these are wat im using seem to work good
Yate Loon 120mm High Speed Silent Case Fan - D12SH-12 - Stock $3.95 - Sleeved $6.95
...you can get them with or without sleeving in your choice of color for $6.95 each or you can get them w/o sleeves for $3.00 off per.
Their 140mm fans are going in the new AX series PSUs'. That's how good they are. And you can get them in Red or Blue if you want LED fans to take the place of CCLs' so you don't have to have the little blue boxes to hide.
Oh and largely it depends on your Case. If you already have a lot of air flow (like 932 owners do) then exhaust is fine. But if you only have a limited number of 120mm fans to intake with then you'll use it in an intake role. Though some owners do intake in the 932 as well.
I notice that the corsair push/pull blog suggests buying a pair of 50CFM max airflow fans. And that those you linked have 74.48 and 88.
Is there a benefit?
Also, speaking of the 932, I'm looking for a case with the best airflow since I'm not going to do water cooling beyond H50. Is that and the upcoming HAF-X the best?
