swifty_morgan :
are you trying to tell me it'll fit in a hole that's too small to accommodate it?
Absolutely not, what I'm trying to tell you is that it will fit perfect, I'll make my point clearer:
The measures of the H80i are: 120mm (width) 152mm (height) and 38mm (thickness); the additional 32mm of the
total height comes from the water bay and it's oriented to the longitudinal axis of the radiator and the case, ergo, when installed it won't be bigger than the rear fan mesh because its widths are equal; and as I said in my earlier post, the heat dissipation panel is 120x120mm, so the height of the panel is the same than the mesh, and that means that the panel fits perfectly on the mesh, and of course, the water bay of the radiator will be out of the rear fan mesh area but that doesn't affect performance
Don't you think that if the panel were really bigger than the 120mm mesh the manufacturer would specify it somewhere, and would not bundle a 120mm fan?.
As a side note, I'm building a design/gaming rig using a cooler master storm scout 2 and had the same dilemma, but a quick look at the specs and with some logic, it turns out to be just fine.
