[Martinsliquidlab.org] Sunbeam Rheosmart 3 Review

[mm67]

I'll add in a wiring schematic later this evening, but it does have two input ports and three out.

4 pin molex = power source input
4 pin fan connector = PWM signal input from motherboard CPU fan header
3 pin fan connector = Analog voltage control fan out

It comes with several cables that connect it all up. The PWM cable has a splitter male end which I have been using to connect the mcp35x and a long female end that runs to the controller feeding two devices PWM signal.

It works as good as you PWM software, but I do wish I bought a gigabyte MB now because easytune is a lot more advance that speedfan.

This won't do as much as some of the better controllers out there, but it can at least give you basic on/off temp dependant auto speed control.

I'll spend some time learning more about speedfan and write something on that later too.

Asus FanExpert is a bit more advanced than Gigabyte's ET6, it has three setpoints for temperatures, I for example let MCP35X ramp up slowly until temp reaches 55 C, after that it starts to ramp up quicker. This way pump stays quiet until maximum flow is really needed.
