System temperature really hot

[plumcraft]

Hello,

I’ve tried the module mm-system-temperature to display the raspberry temperature , it works fine except the temperature is around 73-80 degrees celcius (163-176 fahrenheit) , my living room is around 25 degrees.

Does anyone experiencing the same issue ?

Thanks

My mirror is around 65°, but I’m using cpu intensive voice recognition

My system runs 144F when in a case and about 130F out of the case (well, with the top removed). It a Vilros case for the PI3.

Is your Pi in a case or somewhere where there is no good air flow? Do you have a heat sink on the CPU?

That sounds about what my rpi was doing. Mine was closer to 65-70 °C. Then I bought this case and now it’s consistently sitting around 45-50 °C. Even with processor intensive tasks, it rarely hits 60°C.

@KirAsh4 How quiet is that fan?

I’m also having heat problems with a Raspberry Pi 3, gets up to 80C then starts to give the rainbow square in the corner.
I’ve just tried underclocking and it’s not making any difference:

arm_freq=900
arm_freq_min=60

My load average is hovering at 0.8 with four cores!
I think I need some more ventilation. When I remove the mirror from the wall it cools down considerably.

My fan is quiet, but remember that these are cheap fans. You may get a very noisy one. Fans are cheap, you can buy a bunch of them and figure out which is the quietest. Or you can find some really quiet ones through an electronics vendor such as DigiKey or Mouser, and pay a higher price for them. I replaced two 30mm square, very noisy fans on my 3D printer, $7 each at the time. Now they’re a little over $9. Good fans are expensive.

FYI, both my rpis are running at 1GHz.

Thanks for your replies, i’m going to buy a new box for my Pi 3 with a quality fan

Thanks @KirAsh4 ! I bought a case to try out as well.

Mine is around 65C as well. Stable, for the past few months.

Good to know: mine isn’t actively cooled. It’s not inside a box, but it is inside the Mirror’s casing.
