Before stating "it's too hot", has any of you read the Broadcom specs determining how hot is too hot? How do you know that it's TOO hot? Right now, people are basing decisions on mere opinion, with no factual data. When I asked an engineer who actually works with various Broadcom SoC, he told me that some of these chips were rated for as high as 130C.
I used to have an ATI video card that would hit over 100C under load. The card never had any stability issue, the chip was designed to run that hot.
This is why I was hesitating about adding CPU temperature, and I am considering removing it. Brainslayer had the exact same train of thought with DD-WRT after he added the CPU temperature.
If people are going to get paranoid about temperatures, then I will simply remove them from the webui.

I work with a company that uses Broadcom parts (mostly 10G switches). We are evaluating a potential design that would use this part. From what a HW engineer told me, the 4708 has a Tj max (Thermal Junction) of 125C.
