12volt Water pump goodness
This is the best 12volt pump I have gotten my hands on in the last couple of months since I start water cooling. My current system uses a rule live well pump that is loud and adds heat to the water. I got this one from ITT Jabsco today here are the specs.
12volt Magnetic drive coupling 15 lpm / 3 gpm @ 1.2 meters/4 foot head 4 gmp @ 1.7 psi pumps water at 100 C / 210 F Current draw 1.2amps full load Continuously rated Dim 5 1/2in X 2 1/2in (This thing is small enough to fit in the palm of my hand. Wish my camara was working so I can show you a pic of it in my hand.) I pluged it into a power supply and it didn't make a sound while running in my hand. I set it on top of my case and it's still very quiet.

looks like a nice pump, and it is actually continuously rated. The gph is a little low though, you might need two

the fact that it looks like it could be easily mounted inline to the side of the case impresses me....

Hmm.. I wouldn't worry about flow rate with that pump (240gph?) because the pressure drop for this one seems to be pretty slim. Post some numbers when you get a chance

At 4 feet, it just doesn't have any kick, and because of the pressure drop across from the waterblock alone, the effective flow could easily drop under 50 GPH. Still, lower might not be worse. As long as the rig is really optimized for flow (no kinks, bends or elbows, low-pressure drop rad, and simple waterblock) this could turn out to be the "little miracle watercooler". Here's a little bit of math: 1 Pascal=.004 inches of water 1 psi=6895 Pascals Inches of water: 48 (for 3gpm, 180 gph) Pressure drop: 48/.004=12000 Pa Pressure drop: 12000/6895=1.74 psi In other words, as long as the rig drops no more than 1.74 psi@180gph, then it'll work. |

It's installed, after two trips to Lowes for fittings, 4x4x2 marine box, and hardware.
Temps after 30 mins with the covers still off. Room 34/35 Cpu 32/33 I had to complete redo my whole water system to get it to fit. I will post pics tomarrow.

the CPU temp cant be lower than the room temp (unless youre using a pelt or something, or very cold water). your measurements must be off, or you got them mixed up lol.

Yes, they can when the case temp sensor is soldered on the board next to the northbridge. So the case temp is not correct anyway. My room temp is around 25C. But I can't complain to much as I won this motherboard from AMD. I would like to get a better motherboard, but with Hammer comming and Amd talking about changing the socket it just wouldn't be worth it right now.

Hum...
I found it here, but no specs: http://www.jabsco.com/util.asp And on second thought... 3gpm @4 ft head isn't bad... could be run dually... I went over to the Jabsco website, and requested more info (the spec sheet isn't available). Maybe if we could get a performance chart... So how much does it cost? what's the fitting size? We'll find out... |

It's rated for continuous duty, so it SHOULD be as good as anything else.

I've seen it on the web for $95.00 . (Am I going to spend that much? Hell no!)
I'll do a search and see whatelse I come up with. At this point, even a paristaltic pump looks good... |

I got the specs for the pump above, including the performance curve. (let me know if I should post it).
In short, it'll do 4 GPM(240gph) @ 1.74 psi (4 feet), but can only handle 1 psi (2.3 feet) at 5 gpm(300gph). It will however handle 2.80 psi (6 ft) at 1.32 gpm (80gph). It cannot handle more than 2.90 psi (6 feet 8 inches). I think it's a little underpowered. Connections are 3/4" ID. 5V@ 1.2A = 6 Watts (definitely underpowered). It could be run in a dually, but there would have to be something to prevent the two outputs from leaking into each other (a flap valve?). |

Hey... check out this pump:
http://www.oberread.com/laing.htm The SM-303 is rated with 15 dBa !!! (only 2gpm at 4" head) The SM-909 is rated with 30 dBa ! (4gpm, at 10" head) |

powerful. they look pretty bulky tho...plus they arent mag-drive pumps. need bigger pics or dimensions of the things to be sure tho...

They might not be mag drive, but as long as they perform, and they're quiet, who cares?

true. but a seal / bearing is just something that'll eventually wear out and need to be replaced. :shrug:
how much do they cost tho?? |

Also true, but being rated to 50psi, I don't think I'd worry about it. That carbon bearing is often used in high pressure aps.
I don't know, maybe I'm wrong. I can't find the price anywhere. I requested it, but I haven't received it yet. |
