Turbo Mode / CPU I've turned off because for me the power of 8 x 3.5 GHz
is perfectly adequate (HD Rendering, Ray Blu -> approx 8GB with HandBrake)
and it takes me a long service life and a low noise level.
The (boiler) processor can be very good undervolt and runs with me at idle,
Vcore at 1,180 volts, instead of the factory 1,425 volts.
The four case fans run at idle at level 1 of max. 10,
CPU fan whisper in Stage 1 about 1000rpm, Temp 26 ° C.
Browsing the Internet, multiple tabs open, word processing about 32 ° C
Under full load (with Prime95) or Handbrake, all the cores to 100%
the Vcore automatically rises to 1.385 volts,
all fans at Max. is the temperature of the CPU to about 60 ° C,
which is too much for me, because that should elapse Max Temp. AMD at 62 ° C.
The CPU fan is moderate volume level with the case fans,
at full load 2700 rpm and is perceived as the mean noise.
Before FX I had the Phenom II X4 955 installed, also undervoltet
at 1.175 Vcore and stable at full load. Idle about 26 ° C,
Full load 46 ° C - the same CPU fan on level 4 !!
For the Phenom II CPU fan is highly recommended.
As I have already emphasized above, it seems to me to longevity
and a low noise level to, so I'm going there now with the
Arctic Freezer Xtreme Rev.2 try.
