Some water cooling advice needed! (First system)

post #1 of 12
Thread Starter 
'lo there folks! I've been on air pretty well off for nearly 5-6 years doing some simple OC stuff, and recently got a 2nd Sapphire 6970. I've never OC'd my GPUs, due to never really needing the speed or power (though do we ever? ). Recently, with both 6970s in, I've run into some pretty startling heating issues. Right now, at idle, my main GPU is at 64c according to Real Temp (2nd GPU is at 44c). I know this is because of the cards being beside each other (I've only the short Crossfire bridges, and can't find anywhere in Canada that sells the extended ones).
So with this, I've decided that water cooling is the way to go, to help now, and for future endeavors! I've got a HAF 932 Black edition or a Thermaltake Level 10 GT case to my name to do this in. All the components are my sig rig, and I've a few questions for you guys (I'll be honest, I looked at NCIX.com, and was well overwhelmed by all the options ). I've a Cosair H70 cooling my CPU at the moment (49c idle, 65c under load). Since it seems decent for temps, should I look at building a custom loop for my GPUs alone? Or is it simply better to just tie it all together (for space reasons, less loops, etc)?

I'd first off like too send a huge thanks to Juggalo23451 for all his videos and posts on water cooling.

I was looking at getting the following:

Radiator: XSPC RX360 Triple 120MM Fan High Performance Water Cooling Radiator

Pump: Swiftech MCP350 12V Industrial Water Cooling Pump 3/8IN Barbs

Reservoir: Ek Multioption Res X2 250 Basic Water Cooling Tube Reservoir G1/4 Acetal Glass

Tubing: 2x Primochill Primoflex Pro LRT UV Green 3/8IN ID 5/8IN OD Tubing (10 Feet)

CPU Block: Ek Water Block EK-SUPREME HF Acetal LGA1366/LGA1156/AM3 CPU Water Block G1/4

Barbs: 8x G1/4 Straight Compression Fitting for 3/8IN ID 5/8IN OD (4x GPU, 2x CPU, 2x Reservoir).

Ended up going with:

Coolant: Distilled water, with "DazMode Protector".

Fans: I've got several Noctua 120mm NF-S12B's that I'll be using (at 1200 RPM).

GPU Blocks: XSPC Razor 6970 Full Cover COPPER/ACETAL Radeon HD 6970 GPU Block G1/4

"Startup Kit" (Pump/res, rad, some tubeing, CPU block): Rasa Uber 750 RX360 Complete CPU WaterCooling Kit

Barbs: 4x BP-MBWP-C01 G1/4 to 1/2IN Straight Barb Fittings

Crossfire connectors: 2x Koolance Adjustable Dual VID Connect Nozzle for SLI or CrossFire Cards

I picked up a bunch of 5/8th OD clamps as well, and some 7/16th ID, 5/8th OD hose, just in case I needed some extra.


Now, that all said.... Am I out too lunch here thinking this'll actually work? I defer to your guys' expert opinions on this one, as I'm still in shock at all the different options that are available for, well, everything!

Any help and suggestions would be greatly appreciated! I'd like to have this cooling system last for awhile (as long as a pair of 6970s would in today's market anyway! ) if possible, so I've made some more expensive, but worthwhile (I hope!) choices in getting some better parts.

Your radiator is listed as a gpu block, but other than that it looks great. You will need a good amount of cooling. Maybe 4x 120mm (split however you want). I think they even make larger radiators (200mm).

You would get better cooling by integrating the CPU and ditching that all in one unit. Besides, it will look better

rx 360 or rx 480 would work if you want silence for the two gpus

if you already have an h70, then just keep it.

also, try to get the xspc razor 6970 blocks. they perform better and are cheaper than ek's block

For me, money isn't a huge issue. I'm an elevator mechanic and that leaves little time for anything other then fooling around on a computer on weekends. I'd like to simply get something that'll last, and that will work well. Noise however, is. I'd like it quieter, since this is in my bedroom at the moment!

Thanks for the posts thus far! I'm going to look into those XSPC Razor GPU Blocks right now!

[EDIT] So you're saying that XSPC Razor 6970 Full Cover COPPER/ACETAL Radeon HD 6970 GPU Block G1/4 would be good for GPUs, and that The Rasa Uber 750 RX360 Complete CPU WaterCooling Kit (or at least the rad from that kit) would be a better way to go?

Yesh, you got it. Make sure you have room for the rads though, theyre pretty fat.

For quietness, get low rpm fans. i recommend Gentle Typhoons, but anything 1800rpm and lower would be idea since the rad performs best around 1000-1600 rpm.

any reason why you want 3/8 barbs instead of the usual 1/2

After doing a good bit more looking, I realized that mistake. The easiest way I see things, is to go with 7/16th" ID piping, with a 1/2" barb. In the end (yes I've already ordered) I'm going to trade the H70 I had to my father (another gamer though less into wanting top graphics then I am, and thus is only running a single 5870), and ended up with the Rasa Uber 750 RX360 Complete kit. The Rad can be jury-rigged fairly easilly, be it to an external stand, or inside to the top / back of either my 932, or the top of the L10, since I only use 1 CD-rom bay, and no HD bays (I use a PCI-E HD). Space isn't an issue, thankfully! I picked up a pair of the XSPC Razor 6970 Full Cover GPU Blocks, some spare tubing, and fittings (1/2" ones). I also picked up a pair of "Koolance Adjustable Dual VID Connect Nozzle" for block to block connection for my GPUs. All the barbs I made sure were 1/2" (none of them are the compression fittings, for my sanity if nothing else). I know it seems rushy, but after looking at the stock levels (and seeing that most things were at 2-4 remaining) I figured the sooner I ordered, the better (Not to mention the temps my comp is at!).

Thanks again for all the help!

Looks great! Don't forget to post up a buildlog -- I will be looking for it.

Sounds like you know what you are doing for the most part. If I were you I would surely leave the Corsair H70 there as you will have better temps on your GPUs and you would not have to worry about your cards heating up your CPU. Do make sure you can fit that Radiator in your case though. Maybe also use a 5.25 bay resevior as its a lot easier and you don't have to worry about a mounting spot for it, as I made the switch to that and it has been a lot easier for me.

As for the Rad. fans Kick is right about the Gentle Typhoons as they are quiet yet have enough pressure to push the air through the fins. Or you can just hook your current fans up to a fan controller which is what I did.

oh yeah, you can drop that res and grab the xspc restop for the pump, or a dual bay res for it. that way you dont have to fiddle with 3/8 tubing
