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.

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.

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.

Macbook Pro Fans Running At High Speed

My MBP 17" CoreDuo 2.16ghz came back from having the Logic Board replaced at the weekend. All is well except that now the fans run at high speed all the time.
I have installed SMCFanControl, and the current readings are 45 / 113 degrees and the fans are running at 5500 rpm. I took the machine back to the Apple store but when I was there the fans didn't go above 3000rpm (typical huh?). It's nice that the case is now a lot cooler than it used to be but the fans seem very loud to me.
The question is, is this normal? I am not running anything very heavy duty at the moment. Any ideas?
Thanks
Matt

I tend to agree with Ned on SMC fan control (that it arguably causes more problems than it solves).
I had a similar problem with mine recently having the fans run constantly and at full speed. My temperatures never approached yours, but it would fail to go to sleep etc.
I would start with the advice Ned gave you. This is the same path Apple Care led me down in trying to resolve the issue.
Ultimately though I had to do an archival install of the operating system. It is non-destructive so it wasn't a big deal. I just had to slowly re-install patches and observe behavior. Oddly I was able to patch back up to 10.4.9 without the issue re-occuring so the root cause is still a mystery to me.
edit
Patch gone bad maybe? I tried re-applying the 10.4.9 combo before attempting the archival install route with no success. I know that has been suggested many times. Apparenty it solves many issues, but it failed to solve mine.

Mac Pro Fans Kick into high

I have a Mac Pro with 2 extra HD'S in it. I leave the machine running all the time. After leaving the machine on (without restarting) for like 2 months, I have the fans Kick into high even though CPU load is low. They are very loud and they wont turn off. The only way I have gotten them to turn off is by turning off the computer. Has anyone else had a similar issue?
Ian

Turn off? hard or soft? ie, does it do a normal shutdown? if not the directory could be damaged.
Apple Hardware Test would be step #1.
Dust build-up or high ambient temperatures or not getting enough ventilation. You could use smcFanControl shareware app to force fans to higher rpm than 500-600 minimum rpm.
SMC Reset would be another.

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?

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.

Macbook Pro fan running at high speed but is not experiencing heavy usage

My computer is 3 years old and I've had no problems.
A few days ago the fan started whirring incessantly after the computer had been on for only 10 minutes or so, even when experiencing minimal usage.
This could be just a coincidence but the issue started about the same time I installed the latest security update, I'm on Yosemite.
Can anyone help?

The first thing to try is a SMC reset.https://support.apple.com/en-us/HT201295 Also check for run away apps. https://support.apple.com/en-us/HT203184 You could also make sure the back vent is not getting clogged.

MacBook Pro Fan running fast after Mavericks update

Hello All! I have a 2009 MacBook Pro 13 inch and I have noticed that after I updated to Mavericks my fan has been running really fast and my computer getting warmer than normal. It's always on a table so there is nothing blocking the port in the rear. Any ideas on how to fix this?

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.

Macbook pro fans running at 6200 rpm,running slowly and 35deg C?

About i week ago i was noticing significant slowdown in the operation of my mac. Yesterday the slowdowns were so much so as to render it useless.(30+seconds to realize that i had scrolled). I had just downloaded SOPHOS...it found nothing. so i assumed installing it had done something. i proceeded with a clean instal. After a few trys i was able to reinstall and boot up. The computer is functioning but not at the level of a wiped mac. there is still lag as i write this sentence, and at almost every action i see the pinwheel. I did a reset of the SMC and there are no hogs of CPU in the Activity Monitor(All programs). I downloaded a wiget to allow me to see temperature and fanspeed. the highest temperature is 35 degrees C and that is of the CPU, yet my fans are still posting speeds of 6204 rpm.
To make matters worse i'm overseas and cant seem to find information on a genius bar near me.(Toulouse France)
I feel like ive tried everything.
-Highfan speeds
-Laggy functioning (akin to a 5 year old PC).

I find it incredibly coincidental this happened the day steve jobs died....
Thanks for any help or advice you can offer.

Backup your files before doing anything. May be a dying hard drive, would account for slowness. Software update fully.
Perform a hardware test
https://support.apple.com/kb/ht1509
that should tell you if it's a bad sensor or something
And yes, perform another SMC reset because your symptoms are typical

Early 2008 MacBookPro keyboard backlight off and fans run at high speed

Hi!
I wrote from Turkey.
My Early 2008 MacBookPro 2.40 ghz 4 gb Ram OSX Mavericks machine's keyboard backlight off and fans run at high speed; it seems an exact smc resetting problem.
So i tried the 2 ways of SMC restting procedure; both battery you can move and not, but nothings changed on the situation..
On the way for removable battery; nothing changed but on the way for umremovable battery way; keyboard backlight flashes and gone, but fans are at high speed not changed. So nothing changed.
What can i do right now? i'll wait for your advices
Thanks

Your Mac may need a new PRAM battery. Once it is over 4 years old, that often is needed.
