WD40 - Nooooo! It gets gummy. Use a proper lubricating oil. Or replace the fan.
"Pro tip:" Do not direct the output of a strong air stream (e.g. the kind used for automotive work) at the fan as it can de-blade the fan.
- hutzlibu 3y agoGood to know, but in those few fans I used it for, it worked so far ..
- BizarroLand 3y agoAnd if you do that anyway, don't be a dingus. Disconnect the fan cable from the socket so that the motor doesn't send pulses of energy back into your laptop. It probably won't harm it, but better safe than sorry.
- malfist 3y agoMotors have flyback diodes. Otherwise they'd burn out things every time they turn off
- BizarroLand 3y agoNot in most laptops they don't. https://forum.arduino.cc/t/is-a-flyback-diode-built-into-laptop-fans/932322 https://forum.arduino.cc/t/is-a-flyback-diode-built-into-lap... "You will find those fans are brushless DC fans, they are controlled by an inbuilt driver circuit and as such do not need a flyback diode."
- malfist 3y agoSo you "disprove" my statement with some rando on the Arduino message board that has less than 20 posts in their lifetime? What makes you think they're an authority? Brushless motor still have fly back voltage that has to be clamped. You may not need to install a diode in the fan, but I can guarantee you that this "inbuilt driver circuit" has such a diode. And if you read the linked thread a bit more you'd see where they test it and it does produce -100V at shutdown. If there wasn't a flyback diodes it'd be burning out ic's left and right
- BizarroLand 3y agoWhy would I accept your word without any backup? Its on you to provide evidence of your claim, not on me to disprove your unfounded claim.
