The fan in the authentic Samsung Desktop charger only activates if fast wireless charging is turned on in the phone.
The fan is to cool the phone.

I use the Samsung desktop stand but usually just normal charge it to which apart from typical heat being discharged I've not experienced any other issue.
I do not use a case.

There is opinion that constantly using Fast Charging can reduce the batteries condition over time. Wether you believe this is personal opinion. I've only Fast charged maybe 2-3 times if I've needed a quick boost of juice.

I noticed this too when I put my new S8+ on the wireless charger built into my truck. This was the first time I tried it so I wasn't sure if the phone getting hot was a normal thing or not

Hi, the phone can handle it if it gets too hot during wireless charging.

Always be assured since that the electric current of wireless charging is 1A, which is lower than the current for wired charging 1.6A. That's to say, it creates less heat while charging. So actually the wireless charging helps prolong the longevity of your lithium-ion battery, except for the longer charging time.

Besides, only semiconductors that flow through current could produce heat (such as your phone's cover), the lithium-ion battery doesn't have current go through, so it's safe from the heat.

I only wireless charge in my car. My dash mount is setup for during the warmer months I will have the the AC it vent blowing cool air directly on the back of the phone. If I don't do this, I get the wireless charging pause error caused by the heat sensors.

Fear not, the phone battery doesn't generate heat itself, the smartphone is actually smart enough to protect itself from the heating generated by the wireless charging unless you put it under the extreme heating weather, so the phone should be safe from the heat.
