How does TOP cards compare to Twin Frozer cards?

I heard the 7950 TOP card has issues with the heatsink not touching or spreading the heat as it should and the entire card hits the 100s. Is this true?

Hi StarBound,

We have one here at our offices. I will set it up quick and test it under load.

Where did you hear that?

Hi Guys,

With the fan running at 29%, the card barely broke 71°



And at 100% fan speed, after 47 minutes, it was stable at 55°



So to answer your question, no, it is not true.

I still want to test it for myself. You'll just have to send me one to confirm....
