Can I put a second fan from another brand in my cpu air cooler?

So here is the thing:

 

Right now I have a cpu air cooler Aerocool Verkho 5 and I am planning to change it for a Scythe Mugen 5 rev. b. It comes with a fan and I am wondering, can I attach the fan that comes with the Verkho 5 to the Mugen 5 as a second fan?

 

This are the specs of the Verkho fan:

 

Fan: 120 x 120 x 25 mm
Power consumption 3.12W
Speed: 800-2000 RPM
CFM: 27.2-56.4 CFM
Noise(dBA) 15-27 dBA
Connector PWM- 4pin

 

This are the specs of the Mugen 5 fan:

 

Fan: 120mm x 120mm 27mm
Speed: 300 – 1.300 RPM ± 10%
Noise: 4-24 ~ dBA
CFM: 51.17 CFM ± 10%

Connector PWM- 4pin

You can, but both fans should provide the same kind of airflow, so one fan doesn't speed up/slow down the other. Not sure if it's worth it in terms of amount of cooling that'll provide.

Im not sure how fan mounting works on your air cooler but if you have the ability to mount a second 120mm fan either by whats provided with cpu cooler or diy with something like zipties than yes you can mount any type of fan you would like so long as its the right size (right size being the size of the fan it came with)

Yes you can, if they are both PWM and have similar RPM

I updated the post with the spec of both fans.

I wouldn't mix those, because RPM and CFM is different. That means the fan with higher airflow will either push against the other fan, speeding it up, or the slower fan may starve the other for air, slowing it down. That's going to introduce additional noise and may have negative effects on cooling performance.

I understand. Well, I won't mix them then. Thank you very much.

just give it a go. take some measurements. see what happens.
