Will a XSPC Rasa RX360 kit + 240 rad be enough for 2x6970 + C2Q?

post #1 of 37
Thread Starter 
I'm looking to do my first watercooling loop, and I just want to make sure the equipment I'm planning on getting will be sufficient to cool everything.

My plan is to get an RX360 Rasa kit to cool the CPU (a Core 2 Quad 9550), and two 6970s with full cover waterblocks that I already have (one with a EK rev 1 WB, and the other with an Aquagrafx; both cards are revision 1 reference models). I also want to add a 240 radiator to help decrease temps, but I'm not sure on what kind to get because I'm going to have to deal with a certain space restriction.

Everything will be in a CM ACTS full tower case, with the 360 rad up top, and the 240 rad behind the HDD cage. This is where the space restriction comes into play with the 240 rad: there needs to be less than 1.5 cm between the bottom of the rad and the mounting holes for the screws in order to clear the bottom of the case:

450

My main concern right now is whether the XSPC X20 750 pump will be enough to maintain a good flow rate. I tried using "Martin's Pump and Rad Optimizer" excel sheet, and I'm a little confused on how it works. I wasn't sure what to put for the GPU blocks since it didn't have anything for 6970s, but it gives me less than 0.5 GPM with everything I want to get. My understanding is that I want to maintain at least 1 GPM, right?

So my questions are: will the Rasa pump be enough, and what 240 rad should I look at getting that fits my space requirement?

Thanks in advance! cheers.gif

Yup, they also have a 240 extreme kit.

The major difference in the RASA RX360 Kit and RASA RX360 Extreme is listed below!

-Pump Upgrade to the D5 (Alphacool VPP Single)
-CPU Block upgraded to the newer, better performing Raystorm
-Choice of tubing color
-Compression fittings instead of barbs

Its like a 150 dollar difference over the basic RS kits and about 100 bucks over the RX kits. The pump upgrade itself is alik a 120 dollar difference and the raystorm block is 62 bucks if you buy it separately. The other upgrades may sound minor but trust me fittings and the small things add up pretty fast.


If your worried about clearance for the area your looking to mount a 240 rad, I heard the Black ice GT 240 rad is good. I believe its a "low profile" rad. I have also heard many good things about the XSPC EX240 rad. it is their slim line rad series and supposedly performs very well.

I have had a think about this and I am going to say no on the pump for a couple of reasons: As you are using this for BOINCing you are going to want a reliable pump. The X20-750 has been known to have issues and the pump is pretty weak, you will get acceptable flow rates (~0.75GPM) but you can do a lot better


So your options are:
  • Build a fully custom loop
  • Go for a XSPC Extreme kit with the 655 pump and the Raystorm block
  • Buy the normal RX kit and replace the pump with a D5 (MCP 655 / PMP-450) or a DDC (MCP350/5/x / PMP-400)

As for the rad, 15mm from thread to end is pretty tight. I know that the RX series are bigger than 15mm in that dimension from my measurements, however the Swiftech MCR-220 QP is 19mm (check the top right drawing) so you might be able to squeeze it in.

There are likely a few more out there that are <15mm, but I wouldn't know for sure about the dimensions.

The pump on the RASA Kit is the weakest link, get a D5 or DDC pump, also I think a extra 120mm will be enough, flow will go as this:
CPU>120mm Rad>GPU's>360mm Rad>pump>CPU

Check Dazmode.com, the Raystorm kits have Ex series radiator, XSPC Raystorm block, compression fittings and D5 or DDC pump, just add a pair more of fittings and a 120mm and you are good to go.

Thanks to all three of you! thumb.gif

So it sounds like the D5 pump is recommended, so I'll be going with the Rasa Extreme kit that Ryanhabs mentioned. I had heard before that the X2O 750 pump is the weak link in the Rasa kits, so the Extreme kit looks like the perfect option.

And I'm not concerned with rad thickness, but distance between the bottom screw and the bottom of the rad, I'm sorry if it wasn't clear in the picture. There have been a couple of guys in the ACTS case club that have put rads behind the HDD cage, so hopefully they'll be able to get back to me with some suggestions.

@ Ivan Do you think there would be a big difference between a 120 or 240 for the second radiator?

That is what I was measuring. It is going to be tight. As you suggested, the best thing to do is find someone who has put a rad in that location and ask them how they did it. You might have to mock up some kind of mounting arrangement.

Yes, you got it right. smile.gif I know I've seen at least one build log with pictures of a 240 rad behind the HDD cage in my case, I guess I'll have to go hunting for it, until I hear from someone who has done it before.

I've had a 240 there for quite a while, but have changed it for a 360 now. I've tried quite a number of 240 rads there and as i wrote in the ATCS 840 thread, a HW-Labs GTX 240 will not fit, Swiftech MCR-220-QP will not fit.

Magicool Pro Slim 240 Will fit, with ease, but that is a very low performance radiator.

Suggest about 5 rads that you have eyed out and i can try to find some measurements on them and compare them to the drawings i have here.

Thanks, I think it was your build log that gave me the idea of how I wanted to organize my loop.

Part of the reason I am asking is because I'm not sure of what rads to look at for a good price/performance ratio, and I know the space requirement cuts out a lot of options.

Can you tell if an XSPC RS240 or EX240 would fit?

Or do you think it wouldn't be worth the trouble, and I should just cut an opening in the bottom like you did? I guess if having to deal with the space requirement is going to force me to get a sub-par rad, then I'll go ahead and get something worth buying and cut a hole.

If this drawing is correct a correct scaled down drawing of the real radiator the EX 240 has a "bottom part" that is ~ 16.88mm
That is a bit on the large side, the Magicool that i had had a "bottom part" that is ~15mm and it was a perfect fit, it could be that you could force the EX in.

The RS was a bit harder, did not find any drawing of it. I did find this picture, and using the fan space between the bottom fan holes that is 120mm IRL, i got a measurement on the "bottom part" of somewhere between 15,12mm and 16.5mm

So it looks like the RS is slightly better when it comes to fitting it, but then again all this dimensions are based on drawings and pictures and just simple maths so i could be wrong.

Would be better if someone with a RS or EX could measure it up.

Then again it took me 20min with a dremel to do the cutting, and the end result is pretty OK
399

I just used some hobby fuel tube and cut it up to protect the rad, with this cutting there is no problem with dimensions.
