Sure thing! Ran a little test this morning:

21C (69F) ambient temperature

- 2019-07-31 7:15:45: WSJT-X, Fan, 4% CPU, 39C
- 2019-07-31 7:16:52: Fan off
- 2019-07-31 7:19:15: 50C
- 2019-07-31 7:35:14: WSJT-X, Fan, 10% CPU, 68C (Likely throttling)
- 2019-07-31 7:35:57: Launched CubicSDR
- 2019-07-31 7:37:56: 56% CPU, 78C
- 2019-07-31 7:38:31: 55% CPU, 80C
- 2019-07-31 7:40:35: 63% CPU, 83C
- 2019-07-31 7:41:06: Fan on
- 2019-07-31 7:41:40: 56% CPU, 72C
- 2019-07-31 7:44:32: 56% CPU, 56C
- 2019-07-31 7:45:42: 40% CPU, 52C

This is running on a stock Raspbian image with apps and config set up via the n7nix scripts. Connecting via VNC.

Thanks,
Chris

Chris,

Could you document what SW you are running and what is your ambient temperature?

Also what does top show for cpu utilization?

And yes fans are under consideration
