i have a toshiba tecra S1 laptop and the fan is very noisy, its got worse this past month, and i dont know what to do about it.

my warrenty ran out last year, and it's prob gonna be pricey to send it back to toshiba...

any suggestions?

how do you use it when it is on?

just normal usage, really... ive unplugged it and its running off the battery and its still noisy.

i do use it alot and leave it switched on almost all the time, when it started being really noisy last night, i switched if off and left it off for about 12 hours

noise from the fan is usually overheating in my experience...i mean i don't know much about these things, but when my laptop's fan starts whirring i make sure there is air going on all around it, and it usually cuts out....the noise i mean lol

but theres plenty or air around it, at the moment its on my knee and there is nothing surrounding it..

you knee is not covering up the fan outlet? i have that problem, it is so badly placed? if not then i have no idea sorry...

no its on the side

then no clue...sorry i could not be off any help

Make sure the fan is clean, no weird stuff stuck in it, hoover it out even.
