Okay I use istat menus 3 I got a new macbook pro today 2011 15 inch quad core the base 1799 dollar model>i don't use this type of gear much. I am a desktop guy. mac minis and mac pros. my istat menus reads one fan at 0 rpm and the other at 1999 rpm yet both fans seem and sound like full speed. I ran a smc reset and it still sounds like both fans are at 5500 rpm. the istat reads 0 rpm and 2000 rpm and even if i run programs like cpu test the fans sound super loud . I did two mods 8gb ram and i put in a 7200 rpm hdd. can bad ram do this? or do I have a bad logic board?
