    Recently my MBP has this really loud fan noise. While checking the fan speed, I noticed the right fan is sometimes stuck at a certain speed while the left fan is at a higher speed (left fan is at 5000 rpm then the right fan is stuck at 3700 rpm).

    I've read a lot on other forums about the fan noise. Anybody else experience this?

    Happens quite a lot, actually. The left fan is intended for the CPU while the right fan is intended for the GPU. It is normal for the left fan to run faster because the CPU is used a lot more often than the GPU.

    To dissipate heat more, I use an application like smcFanControl to regulate the fans and make them both run at the same speed.

    I bought a Coolpad for P1,700. I was too tired of hearing those fans go off... nakakapikon. hehehe.

    Now when those fans run, I turn on the Coolpad, (pre-emptive strike even better), and within a few minutes, the fans turn off.

    Also not a good idea to place the MBP on a flat bed as the mattress / blanket tends to block the exhaust vents of the MBP, which makes the fans activate SOONER.

    Try the Coolpad thing. It's worth the investment!

    it's covered by the limited warranty/applecare. both the fans on my mbp have been replaced already. (thank you apple by way of digital walker v-mall).

    it's just about time for your MBP's fan to act up. if it's still covered by applecare, use it. if not, the grinding fan noise may be fixed by either a) cleaning the fan, or b) having the fan replaced.

    the right fan that i ordered is arriving in a few days. cleaning didn't help.

    great! the mbp's right fan is spent, so it's replacement time. i'm using the mbp like a desktop (clamshell) the way i used to with your mac mini. i miss the mac mini's cooling because now, i'm monitoring temperatures and fan speeds on the mbp - something i didn't do with the mac mini.

    Same here. I had grinding noise from my fan on the Macbook Pro. Sent it to Digital Hub virra mall and they replaced it for free. Great service. :)

    the guys at the repair center told me that it would take 21 working days to repair the fan. 21 freaking working days? wtf? do any of you guys know who i can contact just for a diagnosis that they can do within a day. the if any parts need replacement, then i can just order and wait for it to arrive before having it taken in to have it fixed. its really sucks that all the apple centers here do not have the spare parts and have to order it from wherever.

    i never would have thought that apple products would show signs of problems so early into its life. none of my previous PC's have had any major issues.
