CPU 120mm Fan Question

[ManusDei]

So for my case i bought a 120mm fan for side cooling. But i decided to go with a 200mm side cooling fan that is compatible with my case instead so i had the 120mm to play around with. The fan is an Antec 120mm Red LED Case Fan (Specs for the 120mm Antec listed below).

My question is, can i use this on my Cooling Master Hyper 212 EVO as a 2nd "push" fan. The EVO comes with adapters so that i can just slide it over the heatsink just like the fan that was included with the EVO. I plan on running it using my NZXT Sentry Mesh fan controller and leaving it set on the highest speed setting on the adjustable slider included with the Antec. Will using this Antec "Case" fan present any problems (i cant think of any, but it is listed as a "case" fan and is LED so i just want to make sure)? Thanks for any help in advance....

I don't see why it could cause any problem.

Just make sure you've properly install it on the heatsink and connect it to a fan header.

That’s an Antec tri-cool fan. It’ll work fine, though the LED may possibly dim if the fan controller reduces fan speed by reducing the voltage.

I have noticed that when i turn down the fan speed on my controller it dims the LED. Not too worried about that though. Glad to hear its not a problem. Felt kind of ridiculous posting this, because i couldn't think of any real reason the fan wouldn't work, but just wanted to make sure. Thanks for the replies....

Like the famous saying, measure twice cut once...

Best to be knowledgable before making the purchase

Actually, I think it might be a problem if I am understanding your situation.

The EVO comes with one push fan and one pull fan already for >fan>HS>fan> and if I understand you are adding the case fan to also push, so you have >fan>fan>HS>fan> with two fans back to back pushing. If that is the case, the airflow from the first fan will affect the airflow into the second fan in line causing it to spin irregularly and the rear exhaust fan will have more airflow into it than it currently exhausts which would also cause it to spin irregularly. The EVO design works because there is equal air in as there is out, adding a 3rd fan could cause irregular blade spins and greatly reduced fan life.

The EVO instructions discuss installing a push/pull configuration and does not discourage this. I am not sure that it would truly affect fan life to the extent i should be concerned with it. And if so, i will take several degrees cooler versus some reduced fan life (they are cheap anyways, processors and other components aren't).
