im choosing fans for a radiator and when im looking around not all fans have mm-h2o in there description is there anything else i can look at to work out if the fan is going to be good for a high fin array radiator.

This was just posted on the forums? http://forum.overclo...w-corsair-fans/
and generally you can look at the blade layout to give you an estimate.
high pitched fans (more strait up and down and shorter) move more air have less static pressure.
Long flatter fans generally have more force to them...
Its kinda like tires on the road, the more surface area they have the more grip they have.

Noctua NF-F12s or Sycthe Gentle typhoon (1850 rpm) are very popular and excellent for radiators.

i haven't purchased any of the parts yet im deciding on all the parts and im trying to chose some fans and looking for a mm-h2o above 2.0 but not all fans have it in the description and was wondering if i could look at anything else like cfm or rpm to figure out if it will be good for a radiator.
i was thinking that the CFM might have a link to the mm-h2o but didnt know how high it had o be to go over 2.0 mm-h2o

Most CFM measurements are taken in an unobstructed test... like i said, look at the pitch of it, and you can make up a little math equation.
Take the RPM divide it by CFM and the higher the remaining number is a generalization of how much pressure it can generate without a real unit.
There is no real equation from just having those numbers but it can give you a general idea.
Edit: Don't let this equation 100% influence your desision... as my delta fan can push 250 CFM at 5000 RPM and it has a huge amount of static pressure... going by that equation compared to other fans it would have almost none.
