I have the Thermal take III and had to put the fans on a fan controller cause the fans are EXTREMELY loud on the Giant III. I didnt use the pci thing it came with.
I put it on cause the fans on my 9800 pro quit working.
Without the Giant III, the temp was around 70 degrees Celsius under normal load.
With the Giant III, the temps were around 45-57 celsius.
I am looking at getting something different just because of the high screeming noise the giant 3 makes.
With the fans turned up, it never made the temp any cooler while playing games.
I also have 2 side fans blowing inward as well.
i would wait for other reviews before making your decision. Just giving you my experience with the giant III.
