G1S vulnerability to temperature changes

Well...
I heard so many times already about G1S's high temperature and the stuttering side effect once the temp goes beyond 95C. Personally I dislike the idea of removing the tape at the GPU ventilation area and putting the laptop into sleep mode because it will just raise the temp even higher in the long run.

So... I found some interesting things...
I was using 175.16, once the temp reached 95C it didn't stutter immediately (took about 15-20 min to happen). If I turn the air con in my room and set my laptop cooler (Notepal Infinite) to at least med setting, the stutter immediately disappeared. I tried running the laptop for 2-3 hours under this condition and the stutter did not happen at all.

Now with 175.19.... the shader optimization worked pretty well when I tried the driver. It didn't increase the frame rate in my case but it stabilized the frame rate. I tried Crysis and Bioshock demo and the frame rate never drop below 15 for med-high setting. With no air con, the stutter took place immediately once the temp hit 95C, but it can be remedied easily using air con and notepal infinite.

So... I am wondering is G1s really vulnerable to temp changes (especially high temp and room with no air-cond)? Is there a driver that can fix this? Thanks

 

one can speculate that drivers can change the efficiency thus generating heat at different rate hence affecting the stutter encountered..

 

Drivers can change the temperature of the GPU. Unfortunately for us this seems to be when the drivers are not to well optimized, so we do not benefit from the optimizations. Using better, more optimized drivers we may get good perfromance, but at a cost of higher temperatures.

 

You can avoid the stuttering problem , by turning closing your screen , wait until low consumption mode, then turn it On again , and it'll works without temp regulation.

 

He already mentioned that he's not happy putting it into sleep mode to increase the throttling threshold temp.

 

Exactly... that is why I am looking for a "miracle" driver or bios ...whatever can remedy this problem. If I am not mistaken a few weeks ago somebody from this forum made a review about a mini laptop cooler that can be attached to the exhaust fan, somehow making the exhaust more efficient because it draws the hot air faster... I might be interested on that product but somehow I can't find the link of his article. Can somebody help me find the link? Thanks

 

This appears to be the thread you are referring to.

Another review of the "Magic Laptop Cooler" can be found here.

 

Thanks for the link, man. Btw you're a G1-S owner too aren't you? How's your temperature? any probs so far?

 

I realized the higher temperatures too. Thats why i cleaned my fan and put the back of my g1s a bit higher.. that helped for a few degree.

 

Before I applied Arctic Silver 5 compound to the heatsinking I routinely reached 110°C and would experience downclocking. Idle was around 77°C and a load raised temps to ~97°C and often continued to rise to 110°C. The higher temps were experienced more often when the room temperature was 35°C and above. Because of this I applied the Arctic Silver 5 and the idle temp is now around 67°C while the temperature under a load is around 85°C.

Although performance was worse with higher temperatures, I don't believe I experienced stuttering.

Maybe this is why?
