My System Specs

Default

Like lowfat stated... rads are not that restrictive. They only technically do 2x 90* turns the piping inside the fins is pretty much laminar flow. Blocks on the other hand vary greatly on flow restrictions.

It would be nice if the IPT handbook included these kinds of fittings so guys could calculate total restrictions etc. That won't happen anytime soon though. Perhaps someone in the computer cooling industry will step up and make a handbook so we can correctly calculate and spec pumps speeds based on those numbers.

GPU blocks are basically globe valves imo if you can figure out how restrictive an elbow is an approximate number could be figured out for the blocks. In the end less 90 degree turns are better. I would think with as many blocks and rads as the fella above dual loops might produce lower temps.
