Max: WIth just one rad one block and little tubbing we dont need much coolant. So fluorinert can be done cheaply. Also can be done with alcohol as well.
LHG: I can pump up to 180w of heat with this TEC at 5v. That is the advantage of running a big TEC at low voltage. 150w was a bit high to be on the safe side. Coolant temps just isnt gonna happen, not with this setup, All I have is a coolermaster bay temp reader and I have taken enough critcism, hehe.
