May try those out if I break enough endmills, but only have 1 more year left at this base before I transfer out and become mill-less. And no updates on my waterblock except new sketch-up designs, since I have been stuck doing patrols outta remote islands and then came home only to be sent out to schools on the mainland. I think next week I will actually get a good stretch of time where I get to stay in one spot lol

It reminds me of being a deckie on the boat and starting out each day by shinning all the brass and we had alot....all the capstans were brass, the bells, most of the controls and more and then add in the barent seas to oxidize it while we are shinning it. Almost wish we had brass on C-130's so I could yell at all the new guys to go shine the brass till it's like a mirror!! For my computer, I am shinning the brass and copper once and then sparying it with some clear coat.

Ok, just read all 585 posts created by you blockheads! My eyes are bugged out, and I'm itching to get my hands dirty. There are some seriously skilled shopsmiths round here.

I'm gonna try signing up at a community college near me to see if I can get into a couple machine shop classes (and have access to the shop!)
Hopefully there won't be any issues with pre-reqs, and I may be able to get an email address there to sign up for a free/student edition of Inventor.

One thing I don't understand (among many) is the benefit of a triple (or more than 2) nipple setup. Anyone care to explain/link me somewhere?

Bowing to the Awesomeness,
MM

I think Cathar did it first with the Whitewater block, but it coulda been around well before then, I am not a historian on the subjuct but do know it's been around for a while. Whitewater was one of the first blocks to go with micro channels and was very restrictive. Intake in the middle pushing the water to either side lessened the restriction versus having the intake on one side and then forcing it to go through the whole channel.


Not sure where I got that pic from, but it illustrates what I am trying to say...although the channels are not really micro.


The new commercial blocks go mircro channels now, although instead of using two barbs to outlet the water from the block, they design it so that the water...once going through the micro channels just like Whitewater does...outputs freely on either side singularly and then exits via one barb.....like this


not sure which block that is, but I know my EK LT is similar to that and hear that the HK blocks are similar to the EK LT....and they all are pretty much Whitewater knockoffs with a twist.

Going three barbs was not really to increase flow....since after all it goes back to a single tube eventually (possibly if it exited to a res, it'd be useful). It was done simply because a micro channel was/is very restrictive and putting the inlet directly in the middle of the micro channel and having the water push out to either sides lessoned (halved?) the restricition and the two outlet barbs are just there to exit the water from either side since the blocks back then were not designed to outlet the water from the micro channels into a singular area.

That's my guess anyway.

I concur (what he said) and I think it's also about distributing the fluid more effectively across the surface.

I did it for two reasons
first my intended block at the time had two out lets
second I was looking to get some of the so call jet impregnation cool affect on my chip set and it worked, I am folding on my GPU while I type this and my temps are
CPU 47 MB 37 GPU 50 all in a single loop with only 1 of my 3 ultra kaze 3000 plugged in

Excellent explanation and pics, Herc! Thank you very much. +rep

I was confused about this statement: "outputs freely on either side singularly and then exits via one barb.....like this" UNTIL I really studied that pic which showed the channel on the top interior and just one hole. I see now. I like that design a lot! I'll have to look into this Cathar and Whitewater, I've seen that name a lot!

Note to self... look up "jet impregnation.
