Does cooling affect stringing?
Cooling reduces the level of adhesion to the bed surface, so the fan should not be used while the first few layers of the item are built up. When used correctly, a fan will reduce stringing, thus helping you achieve a cleaner, more appealing final product.

Why does my car a / C fan stop working?
The issue may stem from a malfunctioning cooling fan relay, wiring, or the fan itself. If the A/C Condenser fan isn’t working the A/C may stop cooling when the vehicle is in traffic and the “pop off” valve on the compressor may release the excessive high pressure due to elevated temperatures, making a loud noise and some mist from under the hood.
Why does my cooling fan relay stop working?
Cooling fan relays can stop working for any number of reasons. Common causes for relays failing to operate might be: Failure of the computer, temperature switch, or relay control module that turns the relay on or off. Ants in the relays (more common than you’d expect).
What causes a fan to run all the time?
Watch for changes. An electrical open circuit in the relay coil can allow relay contacts to remain in their open position and never close. A shorted control circuit or stuck relay contacts can continue to deliver power, keeping the fans running continuously. Obviously, if the fans run all the time, they will drain the battery.
Why do I need a cooling fan on my printer?
What that value is for your printer is left as an experiment. Several test/calibration print designs exist (e.g. for bridging) to test this out. It is said that a little cooling aids in better aesthetic prints (finer details) while less cooling results in stronger layer adhesion and thus stronger prints.
