    as i said.. try using a big heatsink...

    for temp testing use cpu float app. I stressed the cpu and got 65 max...
    Thanks for the app - works great!

    In Antutu i noticed max 46 once...
    In games it stays around 40 and in youtube below 40.
    In LibreELEC while playing a 1080p h264 movie, the temp stays below 35...
    Active cooling should be better anyway...

    yes it is higher than you can put. and wider... 33mm wide and 9mm high.

    this is why i mounted a mass square on the cpu with a huge but thin plate

    My little mod includes active cooling.
    The reason for this is simple - my box needs to be in a cabinet together with all my other devices - receiver (hot), my TV provider box (hot), PS3 (hot).
    And my setup means, that the H96Pro+ would be "on" all the time - LibreELEC has been denied the use of power button (box won't power up after shutting down from LE) and Android puts it to "hot sleep" - box remains semi-sleep (meaning - hot all the time).

    So, I got a small fan (35x35x6mm), 5V. Unfortunately the box cannot power this fan - it won't even boot fan attached and when plugging it in when box is running, the box will crash... And the 3-pin socket will output only less than 3V (fan will not turn on). So, I plugged it into external USB adapter - fan is running 24/7 and it is making a little noise all the time... At some point I might try with more powerful adapter on box to see if it will power the fan or not...

    The fan is blowing air from outside to the inside of the box.
    • I removed the plastic diagonal "sticker" and cut a hole in it (plus I had to remove some of the "sticking plate" from top cover of the box under the sticker) for the fan and attached the fan to it. Then the sticker was put back...
    • Since I already had an opening for hidden USB ports, I could take the wires out from there...
    • My box needs to be on the wall, so I added some "tape" to attach it to the wall with 50mm opening on it.
    • The fan is drawing cool air from outside the cabinet to cool down the box.
    • And since the cabinet is located on the floor, I needed additional dust protection for the hole in the wall...
    See attached pictures...

    Results.
    Before the mod my box was idling at temperatures 55-60 Celsius. And the peaks I saw were at 75-90 Celsius.
    After the mod the box is idling at 31-36 Celsius (depends on whether the receiver is hot or not) and I have seen only some peaks over 40 degrees Celsius - the fan cools down the box so fast, that after playing Clash of Clans I need to be superfast to open the temp app to see the temperature drop pretty fast I have not tried stress-testing the box...

    I tried the other way also - suck the hot air from inside the box. This resulted in ~5-10 degrees higher temps...

    PS. Obviously I do not use the original remote for the box, I use Logitech Harmony hub+remote.

    All I did was remove heat sink. Installed with thermal paste that Trebor posted. Cut bented hole in top cover no heat issues now runs fine on any software. Click image for larger version  Name:	20170819_155746-747x1328.jpg Views:	1 Size:	147.8 KB ID:	676803

    i can't see your temp but i used the original box... small and very compact

    adding picture of the huge heatsink i added. it has a big mass popping out and touching the cpu and a huge plate to absorb the heat. max temp 65deg

    The intel atom fit exactly in the box. I removed the 4 standoffs and used adhesive 3m to glue the heatsink to the two usb ports so it won't move.
    And of curse, i use the built in intel heatsink thermal pad...

    Results before the mod was 79 deg in stress test...but not using cpu floating app it surely was higher.

    Results after: i will update soon with pics...

    Still no pics but same test with new heatsink and temp are 59max.

    Now using cpu throttling app i got the cpu temp running max 64 deg...
    Updating:
    everything is working good. Stable and the box is on my cable box so it is idle at 55 deg. But max 64. So it is stable.

    I will replace the thermal pad with thermal paste soon and see changes...

    I highly recommend putting any aluminium metal that can fit the box as a heatsink...the more metal,the lower the temps.

    No need for fan if the heatsink is big

    Where you weld the wire of the fan, someone have a picture of that?

    I think that if it 40mm it will touch more components than needed...not cpu only.


    Anyways, what is the temperature?

    im not sure of its dimensions and its sealed back up now but around 40x40x12 maybe or 40x40x10 not sure

    temp its far better but hard to say for sure as i didnt do any directly comparable tests
    it certainly doesnt ramp up in temp in an instant now as it can absorb far more heat than the stock sink

    before with the default silver heatsink doing a full fresh smb kodi media scan on 70 TB of tv shows
    it would go pretty much straight to 80 after maybe 30 seconds of scanning it stays under 65 doing that now
    its around 49-50 playing a 1080p web-dl

    with regards to touching other components its a case of checking before fitting it what not to touch e.g. whats higher than the soc
    it wasnt hard and if you want stealth its just about the largest practical heatsink you can fit inside

    so on the face of it 15 degrees cooler under load but its actually more than that if you think about it
    doing an smb media scan it would hit 80 very fast (80 is when it gets thermal throttled hard )
    so its staying at 80 whilst being throttled but now its under 65 not being throttled

    setcpu stress test only loads 4 cores but that would take it to 80 promptly
    setcpu stress test on 4 cores its in the 60's now
    pressing home then loading another instant of stress test (bug on setcpu you can use on it to load all 8 cores)
    its around 75
    then firing up a kodi video so the gpu is used takes it to 80
    but we are talking 100% cpu load here and gpu load

    i have just ssh'd into it
    its been sitting idle in libreelec all night and its temp is 46 thats idleing at min 1000

    LibreELEC (community): 8.1.9 (S912.arm)
    h96pro:~ # cat /sys/class/thermal/thermal_zone0/temp

    Its the new type H96 Pro+ top cover so it had a lip inside around 4mm that i had to shave off with a blade
    Its actually touching the top of the case when closed up so its as tall as you could go for stealth

    Its around 4 times the mass of the default silver heatsink that it came with
