as part of a test series (still unfinished) I have looked at aluminum and copper bps of different thicknesses mounted on 'The King of Testing Waterblocks', an old style MCW462

Some performance predictions based on "my best fit model" for your Swiftech 462u data presented here http://forums.procooling.com/vbb/sho...5&pagenumber=8. Used a T/W value obtained by allowing 0.05 c/w of the TIM(C/W) for the offset of the die tc.
Best fit calculated assumming the turbulence created in a 6x6mm square entry nozzle is maintained over all the wb base. From the Reynolds number calculating the Convection Coeff (Sieder-Tate) and then adjusting the effective Convection area. :


The "best fit 80x80mm" .is larger than the internal base area but.............

Showing the predicted effect at diiferent flow rates of Cu and Al bp thickness and the change to the new smaller AMD (80sq mm ) die .






Edit: Added C/W v Thickness curves for 8x10mm Die
