Do the USB fans shut off automatically when the laptop is closed or shutdown or do you have to unplug the cable every time? Thank you!

USB fans do shut off automatically upon shutdown. If my laptop is merely put to sleep, fans continue to operated even with lid closed.

on my laptops, the fans shut off once power to the usb is cut, so on one, and older 15 inch it shuts off with lid closure, however on my newer 17 inch the fan does not shut off till the laptop goes into sleep/hibernation mode, or i shut it down.

No. It is like your computer, look at the bottom menu at the screen, to "shut down" then unplug the ac adapter.

i can power my fan off a USB port in my laptop. I see the fan as being a nice extra, but is it really needed? How hot does your Mac get without it?

Yes, I have done so on both of mine. Suggest a USB. If you add one internally the BIOS will "yell at you for having opened the chassis". Not a big deal to turn off but.... In any event, I have an internal on one and a USB on the other. Little or no difference in performance.

This unit does not have a switch to turn on or to turn off. You just unplug the USB from your laptop.

I do not, mine is very quiet. Give Vizo a call, they are very helpful. It could be the heat sink on your cpu is not properly seated and not transferring heat correctly. This in turn makes the fan run all the time. You will also notice a distinct hotspot on the laptop if this occurs.

yes, you plug it in and it shuts off when you turn it off. I wondered this too.

no. the plug that powers the fan connects to your USB port on your computer, but the fan itself doesnt have a usb port.

using the wall-to-usb adapter, yes. Plugged into a computer's usb port, not if the computer automounts external drives. And once mounted, it shuts off if you unmount it. It might work if you disable automounting, but I just use the wall adapter so I'm not sure.

there's not a place to plug in a usb cable on the lap desk. there's just a usb cord that's connected to the desk from inside the unit that controls the fan..you can't take it off. the usb cord is strictly for the fan. you plug the cord into your laptop.

I honestly don't know. I can tell you that it seems to be noticeable when the unit becomes hot, which did not happen very much, maybe once or twice. I usually leave it plugged in with my MacBook Pro connected to it. I usually have it on almost 24 hours for weeks at a time (mobile office on wheels). I just keeps doing its job. Unit has never over heated, and I can't remember the last time I even noticed the fan, in fact its real quiet...

I leave mine plugged into power all the time, but I unplug it from my laptop. When I disconnect, it goes to sleep; then it wakes up and mounts when I plug back in. For reference I use a Mac not a PC.

There is a compartment under the mouse pad that you open and in it is a usb cable that plugs into the computer usb terminal and also plugs into the table (IT IS A SMALLER PLUG). The fan comes on automatically. I have never used the fan but once. I use the table about two or two and one half hours at a time.

one usb powers 2 fans, when you plug on both usbs they power all three fans, this is good if you power laptop that produces alot of heat.

Have not had this issue, but would think you maybe right on the money. Your computer may be dropping "vampires" (Items hooked up to your USB that are using power (although very minimal in this case)). As i generally do a daily shut down I have not had this issue.

I does automatically shut off. After owning it a couple of months, I find the "computer disk" noise it makes before shutting off wakes me up. It runs about 6 hours but I find it too noisy when turned on and just before it shuts off.

If you are using the power adapter that is supplied with the USB hub the hub then is independently powered and the external drives are more than likely being "tricked" into thinking that there is still an active connection between the drives and the PC, therefore the drives will not turn off with the PC. If you unplug the adapter the external drives should then shut down also. Will the drives being on damage the drives? Not really, because there is no actual activity (reading/writing) taking place when the PC is turned off. Does it use a little electricity? Yes, but it would be minimal. Bottom line, if you are concerned about the drives being left on, unplug the power to the hub and they should shut down. If it means anything, I have a PC that I built with 5 Western Digital Black Series 4tb hard drives in RAID 0 and a 2tb external WD My Book attached that run 24 hours a day, 7 days a week and they are fine.
