CPU Temperature

Post by w5gw » Wed Oct 31, 2018 3:12 pm

I'm obtaining between 126 to 128 deg F and the color is orange on my DV Mega dual board with RPi. Is this too hot?

I have it in the enclosure sold by gigaParts, not a lot of air circulation.

Many people add a fan or two to cool the unit. I do.
I believe the technical answer is that, at 80 deg. C, the pi issues a warning.
At 85 deg. C, the pi will begin throttling the CPU to prevent damage.

So, temps in the 53 deg. C range aren't a problem.

I think that's the C4Labs case which was lacking air flow. I drilled 9 holes under the CPU location on the bottom piece as I noticed it retained heat there, and it stays in the green and quite a bit cooler with a Pi 3B. I like the look of the C4Labs cases but they could use a bit more design work and quality control. My JumboSpot case was missing a drill hole and included a extra part forcing me to use the Dremel again. Some cut slots on the bottom of the DVMega case would really help it get rid of heat like some of the commercial Pi cases.

Here is the temp key:
< 50°C (122°F) = green
≥ 50° < 69°C (156.2°F) = orange
≥ 69°C = red

I personally wouldn't worry about anything in the low orange range like what you're seeing. I interpret orange to mean "keep an eye on this, especially if it gets in the high end of the orange range" while red means "you need to do something about the temp." I find that the 3B+ and 3A+ tend to run a bit hotter (low orange range), even with heat sinks and ventilation holes in the cases ... but nothing to worry about.
