That's very true. It's not a huge job to switch around the fans. I will switch out the top fans to intake and see how it goes.
Sometimes just preparing to make a change in the PC takes time -- unplugging components, gathering tools, clearing a work space, taking apart the case, etc. At least for me it does since I'm quite deliberate and still new to PC building/modifying.
Right now, because I have a couple of new components (AIO, 16 more gigs of RAM, a 3rd NoPro + expansion LED kit) to install, I'm going to wait until I have everything ready and then set aside a couple of hours to install all the upgrades at once.
