Advice for quiet pump with a reasonable amount of head?

ZenTrickz · Post by **ZenTrickz** » Fri Dec 10, 2004 9:44 pm

Hello everyone! This is my first post at SPCR. I've been looking into a water cooling over the last couple of weeks. I'm a bit baffled at the assortment of pumps that are out there. Are there any pumps that have enough head to do a reasonable overclock, but are still nice and quiet? Let me list my WC components I have planned (don't be afraid to critique these as well, I'm still pretty new at this!).

Mid-Tower Case (Lots of available realestate)
Black Ice Pro II Dual 120mm Radiator (Mounted to roof)
Globe 120mm Fan x 2
Swiftech MCW6002 For AMD-64
Silverprop FusionSL GPU Waterblock (For a GeForce 6800 GT)
Tygon 1/2" tubing

Suggestions and advice please. Please be specific.

You want a DDC. Because it has 3/8" barbs, you probably should match the rest of the system to that. At ~1gpm, the smaller tubing won't cause undue restriction, and it will bleed more easily. Specific enough?

3/8" can stretch over 1/2" barbs right?

I'm stuck between wanting a DDC and an Eheim 1048 heh. It looks like Cathar still recommends the 1048 over DDC for quiet setups

Lol, plenty specific HammerSandwich. Hmm, although what's a DDC?

It can be done, but it ain't no fun. Also depends on the tube. Hope that help, zoob.

i would recommend going with 7/16in tubing.

if you spend more on tygon or clearflex even rather than .79$ stuff at a hardware store and a pot of boiling water you can stretch it with some effort, but get ready to be frustrated as crap when doing it.

Also I'd get teh DCC, the 1048 is quiet, but a wimp, for just a cpu+rad loop it is okay, not the best.. but adding a gfx card block it really is too wimpy. I have 2 of them and like their quietness but in my next system I'm switching to a dcc. btw I also have 2 csystem mark2s if someone wants them for $50(paypal)+shipping, never plugged in but I threw out the boxes.

Also that radiator is thick, the orignail 2 120mm fan one is only $50 and should work better with low airlfow fans.... you have alot of heat to get rid of tho so I don't know... I gotta get back to work.

Ok I've decided to go with a DCC pump. Thanks all. Now I need some recomendations for a dual heatercore/radiator. Something preferably that will work well with low-flow fans.

Black Ice Pro II Dual 120mm Radiator above doesn't seem all that thick. Or is it?

Hmm maybe I should go with the Papst 4412 fan instead. I heard they move more air than the globes.

Whoa! Nice. Thanks man

heatercores arn't the best with lowairflow fans... the bip u linked to would probably be better... procooling forums has alot of information...

btw thats the bip i meant earlier, the extreme ones are too thick

I'm actually getting good results with
6x6x2 heater core
coolingworks shroud
2 x Nexxos 120mm fans stacked, with spacer between 'em on the "pull" side

Slightly undervolted (or with slight PWM) I'm getting somewhere between 12 and 17 dB and temp results approx 1C higher (MBM on-die reading) than with the same heater core with a single 120mm Panaflo L1A at 7V (which was in the 22 to 26 dB range). Note that if you undervolt stacked fans, you should undervolt them both by the same ammount, otherwise one "drives" the other. I just used a 3-pin 'Y' cable. If you're using resistors to undervolt remember that the fans are now in parallel for calculating needed resistance. If you're using a rheostat or PWM controller, it's a non-issue.

I don't have BIP with Nexxos temp measurements, but the heater core, with Panaflo, significantly out cooled the BIP with the same Panaflo (idle temps similar enough to be measurement error, but 100% load temps about 8C apart). Note that these were from the same cpu/mboard/wblock/case/tubing/pump - just the radiator was changed, so it's somewhat "apples to apples", BUT it's readings in MBM, which is highly suspect, so all I can really say is that the heater core out cools the BIP, but not by how much.
