ScreenSaver fan noise

[Alix]

hi,

i have a macbook and the fan is bit noisy sometimes. Specialy when i use screensaver it runs for a while and after about 10 mints the fan is getting very loud, to much noise. The screensaver which i use r Time machine and lotsofwater.

is this normal? is there a solutions for this problem. I have upgraded my macbook to 4 GB.

excessive fan noise most likely means that something is eating up a lot of processor power. might be the screen-saver, might be Time Machine, might be some third process. Only way to know is to use activity monitor while it's happening, or to use unix processes (like top) to monitor your processor usage for a bit.

and please be a little more careful with your typing; 7 errors in 4 lines is a bit much, and I almost didn't answer because of it. Either you're typing in a big hurry, or you're using the standard chatroom 'is-cool-2-write-bad-inglish' style thing, but either way, don't. it's fine when you're mucking around with 12 year olds, but not a good idea when you're asking for help.

thank for you replay TW,

Wel, englisch is not my native language. I am traying to type correct as possible and i was in a hurry indeed.

No, you did understood my question well. Unfortanly your answer is not a solution. I did used Active Monitor to monitor all of my process. I am 100% sure its the screensaver that takes lots of processor power. i searcht on google for a different kind apps that kan reduce the power of cpu fan, like iStats application.

Is there an application that can reduce the of cpu fan?

What screensaver are you using? Use one that came with your mac or just let it blank the screen. CPU usage differs a lot between them.
Don't try to control the fan it runs because otherwise you would overheat the computer.
And a small tip fill in your location in the forum, then people will see that you are from a region which doesn't have English as it's native language and hopefully be a bit more lenient.

You shouldn't reduce the fan speed, if the problem is the software (the screensaver) that you are using. The fan is running faster, because the processor is under more load. So, it runs hotter, and the fan runs faster. It's just doing its intended job, which is to keep the processor cooler. If you circumvent that, then you risk damage to your computer because of overheating.
A screensaver that uses too much processor is not really saving anything.

So, I will recommend that you choose a different screensaver.

I have tried two screensavers, Time Machine and LotsOfWater. Time Machine screensaver it come's with mac os x leoapard 10.5.* , with this screensaver the cpu gets all crazy. And screensaver LotsOfWater, i downloaded from internet its a freeware screensaver and with this screensaver i have the same results.

I will try other screensavers.

Thank you for all of your replays.

what machine are you using (you said you had 4Gb of ram, but you didn't say how old the machine was, or give the processor speed). also, have you recently done any major software upgrades? if the system is reindexing spotlight while the screensaver is running, that would dramatically increase CPU load.
