Clicking sound as it revolves

could be a faulty start/run capacitor
regardless of the ambient temp , it should not suffer any adverse effects from the temp

I had this noise and found that the fan shroud was being hit by the fan. Renoved the fan shroud and the noise stopped. The shroud had broken into two pieces.

The clicking is generally caused by a flat roller bearing. If the sound seems to be from the fan clutch you can grab the fan blades and see if the bearing is worn by rocking the blade by pulling it towards you and rockng it away from you
Another way to see if its bad is to use a solid pole something like a broom handle. Place one end of the handle on the accessory that runs off the serpentine belt such as the alternator and place your ear on the other end of the handle. As the engine runs you can hear a bearing making noise revolving as it move. If a bearing is bad the noise will be much louder and have a heavy grinding noise

Sounds like gear and chain need to be replaced in transfer case.
The popping and or clicking is the chain trying to climb up over the teeth on the gear in transfer case.

I know that some fans can be oiled. You may want to look into that for your particular fan.

We have the same tapping sound on our 2003 Envoy six cylinder engine. I believe the sound is coming from the radiator fan clutch assembly. When the engine reaches its operating temperature and the fan clutch engages, the tapping sound goes away.

remove rear blower motor and check for debris... possible replacement necessary

sounds like surge shorting
call in an electrician to check the installation of the unit

PATTI-- THIS CEILING FAN IS AT MY DAUGHTERS HOME IN RENO--WE LIVE ABOUT 50 MILES FROM HER SO WE HAVEN'T BEEN IN YET TO TRY REMOVING THE GLOBE--PERHAPS WE WON'T BE ABLE TO REMOVE IT EVEN WITH THE INSTRUCTIONS IF YOU ARE HAVING THAT PROBLEM. IF YOU FIND A WAY TO REMOVE IT, PLEASE LET ME KNOW. WHEN WE GET IN TO RENO I'LL LET YOU KNOW IF I AM ABLE TO REMOVE IT.

The fan should be replaced. The bearings are getting worn out.
