Read the statement by Michael Teeuw here.
System temperature really hot
-
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.

With mine, as the temperature started to get higher and higher, the HDMI started dropping out. It would cause the monitor to blank out momentarily. It would stop late in the evening and be fine, but then during the day I would start seeing it again. Boosting the HDMI signal on the rpi didn’t help (in fact it made the temperature go up a bit higher even), but whenever I just blew across the rpi’s CPU, it would stop. That’s how I realized it was just getting too hot, even at the default speed. Now that I put it in a case with a fan, I haven’t had any issues.
