ml360 subzero, a coolermaster X Intel collaboration , a rare cooler designed for sub zero temps using a thermo electric unit, best cooler for any lga 1200 build.I got this given to me as a customer as partial payment for a pc I built him, it has never been installed just open box from what i can tell (see pic of fresh factory thwrmal paste) and I planned to put it in a build but havent done an LGA 1200 pc to be able to utilize it.
