Hey Guys. Im sure this is one that comes up a lot, yet nothing has settled my mind yet. I own a aluminum, '09 13" Macbook with the standard memory ect, Yet whilst running only Safari and iAntiVirus in the background I have just hit 175 Degrees Farenheit with a minimum fan speed of 3500 RPM? I do use my Macbook as a "Lap top" as i own a 24" iMac, Yet i still never expected this level of heat? Should i be concerned or take steps to dissipate the heat? Thank you for your time, Much appreciated. ~Rob.
