If it was just sitting there on, but not doing much, then that is not much of a test. You measured the temp with it indoors and sitting there. What will happen if you use it portable on a hot day? And the software for all the applications and modes is not finished yet so you really don't know. They WILL get hot during high CPU usage and throttle back(slow down). Lots of Pi users (including myself) have had to add a fan to keep them cool if the application is CPU intensive. Max

I am convinced by now that heatsinks are unnecessary - vcgencmd measure_temp tells me the RPI measures 56.4c after 5 hours being switched on, surrouding is about 26c.

The processor gets warm but is well within specs. Mine has small paste-on heat sinks, but that's because I had already installed them when I was using that Pi for other purposes; I bought the basic kit. (I have switched to an RPi Model 400 for what the one in my sBitx used to do.) If you want to install heat sinks similar to mine they won't do any harm, and might help if you operate your sBitx in very hot conditions (say, on a picnic table in the sun); they are readily available for a couple of dollars. A more substantial heat sink like one of the tall tower ones (with or without fan) should never be necessary, and might cause a problem fitting the Pi into the sBitx case. > > > > |
