What is normal fan speed & temperature? (2009 iMac)

I recently bought a 27" iMac used, and I noticed today that the fans seem to run fast even when just looking at articles without video, which I found odd.
Are the below stats normal? I've noticed the Optical Drive fan at around 3300rpm at times.

If these temps are in Celsius, they seem somewhat high to me.
The GPU and GPU diode seem unusually hot to me.
I have the same model IMac as you and purchased used in 2011, my initial temps weren't as high as yours, but I was still uncomfortable with how hot it was running.
I suspect a lot of dust dirt and lint may have built up inside of your iMac.
SInce you cannot break into the iMac to clean out the dust and dirt, I recommend the use of a vacuum cleaner with a hose and crevice tool attachment to suck, instead of blowing, the dirt out of your Mac.
DO NOT USE CANS OF COMPRESSED AIR!!!!!
You will only be pushing the dust, dirt and lint further into the iMac
Power down your iMac, disconnect the power and all your connected peripheral devices, lay your iMac screen down on a soft cloth of heavy toweling and using the vacuum's crevice tool(avoid using the vacuum's brush attachments as this may cause an electrical static discharge issue) and lightly (to avoid scratching your iMac's finish) vacuum out the vents underneath the display. Also, unscrew the RAM compartment cover and vacuum the dust out of the RAM area. Vacuum the long upper vent the is across the back of your iMac. Vacuum out the CD/DVD slot and SD slot. Vacuum out all of the various connection ports on the of your Mac including the vent hole and grille that is visible through the iMac's support stand. Once done, re-setup and reconnect everything and power up your iMac and see if the temps go down.
If no joy in getting the temps down, call an Apple Store or Apple Authorised seller/repair/service center and ask about if they do interior cleaning of IMacs and its cost and schedule an appointment to get your Mac clean and free of interior lint and dust.
If, after a good clean out, you are still uncomfortable with the normal operating temps, as I am, you can do one and/or two things.
The easiest and quickest solution is to run a small desktop fan from behind the iMac and let the fan blow air on the backside aluminum panel to cool down your iMac.
The next thing you can try and use (and you'll get a lot of subjective criticism from others here on what I am about to advise) is to download a software fan controller app, like SMC Fan Control, and manually set all of your iMac's fans RPMs to a speed which gets the temps to a more comfortable level without revving the fans too high, which can act as an internal vacuum, sucking in quicker, more dust, lint and dirt inside your newly cleaned out iMac.
I use a fan control app and do not set the RPMs for any of the fans any higher than 1500-1600 RPMs (the 2009 IMac fans usually default at 1100-1200 RPMs, so I only bring them up enough to keep the highest component temps below 60-65 degrees C.
Good Luck to you!

Xserve early 2009 normal fan speed?

Can anyone tell me what the normal operating speed for the Xserve early 2009 (xserve3,1) fans is?
I'm getting speeds between 5600 and 5888 RPM in a server room at 18 degrees Celsius.
David

Hi Camelot,
Thanks for your response.
Overall, the Xserve that I'm concerned about has a light workload. It's being used as a file and web server. Most of the time CPU load is around 1% - 5%. The room temperature is at 18 degrees celsius.
The System Board fans are all between 5600 and 6000 RPM.
The Power Supply fans are both at 6656 RPM.
These values remain pretty constant.
An AXD test didn't find anything wrong with the fans or sensors.
What concerns me is that Server Monitor reports the RPM values as the maximum value in its graph. See the attached screenshot.
This is not the case with our other Xserve, which is a G4.
I want to know if other users also report this behaviour or that perhaps something is wrong with the Xserve.

Fan speed & temperature

hello guys...
After 8 months before buying my geforce4ti4800se videogard, I began to notice some changes to fan speed & temperature while checking 3d turbo experience...
first of all, when I bough the card (winter season) I cant remember the fan speed but the card's internal temperature was about 39ºc while not playing and 45 ºc playing games... external temperature was around 15 - 20 ºc...
Now , card's temperature stays around 56ºC (without playing games) and jumps to 58 - 59ºc after playing games... Local temperature (32ºC) ...
I cant remember the fan speed at winter but now Im getting a blink message on the driver and the fan speed stays at 3300 rpm....
The increase of the temperature is related to a fan slowdown..? If YES, how can I fix the fan to get more speed? (Its not a source problem)....
Is 58ºC ok for the card or should I get worried about it ?
Help me please!! Thanks a lot,

Without full system specs in your sig line, it's very hard to help. Minimal information gets minimal help. Some people here won't even bother to answer w/o the info, and I can't say that I blame them, especially when the instructions are at the top of the forum.
To me, w/o any other info, it sounds like you have a case ventilation problem.

What's the normal fan speed?

Hello, my fans have always been around 2000 rpm with both tiger and leopord, so I am wondering what is the normal range for fan speed when the computer is not running anything heavy.

So, I'm not crunching much at the moment; yet I have 133 F and 3906 rpm. However, that doesn't signify. It was flat on a wood table. Now, laptop; Room fan now on. That fan is the main thing. I read a great overview, will post link if I can find it, that air is like fluid dynamics: a MBP flat on a table in an air conditioned room (no fanned air movement) will run hotter than an MBP with space under, with a room fan, moving warmer air. Yah, no, really true.
Get freeware iStat Control 1.1 (1.2 soon): (http://www.islayer.com/), which will display fans' speed and temps in the menu bar, andmore, and make popcorn too, with the lavalamp thingee.
Then I use Fan Control, 1.2, freeware, and set it up a tiny bit just to be cool: " ... Do you think your MacBook (Pro) is running to hot? Give Fan Control a try then. Some MacBook (Pro) are just to hot for daylong use. Fan Control adjusts the minimum fan speed depending on the current CPU temperature. For safety, it leaves the original automatic fan speed control intact ..." Leopard Ready, yah.
http://www.lobotomo.com/products/FanControl/index.html
Both are preference panes in System preferences, which is very elegant, imho. And yes I have Leopard still shrinkwrapped. I will take a stab at it soon. Goodbye, cruel world (nah).

Are my fan speed/temperature normal? Please answer quickly, warranty is expiring!

I have an MSI GF4 TI4200-8X.
I had some problems with my computer, when playing certaing games it freezes after a while, with reboot needed. I think I got down to my graphics card overheating. While using 3D turbo experience, I found out my fan speed was about 2700-2900 RPM (I think it is the minimum!!!) and my temperatures where around 52-55 idle. Today I noticed my fan slowed down, and it wasn't even showing fan activity, I tried pushing the fan a bit and it stopped completely. It has restarted again, with fan speed around 1700, after leaving the computer running for a while it got back to 2700 with slight variations to 2600 +-. The temperature went up to 58º!!! But I think it's "stable" now at 53º. What I'd like to know is if these values are normal for my graphics card. I couldn't find much information about this in this forum, one or two messages mencioned fan speeds around 3900-4000. As my board is still covered by warranty I'd like to know if I have reasons to send it back. So.......do I?

Quote
What does usually happen there when you have a graphics card under warranty, and it has a problem, you send it back right? And in the meanwhile? They give you a replacement until the other one comes back from repair (or even exchanged by a new one) ? I don't really know how these things work in these situations..
Like I said you will be without a card for a while. It could take weeks or posibly a month or more. It is not like a car. Contact the reseller to see if you still have a return possibilty with them, otherwise, you have to go to MSI for an RMA request.
An aftermarket cooler can be found at an online retailer or even at a Consumer Electronics SuperStore but I do not know what you have in your country. Thermaltake http://www.thermaltake.com/ has good products, perhaps you have a reseller in your area that sell their products.

IMac 27, i5/i7 - Fan speed / temperatures during gaming?

Hi all!
This is my first post in this forum. I have searched a lot in the internet, but I have not found any reliable information on this topic.
I currently have a MBP (see signature) and I am really happy with it. However, each time I am playing a game (just casually), the fans accelerate to 6200 rpm within a few minutes which is really annoying (= very loud, high frequency noise). Typical games are Sims3 as well as the Steam games TF2, Portal, and Torchlight. Furthermore, I am playing games like Black&White2, Bioshock or Chess using Parallels 5/Win XP.
I am now looking for an additional desktop computer - and I am loving the idea of buying an iMac i5. However, I would really hate to hear this loud fan noise again... (the alternative would be a Dell XPS 7100, but I really love OS X after 20+ years using Windows).
Thus, I am looking for reliable data (fans rpm, cpu/gpu temperature) during gaming (under steam os x, parallels, and boot camp). Also any experience on long-term reliability of iMacs used for gaming is appreciated.
Thank you very much in advance!
P.S.: Hope my english is not too bad, since I am not a native speaker...

It's a simple match - the more power your computer uses, the hotter it gets, and the faster and louder the fans. The graphics card and CPU are the most power-hungry parts, and are used at a high percentage during gaming.
That said, my current iMac is the i5 (27", 4850) and it doesn't spin up the fans at all playing Torchlight at full native resolution. It does start whirring a little playing Bioshock/Portal/HL2, but not so loudly - the fan speeds go from 1100 (normal, nearly silent) to 1450 or so.
Temperatures I've not followed - but they don't actually matter, just the noise that is made to keep them under control.
In Boot Camp, much the same - although I don't have a fan-speed monitor for Windows, again HL2 would just slightly speed up the fans.
But! I would suggest waiting a short while, it's 10 months since the iMac range was last refreshed so it could be just about time for them to be updated.
ps Your english is perfect, I would never have guessed you were not a native speaker.

Is this normal fans speeds for MacBook Pros? See videos of my MBP in action

I can't figure out the fans on my MacBook Pro. The lowest normal speed for the fans in 2,000 rpm. They will spin up at times for no apparent reason to 5,0000 or 6,200 with nothing taxing the CPU while it's also pretty cool, usually around the high 30's or low 40's celsius.
The other night I was converting a movie with Visual Hub, with the process taking 80% of the CPU and the temp reaching 75 c with the fans staying at 2,000 RPM until about half way through the eight minute conversion. This is a time I would have expected the fans to kick in much earlier than they did.
I have reset the SMC previously with no effect. Coming from a Polycarbonate MacBook this machine is much nosier, but also much cooler running.
Check out the videos I made showing iStat and Activity Monitor during these episodes. Thanks for any feedback. I'm coming to the end of my 14-day return period and wanted to verify if my MBP is operating like others.
VIDEOS HERE.
Thanks for any feedback.

Thanks everyone for your comments and suggests.
S.U. -- I ran the Apple Hardware Test when I received the computer and it found no problems.
Travis -- Thanks for the insight to what normal range is for the MBP.
I opened a case with Apple to get the ball rolling and get assigned a case number. The tech on the phone could not look at the videos but didn't think there was a problem from my descriptions. He did suggest I take it in for a look.
Online I made a reservation for the Genius at the Apple Store that night. While I was waiting I was curious how other MBP's handled some serious thrashing. Since it was late and nobody was in the store, I loaded iStat Pro on three of the MBP's and opened Terminal. In two windows I ran yes > /dev/null and let them run.
On all three machines the fan speeds never got higher than the lower 4K rpm range. They all settled in around 90C and stayed there. One MBP ran these processes for about 40 minutes and the highest fan speed I remember seeing was 35XX RPM, and again around 90C, but it would fluctuate up or down a few degrees.
When my appointment came up I showed Rex, my Genius rep (Cleveland, Legacy Village store), what I had done on their machines just to get some perspective on how other MBP's handled both cores running more than 90%.
My MacBook had been asleep for a few hours. When he woke it up the fans went immediately to 4200 rpm and stayed there. He hooked up a super-duper, special, double-secret HD via firewire and booted off that. The problem persisted.
He took it in back to crack it open. He was looking for any loose connections but found none. He could not find any errors but agreed that something was amiss with my MBP.
He was not sure if my computer, being a refurb, was different when it came to returns. We called Apple on my cell, got a rep, and he arranged for them to take back my Mac since I'm within my 14 days.
So props to Rex for his great customer service and a happy ending.

Help with Fan Speed/Temperature Monitoring - 875P Neo Series 2.0

Hi
My mobo manual doesn't explain the monitoring facilities available on this board and I would like confirmation of the following:
My P4 Northwood CPU Fan as supplied with P4 is connected to CFAN1 and provides monitoring of temperature and fan speed and also permits fan speed control.
My Northbridge Fan as supplied with mobo is connected to NBFAN1 and provides monitoring and control of fan speed. No temperature monitoring available.
My mobo provides monitoring of system temperature but doesn't say how this is measured and at what location.
There are two other 3-pin fan headers on the mobo; one is labelled SFAN1 with Gnd, +12V and the third pin NC and the other is labelled PFAN1 with Gnd, +12V and Sensor pins.
My new Antec 500W SmartPower 2.0 PSU has a monitoring cable that is wired with a black Gnd wire and a blue Sensor wire and, according to the Antec manual, is supposed to provide fan speed monitoring if connected to PFAN1 - I have tried this and get no information showing in either SpeedFan or Sandra. ???
My new Case fan, an Antec SmartCool, also has a monitoring cable but only has the third pin wired, presumably a sensor wire, and presumably could also be attached to PFAN1 instead of the PSU signal connector to provide fan speed monitoring. ??? Obviously I cannot connect both the PSU and Case Fan sensor cables to the mobo because the SFAN1 connection has no sensor pin connected; I presume this one is just a power supply to a fan as an alternative to using a supply line direct from the PSU.
Can anyone advise me on the correct use of the PFAN1 and SFAN1 connectors and what they are capable of.

- System temperature is measured at the Winbond W83627HF sensor chip located in front of your PCI slots.
- PFAN1 does indeed monitor PSU fan speed if the PSU has a fan speed reporting header. Not supported by some monitoring software (if Speedfan can't detect it, it doesn't support it. At least not until Alfredo's next revision).
- SFAN1 provides power only, no monitoring.
- Try a different monitoring software and see if it can detect the sensor monitoring your PFAN1. There are other monitoring software out there you can try, such as the CoreCenter that came with your motherboard, or Motherboard Monitor 5 or PCWizard (though you cannot adjust fan RPM through those programs).

Memory/Speed early 2009 IMac

I have an IMac (20 inch early 2009) With 2 GB 1067 MHz DDR3 memory and after updating to Yosemite 10.10.1 it has slowed down. I was wondering if increasing the memory would help speed things up?

I think upgrading RAM could help its performance. You can upgrade till 8GB(two 4GB DDR3 1066MHz SO-DIMM).

Time Machine backup to Drobo seems slow. What is normal write speed?

I just got a Drobo with Firewire 800. I'm using it exclusively for Time Machine backups. The write speed to the Drobo appears to be about 3 to 4 mb/s. Is that normal? Anyone getting the same or similar speed? I used to backup to a LaCie drive (which, of course, died) and it was way faster.

That's much too slow. Try the things in #D2 of the Time Machine - Troubleshooting *User Tip,* also at the top of this forum.
I don't understand with CCC is so fast comparing Time Machine initial backup. I hope incremental TM backup faster...
Some of the difference is that CCC is most likely doing a "block copy;" whatever's in each block on the internal is copied to the external; no checking, no indexing, etc. It assumes everything is in order.
Time Machine is making all the directory entries, hard links, etc., file by file, and indexing each file. Overall, it shouldn't take much longer than CCC (I use both), so one or more of the things in #D2 should greatly reduce the TM backup time.

Why is it that I have to install a third party software to control my fan speeds when my iMac gets hot. Should't the system manage this. My iMac is over heating because of this. Is there a way to let me iMac manage the fans?

I've read many posts talking about using a third party software to manage the fans in my iMac. Can the iMac not do this on its own?

You don't have to do anything. The fans will run when the temperature gets hot enough to trigger them.
My new 2012 iMac isn't like my older 2007 iMac in terms of fan noise. I knew when the 2007 fans were running, I could hear the sound of rushing air and under heavy load they were load. Because the new 2012 models are very different in construction I don't hear that typical sound. In fact, until I saw a teardown I wondered if it had fans. The fan sounds more like a hum and I just never associated it with being a fan. Yes, the top of the computer does get hot, I think part of Apple's design is to use the alumnium back as a heat sink.

What are Normal Disk Speeds

I think that my hard drive is very slow. That's how it seems. This is what hdparm shows:

Are these times slow?

Wait, there's more
But nothing LOOKS funny to me either here. But I tell you, opening a file in OpenOffice or sometimes just typing a URL into Firefox takes 10 times what I think it should. It was faster before, too. Not sure what/when it changed.

What's normal transfer speed?

Trying to transfer from iTunes to new 30G via recently installed USB 2.0 card (device mgr says USB is working). So far have transferred 117 songs in about 3 hours. Tried moving to old USB 1.1 and even slower. What's average real world transfer time for 117 songs (550MB)?

It takes 20 minutes to transfer seven entire movies onto mine, each about 500 MB.
I can see 2000 songs taking maybe an hour, but three hours for 117?
They might be encoded with the Apple Lossless codec, which then would make a 4-minute song about 100-200 MB...

Intel Imac fan speed? normal ?

Hi guys , im a new mac user and i was wondering i downloaded istat pro
and i noticed a low humming noise when running so i lookd at the fan speed and
the
cpu 1200
harddrive 1600
optical drive 800
im not sure if those are good temps but liek some times after using for a couple hours while just webbrowsing and listening to music i feel the heat coming from like the screen and i touch it and its pretty hot!
an i just use it for webbrowsing and music and downloading like the only third party software i own is utorrent and handbrake..
i posted my computer stats below
are Overview:
Model Name: iMac
Model Identifier: iMac9,1
Processor Name: Intel Core 2 Duo
Processor Speed: 3.06 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 6 MB
Memory: 4 GB
Bus Speed: 1.07 GHz
Boot ROM Version: IM91.008D.B08
SMC Version (system): 1.45f0
ATI Radeon HD 4850:
Chipset Model: ATI Radeon HD 4850
Type: Display
Bus: PCIe
PCIe Lane Width: x16
VRAM (Total): 512 MB

Those look like normal fan speeds for the latest Macs. But you can use software that allows you to create different speed sets for different circumstances.
I use smcFanControl. The first time you start the app it reads your Mac's default fan speeds and creates a default set. But you can create more sets with increased speeds. I live in Monterrey, Mexico with no air conditioning, just fans. It has been around 40°C everyday for weeks on end, and lately hotter. So I have a Hot set where all speeds are ramped up 200 rpms over the default speeds. And I have a Really Hot set where they are all ramped up 200 rpms more over Hot. If I see the temps edging up I usually choose the next set and increase the rpms and that usually brings the temps down to normal. If I see the temps drop down below normal I back off a set on the rpms.
I think Handbrake is probably a bit CPU intensive, so it probably sends your temps up above their normal range when you are just surfing the net.
BTW, rpms are not temps, those are fan speeds. Revolutions per minute.

Powermac G5: What are normal temperatures?

I recently started paying attention to the temp readouts using a temp monitor. Now im not sure what the normal temps are for my processors, but 180.00F seemed really high. I am running dual 2.7's.
Can anyone tell me what the normal range of temperatures are for a G5 with similar specs? Im not sure if i should be concearned or not..
G5 Power Mac
Dual 2.7g
4g Ram
6800 Ultra
2x 400gb HDD
Thanks so much for any assistance.

Hello all,
I'm using a G5 2,5GHz DP and I recognized also that the CPU temperature was quite high. Also I found the noise of the fans quite annoying. They were spinning up i.e. when opening FileMaker databases over a network or when I was starting an iChat video conference and so on.
Then I found out the following procedure to reduce the temperature of the CPUs and also the noise of the fans:
First download CHUD from the Apple Developer pages and install it.
http://developer.apple.com/tools/download/
After successful installation you'll find a preference pane called "Processor" in the "System Preferences". Open this Preference Panel and activate the option "Allow NAP".
Then please open the Preference Panel "Energy Saver" and there click onto "Options" at the top of the window. Then you'll see a preference for the CPU performance which you should set to "Minimal".
I know that this will cost performance, but if I do really need best CPU performance I can set it to "Maximum". All the time when I just use my G5 for normal office work, it is much more quiet than before. Of course this is not a solution for server or XGrid environments, but it is perfect for offices.
The average CPU temperature of the upper CPU (A) has been reduced from 75° C to around 60° C. The average temperature of the lower CPU (B) went down from around 65° C to 50° C.
Hope this helps.
