First Timer WC a 3930K and 3 7970s - Parts List and Plan Looking for Input!

post #1 of 10
Thread Starter 
XSPC Twin D5 Dual 5.25" Bay Reservoir
Dual Swiftech MCP655 Variable Speed Pumps
XSPC EX360 Triple 120mm Crossflow Low-Profile Radiator
Alphacool Nexxxos Monsta Dual 120mm Radiator
Tygon Silver Antimicrobial Tubing 1/2 x 3/4 - 10 Feet
XSPC RayStoirm CPU Liquid Cooling Block - Black Edition
EK FC Bridge Triple Serial CSQ - SLI Connection - Acetal
EK Radeon HD 7970 VGA Liquid Cooling Block - Acetal CSQ
Bitspower Ultimate G 1/2 x 3/4 Compression Fittings
Bitspower Dual Rotary 45 Degree Compression Fittings

Total Cost $1,116.26



This will be in a Cosmos 2. Should I go with any other parts instead of what's listed above?

Will a 240mm AlphaCool Monsta and EX360 be enough to cool the CPU and 3 cards? I'll be using high RPM fans as I don't care that much about noise. Haven't decided which ones yet. Thanks guys!

Yes all of these parts look good, but you may want a silver kill coil to get rid of bacteria/algae.
A 240mm and a 360mm will be plenty, especially since the monsta it super thick.
For fans most people go with either Noctua or Gentle Typhoon AP-15s.

If you don't care about noise, go with San Ace H101 smile.gif

thanks legonut. my understanding is this silver tygon tubing has silver material in it that prevents microbes algae etc. that netgates the need for a kill coil. for fan right now im leaning toward the cooler master excaliburs. i hear theyre a little noisy, but have great static pressure output and are easy to clean with the removable blades. the san ace is very tempting though. not sure i want to use 38mm fans.

That excalibur fan does not look good for use on a radiator, firstly staatic pressure fans tend to have less blades that are flatter and much wider. Those on that fan are relitively thin and angled which would be more geared towards air flow, also those holes in the housing look good but they definitely can't be doing anything to help the airflow.

I would go for some Sythe S-Flex fans, Corsair SP120 fans or the fans Legonut suggested they would be much better.

You certainly have enough Rad for your setup and you are doing very well too for only $1100 I just ordered a very similar loop and it cost me $1700 eek.gif

A word of caution with that cosmos 2 case you have very limited space at the top. There is about 44mm from the top of the case to the top of the motherboard, and remember you also need room so that your fittings in the rad won't hit the motherboard heatsinks or IO ports at the back, It seems you have checked that and got a thin enough rad but I just wanted to make sure you knew about that issue.

Thanks stickeelion. The CM specs have the static pressure right around 3.5mmH2O, which to my understanding is really good (albeit w/ noise). I guess since it's coming from the manufacturer I should take it with a grain of salt. I hear conflicting reports on the holes in the frame of the fan, some say its good for static pressure, others say no. Don't know what to think there.

I'm definitely aware of the thin rad issue up top and have planned accordingly. I listed the cross flow radiator by accident, I'm actually going with the one with the standard ports. I've developed concerns about the holes getting in the way of the rear I/O ports on my R4E (especially given the 1/2 x 3/4 tubing I plan to use) and was thinking a rad with in/out ports further in from the edge (closer to the center) of the rad would give me a little extra comfort space. Specifically I'm now looking at an AlphaCool ST30. Does that make sense? I also wouldn't mind keeping it consistent and going AlphaCool for both rads. The input is much appreciated!

Never trust fan specs. ST30 isn't a great thin rad. AX outpaces it by a yard.

Good to know on the ST30, tsm. I was also thinking about an XT45, but I think 45mm is going to be too close for comfort up top. As you know the R4E power connectors will be right there at the edge of the top of the board and need some clearance for the plugs/wiring. I'd like to go for an AX360 over the EX360 as its the newer generation and probably a hair better on performance, but the 40mm thickness scares me compared to the EX360 35mm thickness.

Stupid Cosmos II. Wish I knew I was eventually going to do a custom loop when I bought it. Oh well...Paid 350 for it at launch and can't justify scraping a $350 case after 15 months of use.

I ground my pcie connectors down. If ya gotta make it fit, ya gotta make it fit! Actually I ground a lot of things down, my fans, pcie plugs, etc. I would look into one of these too:

just occured to me, you could turn the rad around so that the ports are at the front near the 5.25" drive bays...
