PTS Flowbench Forum

I am almost done with my bench and I am wondering...should I install a cooling fan, similar to a computer fan, in the enclosed area of the bench where the manometer, motor controller and ssr are located to cool them?

Thanks,

Larry

I am going to. Electronics like cool.

You won't need a lot of airflow, but a small computer fan would be ideal.

The rule of thumb with the SSR heatsink is that if you can hold your thumb continuously on the heatsink without screaming, it will be fine.
The pain starts getting serious around 60 Celsius.
