If you mount a 360 mm rad up front like the H150I PRO as i'm doing literally right now. So if you had planned on running 2 fans up top like I did for exhaust, they will not fit as the rad lines get in the way. 1 fan will fit on the top mount towards the rear of the case. However, I found a work around. You can install 2 fans on top of the mounting bracket. Basically they would sit between the glass and the top of the case But.... The top dust filter will not fit back on if you do that. For fun, I placed the top dust filter below the mounting bracket from inside the case and since it's magnetic it does sit there. Not perfectly but it stays. So I may do that or not use the top filter or just use 1 fan mounted normally. I'm not sure yet.
