Nice, what will be the immersion fluid? Be sure to put something like copper sulfate in the glycol loops to prevent inferior organisms taking over.
Novec 7100. I have some test fluid on the way and hopefully I can get a test Neptune in the fluid on Monday or Tuesday and see how it does.
Looks like a nice setup.
Are you using free air cooling or is it ACd?
With immersion you should get a better PUE, N7100 is single phase, right?
Is the stuff expensive?
How high is your power cost? Are you doing immersion because of high power cost or for fun?
