Noisy fans on all the time

I have come over from the dark side today (PC to Mac switcher). I got a second hand Mac Pro 2.66 quad with four HDD and 4GB ram and i seem to have very noisy fans. I did find this article
http://www.amug.org/amug-web/html/amug/reviews/articles/intel/fan/
which mentions that extra drives cause more noise due to extra heat and less airflow but this is just silly, they sound like they are on full ALL the time.
I have alread tried resetting the smc_rst button on the logic board but that did nothing. I also tried restarting the machine with command, option, p, and r down before the grey screen on startup and that did nothing.
Is this normal. is it just down to lots of HDDs/RAM or should i be worried?

Mac Pro most likely for "MP" shorthand.
Considering how the drives are placed, can't see that they block air, though they may not get direct ventilation.
FBDIMM memory needs to be kept cool and the top memory Riser and higher density DIMMs do tend to be as much as 10C higher (with 2GB DIMMs running the hotest).
I wonder if you got it with a system already installed? or did a full 'wipe' of the system drive and started fresh. There is a little program most people now use smcFanControl which can force the fans to run at a minimum rpm (though not the PSU fan, either software defect, or the logicboard won't allow forcing it if the sensor doesn't register a higher temp).
SFC would put a little menu item on the menu bar and to acces the program preferences. There would also be a log-in] in user accounts, and a startupitems in the top level Library/Startupitems usually.
Also, look on the Dock for items that can be controlled from there to "open at login" or disabled without having to open any control panels.
If it was me, and I bought a used system, other than direct from Apple Store (Specials, great deals on refurd equip.) I would start over with installing the system.

T61 fan runs all the time on AC, does not when on battery

Hello,
with the lastest BIOS (and those before) my T61's (8889) fan runs all the time when it is AC powered. (After initial start it begins with 0, then ~2500 rpm, then ~3100 rpm and then stays there even if idle).
When on battery under the same circumstances, it doesn't go above ~2500rpm (which is far less noisy then the ~3100rpm level) and often it even stops.
As far as the BIOS settings allow, it is trimmed to max. power saving also when AC powered but still it's getting on my nerves.
Can Lenovo please look into this and make it as quiet as it is on battery also when on AC?
P.S. I cannot see that the temperature levels as reported through ACPI are any higher on AC then on battery, so I don't understand why the fan has to run all the time that loud when on AC.
Thanks,
Daniel

Hi Daniel,
There are two options for you to consider:
1) Better CPU speed management:
- Install a utility called "RMClock" to better manage the CPU (it's a free utility that throttles the CPU to run at different speeds depending on the needs - the CPU speeds increase automatically to full power when required).
- By regulating the CPU speed, the fan will not need to work that often to expell hot air, because the CPU generates much less heat.
- you will find a quick "how-to" for using RMClock --> HERE
2) BIOS thermal management
- You can change the BIOS settings for the "thermal management" (enter BIOS, choose "Config", then "Thermal Management" ) . Change the fan control from "performance" to "battery optimized" under the "plugged-in" option. This will reduce the frequency with which the fan runs, but beware that if your system is plugged in and you're not using any CPU management - meaning that your CPU is running at full speed, then the system will heat up more than you'll be comfortable with!!
I would therefore suggest that you use a CPU throttling management utility (like RMClock mentioned above) together with the thermal management option in your BIOS. This will reduce the frequency with which the fan starts and operates but still keeping the system cool.
A completely different approach is to install and use "Thinkpad Fan Control" -- read this thread ... Be aware that the utility takes a lot of tweaking to get the settings right, but also be aware that you can damage your system if you do not make the right settings!!!
Hope this helps!

Fan runs all the time after upgrade to 10.4

Upgraded to 10.4 about a week ago and now the fan runs all the time. I lowered the processor to reduced performance because the fan noise was very loud. Doing this lowered the fan speed but did not stop it. Memory usage is not a problem, shows 75% free.
Before 10.4 was using 10.3 fan ran at times but never all the time.
Any ideas.

Tom, have you down loaded an app like "X Resource Graph", I think I got it at VersionTracker, which will tell you what fan is running at high enoug rpm's to generate noise. Plus it will give you cpu usage and temps plus hard drive temps. If its the cpu fan and the cpu is really working, go to the Activity Monitor in the utilities file and see what app is causing the problem. I don't know what to do if it's the hard drive or system fan. My system fan rarely goes over 1800 rpm, my hard drive stays between 2000 and 2200 but my cpu fan will accelerate when its under pressure to to over 3000 rpm. I just start hearing the cpu fan when it gets to 2400 rpm.

Brand new iMac 3.4GHz fan runs all the time - how do I stop it?

Hi, just opened my shiny new imac but the fan runs all the time and very loud! Has anyone any ideas how to fix this or should I return the imac to apple?
I've also noticed that none of my external drive icon show up on the desktop - nor does the imac hardrive icon appear - any ideas?
Thank you in anticipaction.

Try an SMC reset, you may need to do it at least 2x.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Laptop fan runs all the time, broker runtime cpu usage after Windows 10 final upgrade

ENVY 17t-J100 Leap Motion, 16 GB RAM, i7, SSD primary, HDD secondary drives. Avast antivirus free. Windows Firewall. The laptop had Windows 8.1 and everything was great. I did the Windows 10 Home free upgrade on Day 1. Everything seemed fine. Fingerprinter reader and everything works. Great. But then I noticed that the fan was always running and the left side of the metal casing gets hot. In task manager heat map sorted by CPU usage, Broker Runtime is at the top. Not much ram, about 10 MB. But the CPU usage is always 20% and higher. Doesn't seem like much. But it makes the fan run all the time and the laptop heats up with it running all the time. Anyone else seen this? General internet searching shows this has been an issue with Broker Runtime since Windows 8 and not unique to any brand of computer. But it wasn't like this when I was using WIndows 8.1 One forum said it was the P2P Windows update feature and my laptop was sharing updates. So I disabled that and rebooted. No change. Now I see some people saying it is the Live Tiles features in the Start Menu. But I had live tiles with the WIndows 8 menu and no issues. The only way to disable Live Tiles globally is to edit the registry, and I shouldn't have to do that for this. And I like Live Tiles. So not sure that really is the issue either.

MBP Fans on all the time

Can anyone help with this.
My MBP 15" fans run all the time they dont ever stop, I taken this to an apple repair centre and the first time they replaced the top (keyboard) casing, that didnt work. I returned it again and they replaced the logic board and this hasnt worked either, Im sat here typing with the fans going mental (as am I). If I take this back again what will they choose to replace this time. If there is an apple guru out there please help.
By the way the only way I can get the laptop fans to stop is to pick it up off my lap and hold it vertically straight and the fans go off instantly. ***. Also whenever the fan problem occurs the keyboard light stops working. Ive spent £50 so far on travel to keep taking and collecting my MBP.
How many parts can they replace before I end up with a new one.
Regards Peter.

Hi Allen, thanks for the support. i did change to All Processes and there was nothing heavy going on, the only app I had running was chrome with this forum on.
Tomorrow Im going to contact the Apple Repair centre that has been doing the work so far. I guess Im just going to have to give them as much info as pos, pretty much what they have been told so far. Thing is you give your much loved macs to these expert and expect them to know what to repair but that doesn't seem to be the case with this. I deal with macs for a living but just not internally so its very frustrating. There are plenty of people out there with a similar issue out but the solutions people use seem to differ quite a lot, none of which have worked for me.
GET THIS
One strange way I can stop the fan is if the screen is kind of at its normal angle as Im using it on my lap, if I adjust the angle of the screen towards me about and inch the fan stops (LOL). What the **** is that all about. Only problem is its then very hard to use my laptop.
Cheers Peter.

Fan running all the time - 2011 21.5 inch i5 iMac

I purchased a new 2011 21.5-inch: 2.7GHz i5 on Friday just gone (2 days ago). All was going well with the new toy until this morning (Sunday).
Suddenly the CPU fan was running all the time and at full speed when the computer was not under any real load - very noisy.
I have reset the PRAM and SMC several times now. Within 30 seconds of each reboot the CPU fan reaches 4000 rpm and stays there.
When I run a hardware test I get the following error - Error 4SNS/1/C0000008:TS2p--124. This error is detected under both the quick and extended tests.
I do have to say that I am disappointed that 2 days out of the box it looks like I am return the iMac to the Authorised Reseller.
Can anyone confirm my understanding that:
a) the CPU fan running loud and hard (4000 rpm) when not under load is NOT normal
b) the Error code above relates to the logic board
c) next step is take it back to Apple or the authorized reseller from where it was purchased.
Cheers
Shaun

4SNS/1/C0000008:TS2P--124
When U install the SSD under the optical drive(OD), the air from the OD fan that was supposed to swing under the OD to exit on the uppper vent has no where to go and hence swings across and exits mostly through the vent on the other side near the camera whereon lies a Skin sensor, which blows away/damages tricking the iMac to believe that the CPU is hot and the CPU fan starts to run at full speed of 4000rpm and the Apple hardware shows error 4SNS/1/C0000008:TS2P--124.
This skin sensor will then need to be replaced.
The CPU Fan cannot be controlled by any software.
The only options available are:
1.Change the primary HDD with a SSD.This will result in the HDD fan running at a higher speed as the SSD does not have any moving parts.The HDD fan sensor gets to believe that the HDD is hot since it does not get inputs from the SSD.Once you change to SSD you can use software to control the HDD or the Optical fans.
2.Change the Optical Disk drive with a "SSD in a Optical Drive(OD) Caddy".This will result in the optical drive fan running at a higher speed as the SSD does not have any moving parts.The OD fan sensor gets to believe that the OD is hot since it does not get inputs from the SSD.Once you change to SSD you can use software to control the HDD or the Optical fans.
Do not use the OWC or other dual drive kit that advice U to put a next SSD under the OD, unless ur iMac is under warranty or u have plenty of technical skills & luck.

Mega PC 865 Pro - should the fan run all the time?

Samsung SpinPoint 250GB SATA II Hard Drive SP2004C
1GB Kingston Hyperx 512 DDR400 PC3200 CL3
Intel Pentium 4 630 3 Ghz Socket 775 800Mhz 2mb
LG GSA4163B 16X DVD Dual Layer R/RW/RAM
TV@anywhere-Master TV and FM Radio card
I'm sure I read that the CPU fan should not be runniing all the time? The fan runs constantly even when I'm not working at my PC. Is that normal? The box does not feel hot at all and I'm not running the TV card.
It's not that it's noisy but I had hoped it would be silent, like my Pentium M laptop. The fan on that only starts up when the computer is working hard, and then very rarely.
Thanks for a great forum. Imagine relying on MSI!

i don't know about the 865PRO, as i've never used one, or seen one in action
but on the other Megas, the fan usually rotates at a slower speed, until the temp increases under CPU load, then it speeds up to compensate
P4 Prescotts are hot CPUs anyway, and if they aren't installed correctly, they'll run hotter. try removing the heatsink, cleaning off all the old thermal pad, and using a good thermal compound such as Arctic Silver 5. apply a thin layer to the CPU die surface, and then refit the heatsink. make sure no stray cables are blocking airflow to the CPU heatsink fan.

Fan on all the time for about 1 week

Hi
I'm the still happy owner of a almost 3 years old powerbook G4 12". I have been troublefree so far when sudenly things started to go worng last week
1) I had the "privilege" to experience an hard drive "crash" (http://docs.info.apple.com/article.html?artnum=302411) related to disk utility. It took me 1 day to recover the data, then reformat the drive and reinstall 10.4, and apply update software all the way to 10.4.7 and other seurity update (Whoaaa that was long)
2) NOW: Since then my fan is on all the time. As soon as I start the laptop it's on and it goes off only if I put the laptop to sleep (or shutdow of course).
I did check sensor temperatures and everything is within range (even on the low side)
Battery 31degC
Graphic Processor Die 51degC
Hard Drive Bottom Side 40degC
Processor Top Side 43degC
Smart Disk Fujistsu 44degC
I have noticed a "2FAN/7/4: Fan for main enclosure" error using Apple Hardware Tool... Does that mean that my main circuit board is not working or that the fan controller is burned !!!
Anyway it's really annoying and I have seen that I'm not the only one suffering "the Fan Always On" syndrome....
http://discussions.apple.com/thread.jspa?messageID=1788983&#1788983
Any help from users or moderator? Is it temporary or do I have to bring the laptop to an apple repair centrer. The laptop is already 3 years old and I dont not want ot spend to much money on it. I'dd rather get a new one if the repair cost is too high.
Any help will be apreciated...
JB

Well if you had bought AppleCare, it normally would be free. Though if the machine is older than three years, or out of AppleCare, it may be more expensive. I've found these two places often charge less than AppleCare to fix out of warranty Powerbooks:

Pink HP mini 110 fan runs all the time...

Dear HP and community,
Does anyone know if it is normal for the fan in my HP mini to run all of the time? I love my pink little HP mini but the fan running all of the time is rather annoying. I got my HP mini at Best Buy and now they no longer have the HP mini in pink at Best Buy... If this is a mechanical problem, would I have to exchange my computer at Best Buy or would HP be able to help me so that I could exchange it for another pink one? I guess I'm getting ahead of myself! I hope it is an easy fix but am afraid since I've only had my mini for a few weeks....
Thoughts?
Erin

You probably should repost this in the notebook hardware forum where you will find other Mini users to compare notes. I have heard that the fan on the Mini comes on frequently, but not as you described (all the time). On the netbook front, I am still using the Asus 1000H, which is whisper quiet BTW.
If your 110 is determined to be faulty, HP will probably choose to repair it if it is still under warranty.

Noisy fans on all the time
