Yep used SIW and WinAudit, just looked at ATI Overdrive in CCC and after 5 hours + 2 hours IM with many pics looked at my 5970 is steady @ 47 / 47 but saying that I do have some serious case cooling that does help even when the GPU is enclosed, and keep in mind room temp has its part to play as we are still in Winter in the UK and the heating is on ... left to the wife it would be like the tropics in our house
