Finally got a new cable modem after years of paying a cable modem lease. It is Arris' top of the line modem but it runs uncomfortably hot so I measured the unit's temps using an IR temp gun and came out at 60C. The CPU has a heatsink and plenty vents to keep it cool but it relies on the airflow in the room. The area where the unit sits does not have very good airflow so I added a fan to force air into the unit to help with stability and longevity because it's mine now.
The unit has many vent holes on the side but relies on room airflow to keep it cool.
Digged around in the old computer parts bin for a 120mm fan and USB cable. A USB port provides +5VDC so the fan will run at a low, quiet speed vs full speed with 12v from a computer power supply. Cut wires, strip, match red to red, black to black, splice and tape splices. Test for operation. Attach fan using double-sided sticky tape. Fits perfect!
CAUTION FAN like on a truck's fan shroud. All up and running. Unit temps are now 30-33C, way cooler than with no fan.
