the g5 water blocks jet pics!!!

[PHILIP1193]

ok here is some info i found on the block which im gunna hopefully own and im a bloody impressed by the pics, let them speak for them selves

Okay, I've decided to relent and post some piccies I snapped today of part of the block in action, being the jet acceleration stage of the block. I spent a lot of time tweaking and refining the block to get this level of pressure -> velocity transition taking place.

In general the jets are converting most centrifugal pumps' pressure into velocity to a point that is between 80-90% of the peak possible jet velocity achievable with that pump. Increasing restriction/velocity beyond the point I selected saw overall flow rates start to drop away very rapidly with very minimal gains in water velocity. As flow-rates drop, so does the thermal capacity of the water per unit time. Much juggling with calculated and predicted heat transfer co-efficients, pressure drops, pump PQ curves, and pressure-drop considerations of other components in a water-cooling loop, saw me settle on a point that I believe is as close to a one-size-fits-all balance point as is possible.

The jet intakes were carefully tweaked in a cost/machining effective fashion to provide a highly efficient level of pressure drop into the acceleration jets. In terms of flow rates with a given pump, and taking into account the rest of the block's resistance, it was calculated that perfect jet intakes would be unlikely to boost flow rates by more than a further 2-3%, so overall I was pretty happy with the compromise.

Okay, enough of the babble, here's the piccies:

For a frame of reference, the block is being held at a measured 1.5m above the ground, and where the water is hitting the ground is a measured 5.5-6.0m away. The pump being used was the Iwaki MD-30RZ (50Hz power).

How the f*ck ke keeps the water in that block and not blow the barbs off ill never know, but gee wiz for a block that is mighty impressive nozzles

more pics of teh inner workings of the block

Such a nice block that, very expensive though, but with an Iwaki pump there is no better watercooler.

Those pics are damn impressive, makes me wish i could afford one.

Looks very nice - but is that aluminium?

Aluminium hell no - its solid silver mate. (the base)

lol not to rub it in but i can , i cant wait to get it in an all running, thing is though i dont think many people really appreciate how RARE these are, he doesn't just make this randomly, these are all custom made i.e. made on request and because they are silver it will conduct better than copper and i if you own one oyu will be one of the few who own one in teh world, im not sure hwo many he has made but possibly 100?

loool. Yes I am an idiot

 

[Phil Stanbridge]

These *should* be in today!!!

These *should* be in today!!!

OMG!!! thank god i get cheque clears a 12am tonight , i am sooon getting one of these lol

Yeah i know how rare they are, only a few nutters in the world with the readies to match

LOL @ Aluminium! Very expensive aluminium!!!

What pump are you using with it?

You had better post pics!!!

I'm using the AQZ 50Z mate with mine, will be the best pump for the job. It loves the complexity of these blocks and should perform well with a HE120.3 rad.

 

[PHILIP1193]

Well when i do get it i using a lian d4 pump with polar flow housing @ 12v. I had my gpu first then the g5 or teh loops runs funny and tubing is every wher ebut when i tested the diff way round i only got a 1°c temp drop by going cpu > gpu not like it is now gpu to cpu! The block should get ample pressure and simple because its a silver block and uses jet technology it will yield results im hoping up to 5°c+ temp drops if not more!

And pics, you got em, put it this way if i order to moz it comes wed you got pics wednesday night! and ill even do temp comparisons!

Cant wait!

I would love to get hold of one of these blocks, but can't justify spending anymore after my Cascade SS

 

[PHILIP1193]

OMG!!!! just got my blockl and OMG!!! how nice is it, i cant belive hwo nice it is i cant work out hwo to install it and his web site is crap lol any advice phil or any 1 who owns a g4 ?
