Fan bridging

Hello experts, I just wanna know that is there any bad effects bridging a fan so that it moves all the time when you switch the ignition on?

Not anything major, but if its the engine cooling fan the engine will be over cooled.

If you set the fan to max speed it can be a bit loud.

More energy is used but you probably won't notice that.

Its a great way to 'get you home' and keep the car running after a cooling fault.

If its the cabin fan, it would just get annoying if the fan wouldn't turn off and that can get a bit loud on max, but not cause any other problems

Thanks it's engen fan but it doesn't make annoying noise because there is nowhere it touching.
