What coolant to use??

Hi all

Many thanks, as I will stick with my rad and fans and just add a slightly bigger tank to allow for expansion.

Hi All
I was just wondering where it is best to put the rad. Between the pump in the reservoir, so it pumps the water through the rad before reaching the spindle, or between the spindle and reservoir so it cools it coming out the spindle before it goes back into the reservoir??

It does not make a difference. Since the flow rate is reasonably high, once the system has reached equilibrium the temperature of the water at any point in the system will be virtually the same...only a couple of degrees difference, if that.
What does make a significant difference is the length of the pipes (flow resistance), so if either system uses shorter pipes overall that's the one to go for.

Liquid Paraffin Oral Emulsion BP or baby oil? The advantage, if there is a leak, this won't short any of the electronics, in fact, they can be completely submerged in it! I know a guy who has an Xbox currently running, sitting in a fish tank full of baby oil to cool it! (he is a liitle ecentric though).
