Macbook Pro grinding fan noise

Buzzing noise is when the fan needed cleaning.

If its grinding, the HUB of the fan is already destroyed, there is no help via cleaning IF it is in fact grinding.

contact Apple for replacing the fan assy. 😊

Saw your video, yup, fan is destroyed.

Do you use your mac in a dusty place and/or have lots of pet fur or fuzz flying around? Laptop fans act like little vacuum cleaners of the air and gather such fluff.

Having repaired laptops for years, when someone brought in a laptop with a grinding fan, I would ask them "do you have a pet/ cat / dog?"

They would says "yes, how did you know that?" 😊

your crashes are ANOTHER ISSUE....... however there is no doubt that your fan is kaput

Your MacBook Pro is the same model commonly plagued by the problem described in this Apple Support document:

MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video

This is not something you can fix yourself. Please have Apple assess it in accordance with their procedures.

First open the MBP and inspect the interior, especially the fans. Run an Apple Hardware Test.

You may have to use OPTION and D keys to start it.

CPU temp: around 40-60°c

Fans: around 2000 rpm

The above are normal values.

The fans can be replaced independent of the logic board. I find you resellers advice suspicious.

It is not likely that the crashes are attributable to the fans. Next time a crash occurs, copy the crash report and post it.

Ciao.

Sounds like your fan(s) has a warped spindle which can cause blades to break or wear on the side, it also could be the result of a object or dust.

The machine is not getting cooled properly and if this has gone on for some time then the damage is irreversible.

Fans can be replaced and the cooling fins cleaned, this is the cheap route to go first, then if the hardware problems continue it's likely best to buy a new machine instead.

The graphics card is the hottest item, it tends to go first when not cooled or overheating.

Mac's need a occassional internal cleaning, but nobody or even Apple I think even does it. 😟

What you should consider having done:

1: Cleaning inside of the machine of dust

One can greatly extend the usable life of their computer if the dust is routinely cleaned out of the machine, especially the cooling fins where it gets clogged at.

Inquire with Apple or Apple Authorized Repair about having the dust cleaned out of the machine at least once a year and determining from that how often to have it done.

Do not open the machine unless it's one of those machines that are user service allowed or you will void your AppleCare/warranty.

It's making noise, it's broken.

Take it in for a fan replacement and have the cooling fins (behind the fans) cleaned.

Still have trouble? Consider the logicboard replacement.

If Apple only offers a logicboard replacement (includes fans) and it's too costly for a older machine (older than 3 years), then buy a new one.

Transfer your data or backup beforehand.

My computer is not working, is my personal data lost?

Most commonly used backup methods

You need to use your original Applications Install DVD. With that disc already inserted, start your Mac while holding the D key.

Your Mac cannot use the Internet version of AHT.

Apple Hardware Test is insufficient to diagnose the Intermittent black screen or loss of video problem and is likely to indicate "no trouble found". Apple has a specific diagnostic procedure for the problem. This is not something you can fix yourself.

As far as I know Apple has continued to replace logic boards on your MacBook Pro model at no charge, provided their diagnostic procedure confirms that the GPU problem is the cause.

When you asked about this problem some time ago this was my response:

... you absolutely have the exact model MacBook Pro and the exact error that is known to plague it. I would be very suspicious of the "Apple Premium Reseller's" conclusion that your Mac is not affected by this problem.

You replied:

I think the reseller just compared the computer's serial number to the ones affected.

That is not sufficient to conclude your MacBook Pro is not affected. Stand your ground, get another opinion from another authorized Apple service provider (not including the many opinions you have already received here) and get it fixed. This is not something you can fix yourself. You are only likely to break something else, giving Apple justification to refuse warranty service.

The OP I believe has a 2010 MBP. I tested on my 2010 MBP, both on the Snow Leopard partition and the Mt. Lion partition and both times the MBP would bring up the AHT holding down the D key. It did take over a minute to bring it up on the Mt. Lion partition whereas the Snow Leopard partition was about 10-15 seconds. Perhaps a little more patience is necessary.

Ciao.

My suggestion for the AHT was sriclty to see if the fans were faulty.
