site http://www.thetechrepository.com/
and a lot of other useful stuff such as MBM5 v 2
