Sorry if I say something wrong.... but look at the CoreTemp pix, I cannot tell if that temp was at loaded or idle stage..... Top one can be @ loaded, bottom can be @idle ..... Need additional screenshots for clarification.

I saw your 1st pix in Liquid Cooling sub-forum .. Must admit that WaterKeg look awesome ... Nice design .... a little big though .. but that's good for cooling big rad.

Wow .. with that big WaterKegIII, who need Full Tower case
