recomended gph for pump??

[bobt17]

i was wondering what everyone thinks is the best gph for for a pump to use with watercooling?

[rivercom9]

I don't have much experience in H20 cooling, but from what Ive learned, somewhere from 300gph is decent for a normal setup. That is if you do not have a lot of high inclines. If you do, I believe most people who have had more experience in H20 cooling would reccomend getting something over 400gph.

[deathstar13]

depends what you making. lowest i would go would be a 120 gph.
i think 500-700 gph is ok but is alot.

i use 350 gph danner mag drive with large 5/8" hoses ,great pressure and ciurculation.

the smaller the hose the small the pump u can use and it still be effective. even a 350 like mine is kinda extreme. but serous performance.

hmm thanx for the replys. the reason i want to know is i have a danner 250 gph and was wondering if a higher or lower gph pump would get me a little better performance...

From personally experience that is perfect. I just modified mine and my little 120 can't even make a complete circulation. You don't want it to fast so, if you don't have any 3 feet climbs that should be ideal.

There are (2) main components involved with regard to liquid flow vs. cooling. The first is the cpu cold plate, and the second, the external heat exchanger to ambient. From my experience, cooling up to 1000 Watts, 1 GPM (60 GPH) is more than enough to do the job if both heat exchangers are built within reason. Perhaps with a "bad" heat exchanger, more flow would be needed. Again, from my expereince, the limiting factor is how much air can be flowed though the heat exchanger taking this heat away to ambient. If you have this much liquid flow already, take a hard look at the air cooling side as I believe that will be where your best gains will occur. I don't know what your system looks like, but I'll guess you may gain only 10 or 20% with double liquid flow, but I'll guess that you can gain 90% + with double the air flow. Good luck!

Hurray!!! Someone agrees with me!!

My 1.33GHz@1.46Ghz Athlon has been running on a 60 gph pond pump for the past 4 months. Before that it was hooked to both my furnace K7-500@750 and a celeronII600@900 using the same pump. The water runs 2.5-3 C over ambient and I have never had thermal stability problems with any of the chips.

So.....:rolleyes: i just bougt a 180gph pump from home depot....should i return it back??
i will cool the cpu, gpu and chipset (1.4 TB planing O/C, geforce 2 gts pro 64 and mobo chipset from abit kt7a)

So what should we do to gain the most airflow without losing our hearing?

[VotTak]

Yeah... really... We don't want to have huge airflow... we want it QUIET. So, let's go with something powerfull.
