How to reduce Sapphire Radeon 7990 temp?
Hello I have a 7990 that gets uber hot. When playing BF4 my 7990 gets up to 85C. I also notice that the game drops from 60+ fps to like 10-12fps. This makes my game unplayable. Trying to minimize the heat on this awesome card. I have a new cpu cooler coming in to reduce my cpu temps. But, right now my concern is this graphics card. I do have a well ventilated case. What would be my option to fix this problem? Just crack the case open on the side and have a room fan blow into that case? Water cooling? Re apply thermal paste?
lol the room fan is certainly an option, you say your case of well ventilated but you might be able to do some swapping around with the case fans in order to direct more air onto the GPU itself, that should lower it by a good bit if you have some quality case fans, otherwise you may have to go with an after-market liquid solution.

I guess the factory don't know how to apply thermal paste. When I took the 7990 apart I was disgusted by how much thermal paste these retards put on this card. After cleaning off the thermal paste I applied arctic silver 5 thermal paste. Pea size amount just like you would for cpu on motherboard. Viola! The card is not only running cooler under load the fps in game don't drop anymore. Problem solved.
Had the heat problem of the 7990 in my card too. Still looking towards better solutions, because fans at 100% are noisy. My temps rised past 90 °C like a rocket, before I shut the loading of the card. Now I'm running 76/75 °C per core full load:
-Changed thermal paste
-Added fans to the case (now 3 in, 3 out)
-underclocked the core above PSU (850/1200 Mhz)
-undervoltaged both cores
-forced constant voltage
-added heatsinks on the backplate of the card, mine got REALLY hot and that kind of thermal mass in my mind can heat up the whole card
-aggresive fan curve
