my proc is too. AMD athlon XP 2500+ is running around 40 C
But im getting a thermaltake smartfan II(or vantec tornado) to put on my heatsink instead of the crappy 60mm 25cfm fan that i have on there. that should lower the temp some. i am wondering, can some1 give me an example of what 55DBA sounds like? a hair blower? A jet engine? An F5 "Finger of God" tornado?
