I must say I never experienced this issue. Not with drivers properly installed at least.

Why do not you care about the W530-540? you think are scarce products?

according to a friend of mine who deals with reballing, the temperature is not the real problem, the real problem is the lack of lead into balls., lead makes the ball more 'elastic welds more' accurate, easy mounting tab without creating tensions within the installation is carried out at temperatures more 'low and do not hassle components etc..

if this were true models before 2005 so they should not suffer from these defects .. in fact my toshiba m30 2004 with NVIDIA GeForce FX GO 5200 has toured for years 24H a day, played with overclocking, the fan makes a noise hell, the keyboard works very badly but still works in the hands of a friend who keeps him always on.

I did a reflow on the t60 , bringing the temperature of the GPU at 260C for 10 seconds, now running again , who knows ' as last' ?

on ubuntu I installed a program that monitors temperature and speed ' fan :

the temperature takes a cycle every 2 minutes going from 40C - 90C- 40C etc. ..
clear that sooner or later, the expansion of the components does break some welding

the system should adapt to the load and stabilize the temperature , do not work this way.

Which cooler is better in your opinion? Bye

I would have to make a direct comparison to say anything about it.

But it seems that the AVC cooler is the one that suffers from poor fit, I don't think your cooler model has that problem.

Adda wrote:I'm not quite sure about the reasoning behind the changes you made, could you try and explain it to me?

It seems you put a thermal pas between the cooler and the plate above it, and put some sort of thin thermal pad on the keyboard.
Similar thinking to the cooler in the T43p.

But what about the foil you taped under the palmrest?

I'm not sure I want to expose the bottom of my keyboard to the scorching heat of the 720QM.

Here is the result of a straight 20 minute 4x max heat Prime95 + furmark extreme burn:

Here is a continuation of the test, but now I have put all the Prime95 threads and furmark on to core 3:

Problem solved.

I have core parking enabled, so the CPU runs as fast as it can.
The GPU runs at 0.85v clocks are shown in the picture.
Fan speed at max (64).

not bad, but i think we can do better

W520 owners should do these mods and post results, right about immediately.

Adda wrote:That will have to be some other time, as I just finished running a half hour test.

Similar result to my last test, so this is really as hot as it gets, no other tests I have run will produce higher temps then this.

Quad core burn:

Adda wrote:Playing Borderlands 2, the GPU in my W510 stays below 60C, and the CPU stays below 70C.

So under normal conditions, the GPU stays between 47 and 60C, quite a narrow temperature range.

Adda wrote:You still have something between the CPU and keyboard right? only difference is you removed a layer?

Adda wrote:To undervolt the GPU first get "PowerMizerManager":
http://nvidia-powermizer-manager.software.informer.com/

Use it to force the GPU to stay at a constant power state, rather then dynamic scaling.

Max perf = 0.93v

Med perf = 0.85v

Min perf = 0.8v

You can set different power states for AC and DC, so why not put the GPU in to it's minimum power state when on battery.

Then get nVidiaInspector:

thank you very much, however I do not want to increase the clock frequency for the time being, I have already 'burnt my T61P so, then for now the power of the GPU enough for me.

if I set the voltage to 0.8 constants, there are problems?

Use it to overclock the GPU, remember to select the correct power state in the overclocking menu (P8 if you run at 0.85v).
Shader clock should be core clock x2.2, I don't recommend overclocking the video memory, just put it at 790MHz.
To apply overclocked settings at startup, right click the "create clocks shortcut" button and select "update startup task".

I think you can safely overclock to 575/790/1265MHz@0.85v (core/mem/shader), beyond that you'll definitely need to test rigorously to be completely free of artifacts or crashes (real world gaming, synthetic tests are better for temperature testing).
