Looking to water cool my whole unit very soon and just wondering what block i can get that will 100% fit my XFX 6950 2gb cddc card. I would rather have a full cover rather than a single block but im aware that if i just go for the simple option and get a single block like one of these:

I will have problems when im using x2 90 degree angle fittings to get the pipes facing the right way.
Just wondering if anyone has seen any good solotions or has any opinions or advice for me
Thanks

This is kind of what im thinking something along the lines of this, Someone please let me know if you think this will work.

I've got the aqua computer type II block fitted to my HD6950. This is what my version 2 card looks like.


Block looks like this when fitted.


OCUK do seem to be out of stock of the aqua computer block though. you will need some G1/4" spacers (male-female) to space your angle fittings away from the generic gpu block. (like this)

i ran the exact same setup that you intend to run and can say that it will work, but you won't get brilliant temperatures with it. you will need a second radiator somewhere, ideally another 240mm.

i went from this...


up to this, which has finally given me some half decent temperatures.

No its not a reference card ( shame got 2 blocks lol ) . I would go for gpu only then if / when you update you can swap over. You should be ok with 90's, what problem do you think you would have ?
 
Hmm thinking about it it wont be too hard, im just a little worried as i've never water cooled a system before haha. Can't be too hard.

What block do you recommend?
Any tips from personal experience that would benefit me?
What's the best way to drain a system once filled?
Is a watercooled pc ok to move around a lot, like take to lan?

You can still get full cover blocks if you shop around. A generic gpu block has one single advantage, that allows you to keep using it on your future graphics cards provided the mounting system doesn't change significantly. The problem is that you get no cooling for the VRM's or memory and you have to cool them passively with heatsinks.

Draining can be done by one of the following:
1. having enough give in the hoses to allow you to tip the reservoir into a bucket and either detach a hose or pour out of the fill port.
2. having a drain point in the case.
3. detach all the blocks and remove the loop then drain in the sink. (This method risks damage to the block faces though and a bay res has to come out of the case via the front)

I've not had any trouble since filling my system with moving it around. I had to move it and bash it about a lot during the bleeding process which was probably the ultimate test for leaks. I'd obviously give it a once over before moving it to ensure all the fittings were tight and the hoses were firmly attached. I'd also minimise the number of rotary angle fittings and use clamps on the fittings just to be sure. I used PTFE tape on all of the threads as an extra precaution to seal the threads. (it's an active barrier that should reduce the need for the rubber O rings to be perfect) I chose to use 1/2" barbs rather than compression fittings as i prefer to be able to tighten them up with a spanner. 7/16" hose can then be persuaded to fit over the barb and is sufficiently tight that it's unlikely to come off even without a clamp.
 
Ok thank you very much for all the infomation, looking to order the bits the next few days, might be a little bit longer till the install as im waiting for a case to be realeased, il post the pictures when im done.
Thanks again
 
Will the pump be strong enough to do both graphics block and cpu with a double radiator? do you think there i can add a small 120 at the front aswell?
 
That x2o 750 might struggle with all of those components. I was originally looking at the OCUK V8 kit which is very similar and decided to build it all myself so that i could use a D5 vario instead as it was considered to be the most reliable pump on the market. I've also seen quite a few people posting about that bay res/pump combo being quite noisy too. The EK dcp pumps are a good alternative to the laing pumps.

I've got no knowledge on the case, but from looking at the images above, I'd say you might be able to fit a 240mm radiator in the front if you lose the drive bays and put your hard discs/ssd up in the top. Might make sense to run a tube reservoir and separate pump as this will keep your bays free for drives. Have a look for the reviews on the case and you should be able to find out what configurations are available for water cooling.
 
do you think i can use the graphic block and cpu block with only 1 radiator? and the pump will be strong enough? or do you suggest chosing something differnt?
 
It's the blocks for the gpu and cpu that create the biggest restriction. Radiators barely add any restriction. I had my doubts about the bay pump which is why I decided to go with something else. It should work, but flow rate is likely to be poor and you'll have a hard time bleeding the loop with low flow rates. There is a review of the pump on Martins liquid lab site if you want more information.

One radiator isn't going to be sufficient to keep temperatures low or keep noise down. I had a look at the review for the 350D yesterday evening. (OC3D) You can fit a second 60mm thick 240mm radiator in the front if you take the 3.5" and ssd bays out. You can also fit a 280mm 30mm thick radiator in the top instead of a 240. (Although there aren't many decent 140mm fans for radiator use about yet. The swiftech helix is about the best but hard to find and quite expensive) I'd stick with the 240 to make things easier with the fans. This should be ample for cooling both your cpu and gpu.

Depends on what type of radiator you use.

a 60mm thick 240mm will do a cpu and gpu fine, if you go for thin ones at say 30mm you will need at least 360 radiator space.
 
Decided im gonna stay with the 30mm rad that comes in the kit and im adding a 120mm rad in the front just to keep it nice and cool, im not gonna have loads of room to add a 60mm i dont think.
 
The kit comes with 1/2" barbs. You'll need an extra pair if you intend to add a radiator, plus an extra pair for another block. (GPU)

90 degree fittings - Screw this into the block/rad and then the barb into it.
Additional barbs - These match the ones in the kit, though they are out of stock. (although so is the raystorm kit)
 
Do you think these style of fittings would be good if i have to move my pc long distances to lan and back which is a 300mile round trip?
