Proposed CPU loop: Thoughts? - Page 2

post #11 of 23
Thread Starter 
What do you all think about these 280mm rads. I'd like the best 240mm through 360mm I can get for sub $120 or so, but 240 and 280 preferred because fitting a 360 might get tricky. Thick rad > Thin rad aswell?

XSPC EX280 $63
EK-CoolStream Radiator XTC 280 10 FPI. FPI? $83
Coolgate Dual 140mm Ultimate Heat Exchanger Radiator Low FPI? $83
Phobya G-Changer - 280mm FPI? $74
Black Ice® GTS Gen Two Stealth 280 30 FPI. $78

If I go with a 280 rad, What are the best 140mm fan's I can use for a rad? What about:

TY-140
COUGAR CF-V14HB
Yate Loon D14SH-12's
NZXT FN-140's
Bgears B-Blaster 140mm


I need input pretty bad

Looking at the Paint diagram above, the restriction in the loop isn't going to be the components really, it will be the gravity issue.

Using an XSPC Bay RES has the opportunity to transfer pump vibration into case making rattles or a hum. If you have the ability to isolate the XSPC Bay RES, then the solution is a good one.

With all of that said, your best bet is two DDC-1T (MCP350) pumps for the XSPC Bay RES in a dual setup. This would provide plenty of head pressure to overcome the gravity, good flow around 1.5gpm and the heat dump of the pumps are lower than any of the other DDC series or a D5.

The Tee-line in the loop is at an odd place. It would be better for the loop service placing it at the lower Kuhler. Having the Tee-line right up there in the middle only allows the top RAD, RES and pump(s) to properly drain in the loop. The CPU and GPUs and the two Kuhlers will be liquid trapped. It's a pain rotating a large case like that to properly drain everything.

Hope this info helps some.

His Kuhlers are not part of the loop and won't be modified. The loop is CPU only. I believe he also PMed you about the DDC pumps.

If you're not modifying the Kuhlers... I don't think it's going to reach the bottom intake like your diagram. Maybe on other side of drive cage?

Thanks, yeah as iCrap said the CLC's aren't involved with the rest of the project here. I hadn't thought about vibration, I'm sure I can over come it with rubber washers or something though. As for gravity & pumps, now that you know the CLC's aren't involved do you think I need 2 pumps for a CPU loop? Is it bad to have the rad up top?

Should I gauge how much tube I need, hook up everything outside the case and let it ride for a day first?

Another thing, I was going to use distilled water, anything I need to add to it? Would I be better off just buying a coolant?

not sure about the first question but distilled water is good and this . . .

http://www.frozencpu.com/products/11441/ex-tub-705/IandH_Silver_KillCoils_-_Antimicrobial_999_Fine_Silver_Tubing_Reservoir_Strip.html

i got my water ( 1 gal jug) from local Taget store for like $0.84.

edit: i also bought this as an alternative but never used it . . .

Yeah I have a kill coil in the buy list in the OP, So would everyone agree no real reason to go with a coolant? should I even bother adding a anti-corrosion additive to the distilled water?

Back to another question, would it be a good idea to just configure the entire CPU loop outside the case and run it for a day, then ofcourse if no issues just kinda hook it up in the case/to the CPU?

1/2" x 3/4" Compression Fittings for 7/16in. ID X 5/8in. OD tube or 7/16" x 5/8" Compression Fittings for 7/16in. ID X 5/8in. OD tube ? Hearing some mixed things now, and is it a bad idea to set up entire WC outside of case and run it outside it for a while before adding it or moving those tubes going to be too difficult?
