Modding D-Tek Fuzion GFX for more flow/less restriction?

[Martinm210]

Just remember pressure drop is not a linear relationship to flow rate, so it's very possible to be several times less restrictive but only get double the flow rate

Yeah I understand, it was just an example

Here is pictures of my modification. This increased the flow 5X over stock performance. NOW it flows better than MCW60!

What sized holes are they?

If that's the only modification needed to be done, and it now has equal or better flow rate and/or pressure drop to an MCW60, then I might look into doing that for my loop, since www.flabbergast.com.au is offering package deals of a FuZion GPU + UniSink for AU$95, as opposed to the ~AU$120 for an MCW60 + MC8800 heatsinks, or ~AU$110 for MCW60 + UniSink.

so I went and took apart my block today, much to my disdain (ugh, those O-rings are so small, and the ridges are tiny) and I found out that instead of the block being 1/2" all the way though, turns out the jet in the middle is a 3/8 hole instead, and that is probably why it is so restrictive. so I can see why drilling holes would make it flow better

The CPU block is also 3/8" and flows just fine, I think most of it is the sharp extended entrance. The other thing I thought about was making some sort of doughnut shaped ring on the inlet side just to give the water a more radiused inlet. That's something you could try that would be completely reversible.

while the Fuzion CPU might be 3/8, it is also straight down into the 3/8 hole, whereas the GFX is not. I figure I will try and hook a hose straight into the fitting since I am running 3/8 and 1/2 split system (haven't made any barbs yet)
