Hey all, was hoping to get some feedback on how to optimize the cooling in my system. Sorry if I get so specific, just trying to paint a good picture of my system for the best feedback!

I bought a Rosewill Blackhawk case this month for my new rig. It comes with 5 stock fans: 2x 120mm front fans (4 pin molex), 1x 120mm side fan (4 pin molex), 1x 120mm on the top of the rear panel (3 pin), and 1x 140mm fan on the back of the top panel (4 pin molex). I also have an extra 120mm fan on hand for a total of 5x 120mm and 1x 140mm fan (not including the 120mm fan on the heatsink).

I'm using a 212 CoolerMaster Hyper Evo heatsink, which comes with 1x 120mm fan that I have mounted on the heatsink to blow air in to the the sink as opposed to pull air through.

Because of the size of my heatsink, I had to move the side 120mm fan to the middle of the bottom panel of my case as an intake fan in order to close the case up. I also took my extra 120mm fan and added it to the top of the front panel of my case above the other two (right below my optical drive)

My main question is:
It appears my top 140mm fan positioned on the rear of the top panel is acting as an intake fan as opposed to exhaust. The 120mm fan near the top of the rear panel is acting as exhaust. This is the orientation the 140mm fan came in, however, so it makes me think maybe it was by design. Shouldnt the two fans in the top rear corner of my case both be exhaust? Why would the top fan be intake in the very back of the case?

Bonus questions:
Are the current positions of my fans optimal?
Should I get a smaller fan that fits for my side panel or is it going to hurt more than help anyway?
The 120mm fan on my heatsink should push air in and not pull it through, correct? Pulling air through seems like it wouldn't be as powerful, and pushing setup takes advantage of extra space better.
Any other suggested improvements?

Any feedback would be appreciated!

You can try this: http://www.pccasegear.com/index.php?main_page=product_info&products_id=24236&cPath=1344
Fan controller is one option. You have too much fans in that case and rpm is too high. .
Id do it like this.two top fans 120 or 140mm one bottom (slow > 1000rpm) ad one front fan. (slow)
Side gan needs to be slow if you use one. Back fan can be warm adjustable 600-1200rpm.
That case do no keep any noise inside so fast fan make it sond like jet engine. If you do not make fans worl lower rpm.
Maybe fan controller is best. I do NOT know if this is any good:

hey, i'm actually building my own system with the Rosewill Blackhawk (didn't buy it yet though) and also going to install the hyper 212 evo/plus cpu cooler. I read your post and here's what i was thinking of doing, maybe this will help: Reverse the top fan from an intake to an exhaust position, leave the other top space without a fan. This site has done a study on airflow and according to it you should leave the other top fan spot open but without a fan, as the air it will pull/exhaust will conflict with front intakes.

What i plan on doing is using only the top drive slot, and removing the brackets for the other 3 to replace with yet another 120mm front intake so it from the front bottom to top looks like this: fan1, fan2, fan3, optical drive. This third fan, make it an intake ofcourse, and it will create a straight line almost perfectly aligned that goes like this:
rear exhaust<hyper pull fan<hyper grid<hyper push (stock) fan<front intake.

So the CPU will be nice and cool permanently, my only concern is how the top exhaust will affect the airflow. I DO know that its 100% best to make the big top an exhaust, again, based on that website.

So that's all the contribution i can offer, if your current setup works fine can u update this post with your observations please? i want to learn more about my options with this very nice case.
