I connected an external cooler to my laptop, which I have to put under it, so that my laptop does not overheat while playing. This is powered by a USB port on the laptop with power. Can this break my USB port for a long time, or does it matter? I think that's a USB 2.0 port.
Depends on the current consumption of the fan…
and whether the fan properly "burns" the voltage generated by the coils of the motor…
but normal are the very neat…
you could test it with a diode meter, if the thing prevents polarity reversal… So if there's a diode from 0V to 5V…
but normally the USB port in the laptop should even be able to burn itself down, which could come as wild… Only from 100V it's probably too wild…
So my fan needs 5 volts in DC, of voltage and so I have no idea.
If it is USB 2, the fan system must not record more than 500mA at 5 volts in high power mode according to the appropriate standards for such PC ports.
So my fan needs 5 volts in DC, from the ampere I have no idea
The possible power consumption of such laptop - cooling systems you should take the technical details of the manufacturer of the external Kühlvorichtung.
At 5.0 volts × 500mA, there may be a total of not more than 2.5 watts power consumption per USB 2.0 USB 2.0 port of your notebook.
Is there a manufacturer on it? Grins
KLIM
Well, after all, he has his name… Grins
normally nothing should happen there…
If you want to be sure, then you can buy something like that: https://www.amazon.de/...ungsmesser
As user says "RIDICC"!
I would advise you personally of it and then feed the USB fan via an extra USB power supply / active USB hub.
This can be very different from notebook to notebook, which the things can handle. In addition, fans can absorb much more power than they actually need when they start up.
