The fan seems to run on even when the processor is idle

The fan and processor are not tied directly to eachother. The fan is responding to the temp of the processor. The 2 most likely things here are, the processor stays hot, so the fan keeps running, or the fan is malfunctioning and staying on. If it is just the fan, that is a very inexpensive part. If it is the processor overheating, you can elevate the bottom of the laptop when using which will let air below it and cool it slightly. Other than that, you can buy a spall plastic pad like gadget that is a fan. Your laptop sits on top of it and it plugs into a usb socket on the laptop. This blows cool air up into the bottom of the laptop keeping your processor and other parts cooler, causing it to run more efficient. Good luck.

Cooling fan continues running after car is not running

Its supposed to,, unless it just stays running,, on newer cars the temp fan will run even with the car off, and can start while the car is parked too, if it runs on and on and sucks the life out of your battery , then a stuck fan switch (usually near the radiator) can cause this problem if the fan stays running a long time

I turn my car off and take the keys out but the fan keeps running?

if the car is warm the fans are designed to continue to run untill temp drops to normal temp and then fans shut off. This is a normal operation of the fan nothing to worry about. Now if they stay running for more than 10 minutes you have a problem.

My honeywell Thermostat reaches the heating temp. but the fan will not stop running.And yes the fan is set to auto.It just keeps running and running and running.It stays the same temp but will not shut off...

I want to give a simple explanation before I go any further. On the heating side of a unit even though tthe temp has satisfied the thermostat, the fan will run until it cools down the plenum where the air flows from the air handler. There is a bimetal switch called a fan limit that operates the blower when the plenum reaches the temp set on the fan limit switch. Now if your fan keeps running even after the plenum chamber has cooled down, then you could have a fan limit switch that is stuck in the run position and must be replaced in order to correct the problem.

Thanks for using FixYa.

Your problem is a simple, you have a busted thermoswitch. The thermoswitch is a sensor that engages the fan to get the engine to stay on normal operating temperatures. If the its too cold, the fan should get shut off if its to hot the fan should keep running. If the thermoswitch dies, the fan could either keep running or not run at all. Have the thermoswitch replaced. It's just a 15 minute job for a seasoned mechanic.

I hope this helps. Thanks and good day.

Radiator Fan Stays On

A simple test would involve disconnecting the fan switch while the fan is on. If the fan then stops the switch has failed. If the fan continues to run remove the relay , if the fan then stops the relay has failed.
Various inputs/outputs at the relay should be confirmed to be 100% certain something strange isn't going on.
Above all be careful of the fan itself , if it's running obviously but if it's not it could start during repair

Did you just install this or has it been running for a while.
Usually if the fan keeps running and if you just installed it,the temperature settings need to be adjusted, but first make sure the fan switch button (should be the white button) is pulled out completely.
Set your Fan on setting at about 120°F and fan off at about 90°F.
If you get your fan settings to close together when the blower starts it may cycle on and off a few times before finally staying on.
If this has been in service for a while then it's probably bad and needs replaced.
To check it out first make sure the fan switch button is pulled completely out then turn the fan on setting up and see if it will shut off,if it doesn't then it's bad and needs replaced.

Broken fan on compaq

don't keep running it until you replace the fan. Look for one on ebay or around the web. It is shutting down because of heat. A $20 fan could cost you your whole laptop if you keep running it.

The fan keeps running after the car is off.

the fan is electric and if the car is hot the fan will stay on to cool the engine it should shot off in less than five minutes.

New Hampton Bay Ceiling fan - runs only in clockwise direction

By using the "switch" to change direction I assume you mean the small slide switch on the side of the fan housing. What you have done is correct and would not affect this switch. The switch is probably bad and you need to return the fan. Suggestion: if the switch is on the housing of the light kit and the light kit connects to the fan with a plug, you are in luck. Go get another fan, swap the light kits and return the fan. Saves you a lot of work. Good luck!
