Hello all :)

So I want to get into watercooling so I can have a quiet and cool system. I had a custom setup many many many years ago so any knowledge I had then [probably old and wrong anyway] I have forgotten to be honest.

I have read through the guides and watched several videos about my options with my case. I put together a shopping list but part of me thinks I am overspending for what I want to achieve. I am also aware that my components are not the newest but still pretty decent?

My Goals:
#1 - Quiet and Cool system.
#2 - Has to be tidy and functional even though I havent got a window on the side of the case
#3 - Good value but I am willing to spend if it makes a difference.
#4 - easy to maintain i.e. flush out every 6 months?
#5 - Dont mix materials. Try to keep everything copper? Is that the best way to go?
#6 - Cool both 7950s with water. I am thinking this is pointless even though I do game but having a high stressful job in IT and a kid my time does get limited so spending 300+ on a new gfx card seems a little bit wasteful.
#7 - Have fun doing this mini project, learn something.

Disclaimers:
- I am getting a bit confused with fittings/stop valves/plugs how many I need of eac etc...Probably just need to read more but there are so many options its confusing.

Spec and questions:
XSPC X2O 750 Dual Bayres/Pump (Black) V41 - £59.98*
?? Will the pump be quiet and powerful enough for two rads? For the CM690 II case it is recommended to get a 60mm rad and just have a pull setup rather than a 30mm in a push/pull due to space issues.

XSPC EX240 Crossflow Radiator £41.99*
??Will go in the top of the case. May need a thinner rad if possible due to space?

XSPC RX240 Dual Fan Radiator V3 - £59.99*
?? Recommended for the bottom of the case to due space issues.

3x Primochill Primoflex Advanced Tubing 16/11 - Clear - £23.96*

10x Bitspower Premium G1/4" Black Matte High Flow 7/16" ID (5/8" OD) Compression Fitting - £69.80*
?? Is this the right amount for CPU block, two rads, two graphics cards, res??

1x XSPC RayStorm Pro WaterBlock - £64.99
?? Worth spending the extra on this? I doubt I will get much more speed from my existing 4.6ghz clock?

Mayhems Ultra Pure H2O 5Ltr - £12.95*

Bitspower Mini-Valve - Matt Black £16.98*
?? Required for future maintenance when draining the system?

XSPC Hose Cutter (0-25mm) - £6.95*
2x XSPC 240mm Radiator Gasket - £5.98*
??Are these a gimmick?

Other Questions:
I am sure I will need some 90 and 45 degree bends, not sure which ones? Also Is there anything I can save some cash on, better alternatives.

Finally Merry Christmas and Happy New Year to all. I appreciate your help and will post pictures when I get the chance :)


UPDATE 01/01/2015:

Right so my current list is this - taking on board everyones suggestions

My basket at Overclockers UK:

Total: £345.05
(includes shipping: £11.10)



THE PLAN
Top Rad
Mount top Radiator EX240 with inlet and outlet on the same side as the Reservoir for shorter and neater run. The rad will have two 90 degree fittings.

Fans will be located outside the case within the top cover of the CM690. These will be my existing AK-FN059 120mm Ultra Quiet Venom Viper in a pull configuration.

Bottom Rad
Fans will be mounted in a push configuration [same fans as top rad). Rad will sit on top and have 90 degree fittings as it will be really tight [apparently millimeters of room from the front fan]. The outlet of the rad will then go into the 4 Way Fitting whereby my drainage valve will go etc..

Routing Plan
Routing will essential going

Res / Pump > Top Rad > CPU Block > GPU Blocks > Lower Rad > Res > Pump

More Questions
1) What will I lose by not having an RX240 [60mm] rad and only a EK240 [30mm] rad. Is the 60mm overkill or its better to have it than not.
2) Can one 60mm Rad be enough for everything?
3) I made some minor tweaks to what MrMD suggested, this current shopping list should work?
4) EK Water Blocks EK-Thermosphere - Nickel - will these definitely fit the 6950s?

All sound good? :)

Never used a bay res or this particular model. However, I can only feel that a bay res mounted pump is going to be hard to isolate/dampen and will be nosier than a separate pump in another suitable location.

II case it is recommended to get a 60mm rad and just have a pull setup rather than a 30mm in a push/pull due to space issues.

Don't do Push/Pull. Waste of time.

10x Bitspower Premium G1/4" Black Matte High Flow 7/16" ID (5/8" OD) Compression Fitting - £69.80*
?? Is this the right amount for CPU block, two rads, two graphics cards, res??

No. At minimum you need 12 fittings for the parts listed. You will want extras anyway. They are cheap enough that you should buy more, and a few 45 deg rotarys etc for places where tubing might kink. Consider using hard links or a bridgeport for the GPUs as connecting GPUs can be fiddly with flexible tubing.


Mayhems Ultra Pure H2O 5Ltr - £12.95*

Get a premix solution which contains inhibitors/biocides.

Bitspower Mini-Valve - Matt Black £16.98*
?? Required for future maintenance when draining the system?

Yes, a drain port is useful. Do not forget to add EXTRA FITTINGS to put it in.

XSPC Hose Cutter (0-25mm) - £6.95*

Up to you whether you use this or not. Decent scissors or a sharp knife do a decent enough job.

2x XSPC 240mm Radiator Gasket - £5.98*
??Are these a gimmick?

Never used them, cannot comment. I imagine it will largely depend on the fans you will use, whether they are designed for rad use and whether a standoff between fan/rad is worthwhile. Doubt they will represent any meaningful temp difference.

I am sure I will need some 90 and 45 degree bends, not sure which ones? Also Is there anything I can save some cash on, better alternatives.

Yup. 90degs are overkill in my opinion, never needed more than a 45 deg personally, depends on your loop plan.

Always best to avoid 90 degree bends if you can as each one in your loop will lower the flow rate and hence the cooling ability of your system.

I used radiator gaskets ion mine purely to reduce sound vibration between fans and rads.

Agreed. pull/push only worth it for high speed extreme cooling for record breaking attempts.

XSPC rads come with gaskets,no need to buy new extras ;)

If one of your primary goals is quietness you will want to avoid the lower end and bay mounted pumps.For silence you want to be looking at a D5 pump.

Its immposible to get new 7950 blocks now as the cards a old.You could get a pair of universal blocks like the EK-Thermosphere and use them,you would need to get the additional mounting plates and some heats sinks too tho.Alternately you could try and source some Full cover 7950 blocks 2nd hand,maybe try the MM?


Whats your budget?

Get more 90s than you think you'll need. My build got delayed because I failed to get enough. So long as you don't open any you don't use I'm sure the good folks at overclockers would rma them for you.

Ok so changing my list to:

XSPC RayStorm CPU WaterBlock (Intel) - £49.99
?? Its cheaper than the Pro version.

16 x EK Water Blocks EK-ACF Fitting 12/16mm - Black Nickel - £60.64*

2x EK Water Blocks EK-AF Angled 45° G1/4 Black Nickel - £4.99*

2x EK Water Blocks EK-AF Angled 90 Degrees G1 / 4 inch - Black nickel
?? I may need 90 degrees for the lower rad in the case as the inlet and outlet will be towards the fan side to due to the proximity of the PSU. £5.99*

1x EK Water Blocks EK-AF Ball Valve (10mm) G14 - Black Nickel - £12.95
?? Cheaper than the other valve I chose

EK Water Blocks EK-AF FillPort G1/4 - Black Nickel - £5.99*
?? Do I need this?

Mayhems Fine Silver Kill Coil - £4.50
?? I guess I can put this in resevoir and just use distilled water?

Guess the above is all good and compatible?

My total costs are:
Total order value
Total value excluding VAT
Total VAT at 20.00 %

£347.66


Seems quite expensive or is it about bang on? Looking at the OcUK kits, they are half the price which sort of confuses me as it suggest I am adding stuff I dont need or they are missing stuff?

I havent got a budget really but i am trying to be sensible and weigh the cost and how future proof it is for when I want to upgrade.

This pump better? D5 Dual Bay Reservoir/Pump Combo V2... CM690 II case may be limited in space for seperate pump somewhere?

I fully get your point with the 7950s...You think its even worth bothering with it?

Get more 90s than you think you'll need. My build got delayed because I failed to get enough. So long as you don't open any you don't use I'm sure the good folks at overclockers would rma them for you.
The 90s I got in previous post ok? I think I may need two for the bigger RAD at the bottom of the case.

Heres what you need would need including gpu blocks,based around a D5/bay combo :)

Only two things things missing are fans and the additional mounting plates for the gpu blocks.

My basket at Overclockers UK:

Total: £453.77
(includes shipping: £12.60)



Watercooling a pair of 7950 is probily still worth it if you plan on keeping them for a while,the reduction in noise would be significant IMO.


Edit:Regarding the ocuk kits,most of them use entry level parts and have the bare minimum required to build a loop,thus why they seem a lot cheaper than than some of the kit your looking at

Thank you very much for spending the time to do this.

What would I need the XSPC G1/4" 4 Way Fitting for? Also is 1m of tubing enough?

I should have put 2m of tubing actually,my bad.

The 4 way is for the drain port.You want this as low as possible in your loop for convience.In your case that would be the bottom mounted rad.

So you into one rad port it would be a standard commpresion fitting,in the other port it would be, Commpresion>4 way>male to male>Rad. Then put a stop plug on one of the open ports and the drain valve to the other(using another male to male extender)

Would look similar to this

my advice - don't buy new.

You can pickup most of the important (and expensive) components from the MM for half the cost if not better. There will obviously be some bits you will need new so dont discount purchasing from OCuk completely! lol :)

I would have to post another 250 times which isnt going to happen. I been purchasing from OcUK 16 years maybe, shame i cant get access to the MM.

Question would having one bigger radiator [RX240] that is 60mm instead of two rads, handle CPU and two GPUs?

My original thought was to have an EX240 and an RX240? Would I be better off with 2x EX240s? I am literally on the verge of ordering everything but trying to save a few pennies here and there if possible.
