Today for review I've got a pair of new fans from Noctua, they're called the NF-P14 FLX fans. They're 140mm fans making them fairly large of course, these 140mm fans are special in that they have round frames. The round frames make the fan essentially smaller, or at least the frame is smaller. The mounting holes in the frame will fit where any 120mm fan will fit, thus the end user can easily replace a 120mm fan with a 140mm fan for even more cooling ability. You can use the NF-P14 though in a 140mm space since Noctua has included adapters to help you do this. So read on to learn more...
