Laptop fan ALWAYS on - advice?
Discussion
Folks,
I have a Toshiba laptop that was perfect for approx. 15 months until last week - it kept freezing at different stages in the boot sequence.
Anyway - I took it to a local PC repair place and they diagnosed a hard drive fault, so they replaced the HD and loaded W7 onto it at the same time. It had vista before. They also gave me the old HD away with me and I was able to recover most of the data on it, although some files must have been on the section of the HD that was damaged.
The above isn't hugely important apart from context. Before the HD failed the fan would come on when the bottom of the laptop was very hot and would stay on for a minute or two then go off again.
Now, when the fan comes on it stays on constantly until I close the lid. The bottom of the laptop is hot when the fan comes on but then it cools, and it's cold air thats coming out of the vents eventually.
I am never doing anything intensive when this happens - just surfing the web.
Is this anything to worry about? I am slightly concerned that the fan might burn itself out - is this likely?
I am no computer expert but I had a quick look in the BIOS at startup and I couldn't see any fan options. Is there a problem with whatever sensor picks up that the temperature has returned back to 'normal'?

I had this problem with my old laptop; took a hoover to the fan and heatsink outlets and all manner of s
te came out. Next time I turned the laptop on, it was lovely and quiet! Fan problem solved!
Worth a try?
This. The insides get that full of crap, especially if you put the laptop on your knee, over a table.te came out. Next time I turned the laptop on, it was lovely and quiet! Fan problem solved!Worth a try?

Sometimes, fans are controlled by software loaded on the pc. It may be possible, that the controller software was deleted from the vista os, and not replaced on the windows 7 install?
Might be worth checking for updates.
You could also try a program like "speedfan" to control the fanspeed if windows7 isnt doing it properly.Might be worth checking for updates.
My laptop fan got filled up with dust and I had the same problem.
I took the bottom off the laptop and cleaned out all the crap and its been fine ever since.
When I took it into the wee PC place the guy had a wee compressor that he fired up and used a nozzle thing attached to it and blew a whole load of junk out the back of the thing. So the fan & heatsink should be clean!
It's obviously working as it should, right up until the point where the CPU cools down.

Pre-built computers almost always come with a load of extra stuff, especially laptops.
Have you tried looking on the website of the laptop manufacturer to see if there's any drivers/software for fan control for Win7? Might be worth a try. The vista ones may even work.

t out of the inlet. You could hear the fan whizzing round backwards, which was a bit worrying, but nothing broke. Just about twelfty million bellybuttons of fluff came out I reckon.Instantly knocked 30degC off the CPU temp. Playing something on YouTube no longer results in the laptop sounding like it is about to take off.
Just like new.
