>no heatsink/fan<p>CPU can take some quite industrial range (125C? I know I've seen a number somewhere...), and will throttle starting at 85C. In practice, it will get to 75C in long compiling sessions. Thus, it doesn't really need a heatsink.<p>However, you might want to install a m.2 nvme, in which case you'll definitely want that heatsink as you'll have more heat. I went with XU4Q's (from ODROID), which is a passive solution, a tall heatsink. It fits in place w/o issue and doesn't disturb m.2. CPU tops out at around 57C now.<p>I notice that, in the pictures, the reviewer did not install the 4x spacers that shipped with the board. This board will not sit evenly on a desk, as the m.2 slot protrudes; it might interfer with cooling. That'd explain 90C where I got 75C.
