Should I change my setup? Rad question...

[Radical_53]

Right now I'm using a Black Ice Extreme X-Flow triple radiator to cool my X² plus SLI system.
I'm using a dual DDC+ pump (with 15.4ft head and 2.2gpm each, so a higher flow restriction would not be a big problem) and 3 SilenX "pro 14db" fans sporting ~70cfm.

Should I rather go for a Thermochill PA series radiator or equip my BI-X with 6 fans? The additional height of the PA would be a problem in my system, as then I couldn't mount it with fans on both sides, at least then there woulnd't be much space below the fans. Which, in fact, limits performance quite a bit regarding the experiences I made with this.
I was quite satisfied with my rad until I read the sticky, saying that the Black Ice Extreme was not the best thing to go for if using low-cfm fans...
So there's the choice to go for a PA 120.3 with 3 fans, or stick with the Black Ice and put a total of 6 fans on it...

Thanks for any advice
