I've had heat problems from day one and I've known the reason for this
since day one, but now it's getting out of hand.

The problem is toshibas software which controls the fan, at least i
think so. The thing is that the fan RPM is too low and only when the
computer gets to the point of no return, that is a shutdown due to
heat is waiting just round the corner, the RPM goes up, but of couse
at that time it's too late and the computer shut down.
So, what im saying is that the fan only really does anything to cool
the computer when the cpu gets close too or above a 100 centrigrade.

I have tried just about anything short of taking the laptop appart and
hardwire the fan in such a way that is working at high RPM's all the
time. Speed fan doesn't work, I haven't been able to find any
information that might enable me to write the software my self and as
more and more dust is collected of course the problem gets worse. Of
course I intent to clean out the dust, but i allready know that it
won't solve the problem.

I have allso tried to downclock the cpu and gpu, but oddly enough it
only makes the problem worse.

Anyway, I hope someone is able to help me.

I don't think I would blame the software for the overheating problem. As
it sounds like to me the heat pipe is either filled with dust, or the
thermal grease has dried out.

There is a Toshiba fan utility to manually force the fan off or on (full
speed). It can be put into an autoexec.bat file and the fan will run
all the time, I've done this on occasion. One thing is that I'm not
sure that the version I have works with current generation Toshiba
laptops, there may be a newer one. There is also a fan power save mode
in the bios which has "maximum cooling" and "maximum quiet" modes (the
names may be different).

Also, your fan and heatsink may be clogged with dirt / dust / hair. It
is not uncommon to have to clean laptop cooling systems about every 6
months or so.

I've heard of this. Actually i have heard about two versions, one for
older and one for newer laptops, however i haven't been able to find
any of them.


I am perfectly aware of that problem, however if the fan only turn on
when it's allready too late, it won't solve anything, only postpone an
eventual shutdown.

On another note, every time i try to get help from people on this i
allways get the: "your should clean out the dust" and so on, so to
other people, please be aware that this is not the problem that i'm
trying to solve.

I have an old version of fan.exe

You are incorrect when you say that "if the fan only turn on when it's
allready too late", at least to the point that if the machine hasn't yet
shut down, it's not too late. When it turns on, the CPU temp will begin
dropping IMMEDIATELY. If the machine hasn't shut down .... it won't.

But often cleaning out the dust IS the fix for the problem.

That is a mater of discussion, but if you would send the version of
"fan.exe" that you have to zacariaz (at) gmail com, i would be very
gratefull.
