Overclocker99

hello everyone! this is my first post on this site, i want to buy the ASRock B150M PRO4/Hyper motherboard to overclock an i5 6500. now the specs on the motherboard's page says that the motherboard has an external BCLK generator which should let me OC without being restricted by the BIOS updates. if i succeed in OCing the CPU, will i be able to read any of the CPU's temperature's? and is the AVX instruction set very important?
