i think i've finally resolved to go aqua-style :)

just wondering...what GPH do you think is appropriate...and not total overkill (want to save a few bucks anyhow)...for a now 1 gigahertz athlon t-bird 266fsb?

noise isn't that big of a concern...as long as its still < avg air fans/sinks

was thinking around 250gph?....

I assume you are talking about a pump. In that case, I'm using a Laguna 220GPH pump modded to give around 260GPH. This is not necessary though, you can use anything as low as 80, but I would recommend no less than 120 and 150 is prefered.

Depends on your block and radiator. Maze style blocks and Cooling Cube radiators like big pumps. A simple block and heater core will let you get by with less. What block and radiator are you going to use?

im probably going to get the DD cooling cube radiator, copper vid card block for new gf3, and maze1 block for 1.2 t-bird

the pump i already found hehehheh....we bought a 1/4hp pump to get water out of basement in case of flooding...but its been 6 years since we've had a problem....*shrugs*....u have to prioritize :)

and the noise isn't a problem, btw...since it has a variable setting on it (thank god)...it doesn't make any more noise than an oem heatsink fan at around 200 gph...any higher than that and the dB just skyrocket....which i guess is ok since when im really pushin my machine playin unreal tourney i have the audio on so damn loud i won't really notice...heh heh

Is that pump rated for continous use?

yes it is actually!...it was originally made for outdoor fountains and the like....it should have a decent life span to it

Cool! Be warned that all of the 90 degree bends in the gear you have selected will dramatically cut the flow in your system. I found a 700 GPH Danner to be optimum with a Maze 2 and Cooling Cube. I don’t believe all pumps rated GPH are equal. Eheims seem to be stronger than Danners for the “rated GPH”. Lets hope your pump is more like an Eheim.

True, looking at gph alone does not answer the question, because standard gph ratings are based upon 0 head (i.e., pumping on a horizontal plane) and no flow restrictions. Better pump mfctrs. will also provide statistics for gph at different heights and/or the pressure they put out. As a general rule direct drive pumps are more powerful than magnetic impeller pumps, meaning that they should lose a smaller percentage of their rated gph as resistance goes up.

This is very true but the reason I like to use mag drive pumps is that they are far less prone to leaking. This is important when mounting a pump inside your case.

Well, I agree that mag drive pumps are *theoretically* less prone to leaking, because they have many fewer moving parts, but *some* mag drive pumps leak like seives (cough**Danner**cough cough).

I prefer mag drives because they're quieter and should be more dependable over the long haul.
