IMac (early 2009), 3.06 GHz, ATI 4850 - fan speed and temperature questions

Well, so I downloaded and installed Temperature Monitor and iMac Fan Control - mainly for observational purposes and not for toying around with the fan speeds and I've got some questions. Mind you, I haven't tampered at all with the fan speed settings, just installed Fan Control. Here are my readings (while browsing the internet with Safari and doing a chat via iChat):
Fan Speeds:
CPU fan (desired) 1300 RPM / (current) 1530 RPM
HD fan (desired) 2100 RPM / (current) 2099 RPM
DVD fan (desired) 1300 / 1298 RPM
Temperatures:
CPU Heatsink: 92°F
Internal HD: 108°F
Internal DVD: 95°F
GPU Heatsink: 107°F
Are these, under the circumstances, normal readings?
Thanks in advance for your replies.

Your welcome and no problem. I would say only the Apple engineers can tell you why the fans are set to those speeds however my best guess is the obvious they found those speeds the closest to keeping the temps at an optimum operating temperature. I found when I'm doing graphics intensive work my machine heats up but quickly cools down when I'm done.

Fan Speeds and Temperatures 24" iMac 2.8GHz

What are the default fan speeds for a 24" iMac 2.8 GHz?
Also, what are the 'normal' temperatures for this computer?

The default iMac profile is the best for general use. For calibration get a Spyder 3 Pro: http://spyder.datacolor.com/product-mc-s3pro.php

IMAC (early 2009) upgrade

I have a IMAC early 2009 2.4 GHz Intel Core 2 Duo. Can I add more memory so I can upgrade to OS X Mavericks.

Yosemite; back up your data, click here, and read the entire page. Mac OS X 10.7 and newer don't support PowerPC software such as Microsoft Office 2004; some other installed software may also be incompatible.

Kernel panic - iMac Early 2009 - OS 10.9.5

My iMac Early 2009 computer has been shutting down in different ways during different programs, usually graphics oriented. Usually it freezes the display or some part of the display, becomes very very slow and then maybe I can wait and save work before restarting, maybe not--it's just frozen. I was watching a video in Chrome just now and it completely shut down and restarted. This is the first time this has happened--complete shut down. I wonder if anyone can interpret the shut down log.
Specs are as follows:
iMac "Core 2 Duo" 3.06 24-Inch Aluminum (Early 2009) (E8435)
6 MB shared level 2 cache
1066 MHz system bus
8GB of RAM (1066 MHz DDR3 SDRAM)
1 TB (7200 RPM)
NVIDIA GeForce GT 130 graphics - 512 MB GDDR3
Log of the shut down follows. Thank you very much in advance if anyone has any idea what is wrong.

Thanks Mike. I have no third party peripherals, but I did install ram, so I'll take that out. I'm unable to install the Apple Hardware Test (holding D down doesn't work for me and I don't have the install disks that came with the computer anymore.) I think it is a hardware problem though, due to it happening during lots of different programs running etc. I'm guessing it is GPU related as well, because it says

From research I've done online, I gather replacing the video card will be half as expensive as buying a new computer, so I'm in a jam there. The iMac screen display is also quite old -- it has a yellowish color now and often on the desktop you can "see through" windows "on top": you can see the outlines of windows below.

24" iMac early 2009 - how to duplicate screen (mini DP to HDMI)?

Hello
I want to play movies on my TV which are located on this harddrive.
I have a PS3 so when i have software streaming that movies (uPnP style) to my PS3 it works. But then again, considering I like nature and all, I have to use 3 devices for getting that image through.
It would be far easier to just connect the mac to my TV using HDMI.
I know this is possible with a mini DP to HDMI cable. But does this iMac (early 2009) support audio streaming? I've read numerous of forums and they all have different answers. I know this forum is the right one to ask.
But if it doesn't support audio, then i'll need a devide which combines the mini DP and audio jack into a a hdmi output. This isn't such a problem I think except ...
If this audio jack is plugged in my iMac, won't I'll always loose the sound of my iMac (but I'll have that on my TV)? This bother me because I don't want to insert the audio jack every time I want to play a movie on my TV. But when the HDMI side is not connected to my TV, will my Imac still loose its audio?
It seems complex, but I just need a solution for watching those movies easily on my telly without having to switch cables all the time (and not use the PS3 which consumes power like a mad machine).
I'd like to know your input on this.
Thanks in advanced

The mini-DisplayPort does not carry audio. You can solve that issue with a device such as this one available in the USA. I do not know where you would find one in Europe.
However, as long as something is plugged into the Mac's audio port, that is normally where the audio goes. So if your TV is plugged into the audio port and the TV is off, your Mac will be silent.

That machine will support 8GB RAM, please look over

Adobe CS6.0 out of memory error on iMac (early 2009)

Hi:
Adobe CS6.0 Photoshop is returning "Out of Memory (RAM)" errors and is unusable on a lab of iMacs.
The system exceeds Adobe minimum specs (1GB ram).
Our school has a lab of computers with both Adobe CS5.5 and Adobe CS6.0 Master Collection installed on a lab of iMacs (early 2009).
The computers all have 4GB of memory and come with an NVidia GeForce 9400M 256MB video card.
I notice that this video card shares ram with the main system.
CS5.5 runs perfectly well but CS6.0 is not co-operating.
We have updated Photoshop to version 13.04 and have run Apple's Software Update (latest version).
I have looked online and this is a known problem with computers that have Adobe CS5 & 6 installed with Mac OS10.7.x but only on certain video cards.
There are people out there with 32 GB ram having the same problem.
I'm guessing the answer may be to update the video card drivers somehow.
Your input is greatly appreciated.
Regards
ODrew

Hi ODrew,
I'm shocked you can operate OK with only 4GB of RAM, that certainly wasn't enough for my 2007 iMac to not continually slow down!?
CS6 Sys requiremnts...
Mac OS
Multicore Intel processor with 64-bit support
Mac OS X v10.6.8, v10.7, or v10.8**
4GB of RAM (8GB recommended)
4GB of available hard-disk space for installation; additional free space required during installation (cannot install on a volume that uses a case-sensitive file system or on removable flash storage devices)
Additional disk space required for preview files and other working files (10GB recommended)

My microphone doesn't work after installing lion on iMac early 2009

Hello,
I've just installed LION and everthing seems to be OK except the microphone, it doesn't work on skype, imovie.
I have an Imac early 2009.
Will this bug be fixed in the next 10.7.1?
Please if you can help me,
Thanks

If it suggests that you install iPhoto again, install iPhoto again. In your Macs Box that it came in there should be 2 Discs, one is an Applications CD (You need this one) And another is the Mac OS X.
Insert your Applications CD and hold C while the computer is starting up, then you will be walked through the installation of Applications.

First is it possible to connect my imac eaRLY 2009 as display for my macbook white 2010?

first is it possible to connect my imac eaRLY 2009 as display for my macbook white 2010? If so what exact cables on the market do i need to purchase to make this work? Please help me out. I cannot afford to buy a new mac so temporarily this is my only solution.
Thanks to all my Mac buddies for your assistance

The Early2009 20" or 24" iMac don't have any video-in capabilities.
Depending on your needs, you can investigate or tryout AirDisplay or ScreenRecycler which enable use of a Mac from another Mac or Windows PC through network/wireless connections.

IMac (early 2009) not connecting to wifi

Excuse my typing I'm on my iPad so there may be errors!
Day before yesterday my router dropped the signal. By morning it was back on all all devices (iPad, iPod, Xbox, my dads pc etc) were working fine, but now my iMac will to connect to the wifi. It's driving me Barmy! I've called the provider, there is no problem their end any more, and they know nothing about macs so couldn't help.
I have tried everything. I've renewed my dchp lease, I've restarted and reset the router, restarted my mac, unplugged everything, forgot my network, created a new location... I've been trawling the Internet on my iPad for hours at a time looking for a solution, but there is nothing. Every single problem I've encountered seems to have a different cause, or their computer is different etc.
I am very, very reluctant to mess with my system settings so please don't suggest I go in and edit system files because I'd mess it up!
I am using 10.7.5 and my iMac is early 2009 20". I am with virgin media and cannot connect via Ethernet due to where the modem is placed. Is nearby, but plugging it in would mean wires trailing across the top of the stairs which would be dangerous!
Cn anyone help? I tearing my hair out! Tank you!

Some users with various Wi-Fi connection problems have reported that they were given the following instructions by Apple Support, sometimes with success. I can't vouch for this procedure myself. After completing the procedure, you'll have to recreate all your settings in the Network preference pane. Make sure you know how to do that before you begin. Taking screenshots of the preference pane may be helpful.
Step 1
Back up all data.
Triple-click the line below the line you're reading now to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 2
Reset the System Management Controller

Will my US iMac early 2009 work in South Africa?

I am moving. I know that mobile and portable devices will work, but will a desktop? I do not see voltage guidance on the iMac casing.

Yes they are also 100-240V AC, see > iMac (Early 2009) - Technical Specifications
However you may need to find a power cord with the correct plug end or a plug adapter depending on the outlet configuration there.

IMAC early 2009 2GB RAM, 2.66ghz Intel Core 2 Duo, Im currently running Snow LEopard 10.6

So I have an iMAC early 2009 2GB RAM, 2.66ghz Intel Core 2 Duo, Im currently running Snow LEopard 10.6 & I tried upgrading to Yosemite 10.10 today and right before it finishes it cancels download and says unable to download application "NSInternalInconsistentexception" ??? how do i fix this

Mavericks is no longer available from the App Store, so your choice is Yosemite. One option is to create a new partition (~30- 50 GB), install the new OS, and ‘test drive’ it. If you like/don’t like it it, you can then remove the partition. Do a backup before you do anything. By doing this, if you don’t like it you won't have to go though the revert process.
Check to make sure your applications are compatible.
