Thanks for clearing that up.
2 pumps in a row, will be quite a line-up
Will the 2 L20 have a better performence that one L30? (or an emheim 1250)
L20 - 1.85m 700L
L30/emheim 2.5m 1200L
As I have 3 rad's, I'm thining about building a seperate box for the rads, and place the computer on top.
It must be possible to fit the pumps in there.
I found out (and was reading about it in forums) that sandwich a radiator gives the best performence. 2 fans on one side won't work as good as a sandwch. Don't know why, but that's how it is. (lower water temps)
The box will have a front of 2x 12cm and 3 8cm fans.
The rads will have a 12cm fan sucking out the air. All running at 7v, to keep the noise down.
Nice hobby... water cooling
