I installed the latest SpeedFan for my Dell Studio 15 Notebook, which after installing Windows 7 on it, may turn off by itself after some use.
SpeedFan used to not tell the speed of fan, until yesterday I checked the box in the Options that says: "check this box for Dell notebooks", and the fan's RPM is shown.
The temperature of the GPU, as well as one core was as high as 85, and sometimes drop to 80, but I am suspecting this may be the problem of the computer turning itself off. I check the box "Automatically adjust fan speed" or uncheck it, and change the fan speed % to 100%, but the strange thing is, the fan may slow down after a bit, and when I change the 100% to 95%, I can hear the fan revving up -- to a higher RPM -- being more noisy as well (RPM now showing 5300 instead of 4200), but after some 30 seconds or a minute, it will slow down again, to being more quiet. And after unknown time, the computer will turn off by itself. I tried again using "Automatically adjust fan speed", but also after some unknown time, I come back to the computer and it is automatically turned off again (it is by powering off itself within a split second, instead of doing the proper shut up which can last 20 to 30 seconds).
Is 85 too hot for the GPU and the CPU? Can't SpeedFan be adjusted so that it just make the fan go 100% all the time -- at least during this experiment -- so that the computer won't turn off by itself?
