Do these things have a FAN or not? And if so, how HOT do they have to get for the fan to "kick-on"? I bought one and returned it for "fan not turning"

These do not have a fan. The vented body is a heat sink to dissipate the heat of the transformer to turn the voltage from 120 volts AC into low voltage DC current. (they will be warm to touch).

Yes, they do have an internal fan. From my experience, it's supposed to be on at all times to keep the whole thing from overheating.

Can't really say what the cooling mechanism is ... but mine has no fan. I have two of these and have been quite happy with them.

Fan does run at all times, however it appears to be thermostat controlled and will only really spin up when under load. Even then though when I am using this unit its pretty quiet and never really gets hot.

No, it doesn't have a fan. It works like the rods but seems to put out more heat.

Yes it has a fan. I used this live quite a few times and even a few house parties where it ran all night. I have never had a problem with it

They're always on, i think the thermostatic control regulates the speed of the fans but I am not 100% on that as I never an issue with heat. They are very quiet though, a light hum is all i get.

It's probably the fan because it's pretty loud when it's trying to cool down. I suggest you mount it on a flat un carpeted surface to let air circulate better. Mine always ran hot so I had to build a amp rack for it with 2 fans on the bottom. If it starts overheating like mine kept doing, you might need a bigger, better amp.

Is there any confirmation from the manufacturer that the fan should be always on or not?My fan does not running at all when I charge my battery. Really afraid that the charger could be getting to hot or burnt out...

Nancy, after inserting into computer, make sure both the buttons next to the plug on the back are pushed in. This turns on all the fans. Let me know. Mine works great.

I asked the same question to manufacturer; they said yes it was normal. Sometimes my fan would not even start until there was enough heat generated for it kick in. I can only surmise that the machine is smarter than me!

Sorry. I got a defective fan and so returned it. Didn't run it for anywhere near that length of time.

The fan runs (if it works) when the heat is on. it has different settings (hi,low,economy and temp setting.) i don't remember if it had fan only but most usually do just check the box before you buy. however i do not recommend buying it as mine wouldn't turn on other than the power light and the word hi on the read out. please read my review as i have had nothing but problems with Holmes products.

It does not have a fan, when plugging in the hard drive the same is exposed and has no need for a fan. I have a hard drive plugged in that's similar to the one in my desktop and use it to update on a weekly basis a clone copy (mirror Image) of my hard drive. This is done in conjunction Carbonite Back ups.

Sorry I cannot help you there. When I bought mine I am not sure if the fan was defective but when I turned it on it bearly, I mean bearly blew any heat, so I sent it back to Amazon and did not get a new one.

The base of the fan needs to come in contact with the hot surface of the stove. The heat from the stove transfers up the base and heats up a thermoelectric device that powers the fan motor. The hotter it gets the faster the fan turns. So you need a hot surface to set the fan on or it won't spin. And if it's not hot enough, it won't spin fast enough to move the air.

They do work fine without a fan, but the metal plate on the back gets so hot to be untouchable. It's enough to have a small usb fan to cool lot of them.

It does no come with an off/on switch, but you could have one wired in if wanted. they are designed to run continuously. the fan runs quietly, but you can hear it if stand close. Try unplugging and plugging it back in to hear the difference. If you can't hear it, it's not running. You can also feel some slight vibration if you put your hand on the outside of the fan.
