Watercooling the GTX Poseidons!?

andlaw
Level 10
Hey guys, So I am looking for some advice/help with my current task in hand. I believe I am finally done with my current build, and am ready to make the leap from a closed loop water cooling to a full custom water loop! at the time I started this build, I was unsure of how many video cards I was going to get, and even which ones.. I have always been a fan of the Poseidon since the 780ti launch, and took the leap and now have 3 of the GTX 980's. I contacted swiftech about possibly just getting the new H220-X or H240-X with an additional pump, with an extra double and triple radiator. After my discussion with swiftech, I was told that there was no water blocks for the coolant to pass through from one video card to the other.. that I would have to run 6 seperate tubes, one for each.. is this true? or is there another method from connecting the video cards using fittings? or did I really just waste $1700 only to have to purchase actual water blocks? Thanks in advance, and if anyone has these cards can you share some pictures of your setup? I have been looking around the internet for images of them but cant find but a single card on water. thanks again for the time and any input will be much appreciated!

use angled fittings, and tube from fitting to fitting.
and i recommend 1 fan slot per non OC'd component, and 2 fan slots per OC'd component.
so if you going to OC and cool 3 cards + cpu i would recommend 2x 480 radiators and maby 60mm thick.
ive never used those cards ( poseidon cards ) so i cant say for shure how much cooling surface you need but its a rule of thumb i have so.

hmm that case. you can fit a 45mm rad down in bottom but only 3 fans on it since PSU comes in the way, a 240 ( 35-48mm ) front of PSU and a 360 - 480 60mm in top.

They have standard G1/4 inch threads so you can use any fitting you like and tubing to connect them. There is no special connector for them you will have to fashion your own along the lines kkn suggests.


Pic gives you an idea but your cards are closer together so you may have to angle things

While the swiftech h220 is customisable (I suspect they are trying to sell you one per GPU?) I would not bother myself...better to work out a loop for yourself with better radiator(s) and a pump good for high restriction like the MCP35X which you can find already combined with a reservoir...even in a bay reservoir for example...

I'm with kkn for three GPUs I'd say 2x240 or 1x 480.....for CPU as well 1x360 and 1x240 for example. Less will work but wont give you great temps as it becomes heat saturated on a long gaming session...

Thanks for the reply guys. I was thinking of the H220-X. which would be a double 120mm rad at the top, which i would use for the cpu.. then add a loop in for the GPU's with an extra pump, with a double and triple rad from either EK or alphacool and mount at the bottom of the case. that was one idea.. and then depending on how to connect the video cards, that was the deciding factor. If i can just do like you did, that would be cool...

my secondary, but more costly way was..

order a complete custom kit from EK. (2) triples, one for top and one for bottom, and a (1) double for the bottom. having the one triple at bottom doing intake, and the double right across from it there at the bottom using exhaust. then the triple at top would be set for exhaust as well. then the 3 fans in the front of the case would be just for regular air intake.. as well as the rear 140mm. but choosing which pump and so forth has yet been chosen. I would love to do a hardline, but figure for the first one I will just go with soft tubing. but when i chose this case, I chose an external dvd drive to keep the top clean and gutted for some spare space.. i would love to do a bay reservoir, move my HDD cage from the bottom right of the cage to right under where the optical bays are. throw in both the triple and double rads at bottom along with the pump.. and mount a triple or quad rad at top.. I want to keep my loop clean and simple. so i would more likely use more fittings to keep the angles so the tubing will be more or so straight... like a hardline would look. RED tubing, and distilled water to keep it simple. should flow with the theme of the build, which if your interested to see what I am working with, can be seen here: https://youtu.be/X66_qLfpaT4 (with the exception of only 2-way sli not all three cards in).


so with this all in mind. you would suggest the MCP35x.. and whats your take on EK vs Alphacool. and would you go for compression or the barbed fittings.. thanks again in advance!! ROG ftw!!!!

personaly i have compression fittings, i have barbed on my motherboard NB and i had a leakage there cause the tubing was coming loose.
so i dropped that part.
i would say compression is a safer way to go, just add a wee bit of vaseline on the OUTSIDE of the tube, that way it will be easyer to open them when you are going to change coolant ( once a year if mixed and every so often whit distilled water )
personaly i would drop the pump you have now and just go 1 loop.

i have a 480 bottom witch is 50mm and a 240 witch is 45mm ( if i dont remember mutch wrong ) and a 360 witch is 60mm in topp.
i recommend a tube res, you can get a pump connected to it so its not a stand alone res and pump witch i have.

heres a few examples of pump/res combos i recommend:

http://www.frozencpu.com/products/16994/ex-res-422/AquaComputer_Pump_Adapter_w_Aqualis_Reservoir_and...
http://www.frozencpu.com/products/23124/ex-pmp-298/Alphacool_Lighttower_All-in-One_Reservoir_Pump_Co...

and then you have the expensive option whit a high preshure pump witch you can controll:
http://www.frozencpu.com/products/25582/ex-pmp-335/AquaComputer_Aquainlet_XT_for_Aquastream_Eheim_Pu...

if you are going D5 pump i would recommend this one -> http://www.frozencpu.com/products/17488/ex-pmp-211/Aquacomputer_D5_Pump_Motor_w_USB_and_Aquabus_Inte...
you can controll it by USB interface and it have fan controll on it ( MAX 1 AMP!!!!!!!!!!!!! ).
and i would recommend a fan controller on the rest of the fans, mabye one you can controll by software mabye?

or an LCD whit temp sensors you can hook up to the water, like this one.
http://www.frozencpu.com/products/13163/ex-tub-891/Phobya_G14_Inline_Temp_Sensor_Coupler_-_2-Pin_711...

and you have to think about a way where you can add a drain point ( lowest point in loop ).
here i have quick disconnects witch i can just drain every thing from, between pump and first rad.

you REALY have to think tru it all before you start buying WC components.
sit down, mesure up things, plan it out, loop and where to place things, clearance to things+++++++
go over and list up parts you need and see how mutch it will cost you, always add on some extra monney ( trust me on this ), add some extra meters of tubing in case of miss calculated meshurements when cutting ( been there done that ).

LOL...too true

Can't say better than what kkn has put up there...

Pump choice?...D5 is a good pump too... just for 3 Poseidons in series maybe the restriction would favour the MCP...

I have a couple of D5s myself (for redundancy) since my loop is parallel, high flow GPU blocks and "fat tubing"...D5s like unrestricted flow
Not my pic up there by the way just pulled example off the net.

I have alphacool rads now and love them...better than my EK radiators but EK have a new line which I have not tried...

Nice rig by the way!

Hey guys, So I finally received a reply back from EK. here is the information that was given.. which is another option, definitely a more expensive way.. but again, money really isn't an issue, I want this thing to be done and done right 🙂

First off, I would like to determine, if these are your GPUs?
http://configurator.ekwb.com/step1_complist?gpu_gpus=1577
If they are, you can see all the compatible waterblocks with them here.

If you want to have multiple radiators in your case(and you need at least two to watercool CPU and 3 GPUs), I think you should go with this KIT.
https://shop.ekwb.com/ek-kit-d360-x2-caselabs-mercury-s8-drop-in
It has 2 radiators and everything you need to setup your watercooling system. It also have a very nice reservoir/pump combo which eliminates the question of where to put the pump.
You only need to add water blocks for the GPUs, 2 fittings and a Terminal to interconnect the GPUs.

GPU Blocks – 3X
If you have the GPUs in that link, than you need three of these.
https://shop.ekwb.com/ek-fc980-gtx-strix-acetal-nickel

Fittings - 2X
https://shop.ekwb.com/ek-acf-fitting-10-16mm-nickel

Terminal
Which one you need depends on the slots you are using for your GPUs.
If you are using these slots, than you need this terminal - https://shop.ekwb.com/ek-fc-terminal-triple-serial-csq



so for you guys taking the time to reply, VERY much appreciated btw.. what would you guys do? would you grab the kit, and just do a setup like the above posted pic.. or go full out and order the water blocks and go about it that way. so in the kit, it comes with (2) triple rads.. i have already opened up my case and moved my HDD cage from the bottom right to the top underneath the optical drive bay. so now I have LOTS of space in the bottom, easily able to fit the Triple rad. and mounting the other at the TOP of the case. these are the new model they offer, i guess they are supposed to be pretty good considering the review i seen. not sure of the pump/res combo.. but I am assuming since its apart of one the most expensive kits they have it must be decent... and IMO cant go wrong since it's only one, not two things to mount. so what do you guys think I should do here? save the money on the water blocks and use these like the diagram above, or take the full leap and do it all. looking forward to hearing back 🙂 thanks again for your input~

well they do not have enny stock of the "large" kit they posted to you.

if you go waterblock on your VGA's you will void warranty in case you get enny leakage or break them under the block applying. ( just to have stated it ).

like i posted before, sit down, pick out parts and see how mutch it will cost you.
think over what parts you will need.

so that way you will come up whit a estimate price on it all of what you can look forward to spending on it ( always expect to spend more ).

well, if you don't have particular budget problems...

Personally I would buy blocks for the cards...for various reasons.

a) The cooling channel in the Poseidon is Aluminium, if I'm not mistaken, and mixing metals in a watercooling loop can lead to galvanic corrosion...not sure how big a problem that would be in the expected lifetime of the GPU but still...prefer without. So, would prefer to see copper throughout the loop... rads and blocks.
b) the cooling from a dedicated block will be better
c) you could then use a parallel bridge for the blocks which would keep your flow in the loop higher and favour a D5 which is a great pump and for which you could find good pump/res combos as kkn has pointed out. Higher flow means better cooling.

I would not buy a kit....you can buy the pieces separately and get the tube colour you want...get the compression fittings (colours here too) you want (definitely want compression fittings not barbs...cleaner look less likelihood of things going wrong). I'd go for 1/2" 3/4" tubing and fittings. I'd also try to get a pump res combo with as large a reservoir as I could fit/get...makes filling loop much easier and safer for the pump when filling. I would stay away from anything other than distilled/deionized water and simply change the water every 3-4 months. I have never had a problem doing this.

thanks again you two! it looks as if I will be going with the blocks. I was just aiming towards a Kit because it already has everything included. but now that I know what I will be doing.. it shouldn't be too hard to get everything narrowed down. so I will list off the components I am looking at, along with a diagram of what I think my loop will look like, and I would much appreciate if you guys could give me some feedback on that that would be awesome!

I will be using fittings to make up for not doing hardline. I know it will be a bit more costly using more fittings, but I am going for a clean finish here.. right now I am rather stumped on my loop, I have come up with multiple ways, but would really like to hear from you guys on suggestions. I have attached a diagram of what the setup will be inside of the case., its a PNG to edit and re-post. Until I get this plotted out, I am unsure of what and how many fittings I will exactly be needing. I did choose the 1/2" 3/4" tubing. I know I will be needing to add in a drain port too, i figured I would add this in under the pump, in the line between pump to bottom rad. Thanks again for all your help! looking forward to hearing back as always.
