What pump to buy?

Arcturius · 09-03-2001, 10:39 PM

I'm setting up my first WC system, and I'm trying to decide which pump to buy. I'm trying to decide between:
<ul>[*]a cheapo looking 158GPH (Max) submersible -- $17[*]165GPH MagDrive -- $17[*]79GPH Eheim 1046 -- $46[*]158GPH Eheim 1048 -- $60[*]250GPH MagDrive -- $34[/list]
Planned blocks:
<ul>[*]Either a single channel hand-made maze-ish block or a converted heatsink for the CPU (Tbird 700, currently).[*]single channel handmade or (more likely) converted vidcard or northbridge sink for vidcard (don't want to take up more than 1 PCI slot)[*]single channel handmade or converted socket7 sink for northbridge[/list]
Planned radiator:
six-pass 3/8" id transmission cooler, if I can get it. I want to split the 1/2" id hose into three 3/8" id lines to slow the coolant through the rad, then join them again on the other side and speed the coolant back up.

Pump:
This is where I need help. I intend to run it in a resivoir made of an underground electrical junction box.

Planned layout:
Hot coolant leaves pump, goes into rad. Cooler coolant leaves rad, splits into CPU and NB/GPU lines; NB & GPU in series, NB first, GPU second. Coolant is recombined from CPU and GPU, going back into res. I will either mount my rad high in the case (I've got lots of room in the top of my Apex full tower) with a T and a short piece of hose higher to catch air, or mount it low in the front of the case so the air collects in the res.

What do you guys think?

I don't think any of those pumps are ideal for 3 waterblocks. I'd pay the extra $8 and get the Eheim 1250 myself.

Oh wait I did.

I also recommend installing t's or y's for those lines, for obvious reasons. that should help eliminate some of the weaknesses of whatever pump you get.

I have a settup simular to this, but with 2 gpu blocks linked for a voodoo 5. (this still includes the block for the northgate) I have the magdrive that pushes 500 gph and it will shoot water out of the system. I totaly suggest that. Also, go with "y" joints, much better for the flow they give
