Looking for pressure drop info

[JoeKamel]

Hey, planning on putting together a new WC setup and basically before I pick my pump, I want to have some good information on how strong of a pump I'd need. Basically, I guess you could say I'm picking my waterblocks, and then picking a pump that fits their requirements.

What I'm looking for then really is pressure drop information on some waterblocks at certain flowrates. I've tried contacting manufacturers, but I haven't gotten any replies in the last 10 business days so I figured I'd ask here.

If anyone has information on the pressure drop of the following blocks (2 gpm / 7.5 Lpm) please let me know:

DTek VGA Block
DD Maze 4 GPU
Swiftech MCW50 GPU Block

DTek NB Cooler
DD ZChip
Swiftech MCW20

Thanks a ton if you guys have any info on these.

BTW: Maybe if someone can get a reference on info like this about blocks, it would make a decent sticky.

Estimates based on overclockers.com datum:

Swiftech MCW20 => 0.55mH2O @ 2 US GPM
Swiftech MCW50 => 0.62mH2O @ 2 US GPM

Don't know about the others...

Look for decent reviews. Like this . While I imagine block manufacturers test (or should test) flow I have never seen any data provided from them.

I saw that review, that's why I didn't ask about any of the blocks in it But yeah, I've tried getting info from the manufacturers and and so far, no luck.
