Went through this thread again from start looking at the pictures only... what a joy and learnful!
Again, thanx for sharing!
Will you do some sleeving? White might suit this build well

[smicha]

Thank you guys.


As for sleeving - I will (or get Bitfenix extenders, same I got for 2xZs for Piotrek). Enermax PSUs have terrible cables even for custom wiring. http://mainframecustom.com/ emailed me that redoing all wirings for Enermax PSU may cost more than PSU itself. So I think that 8 and 6 pin extender from Bitfenix is a great solution and HQ. I bought a crimper already and in future I'll do all custom wiring. There are great companies that sell wires, sleeving,... http://en.mdpc-x.com/mdpc-sleeve.htm.

EK-FC Terminal TRIPLE Parallel

....

Hey Smicha,

This thread is a big value for information and inspiration!

I was looking at this beauty photo,
And since that I am learning about wc since recently ...
I wondered if there is any quality difference for triple bridge in CSQ Plexi or black POM Acetal ?

Parallel is better then serial? ... coz' the liquid does not go from card to card to card, but with three seperate ways, and therefor the incoming liquid has same temp for all cards. Right?
I guess this has benefit in the beginning of flow starting, because I have read that after a half an hour or so, the temps in the whole loop will be about the same, right?
Is there a benefit for serial bridge? Is the flow not better with serial compared to parallel, because it does not split threeway?
If true... Why have you chosen for parallel over serial?

Greetz,

1. If flow is good parallel gives better temps over all cards - go with it provided flow is good, loop is well designed.

2. For your Bitspower waterblocks for Z you cannot go with EK bridges - use BP acrylic links (go parallel).

OK, thanx...
What a tempsYou got there!

[smicha]

These temps were actually over constant 3d modelling in modo and rendering as preview (up to 100 samples).

But at Idle and without Octane usage temps are lower and fans are set to possible minimal speed.

Hi guys,

i can confirm, that serial loop for triple or quad GPU connection is not good... go for parallel. I also thought of the water flow, but it seems to be better to have less flowing water through all GPUs at the same time, than having faster flowing water going through one card by another... the last card definetly will always be the hottest. I got temp differences of +15 degree for the last card.

Cya,
ChrisVis

My old Phobya 560 died and is replaced by Black Ice SR1. The rad is 9 FPI which makes it silent with NB PL2. The side for push has greater distance to fins, which makes it quieter. The only drawback are 4mm diameter screws (3mm are standard), and there are only 16 longer of them (shall be 32 for push-pull: 16 - 30mm, 16 - 35mm). I could not use great noiseblocker screws - had to buy 16x 35mm long ones (4mm diam.) My general impression is that SR1 is a very good rad (with about 2350W-2500W capacity), decently priced (I paid 90EUR, bargain, 130EUR regular) but requires huge case, caselabs SMH10, STH10. (I still value airplex as the best on the market, although with heavy a price tag).

Temps under OC to 1250mhz on core and 7000 memory are 45C at 800-900RPM of NB PL2. BTW the single 480 airplex radiator managed to cool 4 gpus to about 52C (not OC), but fans were set to their full speed (1400RPM). With the 560 rad temps are about 10C lower and fans are spinning 40% slower (silence).

Only one word : beautifull !
My rig is like garage mess compared to yours !
