Just started testing a 4.1. I've written a very simple program to monitor CPU temp. It reports temp once a sec and blinks the LED for ,5 sec. I've always used the guideline that CPU temp should be around 40C at idle and not to exceed 80C for any period of time. Using the 4.1 and my program I have to throttle the 4.1 down to 150mhz to maintain 41-42C, at the standard 600mhz it's running at 54-55C. Second over clock (816mhz, max without cooling) results in 69-70C. During these tests the Teensy was just hanging in free air on it's usb cable in a room at 72F, restricting air flow (upside down on table) pushed the temp passed 80C.
With the test program I consider the Teensy to be all but idling but the temp has little or no room to support a task.
So
1. What is max temp for the 4.1?
2. Has anyone looked at cooling, and what where the results?
I'm going to put a heat sink on it tonight to see what happens.
