The model of GPU I got is in the sig, and I also did a review for it. The thing is I think the bearings are shot in the fan on my bottom card, it makes a clicking noise randomly at low speeds. I originally thought something was hitting it but its not. I'm out of ideas as to troubleshooting it and now I am just looking to replace it. They are less than 1 year old, and I'm not really sure what kind of warranty HIS has or how long it would take to RMA it. But the fan is obviously junk if its going bad already. I did have custom profiles setup to cool the cards better, because I have to in crossfire or I will burn these cards up. If the stock fans on this model can't handle the increased speeds, then I need to find a fan that can and one that will last a couple years at least.
