Yup, the answer was pretty much as simple as using DICE or LN2. But an undervolted chip cooled by a high end WC loop can hover right around the ambient room temperature.
What you state has nothing to do with your snapshot. I have no idea if you're using a high quality WC, but you're definitely not undervolting to get your OC clock. Even a high quality WC will not give your core temps below ambient. This is not an opinion but a fact.
