Mac Pro fans all of a sudden running extremely loud!

I restarted my computer routinely and when it booted back up the fans started running very loud. They have never run this loud before.
I reset SRC and PRAM as well as replaced the power cord and cleaned the dust out. I also checked that there were not any programs running at high CPU. Nothing new was installed on or into the computer. The computer is not running hot.
I don't know what else to do
The loud fans does not affect the performance of the computer but it's a work from home computer and I need these fans to quiet down!!
This is a MAC pro 1,1 running OS 10.7

Readers have reported "all fans" went to high speed, but on closer examination it sometimes turns out that the graphics card fan, all by itself was making all that noise. If that is the case, the prognosis is very different.
The side door is not interlocked, and can be removed with the Mac Running to determine the exact source of the fan noise.
Caution: The European Commission has determined the anyone living in Europe is not smart enough to keep their fingers out of the plastic fans used in a Mac Pro, so they have been banned Mac Pro silver tower from sale in Europe for over a year now.

Mac Pro Fan Problem

Hi, I have been having some problems with a Mac Pro I have been working with. At the Start-up the Fan goes to top speed and once it logs-in the fan is still pretty loud. I've checking the Temperature of all the computer parts via a Temperature Diode, and its normal and not high. After searching the internet for hours looking for posts that were for the Mac Pro and not for the MacBook Pro (which comes up in about all the searches using the words Mac Pro Fan Problem) and I found some software all of which is not for Mac Pro's. Is there any application I can run do reduce the RPM of the Fans, Reset the Fan Speeds to only turn on when it get hot, or something along those lines.

Thats odd, seeing as Apple have it listed in the Support article:
To reset the SMC on a Mac Pro:
1) From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
2) Unplug all cables from the computer, including the power cord and any display cables.
3) Wait at least fifteen seconds.
4) Plug the power cord back in, making sure the power button is not being pressed at the time. Then reconnect your keyboard and mouse to the computer.
5) Press the power button to start up your computer.
It does exactly the same thing as the SMC_RST button, simply by removing all power from the system. I would assume the reason for this would be that the SMC settings are stored in RAM, which is erased once the power is removed from the board, hence the minimum 15 secs wait which gives time for the capacitors in the power supply and system to discharge.
So yeah, it does do the trick, or has done for me in the past a few times.

What do you mean it did not work! What were the results of the diagnostic tests?
Have you contacted your ISP to determine if the problem is on their end?
Have you changed your router channel? Sometimes this resolves wireless problems.

Macbook Pro 10.6.8 - 4GB started running extremely slowly.

All of a sudden my Macbook Pro 10.6.8 - 4GB started running extremely slowly. I verified the disk and got an OK. I have plenty of memory. Any clue?

I do need to learn how to use the communities...sorry. First time.
I do have lots of free disk space though.
The problem seems to be solved, after a whole day searching for help on the net.
I read somewhere to check my Console.app for repeated information. Then I saw my Mackeeper antivirus was sending the same message every 5 seconds for the last 15 hours. Thousands and thousands of the same message. I turned off the Real-time Protection, restarted the computer and all is fine. Just can't believe it.
Where I live it is kind of hard to get assistance.
Tks for your help.

The beeping sound when dialing a number suddenly got extremely loud.

The beeping sound when dialing a number suddenly got extremely loud on my iPhone 5. I have read that it can't be turned off unless you mute the entire phone. I have turned off all keypad sounds. How do I adjust the beep volume back down to normal?

I just recently started having the same problem a few days ago. My phone has always made keypad noises when dialing, but now they are EXTREMELY loud, almost to the point it is uncomfortable when you have the phone close and dialing. It is driving me crazy and I can't find any fixes.
**Edit** I just got super frustrated and restarted my phone 3 times in a row. After the third hard reset, my volume is back to normal. Give that a shot.

Why does my mac pro fan run at high speed?

My Mac Pro cooling fan started running at high speed. Tried all the shutdown and restart options but didn't help. Suggestions?

The fan runs if something is overheating or if a sensor has failed or there is a problem with the SMC. So, reset the SMC - Intel-based Macs: Resetting the System Management Controller (SMC). If that does not stop the fan from running then check for a runaway application:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
If the problem still persists then create a new admin user account, logout of your account and log into the new account. See if this fixes the problem.
If none of the above help, then you may have a hardware issue such as a defective sensor.

Mac Pro Fans run extremely high!

Hello,
I'm a video editor working within Adobe Premiere Pro CC, and I edit all kinds of footage from DSLR all the way up to RED 5K. I have a Mac Pro (5,1), 6-Core 3.33Ghz with 32GB of DDR3 ECC 1333 MHz RAM. Also in there is a GTX 770 Graphics card with 4GB on board RAM, and a RAID controller.
The problem is that my system fans are CONSTANTLY kicking up to high gear. Whether I'm doing intensive or unintensive work with any kind of footage. It's always within premiere when they kick on. If I put the system to sleep they all go back to normal, but usually kick back on. It is terribly frustrating.
My system is out in the open, plenty of vintilation, and relatively dust-free.
Recently swtched graphics cards from a Quadro 4000 to this GTX, thinking the Quadro was the culprit, but the problem persists.
I've attached two screen shots of SMC Fan Control before and after the fans kick up to full speed. I don't know anything about the layout of these fans, or what does what. I also can't seem to run Apple Hardware Test to see if everything is fine...I try pressing the D key when booting up, but it just regularly starts up. Any other way to test the hardware?
I realize the graphics card will heat things up a bit, but this still seems abnormal. Can anybody help me troubleshoot? Or at least provide an explanation of the fan layout of the Mac Pro, or list some recommended fan speeds? I just can't seem to figure this thing out.
Thank you so much.

Thank you so much.
It does look abnormal, especially if Activity Monitor doesn't show any processes using much of the CPU's capability. Keep in mind that going full blast, your CPU can show up to 1,200% usage in Activity Monitor (six cores, two threads each).
First, we both have the same Mac Pro with the same amount of RAM. Based on Temperature Gauge (from the App Store), the intended minimum and maximum speeds for the fans are PCI - 750/4500, PS - 750/2800, Exhaust 750/2800, Intake 600/2800, BOOSTA 800/4000.
Working up, the Intake fan is at the bottom of the front grill. The Exhaust fan is at the back end at the same level. You've had the processor tray out. Inside the processor block (the box behind the DIMM slots with horizontal fins) is BOOSTA. There'd be a BOOSTB if you had two CPU's. Those three (or four) fans cool the CPU and RAM. Above all that is the PCI fan, which is set in a bit from the grill and, for some reason, doesn't fill it's space at the front so, theoretically, the air could blow into the PCIe area, make a U turn around the right side and go back through the fan again. Finally, behind the optical drive bay is the PS and the fan is at the front of the PS. There's also a fan on the video card, and I've never seen a monitor which could show that fan's speed or temperature.
I keep an eye on smcFanControl's temperature reading in the menu bar and when it heads north of 100ºF I start going to one of the higher fan speed settings I've established. That's probably being over-cautious but I like my Mac Pro. And if the fans can't do the job, it's time to blow the dust out, and that includes the dust inside the video card.
Hope that helps some.

Mac Pro Fan runs at full speed!!!!!

Just set-up my new 2.66 Mac Pro.....added an additional WD Raptor 10k rpm drive and was psyched to use my new heavy iron. I was shocked at how loud the fan noise was!!!!! Upon initial boot it ran full speed (louder than my old 2.7 Dual PowerMac) until I turned it off.
It was definitely not "quiet" as people have mentioned.
I remember all of the logic board issues with bad G5's in the past and am wondering if I have a dud. Anyone else experience the same issues?
-JK
2.66 Dual Mac OS X (10.4.7) 1 GB ram

My 10K Raptor took a week to 'settle in' (or get burned in) and it did seem to cause a hum from the case. Took out the Raptor, no hum or vibration. I also made sure it was seated tightly, and moved it to slot #4.
I ran a 6 hr ZoneBench 511MB test file 30x using 50 "zones" which gave it a good workout. I then ran Disk Utility Erase and under options, chose 7-way write (took a couple hours was all).
Might want to read the review from SilentPC on the 150GB Raptor series.
New Revision, New Noise?
I was ready to put the Raptor in an external case or something at one point (and people probably remember my posts, was a little over a week ago) but someone else told me to "give it time" and just give it a thorough series of tests (like zero the drive at least once). I always load a drive with large disk images when I first get it before putting it to regular use.

Mac Pro fans run full speed after installing Solid State Drives

I recently visited the Genius Bar at my local Apple store because my Mac Pro's fans were running at full speed after installing 2 solid state drives. The genius told me that it was because the drives themselves are so small they don't touch the metal tab on the motherboard that reads the drive's temperature, so it defaults to running full speed. Does anyone know how to fix this problem? I've tried smcFan Control but it doesn't let me set the actual fan speed. I'm getting 5200 rpms on my Boost A and B fans, and this causes an insane amount of noise. Can anyone help?

Which model Mac Pro?
I have an SSD in a 2009 (MacPro4,1). I removed it from the 2.5 in stamped metal can, and just installed the bare circuit board onto the SATA connector. It does not make any contact with the metal tab below the SATA connector. The only trouble I have is that Tech Tool Pro says its temperature is not optimum when it does disk tests.

Mac Pro fans run at max speed with no load

I recently picked up a Mac Pro 12core and it's been working amazingly well for the past few months... in the past day or two though the fan has been ramping up to maximum and staying there. When this happens there are no processes taking more than 4% CPU and the system is never less than 99% idle. Resetting the SMC controller solved the issue for about 8 hours overnight, but when I started using the computer this morning the fan ramped up about 15mins into using it.
The temps (in degrees C) around the mac pro: (collected with iStat Server):
CPUs: 23,22
Ambient: 23
HD Bays: 23,25,24
Mem Banks: 22,21,25,25,25,27,27,22
Northbridge: 27
Power supplies: 33,36
As you can see, nothing is hot... I'm not exactly sure how to calm it down. Nothing is working any differently than it was, it's just VERY LOUD now where it was whisper quiet, haha

I did order it from the Apple Refurb shop and I think it'd fall into that timeframe (got it early November), but I was kinda hoping for some things I could try on my own before shipping it out?

Macbook Pro slow all of a sudden

My mid 2012 Macbook Pro has recently and suddenly become cripplingly slow for no obvious reason. I normally have Chrome and firefox open at the same time and they both run simultaneously very smoothly, up until four or five days ago. Now, launching any application is far slower than it used to be and I see the spinning beachball of death far too often and for the tiniest littlest things, like if I right click a link or something the little options bar won't come up until the beachball has stopped.
Watching videos on youtube is almost impossible as the video lags at times for no reason and the sound will keep going but the video will stop and all i'll be able to do is move my mouse. Or sometimes the video just stops all together. This is with a FULL buffer bar! While scrolling down webpages I am also met with lag a lot of the time. It has made my laptop unusable at times. I have tried reseting the SMC and PRAM to no avail. And If I shut my laptop lid and leave it on I come back to the fan running very loudly and the Macbook being very hot even with nothing running. I updated my software about 2 days ago after the slowness started happening and the update took two hours just to install even though it said "15 minutes remaining". Obviously, the update did not work. At the worst of times, clicking on anything results in the beachball. I have restarted my macbook multiple times and sometimes it becomes usable for a while before eventually lagging with literally everything I do.
Please help in any way you can!
Thanks in advance!!

Wow, thanks for replying so soon!

2008 Mac Pro 3,1 RAM burning up - running hot

Problem: 2008 Mac Pro Tower running hot.
Possible causes: Power Supply? Fan not working? Machine has 667 mhz RAM not 800 mhz.
PSU was chirping like a cricket a few weeks ago. I pulled it out, air cleaned it (and the entire Mac, vacuumed all the dust) and left PSU out for 12 hours to static discharge, etc. When I put the PSU back in, it was working and the chirping was gone.
Successfully used the MAC for a few days, no probs other than 2 DIMMS went bad. I went away for 2 weeks, tried to start-up the Mac yesterday and it wouldn't power on at all, no light. I unplugged it, tried different outlets, power cords, etc. Then I removed any changes that I had made previously (i.e. installed diff HD and 2 new RAM DIMMs to replace the ones that burned up) before going away. I removed PSU and let it sit while I cleaned the 2 DIMMs that had seemed to overheat before I went away. Put it all back together (PSU, old DIMMs which were cleaned and left HD #3 out) and it powered up. I then noticed that I was down from 32 GB RAM to 16 GB very quickly. The machine had also "shut down because of a problem" during that time then restarted and ran for a bit. I repaired the 16 GB RAM by cleaning it, brought it back up to 32 GB again and within minutes it was back to 24 GB. I pulled the RAM cards out and they were hot. The last 8 GB to go were likely the only DIMMs I haven't cleaned yet. I don't know how long that fix will last. Seems like we have a pattern of over heating.
Any ideas? Is it the 667 mhz RAM? The PSU? The fan? (How do you test a fan?)
Thank you for your time.

First the RAM must be made for your computer as determined by Apple:
https://discussions.apple.com/docs/DOC-6413
Thus you have an early 2008 Mac Pro if it is a Mac Pro tower and not a MacBook Pro notebook.
The RAM must be either preinstalled by Apple, or from a place that sells lifetime warranty early 2008 Mac Pro RAM.
Just because you got PC6400 DDR2 ECC 800 Mhz FB-DIMM with 256 bit wide memory architecture, as the specs call for,
does not mean the RAM is compatible. Only RAM stated to be for "early 2008 Mac Pro" is compatible with those towers.
http://www.macsales.com/ (OWC) http://www.datamem.com/ and http://www.crucial.com/ all sell RAM by stating the time of year and model name.
Do not buy ValueRAM. If after doing that it doesn't work, some directions for other interior repairs exist on http://www.ifixit.com/ and http://www.xlr8yourmac.com/
Check to make sure the circuit your machine is on is giving off the full amp called for by specs and that current is not split to other devices, and you have either a UPC or surge protector power cord that can handle that ampere. If there is any chance the machine was plugged in during a lightning storm, your power supply may be fried even with a surge protector or UPC being there. No surge protector is 100% lightning foolproof.

2010 Mac Pro fan gets really loud after 10.8.4 update

Hey all,
I've been having some issues with my fan since upgrading to 10.8.4, it's been incredibly loud compared to what it use to be. I typically run very graphic intensive programs and heavy video use but even simple tasks like browsing the apple site with nothing else running the fan slowly ramps up it a distracting volume. You can even hear it in the next room.
I've reset the ram, done a clean instal, blasted out any possible dust, it's in a well ventilated area, even run system hardware tests Nd everything passes I really don't know what else to try? I've searched lots on the Internet and I can't seem to find a solution nor do some others. Some say it will be a fix in a later update? Is this a known issue that needs to be fixed? I miss the snow leopard days :(
Everything was wonderful until 10.8.4...
Any advice or tips would be greatly appreciated I love my macs but can't work with really noisy machines.
Thanks y'all!

I know there aren't 'as many' but it is better now than it use to and you don't need $2000 Quadro 5000 or something, a $600 GTX 680 or somethjng from EVGA will do
Don't know what but MacRumors did a good job on one thread detailing possible GPU AMD FirePro possibilities. Yes it is huge change.
People have always said that about PCs. I have a few. Not for gaming but that is the only way if you want like a small percentage of users, to spend on GTX 690 x 3 for $$$ (big bucks just for gaming).
I can't recall a Mac Pro 5,1 2010 with 2.66GHz (sounds like a 2009) and 12-cores. 2,26 GHZ yes but that is just, does not make sense to give up MHz for more cores. The 12-core 3.34GHZ custom build, yes, but again that was never an Apple BTO choice either.
Apple has always disappointed geekheads you might say.
