Best way to monitor DE10 temperature

Unread post by luishg »

I'm not sure if the nano FPGA board is equipped with a temperature sensor (like the TMP441AIDCNT, which provides temperature sensing on http://www.terasic.com.tw/wiki/DE10-Adv ... er_Monitor)

If this is the case, is there any easy way to read this sensor?. Through ssh via lm_sensor or similar.

Best,

there is no on-chip temperature sensors.

Hello,
MiSTer project is such a great piece of software and hardware, I'm also worried keeping it as safe as possible.
So there is no on chip sensor.
Is another non-obvious way to detect overheating ? Kind of "throttling messages" in the logs ?
By the way, do you know if the CPU auto-underclock itself when it overheats ?

Thanks

The DE10 is a industrial board and there for very robust. Not even in the official user manual you will find anything about the need of cooling. Just take a look at some of the application Terasic suggests:

Computers
Broadcast
Consumer
Industrial
Medical
Military
Test and measurement
Wireline
Automotive

Passive cooling is good, active is better but not really needed.

I was going to say if you are nervous about the heat, slap a Heatsink on the actual FPGA/CPU Chip.
If you are really concern get a 40mm fan that can operate on 5 volts. Ether Fans made for 5 volts or a 12 volt fan that can run at 5.

Sometimes (depending on who you buy from) the IO shield comes with a Heat Sink and Fan, some people use a generic 40mm 12 volt fan and some use a Noctua fan (NF-A4x10) double check to grab the 5 volt version as the 12 volt version will not run at 5 volts.
It is my great regret that we live in an age that is proud of machines that think and suspicious of people who try to.
