Hey everyone I need some advice on my Raven RV02. I've been having a lot of fun overclocking my dual 7970's. In the process however, my voltage bumps cause the cards to jump to to 55C/60C on full load in FurMark (1.20V). Obviously these aren't horrible temperatures, but I'd like them to be lower if at all possible, especially since I'm planning to jump to 1.23V-1.25V.
Currently installed in my rig is a Magicool triple 180mm radiator, as well as an XSPC EX120 set up as an intake on the top of the case. I wanted to stay as Silverstone as possible, so the EX120 has a Silverstone fan mounted to it (45CFM, 1.00 mm H20). While it was dead silent and great performing at stock clocks, I feel like I'm wasting my 120mm fan hole space.
Basically my question is: would I benefit from swapping out the EX120 with a higher density 120 radiator (like a Black Ice GTS), replacing the fan (Gentle Typhoon 2150), or both? I'd like the radiator to be as thin as possible. I could probably go as thick as an Alphacool XT45 radiator; I feel a UT60 would be pushing it in terms of asthetics. Replacing the fan would be my favored option, as I would have to drain the loop to replace the radiator, but if the temperatures would be significantly better I'll definately do it.
Pictures are attached to help you see my rig (and because I love showing off!)
