I forgot to mention that I'm not going to overclock at this moment. So the question is: Will the TX3 EVO keep non-clocked 4670K cold?
Yes, but if you intend on upgrading, cut the TX3 out of the loop (unless you have it already or can obtain it for free) and save yourself some money. Get the 212 EVO later on. The stock cooler can handle a stock CPU.
