    Other then the site feeling a bit outdated and in my case I needed 7950 thermal PADS and it was confusing since all the 7950 options had SP in the name. I thought SP was for paste

    A very simple experience. It works! This was purchased for a Dell slim ECS1250 it just worked. Thank you Note: Don't purchase this from anywhere else as it will not work as it's wired incorrectly.
