Cooling a 6950 and a 2500k. Complete n00b

post #1 of 6
Thread Starter 
I've always thought water cooling is a good looking idea for cooling and the fact that it makes far less noise than air cooling is a huge bonus to me. Because of this, I've been toying with the idea of using a loop to cool my 2500k and my 6950 at the same time. I'm not looking for anything fancy as my case has no windows etc, just something that works and most importantly, gives me the most for my money in terms of cooling ability per £/$.

I'm completely new to the idea of watercooling but know a few things. If I want to create a loop I'll need to buy blocks for both the CPU and the GPU. Beyond that I have no idea where to even start.

Could anyone help me out and point me in the direction of the equipment I would need and roughly how much it would cost? Any help would be much appreciated.

PS: I think I might be getting another 6950 in the future. Would it be easy to add that in to the loop with another cooling block?

Quick and easy solution would be to get an XSPC Rasa 750 RX360 kit.

You will need space for a 360mm rad but the kit comes with mounting brackets for external mounting if needed.

You would then need to get a waterblock for your card. People are somewhat negative about EK blocks at the moment due to an issue with the nickel plating coming off them, so either an XSPC or koolance block is generally what people recommend.

On top of that you will need some distilled water or deionised water from a garage or grocery store and a silver kill coil to stop bacterial growth in the loop.


Also, for the graphics card block, make sure your card is reference design or the block wont fit.

I'm doing something almost identical to your loop, and I agree with the previous poster, that the XPSC Rasa RX360 kit should be plenty for a single graphics card and 2500k. When all was said and done it costed about 250 bucks for the kit plus extra tubing in the color i wanted (I bought 12 feet, it was the perfect amount with some left over), an IandH silver KillCoil, and 6 fans (The Yateloon DSM12M's are what i got and they're great, but the screws that come in the RX360 pack are too long for the 25mm fans and I punctured my radiator in the process, dont do that. Either use double sided tape or go out and buy 1" 6-32 screws).

As far as adding a second graphics card, I had a terrible time getting a straight answer saying whether or not the RX360 will suffice, and the common answer i got here was that I was going to need another radiator to add to the loop. I feel that adding an RX120 should suffice, but most here went between that and the RX240 in addition to the RX360. XPSC makes a great cooling block for the 6970, which'll also fit a reference 6950, so I'd definitely go with that. Overall, it's about 250 for the CPU loop, and another 300 or so to add the 2 GPU blocks (90 a pop) and another radiator (50 bucks), I personally decided to stick with the CPU loop for now and add the graphics cards when I have a little more money. If you have anymore questions feel free to ask. I've been researching this day and night for the past few weeks

What you need:
Waterblocks for the parts that needs cooling, in your case, the CPU and GPU. Note that it is only the nickel plated EK blocks that you should stay away from. Nickel vs Copper is stricktly an asthetic thing.

Radiator(s) which is what will cool the water. A thick 120.3 (meaning 120mm wide and 3x120mm long) radiator could possibly cool even a CPU and 2 GPUs nicely.

A Pump(s) to well, pump the water around in the loop. There will also be various "tops" for pumps that can be acquired and installed instead of the stock one for increased performance. Choosing the right pump has to do with how large or restrictive your loop is so, IMO that should be the last thing you choose. Also having more than one pump in a loop is only for the very very big loops, you wont need that.

Tubing and Fittings for connecting everything. The two popular types of fittings are Barb fittings, which is just a small stud that you pust the tubing onto, and Compression fittings which is kinda like a barb, but with an outer ring that you screw around the tubing to secure it in place.

Either a reservoir or T-line for filling and bleeding (removing air bubbles) the loop. Note that you can buy reservoir and pump combos build into each other.

Fans, to mount onto the radiator(s) to increase cooling performance.

Distilled water and anti algae/bacteria growth additive, like PT Nuke fx.. Do NOT buy premixed and/or coloured cooling fluid. Its way overpriced and might cause gunk to gather in you loop and clog it.

Building your own loop from scratch can be a mouthful if you know nothing about watercooling, so I would too recommend buying the XSPC Rasa RX360 kit. All you need to buy is a GPU block and fittings for it. If you want some color in your loop you could also buy some coloured tubing and use instead of whats included with the kit. And of course, the distilled water, a few liters, and PT Nuke or equal antigoo additive.

Well here's the thing, unless you're looking to upgrade your case, the only way you're going to be able to water cool is with an external rad and drilling holes in your case for the tubing. -the downfall of budget cases

However, you could probably mod the top of your case since your psu is mounted up there you could probably fit a 240mm rad up there, you just would not be able to use your top drive bay.

Basically you'd have to drill the holes and buy a rad mounting kit or something then go from there, You'd probably want to go with a slim rad too.



So the next best thing to do is either:

A. Buy quieter fans for your cpu cooler, like some noctuas, and possibly an aftermarket gpu cooler with larger more quiet fans.

B. Buy a corsair h50/60 as they're quiet if you don't have it set to max rpms in bios. And an aftermarket gpu cooler.

Oh yeah I forgot about your case, really not made for internal watercooling loops. There is of course an option C. buy a new case, you could use one. I used to have that case, and I wouldnt dream of watercooling anything while using that, or having two GPUs inside it.
