Skinnee Labs - GTX480 Block Round-Up (working thread)

... but is the flow rate for just the VGA block itself or a full system with rad, res etc?

That would be just the block and pump. You're going to have additional restriction in your loop with a radiator, tubing and so on... but blocks are the most restrictive component in your loop.

For instance, The PQ chart shows the EK block at 2.5GPM with a D5-S5/EK V2 Top, but our loop flow rate for our test loop was 1.74GPM with radiator, tubing, and QDC's. Each component brings restriction to the loop.

Oh yeah, and we used a DDC3.2 for the test loop, not a D5.

It's nice to know that the blocks are the most restrictive component because some of those blocks are quite restrictive, makes me rethink my purchase of my 4x120 GTX480 radiator being on the restrictive side!
