Is there any 3 or 5 volt rails on the rbboards to add a small fan
Maybe i can use power from the led light?
To solder in small fan?
No need for it. Eventually take the power from main power input directly which cannot damage anything.
I found jp1 fan terminal on the board
Lucky you.
23 degree cooling
59 degree to 36
And? What benefit you have got from it? Can you overclock it more to get better throughput?
Runs so much better now and nice and cool
