How to fix noisy laptop fan

Hey guys, well I've been having an annoying problem with my laptop fan. It produces a high pitched noise that is just loud enough to annoy me :/ My room is quiet, so you can very easily hear it. I'm not sure how long it's been going on for, but I've noticed it the last few months. To me it sounds like the fan is starting to wear out, from a fan bearing maybe. I've tried cleaning it by disassembling the laptop, but the noise hasn't changed. Do I need to replace the fan?

Thanks in advance

Hmm gin mate what are the temps doing?? sounds like the thing is working overtime to me.

Try this and post back Speccy - Download < download from piriform.

One thing you can try if the temps are up is to shine a very bright light into the fan aperture and then look into the outlet vent if you cannot see much light then the cooling rad is blocked.
The pic is of a Toshiba but the principle is the same.

I recorded it with my phone right up to the vent, so that's why you can hear the air blowing onto the mic :P I'll download the program in a minute and post back.

Yes I actually got down to that yesterday, I could sort of clean out the fan but I couldn't separate it from the motherboard. :/ There was one screw holding the fan part in place so I unscrewed it, but I could only lift half of it out. Something else was holding it down...

Toshiba Satellite L655 L655D L650 L650D disassembly

Just take note of this Laptop disassembly and repair tips for newbies especially the ribbon cables they have tiny lugs on them that can be really fiddly to use taking out and inserting.

A little something for you too

TAKINGLAPTOPS APART

I always spread out a large whitebath towel on the work top and using cloth or ordinary duct tape keep to be stretchedout fixed down to the work top. This isbecause when removing the sometimes very small screws it stops the screw form beingdropped onto a hard surface where it almost always will bounce and even land onthe floor never t be seen again. Of course if that happens you can scour thefloor with a strong magnet in the case of steel screws the brass ones (thereare some that have brass screws in certain spots) unless brightly coloured youwill not find especially in carpeted floors.

I prefer to use a battery drivenslow speed screwdriver as in pic and leave the screwdriver bits stuckonto a strong magnet or stroke then longitudinally to magnetise them it makeretaining the steel screws so mucheasier especially when replacing them. (If you drop on into the machine youwill need to completely disassemble it again to remove it)

It is also advisable to keep thescrews in separate containers as they will be of different sizes and locations

GENERALINFO

As a general rule of thumb toreplace the thermal compound in a laptop there are two areas to be concernedwith that is the CPU and the GPU (graphics) see pics of them before and afterremoving the heatsink assembly. How you apply the compound is your choice Iprefer to use a cleaner and prepsolution as in the Arctic cleaning kit -http://www.arcticsilver.com/arcticlean.htm and the compound from Artic - http://www.arcticsilver.com/as5.htm but the choice of compound isyours.

To make the job easier because thedies are very shiny I prefer to clean with solution 1 then prep with solution 2 then use a vinylglove and spread a very thin layer / smear on the heatsink and the die – thenadd a tiny half grain of rice size dot of compound the the centre of the die/sand reattach the heatsink assembly. DO NOT apply more than that.

DO NOT over tighten the retainingscrews / bolts

Oncedone and before you reassemble now is the best time to make sure the “radiator”and fan assembly is clear of dust and crud (stuck on dirt).
TIPIf you use compressed airto clean the dust from the fan DO NOTlet the fan spin it is not designed to spin at speeds exceeding what it wasmeant to and will if left spinning with the air blast will wreck the bearing.If the fan is tight to turn then it needs replacing as the bearings are usuallysealed.

Now you might find a screw that is not listed on the other side of the board some of the Toshibas I have worked on have a few hidden screws that are a pain to locate. You may even have to remove that whole cooler assembly, but it gives you chance to redo the thermal compounds eh?

PS Meant to say use these if you do the compounds

Yeah I've disassembled down to the fan, I'll just do the keyboard for now. I'll take a picture of it. I can try the full disassembly tomorrow maybe.

EDIT I'll take the keyboard out, I won't be on my computer for a few mins
