VK-T40E - Safe operating temperatures?



  • Hello all,

    I've recently purchased a VK-T40E and enjoyed setting it up on my home network.

    Due to a switch of locations within the house for my computer setup, the cable modem, VK-T40E, a NAS and a small gigabit switch (Netgear) are running on the shelf in the wardrobe of a spare room.  In one aspect its good, as everything is out of sight and the computer desk and surrounds are clean and uncluttered.

    I monitored the temp via the dashboard on the web interface of the VK-T40E, and noted it was just sitting over 60 deg.  I felt this was a little high, so I purchased one of those laptop coolers and the VK-T40E is now sitting on a couple of spacers on top of the fanned cooler.

    The temp is now sitting around the 57 to 58 deg mark.

    I was just wondering what temps other users of the VK-T40E sit at and whether I need to invest in something more solid for cooling.

    Any ideas / assistance would be appreciated.

    Marty.



  • You could drill a hole in your refrigerator door big enough for a small bundle of cat5 cable and a power cable.  Run the the cables inside the refrigerator (or freezer) and attach those to the pfsense and set the pfsense down on the shelf inside.  Then seal the hole in the door with calk.  Mount a managed switch to the outside of the door over the hole you made.  For cosmetic reasons, this is best placement.  The switch will be fine without refrigeration.  Attach the switch, modem and other devices to the cat5 cables outside the fridge.  Done.

    Kidding - Passively cooled things tend to run a little hotter than fan cooled things.  I think you are fine.



  • For the record, a test APU system sitting on my desk in about 20C ambient temp, running latest 2.2-BETA is showing CPU0 and CPU1 both on 59.5 degrees C.

    Thank you for checking that.

    Its around 22.5 ambient here, so that is a good comparison.



  • The G series processors (I think thats what is used) is rated up to 90C Tdie.   
    So it can get alot hotter before you have worries.

    There was significant concern amongst APU early adopters about the temperature as I recall. I have yet to see any actual reports of failure though. It just runs hot, which is not unusual for a passively cooled device.

  • Thank you for the replies.

    I'll keep an eye on it over summer.  I think on the 40deg+ days the laptop fans its sitting on will help!
