PANO-MOUNTS 140mm Quiet High Performance 3pin 4pin Molex Connector 12V DC Computer PC CPU Case Fan 1000RPM 2-Pack

Does what it says, not much to say. The only thing is if you want to hook them up in series you have to use the connector that only has 2 leads in it. I believe the 3rd (yellow) lead is for speed control. So you can hook one up with the 3 lead connector to the motherboard but if you are out of case fan ports (which I was) you have to get power from the first fan and then you can only use the 2 lead connector. So the second fan's speed will be static.

Not suitable for direct cooling of computer components. Excellent for indirect computer case cooling. Max rpm is 1000 vs 1500 to1800 rpm for other computer fans.I am using mine to provide cooling to a custom-built DIY hydroponic LED grow light fixture.

J'avais besoin d'un ventilateur 12V pour une application autre qu'un refroidissement de PC , Très silencieux et le nombre d'ailette permet un bon flu d'air a base vitesse. Les pièces d'installation comprise avec les ventilateurs complètent bien l'ensemble.

My computer was running on 5 fans and I wanted a strong exhaust fan with 2000 + rpm.This fan will strongly move the air out. It might be loud of high RPM but i love it

Replaced 3pin fan with these and have much better results than I did for cooling. Lots more airflow and control.
