My mac pro fan seems loud

OraliusJohnosn · #1 January 28th, 2008, 03:19 PM

It's a constant drone. Also its a bit of a hassle since i'm recording music.

quad core 2x 3GHz Intel Xeon
4 GB 667 MHz DDR FB-DIMM ram.

i keep the computer running most of the day, is that the reason why? my friend with a dual core mac pro seems to run nearly silent, and most of the people i see in other forums online say that they are nearly silent.

Anybody have solutions for this?

A few things will make a difference;
how is the air circulating around the Mac? If it's in a corner where it can't circulate freely, it will be more hot, and run louder. Also ambient temperature will make a difference on that, and other differences are what applications are running, how much ambient noise is on etc (there is a difference between 5 and 35 dB...)

its 3 feet from a corner and under a desk, but i don't think its that circumstantial. it kicks in loud when i start it up. its cold in my apartment we don't have heat. generally it doesn't differ if i have one program open or many programs open. what do you mean by "how much ambient noise is on"?

i downloaded some software that is saying that its 135° F in the computer. I'm not sure why its so hot. my apartment doesn't even have heat. its frustrating cause all the other threads i've found on the internet are a bunch of people saying their computer is silent.

someone help

also i just had another realization. everytime i shut down and turn the computer on right after, the power button lights up white, then it makes a loud fan noise as if it were going to start up and spin the fan, but instead of slowing down after a few seconds the fan keeps spinning, and it doesn't start up. i have to push the power button so that it goes off again, and it starts up successfully the second time

Yup, same problem here. I'm not too bothered that my Mac Pro runs hot when in use, but after closing all apps and walking away, the fan will still be coming on and off loudly the next day. The machine is on a wooden floor with plenty of space around it. I also have this curious booting behaviour, whereby two presses are required.

Any help would be appreciated.

I also have the same 2 problems with my Mac Pro. The fans run loudly on and off, mostly loudly. I just reinstalled my system to clean out unused apps system prefs to see if that would help, but it didn't. Even when I'm not using the computer, the fans run loudly. I also have the problem where i have to push the power button a second time to startup. Any help would be appreciated too. Thanks.

I found this software that allows you to raise the default fan speeds. Seems to help for me.
