Optiplex CPU 80mm fan adapter

thingiverse

Here is an adapter to allow a factory CPU blower fan to be replaced with a standard 80mm fan on a Dell Optiplex 9010. The heatsink appears to be a Dell J50GH heatsink. I'm upgrading this old computer for new purposes and want it to run nearly silently, so I'll be installing Noctua fans using this adapter (not shown). Using M3 x 8mm allen head bolts is recommended, but you can reuse existing bolts if they're still in good condition. Make sure the screws or bolts aren't too long because they can go in too deep and damage the heatsink. Attaching the fan to the adapter requires two to four typical fan mounting screws. There's very little space between the side panel door (when put back on) and the top of the fan, so you may want to drill some holes for better airflow. I haven't tested this setup yet or compared temperatures. Please try at your own risk.
