2011 Macbook Pro Fan noise?

Im extremely dissapointed! I've been a PC user for as long as I can remember and I bought a brand new i7 13" MBP about 6 months ago to only be left wanting more....Since day one the MBP has been extremely slow, for many tasks that are super fast on PC the MBP takes for ever...simple things like managing my picture library, opening Preview or loading a PPT..this takes at least 3 times loner than on my 3 yr old Dell laptop.

To make things worst, the battery that is supposed to last 5+ hours never lasts more than 2.5h and now in the past 2 months the fans are ON ALL THE TIME!

I see that many of you are having the same issue and was wondering if you can point me in the right direction as to what to do. I didn't purchase the AppleCare plan as I think that I paid a good chunk of money for a device that should work and doesnt...but if I have to buy it in order to have my $1800 MBP to work I guess I'll do it.

Thanks for your help!

I just got a MBP 13 i5 late 2011. Running normal software is ok. Quiet than my old pc but when it comes to gaming, heat is up so much and noise is very loud...louder than my old pc. The good thing is the game performance is great. The fame rate is up to 49fps with high quality setting and 120fps with low quality setting.

Your Mac sounds like it does not have enough real RAM mmeory for the things you are doing. This means the additonal RAM needed is simulated on the Hard drive, which now must spins at all times, adn generates additional heat, which menns the fan spins up and ther battery life is not as good as it should be.

How muxh RAM?

What are you running?

I run Macbook Pro 13" late 2011: core i5 2.4GHz, RAM 4GB, intel hd 3000 grapgics, HDD 500GB. I think i have enough ram. The game runs smothly. It's just the noise that bothers me

Hi Grant, it has 4Gb in RAM. Im only running PowerPoint, Chrome and Apperture...that's it...Im not sure if I need more RAM on a MAC but I could run many more things on a PC with 3Gb on RAM with no issues at all.

In the last couple of weeks it's getting hotter and the fans are getting much louder constantly...

When looking at the activity monitor it tells me it still has 1.3 Gb of free RAM...

Thanks for your help.

I'm still pretty new to my 13" MBP but absolutely loving it. I use it almost all day and most evenings, desk or lap it seems fine. I can hear the fans slowly spooling if I put my ear close to the keyboard or underneath but otherwise I'm really impressed with the heat management and the fact I can even touch the underside after it's been on for hours!

Only thing I noticed this afternoon is the high-speed spool-up cycle it went through after being on for 7 hours. Having worked with plenty of servers over the years, it's a noise I used to associate with server fan test cycles rather than a laptop, but nothing like an aeroplane taking off. When the fan noise came on (fairly suddenly) I did have a few apps open, system performance did decrease and almost hung for a few seconds.

To be fair, I've moved from a Windows PC and laptop environment to MBP and would not change back. You get what you pay for in spec, looks and usability in my book and it's worth it for what I do.

I have had my 2011 MBP 13'' since September. For about three months I did not have any issues with my fans. Shortly after the holidays I began having issues with my fan. I would only be browsing the internet and the fans would randomly kick on at an abnormally high speed ( on the table, not my lap.) I have the istat pro widget to watch the temp on my mac and the rpm's of my fan. I have noticed my fan always runs anywhere from 4000 rpm's to 5000 rpm's, which is high when you are not doing anything excessive. Like Nori037 it bugs the **** out of me. I wish apple would do something to fix this problem because I did not pay over a grand for a defective computer

Hi. I have the Macbook pro 13'' intel i7 4GB RAM, and it had the same problem with the fan, I solved it by resetting the SMC, just like it's shown in

I don't know if you have exactly the same problem, but I have fixed the problem with the fan noise.

I have the exact same issue, my labtop is brand new and It has this constant hum noise and its constant from the moment that I turn it on, its so annoying bc I just bought it 7 months ago. very disappointed. I dont do much on my labtop just the basics.

I tried taking it to the genius bar and they were very dismissive of the problem, they said there was no issue for the fans and that this constant hum noise was normal ?

IS it normal ?

Thanks in advance!

I think the noises we hear at home when we're in a room and all you can hear is the really annoying fan are different to when you take in to Apple and the noise of the shop is drowning out what irritates you at home. It won't come over the same. My MBP was half the volume of hum before the 10.6.8 update as I think most were. It's a real shame that they are so annoying now when they were pretty quiet before

My MacBook Pro 8,1 was doing the same thing. After the software attempt with apple support. I took it to the Apple store. I recorded the noise on voice memos so I could play it back when it didn't act up in the apple store.They replaced the fan over night. I have AppleCare so the service was completed at no charge. Now it sounds like it should now, Silent.

I see a lot of people here complaining but is there any solution to this problem? I mean, that's why we are all here...

I stated in an earlier post that I discovered the noise to actually be the HDD and not the fan. It was a very low volume whirring sound that was easily mistaken for a fan sound. Even though your could barely hear it in a quiet room, or not at all in a room with any noise, I couldn't take it. My other MBP's made no audible sound until you taxed either the main processor or the graphics processor. Then you you could hear the fan. Even that was not unbearable and it only lasted until the system was back to SOT (standard operating temperature.)

I swapped out the hard drive for another and the system was silent. Problem solved. The HDD that came in the MBP works fine and runs cool. It just doesn't run silent. But it's certainly good enough and large enough to use as a back-up drive in an inexpensive USB driven enclosure.

i understand changing the HDD can probably solve the problem.

But I've did an experiment and i 'm not quite sure what's the problem is, so please help me explain that.

Condition 1: only Safari is open, with stuffs like YouTube, Facebook. NO FLASH GAMES, VIDEO CONVERTING PROGRESS RUNNING throughout the experiment.

result 1:

I use smc to control my fan speed.

Normally, i set to 3332 rpm, quiet, no noise at all, just a very little humming if I close all my house's windows.

Then, I change fan speed to 5689 rpm (just a random higher rpm to simulate high CPU usage conditions). Now, i hear loud noise from my MBP, CPU usage from Activity Monitor: 5% average (user + system).

Condition 2: I play Sims Social on Facebook.

result 2:

After playing for 5 minutes, that same noise that i heard in experiment 1 again. smc shows 5xxx rpm fan speed.

So please help me analyze this.

How does the HDD affect the noise produced by my MBP, under the conditions listed above.

That would be extremely helpful, thanks!

🙂

I have SSD but it doesn't change anything...The Fan goes crazy if I watch youtube video or if I have a some safari pages open but the CPU usage is only at 3-5%...
