CPU running hotter than usual

Hi everyone,

I have a Sony Vaio cw1s1e that runs a core 2 duo p7450, and after a year now the idle tempeture of the cpu is 57-60.

now under load, from streaming on the web or gaming on facebook

the temperature is at 82-83 C!

what is wrong? im thinking of dissassemble the laptop to put new thermal compound on.

its not a dust problem so what can it be?

any help would be appreciated

 

Have you ever dissembled the laptop to clean out the dust? If your just blowing air through the vent, thats not helping much. When I repasted(I used Antec Formula 5) my CPU temp dropped like 8C.

 

yes i dissassemble and looked at the fan. nothing there and.. but i could't dissassmble it completely.. a flat cable was still on th backcover, cant explain.. but i was afraid to break anything, and couldnt see where the cable was connected..

might try it someday, when the waranty is out.. will use throttle stop for now

 

Using ThrottleStop will not remedy a dust bunny in your fan. Unfortunately many Sony laptops don't have easy access to anything, not to mention the fan.

 

using it to undervolt, and set the multiplier down a bit, dont need all that cpu power anyways, now under load it hits 72-74c.

yeah thats the biggest downside of sony's laptop.. im used to just being able to check the fan easily on my old Asus.. wish someone could make a guide.

 

use a small fan on high power, till you find out whats going on,,,maybe the cpu fan needs to be replaced,,I use AS Arctic Silver 5,,polysynthetic silver thermal compound.

Not all Sony's run hot, here are my temps after 30 minutes in Far Cry 2(set on 720P, DX10, medium)

 

no not all sony is runnning hot.. mine didn't when i first bought it.. but after a year and 3 month it is.. compared to ur laptop mine is a core 2 duo 45 nm chip urs is 32 nm if i remember correctly.. normally when i play games it only hits 65-70 max. but its way over now... gonna do a check later tonight luv the laptop otherwise

 

Even though yours is 45 nm, Arrandale chips have the IGP on the chip so it really evens out. P series Penryn chips can run very cool, as they are 25 watt. Arrandale Core i3/i5/i7 are 35 watt dual cores.

 

Can you post the voltage for each multiplier when you undervolt? Are video core, memory, shaders clocks set to factory default? ... and do you think there's any intensive process running that'd explain the extra heat?

 

didnt know arrandale had IGP, gonna read about it later thanks for pointing out

finished dissassemble it and cleaned, everything and with new thermal paste. idle at 44-47C now and on load 59-63C

amazing how much that helped.. Sony put too much thermal paste.. is that normal for laptop? i've been told that u dont need to put much on.. only a very thin layer... but when i but new thermal on Xbox360, ps3, or companies computer they use soo much..

at max multiplier 8x i have 0.9250 normal its at 1.150

GPU is all sony's default, which is underclocked from what the, core, shaders and memory is normal on a 230m.

My laptops speed GPU(default)
Core: 450 MHz
Shaders: 990 MHz
Memory: 680MHz

Everything is great now, thanks for all the input!

Default setting by nvidia:
Core: 500 MHz
Shader: 1100 MHz
Memory: 800 MHz
