Do fans need to be identical for push and pull?

PCnooberson · Dec 5, 2013

I have a radiator, and 2 fans are currently pushing air through, but I was hoping to soon add 2 more fans to pull air out. My question is, do the fans that are pushing need to be the same as the fans that are pulling. Reason for this is that i want to use Noctua fans to pull (great quality) but buying 4 is rather expensive.

Is it alright if the fans that are pushing are a different manufacture? What if they have different RPM? CFM?

IMO, it's best to have the same type of fan for push/pull configuration.
Slow fan can't push air fast enough for faster pull fan to pull air.
Fast push fan push too much air and slow pull fan can't keep up.
Why Noctua? They're expensive.
Here it comes in pretty colors!

Those were my first choice, but a large majority of those reviews talked about alot of failures, especially with rpm
