Hey Guys!

Just wondering how are your fans organized in your U2-UFO ?

I was thinking of setting mine as the 4 front 120mm fans suck air, the 2 on top as exhaust and the 3 on the back as exhaust as well. Should i make the 2 on top suck air ? That would kinda kill the airflow in the case no ?

Thanks!

I would have the top 2 drawing air in as this will help cool motherboard and stuff.

Yeah well, there is quite a lots of dust getting in my cases due to pets and me being lazy to clean the room. So, it would probably put more crap in the case than anything good. Oh well.

While im here...I have a PA120.3 and was wondering if i should put the fans before or after the rad ? "After" meaning that the fans will pull air through the rad from outside and before meaning that they will push air through the case from outside too. I know some will say that there is not any significant performance difference but just wanted to get your thoughts on this.

It's better to have positive air pressure than negative. As for the top fans and the dust problem, u can always put a dust filter. ;)

As for the pull vs push. Pull is a tad better but i don't care since i like seeing my fans rather than the rad... :p:

I have all of the front fans as intake, and the dual 120mm on the back as intake, rest as exhaust.

Well, you guys convinced me. Ill have the 4 front fans sucking fresh air as well as the 2 on top. And all 3 behind pushing air out. As for dust filters check these pics : I mounted some mosquito net behind the fan grills for the dust problem. Im kinda proud it looks great :p:
