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.
