From a thermal pads point of view it seems the EK block has a better design, greater flow rates, GPU temp and VRM temps! I only wish the EK block could use all TIM as I believe since it beat the DD block in the thermal pad area, if it were possible the EK "All TIM" would have been incredible! Me personally I wouldn't touch the restrictive blocks so that leaves only two, the Danger Den and EK FC 480 GTX water blocks. I couldn't imagine running three of the restrictive blocks in Tri-SLI after everything I've learned so far!
