Hello guys
I felt the urge to tell you what has been happening to me lately, I've
got a hp 6720s x3100 C2D T7250 @2,00 Ghz
Yesterday I installed Everest and it showed that on max performance my
cpu temp was about 90°C !!!!
I was astonished (I expected my lappy to be burning at that
temperature).
After searching the net I found that windows 7 has an advanced feature
in the power saving options that allows to keep the cpu at the fastest
speed possible EVERYTIME (thus not scaling speed to meet the actual
needings of power) after disabling it my cpu temp dropped to MAX 75°C.
Please note that "disabling" that option appearently doesn't affect
performance (actually the option itself tells the system to never let
the cpu go under xx% of its speed forcing it to stay at always at top
speed and so causing it to make a lot of heat)
Here's the trick:
Go to control panel>power saving> then choose balanced or high power
energy profile and choose to modify the profile preferences>  then
choose advanced options > scroll down to processor power saving >
you'll see 3 features:
minimum/maximum performance level and system cooling criterials.
If you look carefully you will see that in the minimum performance
level when the pc is not relying on battery is set to 100%. As I said
this forces the cpu to be always at its most power, actually this
dramatically increase heat (wich is a bad thing since our gma is
passively cooled and this add more heat so gpu heat + a lot more cpu
heat than needed = toasted lappy for breakfast). So I set the minimum
performance level at 5% like it is in energy saving mode and my temp
dropped to max 75°C.
I repeat that this doesn't seem to affect performances since the cpu
is still able to be used at its best, but ONLY WHEN THIS IS REALLY
NEEDED, anyways just tell me if I'm wrong.
I wanted to share this with you guys as it really helped me (it is
summer here in Italy so I was really lucky my pc didn't fry)
Needless to say I will go for a "cleaning vents process" too.
I just wanted to give an advice to everybody here, even if you don't
think you risk overheat, spend a couple of minutes in checking your
cpu temps with everest or SpeedFan if you have 7 installed, you'll
avoid bad surprises in the future.
PS Im using an italian wersion of windows so I'm not sure that the
menus and the config voices are translated correctly, I hope you'll
find'em anyway.
PPS the system cooling criterials are "active" or "passive" I think
this has somehing to do with active and passive dissipators but I'm
not sure, help is appreciated.
