Compatibility and installation
- Use the manual for the exact Mini model; standard Peerless Assassin hardware and dimensions are not interchangeable.
- Confirm case-height allowance and fan/DIMM clearance for the actual fan position; do not infer compatibility from heatsink height alone.
- Connect fan to a rated 4-pin PWM header and confirm tach feedback after assembly.
Service notes
Power off and hold the fan stationary during cleaning. Reapply thermal compound after lifting the heatsink; inspect socket hardware and fan clips before reinstalling.
