====== Adaptec HBA Notes ======

===== ASR-71605 =====

  * The AFM-700 BBU cache module can be removed completely without affecting card operation e.g. in HBA mode; I removed it to improve airflow
  * Heatsink has M3 threaded holes spaced for 40mm fans
    * Screw/bolt length: (thickness of fan) + (thickness of heatsink = 10mm)
    * Do **NOT** exceed the length above by more than 1-2mm, the excess length will hit the PCB, damaging the PCB and lifting the heatsink off the controller die
  * Card gets very hot, hence Adaptec's requirement for 200 LFM of airflow. Don't worry too much, the card will emit a continuous and loud alarm if it's overheating
  * The binary arcconf packages from Adaptec/Microchip don't work with the mainline Linux aacraid driver
