RAM-33 Pressure Drop

Postby Sleepdep247 » Wed Oct 07, 2009 9:03 pm

I'm looking for the PSI impact these blocks will have on a loop in this configuration:

While we have not posted the flow curves for RAM-33 yet, they are roughly similar to a chipset cooler with 6mm nozzles. It is a limitation of the width provided between DIMM slots on most motherboards. However, the RAM-33 is a bit less restrictive than the RAM-35.

For a 10-13mm ID system with moderate flow (4L/min+), we would recommend splitting RAM-33 into parallel (smaller ID) paths when there is more than 2 in the loop.

Thanks for the info, can this be added to the RAM-33 page? Also by the way, I still do not see the flow rates for the RAM-33 yet.

But running the PMP-450 @ 24V we can push 18.9L/min at max and 13mm ID tubing, so what would that translate to a 4, 6, 8, and 12 configuration/limitations be?

So should we push the 13mm into two or three 6mm ID paths? With the ideal of making the 6mm paths nearly the same length to keep the flow the same through them?

There will be posts about this elsewhere but 3x6mm hosing is ~= to 1x10mm hosing for throughput. So in theory a 13mm hose could split to 4x6mm hoses but clearances would start being an issue unless you used regular barbs instead the of the superior compression barbs. The more you optimize for flow in this situation the more hoses and crowed it is going to get.
