Fan / RPM questions...

I've noticed that my MacBook Pro's fans seem to be running louder and in a somewhat quacking fashion. I've downloaded Fan Control and iStat, and between the two they have shown the fans running at an average of 5800 to 6000 rpm. That explains the hum almost quacking noise.
What I am wondering is, is this normal? Should it be running that high and fast?
I do tend to run multiple programs at once. Mozilla, MSN, World of Warcratf, and various others at one or any given time. Would this contribute to the rpm and it's loudness?
Is there a particular way to fix the loudness? Or do I just have to deal with it?
My main questions are just is it normal to run this high, and any way to reduce loudness.
Thanks in advance.

There's a definite maybe in here somewhere. . . .
If you have a lot of applications that use more of the processor, then Yes the fans will come on and they should stay on until everything is cooler.
However, this sounds somewhat more persistent than the norm, so I would start to delve a little deeper. I note that you already have the iStat application installed which is showing the speeds. Can I ask, are these speeds occurring as soon as you start up (or wake from sleep)?
I would suggest looking at the Activity Monitor utility (Applications>Utilities) and seeing which processes are showing the highest levels of processor use. Clearly, if one process is running away, that can be stopped (then monitored for repeat offending).
On occasion I have found a widget might be misbehaving, and recently the Firefox beta too. There are other processes which may be awry, depending on what you have and what you use.
WoW seems a possible -- I have seen this mentioned in other threads. If it IS just that one, then it may be normal (although I wouldn't like it). If there is nothing other than that, a trip to your retailer might be on the cards.

Question about 970 fan RPM

I just got a 970 and so far I'm loving the performance, but I noticed something a little weird about how it controls the fans. My temps hover right around 60 when gaming, so I'm just at the threshold of where the fans kick in. When I look at the fan RPM graph in afterburner they are switching rapidly between 600 RPM and 0 RPM. I was wondering if this is harmful to the fans in any way, because from what I can see in afterburner the card is constantly turning the fans on and off. I'll post a pic below of what I'm talking about.

maybe overclock your card, let it reach a bit higher temperature, so the fans could remained spinning?

Harmful fan rpm?

Hi there!
I just downloaded a program called Temperature Gauge from app-store. The program tells me of how hot my computer are and how high the fan's rpm is. Right now i'm running Starcraft 2 and the fan rpm i almost maxed at 5900 rpm (the rpm bar is red and almost full). However the computers temperature is at 93 C.
My question is, does my macbook take harm from running it's fans this fast although the temperature doesn't seem to be too high?
Hope you understand the question and have a great day!

The fans are reacting to not just cpu temp though. They are also influenced by gpu chip temperature and other sensors on the logicboard. Often the gpu chip set can be generating a lot more heat then the cpu if you were doing something graphicly intensive like a game.
MBP's can get pretty toasty sometimes, but I've never had any heat related issues with mine (which is a late 2008 model bought in early 2009). It can be a bit of a surprise when you first ever hear the fans ramp up to max 6000 rpm though!

The fan RPM increases a lot whenever i plug in my battery

I recently bought a new battery for my laptop and whenever I plug it in, while my charger is plugged in, the fan RPM increases as if I am using 100% CPU and 100% RAM. Could this be caused by the new battery?
I have an hp dv7-3111ea and bought this battery http://www.ebay.co.uk/itm/140961851908 .
This question was solved.

Hi @CreaTivEuk ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv7-3111ea Notebook and issues with the newer battery. Here is a link to test and calibrate the battery.
Plug the power adapter directly into a functioning wall outlet. Do not plug it into a power strip, surge protector, or secondary power source as this could cause and issue.
The link you sent does show me the correct battery for your HP Notebook.
I recommend to restore the BIOS defaults with this document selecting the reloading the BIOS default settings

HT1305 how can i turn down the fan rpm that's between the optical drive and hdd in my power mac g5 dual 2.3?

how can i turn down the fan rpm that's between the optical drive and hdd in my power mac g5 dual 2.3?

Ok, I saw that error in your logic. A Dual G5 2.3 or even a Dual Core 2.3 does NOT use LCS at all. Its air cooled and if anything if the OP is experiencing this problems could be due to possible heatsink paste drying up. He might have to re-apply MX 7 or Arctic Silver.
The only G5's that use LCS are: G5 dual 2.5 from Late 2004, the G5 Dual 2.7 from Early 2005, and lastly the G5 Quad-Core from Late 2005-end of September 2006.
Hope this helps.

Still NO fan RPM after 13.12ccc?

hello i just want to know what happened to the fan rpm on my msi r9-290? it had fan rpm in CCC13.12 but anything above that i don't get it. even with the new full 14.4 drivers still no fan rpm?

Ok one more thing thats going on with the card now. IS after playing a game or video the card (msi R9-290 gaming) gets stuck on its full load settings at full power (977/1250 or 1007/125 at 1.248V) making the card hit about 56c when idle just on the desktop. i have to power off the pc to reset the gpu so it goes back down to 300/150 when idle on desktop. and to top it all off the fans don't go above 18% anymore??. only way to get them to go over 18% is to use MSI afterburner unclick auto on the fans and set it to 100%.
can someone let me know if theres a fix for this please. thank you

Huge CPU temperature, low fan rpm, is it normal?

Hello!
I'm a new mac user, I have a new macbook 2.0Ghz, 4GB Ram and a hdd 160Gb.
I compared the temperatures of my mac with other macs and my values are huge.
In normal CPU usage I get 60ºC, but when I turn on my virtual machine the CPU temp can go to 84ºC and the fan is only at 3265rpm!
For example, now I got CPU usage of 70% and it's at 80ºC and the fan is at 2456rpm, is it normal?
Above there is a list of CPU temp and respectively fan rpm
84ºC - 3265rpm
80ºC - 2427rpm
78ºC - 2004rpm
60ºC - 2000rpm
45ºC - 1998rpm
40ºC - 2001rpm

Hello All, I have a early 2008 Macbook 4.1, with a 2.1 Ghz, 4G ram, and a 7200 RPM HD, and I am also frequently between 60-85 deg C. (140 - 185 deg F.)
My fans runs between 1800 rpm up to 6200 at higher CPU temps.
Sometimes I wonder if running the Macbooks wifi, bluetooth, and an external 24" monitor, increases the interior temp?
I have had on occasion, doing some encoding with a slew of programs running, had the temp up to 96 deg C (205 deg F), and it still was running fine, mind you I was freaking out.
But when I checked on the Intel site for max CPU temp for my model processor T8300, it said that it was 105 deg C as the maximum. 105 deg C converts to which is 221 deg F.
I figure that they must have some kind of CPU shutdown/slowdown mechanism so if it gets too hot.
And if it doesn't, my 3 year AppleCare will have to deal with it.
I am more interested in the Hard Drive temp, since if that cooks, there goes my "restore plan" into action. But it generally stays around 90 - 100 deg F.
My buddy has an iMac, and it runs between 70-100 deg F. Go figure, it's cold as ice
Just thought I would share my 2 cents worth, IAN...

Sorry, BIOS is Rev 1.0, CPU fan RPM still wont show, on Promise SATA and I have no activity led??

Yes, everything is properly connected, CPU fan is on CFAN1 and the HDD is on the Promise and the front panel led connector is properly connected.
Anyone know what the heck is wrong?? maybe my board has LED on VIA and not Promise opposed to Promise having it and VIA not??
and why won't my bios display the damn CFAN1 RPM's??? I tried every connector also.
any help?
thank you

Ok, this is weird, the HDD led connector was connected as directed in the manual, black (ground) on pin 1 and red (+12) on pin 3, whats weird is that I flipped it upside down (red on pin 1 and black on pin 3) and now it works, that just weird but at least it works now. every other connector works when connected normally, funny that I have to flip the HDD led connector upside down haha.
Anyway, still can't figure out the CPU Fan RPM, why it displays 0 while the Fan is actually running?? I don't know why.
Have you heard of that problem??
Thanks again guys.

Macbook pro 13" june 2009 fan rpm remains at 2000 rpm when temp is 85c

Hi,
I've just bought a new macbook pro 13 inch and updated software vis software update.
I've noticed that the fan rpm went to 2700 rpm on every boot but
after a few minutes it goes down to 2000 no matter the temperature is
I'm using iStatPro to see the temp and fan
I've tried open youtube videos to raise the temperature to 71 but the fan remains the same at 2000
Please advise.
Thank you

Thank you for the info
I've just tried resetting the SMC but no luck.
since this is my first mac computer so I'm not sure if this is normal or not
after an investigation with different scenarios of work load I found that
room temp : 27c
cold boot : cpu 45c
: fan 2000 / 2700 rpm
warm boot : cpu 58c
: fan 2000 / 2700 rpm
running parallels
with windows 7
and visual studio : cpu 75c
: fan 2000 rpm
The fan did kick in to 3500 rpm once the temp is 85c
I'm not sure if this is normal or not since my Dell M1330 xps
which running vista and visual studio shows only
cpu: 58c
fan: 3000rpm
Thank you
I'm not thinking about using SMC fan control to set the default to 3000 rpm
and use it only when I work on Windows but not sure if the program will damage
my new baby or not
Thank you

CPU temps rise 10c and fan RPM goes up by 1K on resume from suspend

Unfortunately, it will be hard to determine what update prompted this issue as I didn't notice the problem right away. However, recently my Thinkpad x220 began experiencing a 10 C increase (as reported by sensors) and a 1k increase in fan RPM on resume from suspend. I started to suspect the suspend being the culprit, so I ran sensors, it came back with 44C temp on my cores, and a 1900 fan RPM. I suspend the system and then bring it back. If I run sensors again immediately upon resume the core temps have risen to 55C and my fan RPM is around 3K. A reboot of the system corrects this issue and brings the temp and RPM back to the pre-suspend numbers.
System is up to date and uses Kernel 3.6.1 and testing repo. I am getting ready to back down from testing to see if the problem goes away, but, has anyone notices similar behavior?
Update: I have narrowed the problem to kernel 3.6.1. Temp and fan are working normally after moving back to 3.5.6.

This should probably go in the Testing section.

GTX660 low fan rpm

Msi r9-290 gaming (fan RPM )

Hello can anyone help please . my r9-290 gaming dose NOT show the fan RPM any more in GPUZ or in MSI afterburner. it use to in 13.12 but now nothing shows on 14.1 (fan rpm = 0 ) fans are on and running on desktop they are at 18% and go to about 40% in game.
plus in MSI afterburner the gpu ram speed keeps going up and down like a yoyo.
here is a screen shot of what i mean.

will i need a BIOs update?
just if its needed bios link https://www.dropbox.com/s/n6pffrb5y1zzotf/Hawaii.rom

Hi hpipiw
I think the fans are actually fine, its definitely looking like a software issue, I didn't see this problem before installing afterburner, and setting a higher min fan speed seems to have cured the issue for now.
I can imagine that a fan thats seizing up might just stop at lower speeds, but I would think it would struggle to start up when touched.
Keeping an eye on it for now, will of course rma if I notice anything bad happening.
Cheers for the comment.

Platinum sli 7125 - temp / fan rpm sensor playing up

Recently installed a new nexus fan and a psu into my system ( see sig) and finding the fan and temp sensor chip is giving me odd readings...
It was fine previously and reported the consistent values through corecenter, speedfan and everest
Now I am sometimes getting temps of -99 for cpu, fan rpms dropping to 500pm on cpu even though the speed is not changing.
All readings from corecenter, speedfan and everest tally
It is solved by a quick reboot so a little confused as to why it is happening?
I do have the latest bios 3A, which was put on 6 months ago, no changes recently apart from the new more powerful psu and a new rear case fan (replacing my older antec one) which is running off s_fan1 3 pin point rather than the antec one which ran off the psu directly
I may try swapping the nexus to run off the psu directly...
thoughts welcomed
thanks

odd
all is back to normal it seems
I can only conclude that there is some spiking or irregular current flow via the 3 pin wires off the nexus...
it is now fine off the psu - good thing the nexus is only 22db at 12v ! as I could not bear to go back to the antec fan at 12v

Fan RPM's read 0 in BIOS no matter where I plug the CPU fan, but it registers in Core Center???

Hey,
I used to have BIOS Rev 1.0, updated to 1.2 thinking it would fix the problem about the Fan RPM's not registering, meaning they show 0 in the BIOS, but it didn't fix it, but it registers normally in Core Center in Windows XP Pro.
What the heck is the problem?? are any other poeple getting this problem?, everything is correctly connected and operates correctly.
Specs are in my signature.
Thank you,
Frank

I have the same problem. Don't worry too much about it. Most BIOS' won't recognize a CPU fan below a certain threshold, and the Thermaltake Silent Boost's stock fan probably fits into that category.

Fans rpm going all or nothing

I have a weird problem in my macbook pro 17"
The fans start out at 2000 rpm, which is as it should be,
Then after some time they go 6000 rpm in one go.
Then they lower again to 2000.
it seems as if there is no inbetween for them, all temps look ok, nothing is hot, no processes going nuts.
This also happens when I am at the Boot selection and OSX is not even loaded.
Things I did:
Install iStat pro to check the rpm and temps, all temps look okay
Checked for out of controll processes on all users, nothing wrong
Checked if it happens on all users > thats a yes
Checked if I can manually set fans rpm at 3500 > thats a yes! (so technically it can do it)
Reset the SMC, no difference
Ran a log over a long period of time of temperatures, no relation found and no exessive temps
One thing I do notice is that I see the battery usage go down a lot when the fans ramp up, this leads me to believe that something does happen and the mac reacts to that.
I just do not see anything to make the same conclusion as the mac
I am at a loss here, The mac seems to read all temperatures fine, it can technically controll the fans to all speeds but it doesn't do that in use.
It starts at 2000 and then all of the sudden it will make the fans go to 6000.
Then drop to 2000 to go a little later again to 6000.
Does anyone have any tip for me?

Found in the service manual that the TsoP sensor is the one on the Topcase.
a shame that istat pro does not show that sensor, does anyone know how I can see what that sensor is doing?
And does anyone know where it is mounted?
I cannot afford a completely new TopCase, so I am hoping to find the cheapest way for me to get this fixed. Hope I can find someone that has a topcase lying around or something smiles
