high fpi rad and shroud

post #1 of 3
Thread Starter 
hi all,

i'm about to add 12 x gentle typhoon ap-15 (1850 rpm max) to a big external rad with high fpi(about 25),35 mm thick,
in a push only configuration.
i've read martin's article about the importance of shrouds,
but in that scenario he was using a rad "21mm thickness with approximately a 13.0 FPI fin density",


do i need to put a shroud or not?

Shrouds always help. They remove dead spots from the fan rotor, the big issue is clearence. Mostly internal rads cant support shrouds

i've just read the second part of his article:

http://martinsliquidlab.org/2012/01/15/radiator-shroud-testing-v2/

"Shroud benefits are very much radiator specific".

also,
in certain situations it even seems that "shrouds on some radiators in the right conditions can even hurt performance".
