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....

Ignoring that chances are that those specs are faked by Antec, no, you won't have any problem. But set them as push-pull instead.

My bad. Fan is set as my rear "pull" fan on my heatsink. The fan in the "push" position is the one that came with my 212 EVO.

I guess specs could be faked, but everyone could fake specs if they really want to so i'm not worried about that. Thanks though...

I have the original 212+ and adding a second fan dropped temps maybe 1-2c so up to you if you feel it will be worth the drop in temp for the increase in noise.

That's very true, but with a second fan you also get redundancy, so that if a fan decides to lock up or burn out on you, your system will still stay cool. ;)

Agreed. And when i need the fans on full power, my headphones drown out the noise anyway.

I think if the fan has a built in controller it would just allow full voltage at the max setting. So, I think changing the voltage from another source (the controller) would work just fine in controlling the fan speed. If it does run at full speed it will probably be loud. Mine is if I turn it up all the way to 2200rpm. I have a similar setup with the 212+ EVO.

P.S. Just a though, I didn't see much of a temp difference between the second fan speed. It seemed as the biggest gain is just having the second fan.

I would so love to know the temp difference you get by adding the new cooler. I have been KINDA looking at the same type of thing.

With my case I have a 120 side fan that blows strait on my cpu. I am thinking with the fan set up I have the new cooler, like the one your looking at won't make that much of a difference.

So if you put it on, and think about it and could let me know the difference in temps, I would appreciate it. Or what temps you run after installing it.

According to speed fan I am running 28 and 30 c. Never saw mine over 50 and that is really pushing it more than I normally do.

Yeah even with a 1ghz OC I idle around 32C. You need to get something like Prime95 in order to really push the CPU to its limits. Are you going to OC that CPU? Or did you just put a cooler on there for other reasons?
