That looks nice and i hope you will solve it out.But do NOT touch the CPU head with your fingers.Place a smal dot with thermal paste on the CPU and back with the Cooler who will sort the rest out.Again, DONT touch or thermal paste the CPU with your fingers.The built in cooler in your G20AJ is probably the same as in my G20CB and that manage the heat from a i7-6700K really good.Have a nice day and Fonzie Bulldog says hello to the cat. 🙂
