To an extent, that is what you will get if you plug it directly into the router's USB socket without an extension lead - the USB socket will be at or near the mobo temperature. If you do use an extension lead, then you could sit the sensing bit on top of the router case above the vents. Or, you could go with a sensor that has a remote probe like: https://thepihut.com/products/temper2-usb-dual-temperature-sensor and place the probe inside the case. For what it is worth, I have used lots of Draytek routers for the last 20 years or so, and overheating has not been an issue generally. I don't even think I have had a router[1] fail - although have had a couple of PSUs die. [1] I have had some of the external ADSL to ethernet modems like the V120 die or at least become unreliable and disconnect at random. -- Cheers, John. /=================================================================\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \=================================================================/
