Just teasing....I'm in a mood today.
slater3333uk said:Yeh sounds good. I think an interesting thing to test would be how the deapth of the shroud effects matters and also if push or pull is better cous i think that matter could do with settling
Dual vs Single pass would be very interesting
that's a damn good plan - I have a Lambda Wattbox with 4 adjustable rails on it somewhere...hmmm...I might have to order a mag3 and then a pair of the D4's to cover everything else. thanks for the insight, Cathar.Cathar said:Well if you want to just do testing, then what I use are 2 x Laing D4's in series hooked up to a variable voltage power supply. I can run them at anything from stall voltage (4.8v) all the way up to 16v, which is the limit of my PSU. At 4.8v, together they're about as powerful as the Eheim 1046 (very weak - ~1.5PSI max @ dead head). At 16v, together they're about as powerful as the US spec Iwaki MD40-RZ (very strong - ~20PSI max @ dead head).
Makes it fairly easy to set your flow rate just by turning the voltage knob on the PSU.
Sounds like a plate between the two 120mm fans so their flows don't interact.slater3333uk said:What do you mean by 'Adding a divider plate'?? some kind of baffle within the shroud?
