Water Cooling Tips Advice

Aussiemat · Jan 1, 2012

Hi Guys i am planning on doing this to my system and was wondering if anyone can see any probs or has any tips for me this is my first water cooled build and although i have done extensive research on the subject its not hard to miss something easy

I removed old pics

You have twoi reservoirs, also you should just run the CPU and GPU in series, the CPU gets more flow that way and it should help keep it cooler. Otherwise it looks like a pretty decent setup. GL.

i have the 2 reservoirs because i will be mounting the rads on top of the case and the top reservoir should make it easy to fill, shouldnt be too much of a prob to just bleed the air out of bottom tank

375 l/hr wont be enough flow?

If your pump is rated at 375 L/hr and you have a parallel loop then you need to halve that value, assuming equal restriction through each loop (which is extremely unlikely). So really, in a loop with equal restrition on each side, you would have 187.5 L/hr, or 49.5 Gal/hr, or 0.825 Gal/min. If I remember correctly, we usually shoot for around 1-1.1 Gal/min (someone please correct me if I'm wrong) so you are close, and your temps will be fine, but you'll have better temps with a series loop. ESPECIALLY since this is a completely theoretical situation assume equal restriction. If your CPU block has higher restriction then even less flow will go through since the water will take the path of least resistance.

Also, with restriction in the loop you probably won't see the full 375 L/hr flow through the loop, so the value drops even more. Just a few things to consider and pretty much the main reason most people here will recommend a series loop over parallel. I think Skinnee also tested this and found series loops provided lower temps. Again, someone correct me if I'm wrong, but I'm pretty sure it was Skinnee.

Not the best pumps...and the parallel thing is a no-go. Also, I'm not sure I understand how having 2 reses is gonna help, you know that you're not supposed to run WC pumps dry ever, right? As in it takes just a few seconds running dry to destroy the bearing in them.

ssjwizard · Jan 1, 2012

@ jezus that was pumps in series/parallel not water blocks.

Parallel bits can work but the priority is on cooling the CPU as it has the highest heat density. You want the absolute maximum amount of flow over your CPU.

That may not be the greatest pump but it does its job fairly well. I have the X20 750 in my wifes fusion setup running series with 2 RS 240s CPU and GPU blocks.

pump is rated to 750 i allready halved it which assuming equal restriction which i do plan on managing would be about 1.65 Gal/min

i am planning on upgrading the pump in the near future this is also way i am starting with a parralell config as i plan on running 2 pumps in the sytem prob rated at about 800 to 900 l/hr each and adding a ram cooler after the cpu then the north and south bridge and voltage reg after the GPU

Understood but i am thinking if i undo the bottom tank bleed valve the syphon effect should fill the bottom tank from the top tank then it should never empty unless changing water,top tank lvl fall below output pipe coming from bottom of top tank or catastrophic failure! also gives more room for bubble removal (i am sure there would be a tech term but hey its early) and also more room for expansion/contraction if i decide to go CRAZY with my overclock

Don't do parallel flow without identical blocks (dual, matched cpu blocks, dual/triple matched gpu blocks, etc), you end up having uneven flow.

ok what about if i use 2 independent cooling loops 1 loop cools CPU then Ram
2nd loop cools GPU North and South bridge and voltage reg i'll plan it out and post it

You can do 2 loops, but they need to be 100% separate, as in there's no way water from one could get into the other.

so something like this then ?

it was going to be a $800 ish build anyways may as well just budget any extra $300 and do it right the first time....

i might add my ambient temp is around 30 degrees celsuis and about 70 to 99% humidity for 3 to 4 months a yr here which is why i am wanting to go a little bigger rather than conservative for this build!

m0r7if3r · Jan 1, 2012

Yea, looks ok, couple things though, southbridge is on the CPU now, so there's nothing to cool down there, you might be able to find a full cover board block and cut the chipset to one block (I think fc board blocks look pretty slick personally). You may wanna put the chipset with the ram and cpu, GPU may end up heating it, depending on how the raddage works out (just a consideration, probably a nonissue). Other than that, I don't really see any issues...though, given, we haven't actually seen a parts list

Antec? (from memory) 750 80 Bronze tru power
GV-N580UD-3GL
250 Gb SSD
1Tb Seagate SATA 3
Win 7 64 Bit Pro will be the OS

that was just a touch over 2 k AUS

the WC Parts List which is getting Scaryier by the minute is allready just a touch over 1 k but other than the blocks i think this Set-Up should last me 5 yrs or more!
ok here goes

2x Swifttech MCP6555-B 12v Water Pump 317 Gal/Hr
Raystorm Cpu Waterblock
Razor GTX 580 (Still Haven't fully looked into if it fits my GPU but looks good so far)

Rad Brackets
2x T adapaters
arctiClean 1&2
3 Pin to 9x3Pin y Cable

Mod Right Cable Right Single Braid Dual Power Supply(Could of made my own but it would take hrs to make it look as good as this one)
2x Alpha Cool Cape Cope Coolplex Pro 25LT- 250mm
2x Liquid Cooling G 1/4 Inline Flow Indicator/Filter
2x FrozenCPU.com Custom Thermal-Star/Bitspower liquid cooling temp Probe
i have seen a bracket for the temp probe display for dual displays but thats where i was at when i checked back in here
almost forgot the generic 350 Watt PSU for running the 6 Fans for Rads, Pumps, and as many case fans in the df-85 i can
i also am yet to work out exactly how many 90 degree and straight compression fittings i have to order but its going to be ALOT

Anything Expensive i have missed before i fill out my budget with MISC ?

Ohh Can I mention so far EVERYTHING on that list is from FrozenCPU.com

I'm a bit tired right now, so don't take this as any sort of guarantee, but it looks pretty good.

Any reason you went with the 655 over a DDC variant? Also, you're aware that the flow and temp sensors are not going to be very accurate (it's just the nature of them), correct?

Also, be very (VERY) careful with the blocks on those cards, one cap too high or a 2cm shift in the position of the GPU or one mounting hole moved even 2mm and you've just thrown a few hundred bucks away. Keep in mind, with that, that there is always the option of universal GPU blocks, though they are significantly less blingy.

Thank you this has been about a month in planning and i am looking foward to getting all my bits and pieces and making a vid of the assembly

m0r7if3r said:

the dual 6555's were always going to pump my system one day mainly due to $ to gal/min comparison, also the way they mount and the mounting bracket influenced heavily

http://www.frozencpu.com/products/1...spower_Liquid_Cooling_Temp_Probe_Display.html +-1 degree is close enough for me. Flow sensors are just a spinning wheel to tell me they are definitely flowing also filtering the coolant before it goes to my blocks sounded like a good idea

Yeah this is why i am holding off on getting any of that stuff so i can confirm with s/n 's that they will definitely fit my products

Aussiemat · Jan 2, 2012

just had a thought AFTER i posted (DUH)

i will have to put some positive pressure into the breather loop when the res tank empties until the rad inlets tubes empty

also i will have to either think about tapping a breather directly into the top of the rads OR another T and Tap at the very top of my inlet pipe to my rad otherwise they will be a pain in the *** to bleed

Aussiemat · Jan 3, 2012

Well it would seem with all of the extreme's in weather the WORLD has been experiencing it might take another 2 or 3 weeks to get my base computer (HDD's Are hard to source)

. BUT it does give me somewhat of an opportunity to change any parts, any ideas or leave it as is?

m0r7if3r · Jan 3, 2012

Yea, couple things, plastic fittings suck, don't get the plastic T, go with a bitspower/enzotech metal 3 way g1/4 fitting, should help your flow out and it's just better built.

Ram: Have you looked at MIPS stuff? I think it's purdier (personal opinion...it's also the only single stick ram coolers I'd ever recommend to anyone)

Other than that...not much to say, looks like you did your research

ssjwizard · Jan 3, 2012

Do you have a link for this "MIPS stuff" you refer to. I was(am) looking at ram cooling for my FX rig and the koolance coolers were about the only good ones I saw.
