The fact once bowed always bowed is a bit of a concern for future usesQuote:

On Fuzion...it seems to me you maybe best to leave it alone...as performance is close to bowed GTX
I will wait for niksub1 final results...dont forget if you bow the blocks to have a good backplate to protect mobo
BTW..excellent observations and creative thinking niksub1!!!!!!!!!!!
well im going to bow my regular apogee cus i really have nothing to loose since i'm about to mill my own block that will pwn all since it will be out of 1/2" thick copper instead of 1/4":p:
Remember when you mount it, the mounting plate comes down on FOUR CORNERS of the block. I suspect that this can slightly bend the base upward...I guess that's a big reason why the bow mount works so well, gives wonderful contact in the center where you need it. Sure with a lapped CPU it should work...:PQuote:

thicker middle + thinner edges = () <---- a convex shape
Note that the PRESSURE is now focused in the center of the IHS...Back in the old Apogee GT thread (I think it was that one) or was it the CES one? we were discussing the issue...that was one of the theories that came up, that the slight bending upwards made contact very poor. Anyways we can clearly see here (courtesy of nikhsub's camera...which is better than my webcam :P Hey I'll have that camera for free if you don't want it :D) that the bowed base is concentrating all the force near the center of the IHS where the core (s) are=more pressure=better contact :banana:Quote:

I suppose you use magic to affix your WB to the cpu? Perhaps you have little elves hold the damn things on for you? Or maybe, Ivanka Trump comes and begs you to let her apply 60 lbs of pressure to your WB? No, I bet that Heather Mills lends you her fake leg to wedge the WB into place :shocked:Quote:

EK 1/4" BSPP fitting (older version with larger collar/flange): 2.50mm (2.5mm)
EK 1/4" BSPP fitting (current version with smaller collar/flange): 2.43mm (2.4mm)
Swiftech nickel plated brass 1/4" BSPP fitting: 2.62mm (2.6mm)
Danger Den 1/4" BSPP "high-flow" fitting (older version w/thick o-ring): 2.55mm (2.5mm)
Danger Den 1/4" BSPP "high-flow" fitting (current version w/thin o-ring): 1.80mm (1.8mm)
D-Tek 1/4" BSPP fitting: 2.02mm (2mm)
Swiftech Nylon 1/4" NPSM fitting (Eldon James): 2.59mm (2.6mm)
EK 1/4" BSPP plug: 2.01mm (2mm)
EK thread spacer: 1.53mm (1.5mm)
So, how's that Scott? ;)
BTW, Brian offered to lend me his Sper manometer for pressure drop testing and I think that I'm either gonna take him up on that or buy my own, as I'm realizing that I don't have the precision needed for the FuZion in the lower flowrate range (talking <= 0.1psig @ 0.5GPM).
LOL,LOL To :banana::banana::banana::banana:in funny man!Quote:

looks like dd high flow (current) might be nice, either that or EK thread spacer, just a little bow
also i hope that the guys designing these waterblocks are using calculus to find max surface area dimensions... i know its the best way if you factor in the rate that heat from the cpu reaches different heights on the copper pins, double limit is bound to have an intersection that is ideal. maybe ill look into water block design for a science intensive study/project for the summer :)
There's a problem, you can't calculate exactly how the turbulence in the block is going to affect the performance...now there's patterns of pins that are effective, but I can imagine that its not possible to calculate exactly what pin shape and exactly what pattern will get you the best results...sure you can calculate the ideal height for the pins on a block like the fuzion but getting a pattern/design is the main issue...Quote:

I ask olny because I already have a GTX, it looks great but I really dont want to bow it. I have remounted several times but on average my idle temps were 41c, load is 52c with an ambient of 22c. My e6700 is running at 3.6ghz with 1.49 vCore. I have seen may people post temps lower with the fuzion while using MORE vCore. I'm currently getting the same temps with the GTX as I was with my orginal Apogee :confused: .Quote:

On a side note, dont my temps seem a little off though ?
damn it stop saying thatQuote:

Gabe said dual cores ~2C difference which is not that great....i don't have quads so it is worth messing with it
this is true, there are many variables to consider, but it seems it could be done, i definitely know most of the calculus and the physics (calc. 2 and Harvard extension physics exp.)Quote:

once you know the ideal surface area, pin height, and density you would have to consider the arrangement of pins very carefully. From my initial thoughts it seems that the pin design on the apogee is most apt for surface area. The d-tek has cylindrical pins which is not ideal, it does however compliment the high flow nature of the Fuzion.
It will definitely be interesting to explore the in-depth physics behind these blocks
Well the Apogee are great blocks, but testing proves the Fuzion is better if the apogees arent bowed. I for sure would not feel comfortable doing it.Quote:

Anyways, pin shape and arrangement are a BIG thing...
ahhhh but did THEY have computers, i think not. ;)Quote:
