sorry... maybe i need more coffee... but i don't get it...
you're pulling air from your rad? then from the size, i take it that your rad is 140mm and you're using 120mm fans hence the reduction in size?

No those are noctua 140mm fans, fan shroud prevents blind spots on radiator so its beeing more effective when all radiator gets air sucked through it

It looks ghetto from inside but it should work very nicely :)

hahaha... i know about skinnee's tests...
my comment was referring to the size of the fans and shrouds.
from a certain angle, it did seem as if OP was reducing 140mm to 120mm...
hence my question...

As Blueking stated already, it's a mdf board.
Blueking, what's the thickness of that board? And what tools did you use to cut it?

28 mm mdf, used jigsaw didn't have a circular hole cutter at this size, then rest were done with knife , file (tool) and wood rasp

Looks good, but I think it is not deep enough. If you can find Martinm210's testing, he had an optimal depth. I can't remember how deep he said to make the shroud, but it was at least 38mm or more, as far as I can remember.

Depends firstly on the type of fan (25 or 38mm), and secondly on the configuration (push or pull).
With 38mm-push, 28mm is the optimal size for a shroud. However Blueking seems to be pulling.
Also, although I couldn't find a graph for 25mm fans, I'm fairly sure there's a difference.

I did choose pull because of fans beeing on backside of radiator against wall, in front jusr radiators will be visible when see into 'windtunell', any way it's better than none shrouds at all ;)

Fans will work best with an optimal depth. More than xx and it doesn't help anymore. In Martins tests he said 30mm. But he didn't test with many different depths either. It was more of a study of push/pull and using a shroud.
OP: That shroud is awesome! Very nice work. It'll help a bit on noise and a small increase in cooling.
Martin said 10 to 16% increase in cooling in his specific application. If your DT is 10C, you could get up to 1.6C decrease in your DT. If your DT is 5C, then thats a lot of trouble for a small temp gain. This is XS though, every bit matters and tinkering to make that is better than many other activites.
Nice shroud!

Some really nice testing and results. Are you going to paint the unit :)?
