I about to start a new build, with the 555 dual core processor.
I wanted to try unlocking it to a quad core, but will not be doing any actual overclocking. Does anyone know if it will run at stable temps with just the stock cooler?
I unlocked my 555 to a quad but it needed +0.025v to boot.
From there it went up to 3.6v stable before any more voltage was needed so its worth considering an overclock that doesn't increase the voltage for the obvious benifits.
Generally the stock coolers aren't too good, they will keep it cool at low voltage but most even cheap aftermarket coolers with 120mm fans will drop the temps and the noise in your case, highly recommended upgrade.
Luckily the 555 seems to run pretty cool, good luck with the unlock.
