TOPIC: Fan Control on SunSDR2 DX

Fan Control on SunSDR2 DX 23 Aug 2022 20:46 #1

This may be in the manual but I was wondering if there is a way to set the temperature that the fan turns on for the DX. I would like to have the fan cut on to keep the temperature below 32 degrees. Any help would really be appreciated.

Thank you but that does not really help. I am looking for a way to keep the radio cooler than 38-39 degrees. I don't my radio to burn out.

I too would like more fan speed control for the MB1. I hope they can add more fan control to ESDRv3 in the future.
I would just connect 12v direct to a fan and just have it run all the time.
Anyway just a thought.

I'm thinking about 100-120 mm water block and an AIO closed loop system
or using a 120 radiator as a block and another larger radiator as heat exchanger with a pump and fan
fill it with distilled water and find a rate of flow that provides optimum reduction in heat

Just a thought

Yes that would be the quietest and most efficient method. But I think using Vodka for the coolant would be appropriate :)

I am saving what I have left of my Russian Standard as I can no longer obtain it, perhaps that is a great thought John, I'll dedicate some of it to this project if i decide to do it.

I like that water block idea. All my home built computers are water cooled. Not only would it be more efficient, but it can allow you to move the fan and radiator away to cut down on fan noise.

:good: Hello everybody,
Fan control, larger fans and more power and probably noisier, water radiator and the devil to four, there is no need for it colleagues ... !!!
Just put a few feet higher, from 10mm to 15mm for the Sun2DX, it is no more than 38ºC - 43ºC.

73´s to all ... !!!
