I've had two 3770Ks, the first an average overclocker probably positioned right at the 50th percentile, attempted a delidding myself and cut down into the PCB slicing the dual memory tracers, same day I decided to bend a few pins on the Z77 motherboard just for kicks, most likely a Darwin moment.
Second "replacement" 3770K was an amazing clocker, got lucky in the Amazon lottery, stable at 5.0, bootable to 5.3, still have that awesome CPU mounted on the wall with the ROG Maximus V Extreme mobo.
"How's it hangin' Maximus Five?"
Paid for a 6700K delidding by the Siliconlottery.com guy, he's awesome, the CPU is binned to 4.8 and brilliant thermals using an EK monoblock.
But here we are in 2017, and I would avoid this issue altogether if you are able. Buy Ryzen Performance Series or the Intel X299 HEDT Series in June or Ryzen's upcoming X399 HEDT series using proper solder as your thermal interface.
Nice idea with the cyanoacrylate VSG.
Also, an engineering friend at Harris Corporation sent me this gif with a caption he wrote "How most everyone at OCN.com chooses their new fans"
I would have to agree, and thought VSG being a fan guy and guru, would find this humorous.
