what motherboard do you have? I have a MSI Z77 GD55 and a hyper 212+ and it barely fits because of the ram. the ram slot closest to the CPU is actually being bent slightly by the fan, not enough to break the ram or the slot though. I tried pointing the fan upwards by this is even worse and wont fit at all. I have corsair vengeance ram though, it might clear normal ram. the hyper 212+ is awesome, but make sure it will fit. if you aren't sure ask me.
