Researching FC Block for Reference 7950...

post #1 of 4
Thread Starter 
I'm looking to be getting a full coverage block for my 7950 and I'm most concerned with keeping the VRMs cool. I've seen very few models where water actually runs over the area they are located. Can anyone tell if this really needed or will just having one of the models with the copper extensions do a good job? Also, are there any brands/models that I should stay away from? I know a lot of people have very little love for koolance, so lets be as objective as possible please.

I am interested in used as well...

I've looked into this myself. Do you have a 7950 that uses the 7970 reference board? If so, a 7970 cooler should work. There are many more options available. I personally like the Swiftech Komodo (Very hard to find,) AquagrATIx and the Heatkiller GPUX3. They're all full coverage and they all have active VRM cooling.

I actually just went through this for my 7970, which was originally using a MCW82. Long story short, I wanted the best VRM cooling since I was making the switch to full cover and posts I found through googling seemed to indicate those blocks that only used "extensions" (XSPC Razor 7970, for example), didn't have stellar VRM temps. I ended up grabbing a Heatkiller GPUX3 79x0 and have been extremely impressed with the results. Even long sessions of gaming at 1.325GHz and 1.3V I don't see VRM's top 70C (core stays ~47C). That said, double check that you have a compatible PCB.
