or is that liquid cooling? What kind of video card is it?
I have a problem with my GPU temperature's since I added a second GPU. They are both Radeon-6870's.
Under load they can reach temperatures of around 90C (left one) and 95 (right one) respectively.
Here's an image showing the inside of the PC
I'm note sure how I should cool them, I see the airflow is not so good here. Would putting a fan right onto the GPU's help?
Any tips are welcome!
