I have a 3570 cpu and using a stock cooler from it. So now, I'm wondering, do I need to change the cooler/heatsink if I'm not overclocking? And do I need to apply thermal paste once in a while? if yes, how often?
Well, I am favorable of after markets coolers. I'd get a Coolermaster 212+ cheap and a reasonable good performance. Well I use Artic MX 4 a tiny pea or a bit of wide line and let it spread evenly by pressure applied,mostly as defined by manufactures manual guide.
PS: I only changed compound when changing coolers.
