My late 2009 Imac (Intel) has the fan running on high almost all the time. I have done the hardware test, the fan temp checks etc, all are normal. It was suggested that I up the RAM from 8 to 16 (the limit) any ideas if this will do the trick? This computer runs excellent otherwise except for the highly annoying fan noise?
View 2 RepliesMy iMac (intel core duo) after a hard drive replacement seems to be running the fans at a high rate of speed. Usually just a few minuets after startup. Before the upgrade they were almost silent and now they are very noticeable. I need to get taken care of or just a result of installing a larget hard drive?Â

Both of my fans are running at the max 6200 RPM and have been for well over an hour. My CPU is over 65% idle, and none of my processes are over 20%. My HD Temp is 38 degrees and my CPU temp is 72 degrees. I don't think my fans should be running this high considering the computer is doing so little work.
View 24 Replies View RelatedMy macbook fan doesn't stop running on high power (6700rpm). There is no process generating high CPU load (checked with iStat), and the macbook is on a normal desk. I've also made a SMC reset, without any improvement. I thought about reinstalling Mac OS X, but the fan already starts when I switch the computer on, so not sure if it's the OS. It's really annoying to hear the fan running all the time.
View 24 Replies View RelatedLast summer my MBP 2.3 GHz C2D was heating up so much, you barely could touch it. So I decided to give it a little hardware checkup. Finding the fans completely stuffed with dust
But after a while i recognized that the fans went on high rpms (around 6000) already at startup and did not lessen anymore. I do not have any high capacity processes running and the temperatures are not just not warm buth rather chilly, so no need for high fan speed. Now I want to solve this problem as well but seemingly nothing will work.

Recently my cooling fan has been running at what sounds like full speed and never resumes a quiet speed. I have not used it any differently than I have since I bought it (in January) and have not really added anything to it in the way of downloads.
View 39 Replies View RelatedI have a Blackbook, it's about 3 years old now and the fan speed has increased to a very high level. There aren't any programs running in the background, this just simply happens when I leave the computer on. I'm assuming it's because there is dust buildup on the internal parts, but it's odd that it progressed from being fine to the stat that it is in today in the matter of days. Is there a way to clean the inside? Apple technician to have a look at it?

So, I just noticed that when I have my MacBook Pro in High Performance mode it emits an high pitched noise when the fans are running around 6.2k RPM and the CPU and GPU is around 63c. The noise follows the speed of fans, and at idle the noise is gone.
I have uploaded a video of it on youtube here: http://www.youtube.com/watch?v=HioRgTNpNRA
Recently my computer has started to run slowly in things like games and the only time that it runs normaly is when I restart my computer and then it gets slow again after about 5 min. My computer's cpu has been running at about 77-87 deggres celcius. Is that the normal running temps of a 2010 13-inch macbook pro? I have asked on some other places and they have said that it is dust in my comp that is heating the cpu up and therefore making it run slower.

I noticed my computer was getting hot to the touch, and warming my computer room significantly.. So I checked my temperatures for the system and noticed everything seemed normal except for the Northbridge Chip (127 C) and Northbridge Heat Sink (62 C). I am running no applications, CPUs are basically idle. Â
I am concerned that this temp is WAY higher than it should be, using Google, I found that many users were concerned that 80 C was too hot for the northbridge when the 2009 Mac Pros came out. What should my course of action be?Â
Is there a hardware button to reset everything back to factory without reinstalling Mac OS X?Â

I have a MacPro 2.66 quad-core intel. 4gb ram. I have a hard-drive from my old Powermac that i upgraded to 10.5.5 for this computer. Everytime I put my computer to sleep, and then wake it back up. The fans spin up to maximum speed and all the fans are running really loud and then after about a minute all spin to normal speed.
I don't have any other flaws except for this. Why could this be?
Is it possible to run the a MacPro under bootcamp all the time using a high end Nvidia or ATI graphics card?I would like to use the MacPro as a gaming PC.

The computer is especially slow on Safari where it is faster on my MacBook pro.
View 4 Replies View RelatedI bought my first Mac, a C2D MBP 13". I really love the machine. But I'm experiencing this particular issue of having high cpu load of up to 80% while on W7 Professional bootcamp even though I'm not running any graphic intensive programs.
Specs: 2.4Ghz MBP 13" (The recently refreshed model)
Windows 7 Professional 32bit (MSDNA Edition)
Upon successful installation of W7, I inserted the OS X disc inside and the bootcamp drivers installed successfully. So I'm quite sure the drivers are okay. Being a DotA lover, I installed WC3 on my bootcamp. However, I realise that whenenver I'm on windows mode, the machine is very laggy. I even have problem opening a browser when I alt tab out from WC3. Is this normal? Even when idle, the cpu load on the processor jumps from 1% to 47% randomly. Just fluctuates randomly. I'm quite sure my Windows Security Essentials is not doing any scan btw.
I replaced my logic board and couldn't get my Macbook to start, but last night I replced the RAM with the original one that came with my Macbook and it started up, everything is working fine, but the Fans are running high I can hear it loud and the keyboard light are not working, but the keys works fine. I tried the reset options but nothing happens.

I just bought the macbook 13" (white casing) today and the first thing I noticed when I turned it on was the fan, it was extremely loud!! I let it run for awhile and it was still constantly loud. Then I tried rebooting twice and still the same problem. My room is only around mid 60F. Is there some function I'm supposed to turn off? Or did I get a lemon macbook?
View 3 Replies View RelatedThe other night, my MacBook Pro's fans started running at high speed when the computer was asleep. Loud enough to wake me up. And this just kept on going until I finally decided to turn the computer off. Is this normal? Is this anything to worry about?

This is my first post, and I apologize as it's a little long. I just wanted to get the whole story on the table and clarified.I've had one of the new Aluminum 13" MacBooks (2.0GHz C2D) since Christmas Eve. A few weeks ago, it accidentally fell off my desk at work (not a far drop , but far enough for my heart to stop for a few minutes) when I got tripped up in the power cord under the desk.
For all intents and purposes, the MacBok seemed to work fine. I had one of our IT staff, who happened to be a trained Apple repair tech, take a look at it; the only real damage was that the display hinge had been knocked a little out of alignment. Just ot be on the safe side, I took the machine to the Apple Store, where they told me not to worry about attempting to get the hinge fixed (because I'd be paying a lot of money for such minor work), and the Genius sold me a hardcover plastic Speck case for the MacBook.
While the Speck case certainly looked nice and madethe already sturdy laptop feel sturdier and "protected", I was a little concerned about the amount of heat the machine was giving off within the case. On Sunday, I unplugged the machine from the MagSafe charger for a few hours and left it closed in sleep mode. When I woke it back up, the fan on the left continually gave off some sort of high-pitched whine whenever the computer was in idle mode.
I Googled, searching this site and others, and read about the "CPU whine" in the previous generation MacBooks and MacBook Pros. I also saw where a few people with new Aluminum MacBooks were having this same issue or something similar:
URL
It seems to only make the noise when the computer is running off of the battery - plugging in the MagSafe charger makes the noise quiet 85% of the time (I've found that plugging, unplugging, and replugging will not stop the whine from occurring).
I tried installing QuietMBP as was recommended in some posts, but the only setting that will stop the computer from whining is the "highest" setting (that is, allowing the processor 0 seconds of idle time), which causes QuietMBP to eat up 30% of my processor usage in Activity Monitor and to start the fans going (and, presumably, to significantly lower my battery life).
I don't know whether all of this was the result of the MacBook falling, from it overheating in the case, or something that "just happened". I set up an appointment with the Genius bar for today at 4 PM, but Idiscovered another odd occurance when I set up a new account for the Apple Store (rather than give them my password)
The noise never happened under the new account. Never. I left the machine idle until any and all initial processes were done. No noise. I checked Activity Monitor for stray processes. None. And no noise.
Now I'm bewildered. Could something have gone wrong somewhere in my account, leading to a corruption of a power management utility or process? I'm not canceling my appointment, but I am going to try a few things before I leave. I've already repaired disk permissions, and I'm about ot reinstall the 10.5.6 OS X combo update. Should I try to reset the PRAM too? What other options should I be looking at?
Or should I just wait, and let the Genius Bar folks look into it? As a note, I'm aware I may have to pay for any repairs because they may or may not blame them on the MacBook having dropped (despite two to three weeks passing between the fall and this issue arising), and I'm okay with paying for reapirs (though I will try my best to argue my case, of course).
I've had an iMac for just about a year and over time I guess I just didn't notice but the machine always ran very quietly. At the same time the back of the computer would heat up so bad that it would nearly burn my hand if I left it there. Well last week I decided to upgrade to Lion from Snow Leopard and when I did the install failed and froze up the hard drive. I took the computer in to the apple store and they determined that it had to have a new hard drive installed because the old one (only a year old) had a physical malfunction (was broke). So anyway I have my iMac back and get it started up, backed up from time machine, and then finally get Lion istalled - and now all of the sudden I notice that the fans in the computer are CONSTANTLY blowing - I can hear them spinning and can hear the air venting out of the back of the computer - and the computer is STILL really hot on the backside of the screen. Â
So now I am wondering if the originial problem was the computer heating up and if that may have broken the otherwise good hard drive? Also now that I have a new hard drive - should I be concerned about the fans being on ALL the time? I mean they never go off. Even when I leave the computer for hours and come back to it and the screen is asleep the fans are STILL buzzing away at top speed. Here is the stats on the computer at the time that I'm typing this note - there are no other programs running than Firefox and Mail. Also - I don't know what the optical drive is exaclty - but if it's the DVD drive (superdrive) - there is nothing in the DVD disc driveÂ

Returned home this evening to hear my iMac fan making lots of noise, upon checking it was the HDD fan that was operating at 5500rpm. Both other fans were normal. Ambient temperature was 23c and HDD temp was 36c. Normally it's almost silent. It's a late 2009 21.5" base model that has never had an issue in the 23 months that I have owned it. Any idea what the problem is has it gone bad? I restarted but the problem remained I had to shut down and restart to get it back to normal. On another note how do you clean off the dark grey blotchy marks that have appeared at the top of the screen. They don't appear to be on the glass. They started in each corner now they span entire screen top.

I have noticed a lot of disk activity reading and writing, it maxes out in bursts up to a couple of minutes at a time and overall seams to be reading and writing a lot of the time, with no processor activity at all. There is no obvious culprits in the activity monitor but terminal displayed large number of read and writes for mds, but spot light is not indexing (no dot in Mag glass) and this has been happening from months now.
Possibly longer noticed it when recieved replacement drive due to crook seagate, may have been doing this but could not hear it. Running last Snow Leopard on iMac 27 mid 2011 i7 custom with 8 gb of ram. also should note this unit has had load of issues Bad Ram, some software problems would not sleep (software) none of which have ever manifested on any of my other (older) macs. Also have noted that this drive activity does seem to coincide with using safari on occasion??
