I have a rayteck look here http://www.raytek-northamerica.com/cat.html?cat_id=2.3.5 this is what it is when I check the temp of the GPU on a 1.0 or 1.1 it is only 38-45c but on the 1.4 and the others that dont have the cooling fan on it but have a larger heat sink it is 51-67c and that is a huge difference does anyone know why (I have tried it when I turn off the cooling fan off for a second just to check the temp I thought that it was because of the cooling fan that is was cooler then it was still the same and if I lef tthe fan off then it went up slowly)
