The existing heatsink is pretty hot under basic Windows 10 load and I'm not convinced it's secured on well with those spring things that go in the PCB holes. I am looking to hack up the provided heatsink. Before I do, does anyone know where I can get another as backup? What I really want is a slightly wider and shorter heatsink. Maybe if it's low enough, I could put a slim 40 mm fan on it. I figure I'll secure it with thermal tape or screw it down to those 2 holes with nylon bolts.
