I have a new PC and I have found out that my motherboard was a dud right out of the box. I need to send it back to ASUS to get a new one and I need to remove my corsair 100i v2 AIO watercooling unit from my CPU. I am new at this building process and I don't know if the thermal paste hardens onto it or not. I am worried about damaging my brand new core i7 6700k CPU in the process of removing the water cooler. Please help with descrIcing how to properly remove the cooling unit
