There hasn't been any "productive" use of my spare time since I discovered water cooling forums last summer. This would at least give me a reason to learn to use MS Visual C.

What? Deprive you of the pleasure of redoing the TIM joint multiple times? Never.

I did a bit of googling. Johnson Controls has "proportional control" electric ball valves. Didn't find much technical detail though. Hard to say how easy it would be to control such. These valves may not be adequately stable when set between full open and full closed. Also, backlash could make the control system a bit tricky. Possibly worth considering though.
Does the coolant flowrate really need to be set accurately as long as it is known accurately?

Fluke 8840A

Fluke 2190A
- actually only envision using 25 channels or so
(though more would be 'setup' for different testing configurations)
and off a separate GPIB port an HP3456A reading just 4-wire resistance to 6½ digits in 100 reading 'batches' and running a stat analysis on them (but the switching still being done through the 706)
and possibly a Fluke 2180A and 2300A together as well
I don't stand a snowballs chance in hell of writing a GPIB program for these - way too much multiplexing
I do have the manuals for everything, but thats it

It could be difficult to set this up via email. In a sense, you would have to write the program anyway. All I could do is translate your writing into C-language and GPIB commands.
I did look up the test equipment. It appears the 706 has an 8 bit digital I/O port. That port could be used for communicating settings to a fan speed controller and a flow control valve.
If I could do this 'hands on' it would be fun. The multiplexing might make it impractical via email. I'd need a detailed schematic of the setup to have any hope of getting it right. I'd also need photocopies of all the GPIB command stuff in the manuals and maybe the whole manual for the 706.
It's certainly doable, and I'm motivated to do it, if it substantially increases the likelihood that rad data would be available for the simulator. It would be a one tricky pony though, so maybe not of interest?
