Okay, I'm stupid! I forgot to write down which direction the fan was
moving air when I removed the defective fan. It looks like the H7861
has two fans one of which sucks air in and the other blows it out. Is
that correct? Or do they both suck air in? The one I'm replacing is
the one that is mounted at an angle. The one I haven't touched is
setup to suck air into the box. How should I mount the diagonal fan?
To suck air in or out?
