My CPU runs at a max temp of 72c under full load after running 8 instances of Prime95 for 12 hours and typically runs in the mid 60's after a long gaming session and idles at 42c. Another couple hours of lapping for 2 degrees of improvement wasn't worth it to me.
But those surfaces you polished look nice.
I just need to be flat - the thermal paste takes care of all the little dentures and whatnot.
Finding it hard to lap my i7 as it seriously hurts the resale value.
