    • In all of the years that I have worked on this machine, I have found no good way to remove the fan.

    • The best way to start, is to push in here on the side of the fan.

    • Being careful not to exert too much force, try to push in, and wiggle the fan outward as such. (2nd Photo)

    • You can now lift the fan all the way out, and remove it.

    There is no need to pull out the fan. Just take a knife and you can squeeze the tab in step 7

    I wanted to second what Willy said; as far as I can tell one is intended to remove the PSU before the fan. You just jam something the right width in between so the PSU tab is depressed, pull it out, and after the PSU is out removing the fan is easy.
