Okay so this is way off topic but I need some help. I tried doing a
Google search but I don't know enough to get my query right.
I have several external components that I would like to come on when my
computer comes on. I would also like them to go off when my computer goes
off. Some sort of electronic switch that I could plug in to one of my
PC's spare 4 pin power plugs work work fine.
To make things a little more complicated (and Linux related) I would also
like this. I have a water cooling system with a variable voltage water
pump. It would be nice if I could simply poll lmsensors and have a
program bump up the voltage until the CPU is below a certain temperature.
Does anyone know where I should start? I don't mind wiring up something
myself as long as I know what components I should be looking at.
Thanks for the help in advance.
For switching AC from your 12VDC output, you may find something like:

For your cooling setup, you may want to look at a D-to-A converter
driving a power transistor. You will have to search for the current
products - it has been a while sense I have looked into them.
