Noisy fan after a few minutes start up
Yeah. i had this problem too. the fan is noisy because it is garbage. it needs to be replaced if you want to get rid of the noice. you moving the laptop wen the noise first started is just coincidence. the heatsink is fine, but the fan itself is poorly made. The ball bearings get loose and so the fan doesnt stay in its vertical plane and it kind of shakes a little, thats why it makes the noise. if you open it up and turn your laptop on, and wait for the noise, you will notice that if you push down lightly on the center of the fan, the noise goes away, because you are creating pressure at it's center of gravity point which makes it stop wobbling. you wont see the wobbling with the naked eye, because its much to slight to see, but its definatly enough to make that annoying fighter jet take-off noise..
as far as the noise, thats the sound it makes when something is wrong with the battery (if you ever drain it all the way down and try to boot it, it will make the noise) kind of messed up noise in my opinion, but its not a big deal, as long as it doesnt repeat.
for the fan, you dont need to replace it if you dont use your laptop a lot, you can try to keep your laptop cooler to keep the fan from turning on also. i suggest one of those USB fan pads that you put under the laptop, or a thermal pad, thermapak makes one for $30 i think, and it drops temps by 6 degrees celcius they claim, i dont know exact numbers but if def helped me. you can also try to put something in the back to keep the back elevated (where all the heat is) and the fan wont spin as much.
i know with desktop fans that get lots of use, noise is the 1st sign of fan failure to come, but ive been using my laptop with that god awful noise for about 4months now, and its still alive and kicking.
