Well it's tax return time which means upgrade time. New CPU air cooling... What do some here suggest? I'm currently using a Cooler Master 212 on my current and outdated i5 3570K @4.4Ghz. This unit has been a value considering it allowed me a stable cool OC of 4.4Ghz on my old 4 core intel, but I'm upgrading to a K series i9 and not sure if the 212 cooler will do the job effectively for me with the new i9 when overclocked. Can I get some suggestions for a good air cooler priced under $100 bucks? Thanks. (As for the size of the new unit, I don't think that will be a problem with space because i'm still using my rather large Cooler Master full tower.) Regards.
