and it's major surgery to get at the fan and heatsink. doable but major dissassembly. question is, what is normal fan cycling on and off? can i leave it and live with the noise, or will i kill the fan if i don't clean the heatsink? and can i assume the laptop will shut itself off before it overheats? --fj
i have a 5 yr old HP dv1432us laptop, works great but lately the fan seems to be running a lot.
i turned it over and put a house vacuum on the fan intake and a few little dust bunnies came out. the fan is not running constantly like it was but it is still cycling on and off pretty regularly.
i unscrewed the 3 screws on the "plate" around the fan intake but the plate would not come off.
anyway maybe it's just normal (the CPU is running at about 50%) but after 5 years seems like maybe the CPU heatsink should be cleaned? on the other hand, i don;t want to wreck it. any advice? --fj
