Minimum Pumping power for this loop?

skreenname · 06-22-2009, 03:29 AM

So for a casemod I'm doing I need a really, really small pump.
And I found some pumps that were smaller than any on computer part sites on some pet/ gardening sites.
But I was wondering what the minimum GPH/LPH would be to puch coolant through a loop with a total length of about 15 inches not counting the blobks, 92mm Radiator, and pump.
The waterblocks would be two of These.
And a Dual pass 92MM radiator.
I thought 280LPH might be too much.

But I'm a newb a watercooling, so please enlighten me.

Afterthought edit:
By 'too much' I mean the water might pass through the radiator too quickly to make effective heat transfer happen.

Have you tried a windshield washer pump? Might be a bit noisy though. Im running a modified Coolermaster Duo Viva that has a pump built into one of the blocks. It flows about 140lph (out of the block), and you can usually get a kit for about $70 on eBay still. Not too many of them around, but even though you may not use the block itself, it runs 1/4" ID tubing. Might be what youre looking for. Maybe you wont need the blocks if you get that?
