 +==== Cooling ====
 +The HackberryPi CM5 ships with a passive heatsink. It should be adequate for most usage. Temperatures will go up to 70°C, which shouldn't be a problem. 
 +
 +However, you can install an active cooler with a fan (like [[https://a.co/d/grKWdSR|this one]]). The only requirement is how it mounts to the CM5. The underside of the heatsink should be flush. No stand-offs should be included (they can be removed, with a Dremel if needed). \\ 
 +The following parameters [[os#editing_config.txt|can be added to the ''config.txt'']] to set a fan speed curve:
 +<code>
 +# Fan is cutting on at 40 degrees Celsius,
 +# it is going to drop it by 10 degrees at a fan speed of 200
 +# temp=millicelsius
 +
 +dtparam=fan_temp0=40000
 +dtparam=fan_temp0_hyst=10000
 +dtparam=fan_temp0_speed=200
 +
 +dtparam=fan_temp1=50000
 +dtparam=fan_temp1_hyst=20000
 +dtparam=fan_temp1_speed=225
 +</code>
 +Thanks to Discord user [[https://discord.com/channels/1158055950280826922/1298664686002241648/1379656689145352352|Tripp]] for the parameters!
