Which pump do YOU use?

[Cathar]

A 140W pump eh?

How much hotter do you think your water is getting due to the heat that the pump adds?

I reckon you'd be very surprised if you actually measured it in comparison to a 35W pump like the Mag3.

I cannot ever recommend grabbing a 140W pump. The pump heat will be a greater contributor to the water's temperature than the CPU.

it probably dumps more of the heat into the case than into the water.... at least if it is true that it is insulated from the liquid.

I have not tried the new design on the quiet one pumps as of yet but the RLQO design like the one that I use adds very little to the water temp -- it is rated at 87w which is one hell of a lot less than the 140w of the new QO6000.

The RLQO switches on and off with the rest of the system so there is always air running thru the heatercore to maintain watertemps when the pump is on.

to put it into perspective, this is the rest of the system:
waterblock (weapon block rev 1.2):

chipset block....damn, no pics as of yet. 1/2" fittings, 80w pelt, cut to fit the clearance area around the n.bridge on the nf7. I brazed it shut with 15% silver brazing rods like the one in the above pic...they were left over from a phase change system I was building so I thought they would be able to handle the minor pressures associated with H2O cooling with no probs.

heatercore:
'79 bonneville core with 1/2" fitting swapout and the shroud I built for it - you can't see it in the pic, but it has some dividers under the shroud to split up the airflow that comes thru the core.

as for the mag3, I have used much lower rated pumps before. The Danners I have tried had impeller housings that were PsOS. They leaked regardless of the tension on the housing screws or the amount of sealant dumped on the o-rings. Eventually, they cracked or the motor went tits-up. that has been a while back and they seem to have fixed the problems but no more danner md's for me.

as far as temps go, the current system with the RLQO is performing considerably better than the same loop with pumps ranging from 300-750gph (not including the current one which is rated as 1140gph). the previous ones I tried included an LT (not bad for a cheapee), a dolphin (really liked this one), an Iwaki (also very good), the danners, etc. Pentair used to claim that the RLQO dumped a very small amount of heat into the water as compared to other pumps in the same GPH range - in my experience with them I have found that to be a fairly accurate statement.
