Do i need my fan on my Macbook Pro?

[martymar112]

i just upgrade to a SSD Hard drive and my fan is making this horrible noise. is there away i can just turn it off. the reason for the Fan is to cool down the hard drive correct? since my new hard drive does not get hot do i still need it?

thanks

the fan is there to cool the cpu,
more knowledgable people than I can give suggestions for fixing the problem, I don't think replacing the fans is that expensive if it come to that

i just want to know how to turn off the fan for now. i can replace it later but this noise is driving me crazy ha.

I have smc fan control on mine, it shows the cpu (or near cpu) temperature and has fan settings. The slowest I can slow them down to is 2000 rpm.
The fans are easy to unplug when the MBP is opened up, but not having the fans may fry your cpu, my 2011 15" has two fans, and my machine was ok temporarily with one not working, but I could monitor the temperature and fixed it quickly.

The bearings may be loose, or you may have hair/dust on your fans.

If your fan isn't working correctly, you shouldn't use your computer. Replace the fan!

You can just unplug it but your processor will throttle like crazy. It won't damage the processor but you could shorten the life of other components as there's nowhere for the heat to go.

No problem, just tear the fan out.
Make sure to keep the bottom cover off your Mac so you can spray the insides with water to cool it down.

Yes, replace the fan asap. Depending on which type of Mac you have they don't cost much and are dead easy to fix in yourself.

The fan is there for a reason, you risk cooking the CPU and GPU, I'd get a replacement and while you wait for it, don't use the computer.

The computer will overheat and shut down in a matter of minutes (maybe seconds) if you turn it off. You could permanently damage it if it doesn't shut down on its own soon enough. What you want to do is a bad idea. If you can't be bothered to fix it properly bring it to someone who will. A fan's not hard to replace.

You saying the fan is there to cool the hard drive makes me think you shouldn't be messing around in that machine.

I would replace the fan as soon as possible.
Here is a guide I found on Fixit. https://www.ifixit.com/Device/MacBook_Pro_15"_Unibody_Early_2011

download macfancontrol or similar free apps.
Than you will learn within some seconds that even if you don´t HEAR the fans, they always run with about 2000 rpm.

If you switch from "auto"-mode to "manual mode" you can chose any rpm you want - at YOUR RISK.
But if you regard the displayed temperatures of CPU and GPU I am pretty shure you will not be that dump to ignore them and fry within 15 min your Mac … the fans are NOT controlled by temperature sensors but by electric consumption of CPU and GPU - the reason is perhaps, that this will already start cooling BEFORE CPU/GPU get really hot and begin to throttle. First try to open your mac and have a look if there is dust blocking the fans itself or the outlet of the cooling air. If the fans keep running at max, the fan-cable of at least one fan is broken. If the fan gets no commands about at what speed to run (broken cable or so) they run in "urgency mode" at max speed for SECURITY reasons (protect CPU/GPU). The simple philosophy behind is: "Better cooling to much and make too much noise than destroy the main board and provoke a very bad smell of burned electronics."

Exchanging immediately fans if they are not properly working iOS one of the best investments you can do..

Good luck.

As a general rule, if it's in your laptop then it will be needed. Replacing items that are either faulty or underperforming is another matter, but you shouldn't just remove anything.
