Hi, ok bit of a noob here, my plan is to overclock a 4670k, not to astronomically high levels but just want to get some increased performance, downside is im on a budget so the cpu cooler is going to have to be quite cheap, ive lined up the Cooler-master hyper 212 evo and im hoping it fit on the g1 sniper z87 that i was persuaded to buy by Mr TTL, as this is a fairly cheap cooler I'm probably going to need to de-lid now here's the thing, unsure how; been suggested that i use a hammer and vice method, and watching a few videos i just want to confirm a few things that seemed a bit risky, the fella i saw do this (Destiny) used his vice a block of wood and a hammer and gripped the cpu via the ihs plate, now logically the only place to put the wood that is left would be the pcb, this is what im unsure about, is it really safe to smack the pcb with wood and hammer?
