Watercooling for two GPUs - Page 3

post #21 of 29
As far as I know, it's the same theory as a rad. The path is linear- there is but a single path for the water to take, making one an in-, and one an out-port, and that's it.

Here's a picture of one of the "see through" GPU Full Cover blocks. The water goes in one side- and out the other, and can't do anything else.



[EDIT] After grabbing a tea, I just realised your point. Though I'm pretty sure the loss is negligible. You could do a funky scattered build, but I personally didn't want too, due to having to pull a 180 deg back up into my case.

personally i would say a 360 would be good for a quieter set up but a black ice 240 would also be up for it imo but you need high speed fans and would be really noisy.

The way I understand it there are two separate ways for the water, first GPU block and the second GPU block. After the water has went through these both there's once again only one way, the tube. But once again thank you all for your input. Learned a lot here tonight I think I will be ordering some WC parts after I've started the wooden case project first, might be a while though.

And this is the final cart I think I'll be going with. Any changes for the cart? Please, tell me

PS. That's two meters of the tubing, ~6,5 feet. I think it will be more than enough for one setup.

Edit: bobfig, I already decided to go with a 360 rad

Yup, looks good- Though you don't need the two Enzotech screw-in seal plug, as both full cover blocks come with a pair- You'll have 2 left over! (they're shiny... and mostly useless!)

You'll want to look into a Biocide (like PT Nuke), and / or Silver kill coil. That with distilled water and you're good to go!

I understand I need something like this and some distilled water but what are the coils for?

You don't quite need that... That's doesn't look like an additive, it looks like it's a water replacement. All you need is a Silver kill coil (A physical biocide basically) and / or some Biocide + anti-oxidant. Something like this. I looked on the Aquatuneing Finland site, but couldn't find anything similar (Though I'm sure translations didn't help).

I'm quite lost with this stuff really but I think that stuff I linked is just the biocide you were talking about.

"It reliably protects watercooling systems from corrosion and biological contamination."

"The recommended mixing ratio is 1:3 (1000ml concentrate with 3000ml distilled water)"

Straight quotes. I don't know for sure what you mean by biocide but I think that stuff should kill bacteria and stuff. Correct me if I'm wrong. Also there's a "english" link at the right top corner of the webpage. I think it's actually a german site even though it says "Aquatuning Finland". Most of the stuff is in german so I don't understand it anymore than you do (in case you don't understand german either of course, lol). But I'm off to bed. Might search for alternative shops tomorrow. Been a long night

lol, yup, then that stuff sounds good. I'm using Chrome, so everything is auto-translated to english

Biocide is simply something that'll kill Bacteria and algae in your loop- and in some cases, also protect any metal parts from oxidizing (rusting).

The more fans you have, and the more r ad area you have, the more quiet your rig is going to be.

Let's say you need 200CFM of air to ool those two GPU's (just an example here).
If you have to move 200 CFM of air through one fan, it;s going to sound like an airliner taking off. But if you have that same 200 CFM spread over 8 fans, it's going to be a lot quieter.

The more fans and rads, the less your fans have to spin to cool yur rig, hence the less noise will result.
