Those fans don't provide any specs. But just by their size, I'd guess they're probably not going to pull enough air.

i have the same but in a 3 fan version. Approx 12cfm total for the 3 fan version.

Small fans in general are a bad idea.

They're capable of much more irritating high-RPMs, and they need to run at them in order to pull even a tiny amount of air.

Stick a 120mm fan in place of this, run it at 7V, and it will pull five times the air with much less noise.
