Need Advice on Watercooling my System

[rakoja]

Hello there you experts 😉

I could need some experienced opinions for my next step with my PC: Watercooling.

At first I will be watercooling my GPU only, because my CPU has a very awesome looking and quite cooler (Be Quiet! Dark Rock 3, handles the CPU at 4,5GHz with low to middle speeds).

So, i guess it is okay to just show what i plan to get: https://www.caseking.de/cart_load/c2e4ec2516e8829d5e5c5b9164d01de5

I already own a Waterblock (EK Fullcover incl. Backplate for my GTX 780 Ti), so that's not necessary anymore.

Basically my Questions regarding this are the following: Will 1l of coolant liquid be enough? And Do you guess 1m of tubing is enough or am I right with going with 2m? Unfortunately I'm not equiped with tools for hardtubing, if someone has something like a good set for this, that would also be greatly appreciated, because this would mean some more experimenting for me, thats fine since I like more constructing the pc for make it look awesome than playing with it.

As you can see, I really have just a pump with an included res, some tubings, 6 1/4inches fittings, and a radiator. Do you think the 360mm one will do good work with a single 780 ti? I have 3 Be Quiet! Silent Wings 2 for this and iI don't want to run them on 100%. Do you think it is necessary to get some angled fittings? I'm not sure right now, but I dont want to break my work for some days just because I saved me 10$.


At this point I thank you very much for reading and for any help.

The 780 Ti OC'd pushes 300 watts ... you'll need 60% of that to be handled by the Rad (180 watts).

One of the better 45mm thick 360 rad will provide 183 watts of cooling with 3 fans at 1250 rpm.....a 420mm will do 250 watts. I used 2L in the build below..... (420 + 280 rads + 250 res) .... I think ya may be littl short w/ 1 L.

For rigid acrylic tubing, I'd recommend

Tube Mod Kit - 10mm / 12mm ID (EK-HD Tube D.I.Y. Kit 10&12mm) http://www.frozencpu.com/products/21263/ex-tub-2005/EK_Solid_Tube_Modification_Kit_-_10mm_12mm_ID_EK-HD_Tube_DIY_Kit_10and12mm.html?tl=c633s2057b133

Masking Tape - 2" x 180' Modding Masking Tape http://www.frozencpu.com/products/14493/too-40/2_x_180_Modding_Masking_Tape.html

I actually replaced that Debur tool with a metal one which worked better

I used a Delta scroll saw for the cutting tho .... it was here already. Yell if ya need help

I'd buy some extra tube and some fittings (Quick disconnects) for a drain tube ... and don't forget to include a fill port somewhere....top radiators with both top and bottom ports excel here. You can see my drain at the bottom right of bottom rad

Thank you for the advice with the thicker rad, I guess i will go with a EK-CoolStream RAD XTX 360 then. This also has a top-port which could used very well for filling I think. Didn't thought about that topic before, just "yeah just fill that loop in the reservoir", but now when looking at this a bit closer it wont make sense there, since some parts (top of the rad and maybe the waterblock) will be above the top of the res, so i think there could be some problems (liquids floating out after the water reaches the res again after the first loop).

These tool-sets look very good, I thought there is more that I need but maybe hard-tubing is really worth thinking about it seriously. Can you say something about how safety hardtubing is with the fittings and so on?

The building will approximatley start in mid-february, so there is some time for measurements until there. (thickness of the rad, i plan to add another one (2x140mm) on the top sometimes when including the CPU, don't want this to be blocked)


Thank you again for your help, other opinions are still always appreciated

Thickness doesn't matter all that much.... which goes way against what you would expect but facts are facts and test measurements don't lie.

Alphacool Model-thickness-rpm-watts of cooling

ST30 1250 181
XT45 1250 183
UT60 1250 188
Monsta 80 1250 197
At 1250 rpm, doubling the rad thickness from 30 to 60mm gets you a whopping 7 watts


ST30 1400 199
XT45 1400 204
UT60 1400 210
Monsta 80 1400 223

ST30 1800 242
XT45 1800 257
UT60 1800 269
Monsta 80 1800 281

Id use a 45mm thick 420 on top and 60mm what fits on bottom

I have been running a year (15 mos) with no mishaps.... nor have I heard of any
