This thermal controlled version
comes with a 300mm long attached thermistor so you don't need to fiddle around
with a fan controller! Simply mount the thermistor close to a heat sensitive
component and the fan will speed up and down based on the temperature it senses.
note: This fan needs a break-in period of a few days to properly spin
up during a cold start. If the temperature detected on the thermistor probe is
not sufficiently high, the fan will not spin up until the probe warms up. Do not
use with fan controllers to maintain the ideal performance of this fan.
