Any news on the cascade xxx? - Page 14

Well here's what the final block will look like in basic Socket 462 (Socket A) format. There will be an aluminium universal adaptor plate that fits over the top for Sockets 423/478/603/604/754/775/939/940. Presently considering getting the plate anodised in black as well. Don't have an adapter plate in hand yet though.

Silver bases are definitely needed. Got to go all the way with the black/silver thing. Shiny plated adapters?

Etacovda · 08-31-2004, 10:44 PM

Chrome/Nickel barbs, SS screws, Silver base, and chromed, stylised chrome adapter plate

mmmmmmm sexy

Actually you're describing the silver/g5 now...

Yeah, its what im expecting it to look like

I apologize if this has already been explained earlier in the thread, but what does it take to get on the waiting list for one of these? I imagine that it is quite long already!

Thanks!!!

I think you don't have to do anything to wait... I too, am waiting.
Cathar said pre-order is not open just yet. We'll just have to wait.

at overclockers.com.au he said end of september and there would be enough for every one for the g4/copper

Quit teasing us please....

I posted this over at OCAU. Figured some of you guys might be interested:

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).

Gratuitous fountain shot. Fountain reaches around 3m into the air.

Good lord! That is one helluva pump! Nice, Its hard to imagine that in a computer. Nice jets!

Blackeagle · 09-04-2004, 09:14 PM

HEHE,

No wonder you can get AMD mobiles to 2850mhz. !

Looking forward to seeing it done and a full comparison vs Cascade or others. I hope you'll also send pH a production version Cathar.

Great work man!

saperboy · 09-04-2004, 09:17 PM

It certainly is awesome.

Maybe I can use this in my Mom's garden too

2850? I guess I didn't post anything here about it. Time to correct:

Room temperature water-cooling. Not benchmark stable though.

Pump is strong no doubt. Calculated jet nozzle velocity there is up around 10.0-10.5m/s based on the flow rate being seen in that test. Peak possible velocity with the MD-30RZ is around the 12.5m/s mark, but only through restricting volumetric flow rates to a mere trickle (~1LPM) with the restriction required to achieve that.

Still, even with an Eheim 1250 in a full assembled 1/2" system the Storm block's jet velocity is around the 5m/s mark, while with the Iwaki MD-30RZ on a Cascade the jet velocities were around the 6m/s mark.

It's not really possible for me to eke out significantly more velocity without choking flow rates to a near stand-still.

Nice pump and that is one hell of a o/c....

Sweet. What Vcore did you hit that speed at?

Vcore was at 2.15v

do you always run these kind of voltages ?
how long do your cpu live?

In ~5yrs of pumping high voltages through CPU's, I've never lost a CPU yet due to over-volting it.

IMO, 2.00v full-time is the limit of where I'd feel safe with putting through the AthlonXP's.
