Although it technically isn't a SFF case, I'd figure someone here may be able to help me out. I have the TU150 and this really is a great case but I'm wondering if temps can be improved if I were to add another fan above the cooler. My temps are pretty decent at 70* under load but lower temps are always better, right? I know I'd have to drill some holes in the both the top section and cover but I'm ok with that. I'm thinking about trying to add either a 92mm or 120mm as I really don't need the handle. Should this fan be intake or exhaust? Any advice would be appreciated. Thanks.
