Cascade 5 (2 Stage GPU)

[bazx]

as talked about earlier i will be trying out some water cooling on the first stage DSH coil

here is the cooler i will be trying out its a coolmaster all in one unit i used for cpu 2 years ago

i have made up a stand for it so it will sit above the cascade

Now that's a new twist,very interesting,can't wait to see it.

Now that's a new twist,very interesting,can't wait to see it.

you will see it thursday

just been running some tests with the water cooled DSH and i must say i am very surprised i ran the unit for 1 hour and

35c knocked off the temps from compressor to condenser

sorry about all the temp probs all over the images i was having a look at superheat as well

the white prob line is T1 going in the DSH and the yellow is T2 comming out

 

[bazx]

i moved on to the large water barrel

and a pond pump

more images here

[bazx]

the pump is the same unit people use in there garden

the idea here is to take the cooler water from the bottom of the tank

and return the warmer water from the dsh to the top of the tank

and as the water cools it drops to the bottom

this has worked so well i am going to stick with this for a while

in this image you can see the loaded temps/pressure of the first stage

13bar / -50

this is by far the strongest first stage i have ever built and to say i am happy with it

would be an understatement

(the load is coming from a X6800@4900mhz/1.8vcore 32m run (more of this later))

i was unhappy with the vapo type dsh on the second stage so hooked two fans up

to a larger unit

before i went ahead and made up the gpu line set i wanted to load test

the evap

evap used in this load test is one of little devils chilly clones

o/s is just my desktop vista

the cpu is a X6800 @ 4900mhz

m/b asus commando

vcore is 1.8v vmod and droop tested with meter

load is super Pi 32m

T1 is temp taken with the temp prob taped to the outside of the evap

T2 is temp taken with the temp prob taped to the suction return about 10 mm away from the evap

the shut off hand valves have work like a charm as well

i just close the liquid line with the unit running wait 1 min and close the suction return

turn off the unit and remove the line set with no charge lost

Started running some load tests with cascade 5 and a 8800GTX kindly lent by

Raja

Thanks man i owe ya one

In the tests i was only looking at load on the unit not bench results

The card was over clocked to 902 core @ 1.55v using riva

The cpu just ticking over @ 4.8

Load is future mark 3D03 which it completed fine

The cascade evap temp (measured 10mm from the evap on the suction return) did not move more then 1 deg during load and sat around -104/103

o/s vista but for the next set I will put xp on

here are 2x 15 sec movie clips

WOW Awesome work.

Wish I had one of them in my shed.

That clock its rather big aswell. :O

Somethings not right with the movies...FF opens up a load of code for me, but no movie.

Your rig is beautiful, and the temps are excellent!

 

[bazx]

hi kenny i just checked and it works for me can somone else check

http://www.net7.info/1/cascade5/working/movie/

there should be to clips in there

the temps are way to good tbh the frost is spreading 3 inch from the core

the gtx just ant got the power to over come the unit

i might need to put some shims in

First one works fine. Second one I get nothing from though using WP11.:?

 

[K404]

I tried in IE *shudder* works fine...sorry!

 

[Thickbrit]

Wtf,did you guys not hear the man,he said he has designed a removable/interchangable lineset with no loss of charge.Simply brilliant and brilliantly simple,outstanding work Bazx.Shame about it being too cold though,i actually always said a s/s was enough for gpu,at least for me anyway.

 

[K404]

is the lineset the neck/evap section?

 

[sacha35]

Truly outstanding mate, you have set the bench for us all to dream about with this setup.

well done baz seeing is beliving and i have seen this and it truly is an amasing bit of Kit.
