MCW462-UH inlet modifications

pHaestus · 01-28-2003, 10:35 PM

Noticed the MCW462-UH block on my desk today, and thought about Bill's tests with a swagelock fitting. Making a nozzle on this block improves performance markedly, as shown here:

I have no Swagelock fittings, so I decided to see what I could come up with using parts around the house. Here is what the Swiftech block's inlet looked like before any alterations:

I used a 5/8" ID barb with 1/2" NPT threads for the connector to the hoses. I first took a piece of 1/2" ID thickwall silicone and cut it to the size of the empty threads in the inlet:

Basically we are at the 1/2" copper pipe point on Bill's graph now. Not the best place to be. So I took the original 1/2" hosebarb that came with the block and cut the end off the barb:

I sanded it down to a smoother finish and did all I could to get it round again. I then stuffed the barb into the silicone tubing to make a (roughly) 3/8" ID nozzle on the inlet:

I haven't tested it yet, but I think it should work reasonably well.

hmm.... its odd that you call your watercooling stuff things that are just lying around the house.. I Think for most its like stuff lying around in a room at MOST

I wouldn't be so sure...

I had an even easier to do idea:

That's just some 3/8" ID hose. I am not as confident about the stability of this one though....

If those are nylon barbs, you could fill them with Devcon's Plastic Welder, then drill the opening that you want. It would allow you to experiment easily with different size nozzles.

In the Atlantis review BillA found the Atlantis to be very low restriction to flow, much like the swifty.

It would be very interesting to hear from someone who has a Atlantis as to the results of a impingement of the inlet in the Atlantes block.

THERE you go !
but be careful of the inlet fitting, it is delicate

I believe Jess is looking into this also
