Question For MacBook Users...

I'm kinda concerned...I bought my MacBook about a year and half ago and everything was going fine until a couple of months ago (2, 3 months ago to be exact).

Now, my MacBook heats up relatively quick and the fan is running like crazy; it's so loud that I'm starting to wonder if there's anything wrong with it. It doesn't do this ALL the time but when I'm running say 3 or 4 programs (especially MS Word, Entourage, Netscape, and iTunes) at the same time, the Book heats up pretty fast and so the fan runs pretty loudly. I don't know if it's because the memory is not enough? But if that is that case, wouldn't the programs just freeze? I can still use the programs when this happens. And also, when I watch clips on YouTube, it heats up pretty quickly. I don't know if I need to take my MacBook to the Genius Bar at an Apple Store. Should I have it checked out? Any ideas why this is happening? Any suggestions/comments would help. Thanks!  Smile



Peace,
Wes

Just what sort of clips are you watching on YouTube?  scratchchin

The behaviour or the fans sounds generally okay: If software puts high demand on the CPU it will begin to heat up and at a certain point the fans will speed up to keep the temperature within the prescribed limits.

My guess is that you're running at least some programs which cause a certain base load already, so when other applications increase their demand on top of that the total load rises to levels which you hadn't had before.

I'd recommend you to run the Activity Monitor (you can find it with Spotlight or in Applications/Utilities) to find out what the total CPU load is and which processes are the main consumers.

The behaviour of the machine would only be weird if CPU load was low and the fans still sped up nevertheless.

Virtual memory swapping would only slow down your work and cause frantic disk activity, but usually not increase CPU load or speed up the fan(s).

Sounds a bit unrealistic. They usually "just work". Still no absolutes.

The other posters are right. The more processor power you use, the more the fan will run.

If you are using 100% processor, the fan will run all the time.

It is good to make sure the machine is getting good ventilation. Sitting on a blanket / carpet will make it run hotter. Sitting on a cool tabletop allows it to vent better.

It's always worth taking it in, since it's a free consultation.

Make sure you're using it on a flat surface (ie not on your lap, on a bed, on a fabric surface or anything like that) and that the area beneath the case is well ventilated.

My macbook is only two months old, and the fan runs on high whenever I'm using Canon Imagebrowswr to look at or print pix. Same thing happens with videos on the web. I never thought it was a problem.


Never let the facts get in the way of a good story.

The Flash browser plugin currently is rather inefficient - it uses far more CPU performance than it should need to. So when you're playing Youtube videos for a longer time, the fans can indeed speed up because of it.

Lol mine does the same. I got mine right after they upped the CPU speed to 2.16 GHz, would that make it hotter than the 2.0 GHz macbooks? Just wonderin..

I checked it out and the "kernel_task" program or something takes up 120MB already! My poor MacBook only has 512MB  cry  .

I put my MacBook on top of the "cooling pad" thingy with two fans running underneath. Although...sometimes I put it on my lap to type lecture notes.

Is it really free? Mine is over a year old already...the warranty already expired  Sad But if it's free then I definitely wanna take it in for a check up.

512MB is a bit tight indeed nowadays. But it's still not necessarily a problem since much or most of the allocated memory space isn't all that frequently used; Much of it can be swapped out to disk and stay there for most of the time. But there will be a swapping delay once these resources are needed again.

That may or may not actually help much... have you checked what the CPU load generally is?

Right now I have iTunes playing music, iChat, Netscape, Entourage, and MSN messenger running and it's showing about 25% "user" and 30% "system". I don't really understand computer but I'm assuming this is acceptable?

It sounds quite a bit on the high side for basically idling... (even though on a dual core machine the scale doesn't go to 100% but to 200%) You could check the Activity Monitor for the individual loads imposed by the running processes. Or terminate the applications one by one and watch the load go down accordingly.

What kind of CPU does your machine have and what's the clock speed?

I'm assuming this is what you're asking? I'm not good with computer terms and stuff  embarrassed  : 1.83 GHz Intel Core Duo 512 MB.

Sigh, is there anyway to upgrade the RAM?

I have the exact same machine, and experience some of the same issues you have with the fan. For instance, when I'm processing video, both processors will be whizzing away at 75% or so, with the fan blowing like no tomorrow. Just nature of the beast.

So inefficient, I've even had the fan kick in when flash banner ads appear.  Wow!

I just bought the 2GB kit from crucial.com for $65.99 delivered. RAM is very cheap right now. When I first looked at it, the same upgrade was $106.99 a couple of months ago. It fell $14 just in the past week alone. This is what I ordered:

Yeah, exactly. What does the Activity Monitor say about the individual processes and their performance load? (Select All Processes in the popup selector above the list, then have the list sorted by %CPU to expose the main consumers at the top of the list.)

Quoting Foppishbum (Reply 14):

Sure. Your MacBook can manage up to 2GB of RAM (which would probably be a good idea to have - it's not all that expensive any more and a sufficient amount of RAM is the biggest speed booster that can be had, even more so than a faster CPU!).

Apple has an illustrated how-to guide here: MacBook: How to install memory

It's best to buy RAM with guaranteed compatibility to your MacBook - don't go for the absolute lowest price and be on the safe side.

Not that there was a major risk involved, but if you haven't done so recently, take the opportunity to make a backup of all your documents and personal files. Preferably back up your entire home directory so your application preferences and other important data will be secured as well. Modern computers are quite reliable, but especially laptops can always meet unfortunate accidents.

Okay...I hope I got the right information. The top 6 varies among: iTunes (~15.13MB), kernel_task (118.56MB), Entourage (30.82MB), navigator-bin (26.59MB), WindowServer (17.41MB), and MSN Messegner (6.63MB).

I have no idea why there is "kernel_tasks" and "WindowServer", I don't think I have networking or anything that requires "WindowServer".  Sad

Sorry...lemme try it again. Hopefully this time I got the right info...top varies between iTunes (5.80), Navigator (2.50), kernel_task (1.40), pm_tool (1.10), WindowServer (1.00), and Entourage (0.80).

That's significantly less than the 55% you've reported above. Have you selected Show All Processes?

I should have gotten all the processes  Sad But now I'm not sure. My friends over here suggested me uninstall every extra programs like GoogleNotifier, GoogleDesktop, Adium, Palm Desktop, etc etc and reinstall the ones I REALLY need to use. It turned out that after doing that the fan doesn't go crazy frequently anymore. I don't know if it is because I had too many other programs running in the background or what. I'm still having trouble with MSN Messenger though...it's not stable.  Sad

It's the popup at the right in the tool bar of the Activity Monitor. I think by default it's set to My Processes, which would not catch everything going on in the background. It could account for the difference in individual and total loads.

It's always best to know what exactly the problem was, and Activity Monitor can help you find out.

So what's the load now after uninstalling the background stuff?

Quoting Foppishbum (Reply 21):

Hm. I can't help you there... but maybe they have a newer version than the buggy one you've got. I've also heard about alternate applications which can connect to MSN, but I never had the need myself so I didn't really investigate.
