Ideal fan speeds for a 20" iMac

Hi,
I have a mid 2007 2 GHZ 20" Intel iMac, I recently had some unexpected shut down issues which I traced to a defective optical drive fan. I have SMC fan control loaded and it tells me that the DVD fan went off-on-off-on, I also ran an extended hardware test and that confirmed the bad fan, I replaced the fan and that was the end of my problems. However, I have been fooling with the fan speeds and now I am wondering what the ideal speeds for all three fans in my machine are? Can anyone help?
Thanks,
Rolly

I think you have to balance the need to run cooler against running the fans so fast you wear out the motors quickly. In general, it's probably best, at least for prolonged periods, not to run them any higher than maybe ~400 rpms above the defaults. But that's just my own guess. I don't have any statistics on what fan speeds are ideal for attaining that balance.
Then again, fans are much cheaper to replace than drives, logic boards, or power supplies.
I have maybe 5 or 6 pre-sets, including the defaults. This is one setting I often use in summer, but I may sometimes go a bit higher in very hot weather. I also have a fan running at the back, which helps keep the internal temps lower and allows me to run the internal fans slower than I would otherwise. In extremely hot weather, it's pointless to blow hot air around faster. When it's like that I sleep the computer more often.
These are the defaults on my 21.5

Ideal fan speed for retina mac pro

Dears,
Kindly need information about idel fan speed for MacBook Pro (Retina, 13-inch, Mid 2014), I feel on my right side the fan is running continuously.

The fan always runs continuously. Typical idle speed is around 2000 RPM. Maximum speed is around 5-6000 RPM.

What's normal range temperature and fan speed for a 27" iMac?

I have a new iMac (27-inch, Late 2013), 3.4 GHz Intel Core i5, 8GBs ram, and NVIDIA GeForce GTX 775M 2048 MB.
Smc fan control reads up to about 131°F and around 1200rpm fan. Is this within normal range? At what point should I be worried?
Thanks

1200 rpm is the minimum fan speed according to iStat Menus and other sources. If your fans are at the minimum that means your system is not concerned about the temperature. On my system currently the fans are at minimum (1199rpm) and the temperature is 104°F. The room ambient temperature is 74°F. Your system looks normal to me. By the way, my system is also a 27-inch late 2013 iMac with the 3.5ghz I7 CPU. The Haswell CPUs are very efficient and low power.

Is there an utility for monitoring cpu/gpu temperature and fan speed for desektop m9200T?

My desktop computer m9200T running Win7 Home Premium crashes often. It seems to be temperature related.
I had tried SpeedFan, but my computer crashed everytime I ran it. SpeedFan window scrolled 20 some lines of text than the computer crashed. Is there an utility for monitoring cpu/gpu temperature and fan speed for desektop m9200T?
This question was solved.

Hi,
Only have one temperature monitoring application running or you could end up with erroneous readings.
Try PC Wizzard. Depending on your hardware, you should see temperatures for CPU, GPU and disk. At the same site you can also try HW Monitor.
I am running a custom motherboard and it comes with its own software for this purpose. HW Monitor seems fairly complete.

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.

Temperature and Fan Speed for 13inch i5

What is the normal temperature and fan speed of the early 2011 13inch MBP while using for a normal use (surfing the net, play music via itunes, movie via quicktime etc?
What is the highest/hottest temperature and fan speed of this MBP while using heavy load like photoshop CS5, playing games etc?
Thanks in advance!

Mine (13" i5) reaches 95C whilst watching hulu and browsing the web. Seems a tad high to me for what I am doing.
Hopefully you will get some more good answers.

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!

Does MSI 5850/70 have 100% fan speed for 2-3 secs when turning computer on?

Hi,
I currently have radeon 4870 and would like to upgrade to dx11 hardware. I seems that there are a lot of 4870/5850/5870 cards with stock coolers having this feature: they spin fan at 100% for couple seconds when I turn conputer on. And I don´t really like it. Question is, does MSI 3-in-1 High Efficiency Fan behave similarly on 5850/5870 series? If it does, can it be turn off using Afterburner or BIOS modding?

Yup, all new(er) cards do it, from any brand/manufacturer, so its not just an MSI thing.
And no there is no way to turn it off, unless you can write bioscode, or perhaps mount a different aftermarket cooler.
But why do you want to turn it off, like mentioned, they do this for a reason and its only a few seconds.
Ive said it before and I say it once, the sound is too short and too high pitched to wake people up, unless they sleep next to the computer.
Also, if you mod bios, or mount an aftermarket cooler and some goes wrong, bye bye warranty.

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.

IMac Fans speed

Can i let my fans of my iMac late 2013 27Inch, 3.2GHz quad core, 1024VRAM, 8GB ram
to run at 2640RPM? because i am playing some games and it gets too hot, but i am also worried about the fans speed if they could handle it to work every second day for 5hours at that speed?

Default idle speed is the speed of the fan when the hardware doesn't require additional cooling. You can't go by these, since these default speeds are for this model only, but for my 21.5 iMac, the first screenshot shows the default fan speeds for three fans, and the second shows the speeds I use as a pre-set (from smcFan Control) in what I call the "hot" setting. I don't normally go much above these speeds, and if I do, it won't be for very long. But again, I have no idea what a realistic upper limit would be for your model. I just think that running the fan at 2K+ over long stretches, as you want to do, will shorten its life dramatically.
I try to run the fans only at the maximum needed for effective cooling. If I can't cool the computer sufficiently, and at reasonable fan speeds, I just sleep it. I also run a small fan at the back of the case, which helps keep the internal temps down.
You should get some kind of temperature monitor. This one, may or may not work in your model. It's free.

User-developed Fan Control for the S10(e)

Hello and welcome.
When you've searched the internet and found this thread, it's possible that you are an owner of a Lenovo Ideapad S10 or S10e which has a little problem with the behaviour and/or the noise of the fan. In this post you will get all the informations you need to handle this problem for yourself. It should also be the same on every S9/S9e.
Just a few comments before we begin:
This is not an official support or solution by Lenovo.
We are just normal users as you are, but we get rid of the fan and wanted to find a way to handle it. So if you want to try anything of the methods described here you have to know that you'll do all this only at your own risk. We are not responsible for any damages of your device. You should only use these methods if you know what you are doing.
Please note that this thread is only for discussing, improving, trouble shooting and perhaps extending the fan control utilities. Any general complaints about the fan problem itself should be placed in the original thread right here: http://forums.lenovo.com/lnv/board/message?board.id=IdeaPad_Netbook&thread.id=795. It already has 80+ pages (the link goes to the first page) and it is better to exclude all the fan control stuff because there it's very difficult to keep an overview.
Here you may post all of your questions, ideas/brainstorming, concerns, thanks and so on and you are really invited to participate and be an active member.
In this first part of this post I'm going to summarize all information about using a fan control utility. For any newbie it will be enough to read this post to get all necessary information. The second part does the same for developement of fan control utilities as we still have no known or working fan control utility for Linux, Mac OS X and other OSs I've forgotten - for now.
For getting started you need a S10 or S10e with an up-to-date BIOS. For the S10 it's the 90 67, for the S10e the 66.
The battery issue
Under very specific circumstances - that we haven't figured out yet - it might happen that your Lenovo S9/10(e) no longer detects the battery while using S10FanControl or S10Fan. It might occur after 2 minutes, it might occur after 2 months, it might never occur. It does not occur using Notebook Hardware Control.
It can be solved by removing the battery, waiting 10 seconds and put it back in. Then the battery is re-initialized and the detection works again.
S10FanControl - Windows
The first utility is S10FanControl created by user dresslerc. The current version is 1.0.0.1, available here: http://www.mediafire.com/file/yd5xmnrnijf/S10FanCtrl1.0.0.1.zip. After you've downloaded it you just have to extract it and start the .EXE in the "Release" folder. Here are the notes and the description dresslerc posted right here:
Everyone,
I've uploaded a version which everyone can use to test with. Remember this is still a TEST version although I think it works for the most part. It should work both on the S10/S10e.
Please install the .NET Framework 2.0 or later first.
Then click here to download the exe: http://www.mediafire.com/?jlg2enkjdxn
Once downloaded, extract the files and hit hte S10FanCtrl.Exe. Once this program launches you should be able to control the fan. Keep in mind that if you lower the fan speed then it'll take upto 30 seconds before the S10 registers the change, so be patient.
I've only tested this on the latest BIOS 59. I am sure it will work on the 57 as well but the individual speeds might not work properly on that version. Please try it out and report back.
The only issue that I heard so far is that occasionally the fan will kick in regardless if in Manual/Smart Mode. Also the temp it shows may not be accurate. If you find any other issues please let me know what they are so I can attempt to fix them.
Once we have all the kinks worked out then I will release the source.
Heres a quick Video: http://www.youtube.com/watch?v=_PKl70ZgmFg
REMEMBER: USE PROGRAM AT YOUR OWN RISK!!! I AM NOT RESPONSIBLE FOR ANY DAMAGES THIS PROGRAM MIGHT CAUSE.
Application Use:
BIOS Controlled - Fan is controlled by the BIOS
Smart Mode - Fan is controlled based on the conifguration in the options. You can set the threshold here at what temp you want the fan to kick in...
Manual - Fan is controlled manually by the slider.
If you want to have the program startup automatically, then place a shortcut of the app in the PROGRAM FILES -> STARTUP folder. Then you may want to go to the options and make the application minimize at startup.
Edit:
It seems there are some issues with the app and the S10e or previous BIOS versions. Will post a fix asap.
The source code for S10FanControl is available here: http://www.mediafire.com/?sharekey=7a3fb99d33817c08c2b435915e8821d7e04e75f6e8ebb871, written in Visual Basic .NET 2008.
S10Fan - Windows
The second utility is a tool written by user slash:
Hi guys,
Well it looks like Lenovo dropped this matter after all. Anyway, I have here another fan controller to add to the bunch. I have been using it for some time now without any problems. It is for both S10 and S10e.
What the program does is basically the same as others. The S10's fan speed is controlled according to the ACPI thermal zone temperature. By over writing the values which resides at offset 50h of the EC register at an appropriate timing, the ACPI thermal zone temperature is over ridden. The program is written in C and uses WinIo created by Sysinternals. The GUI version is available now.
It should be noted that the fan speed temperature thresholds differs with BIOS version. For 14CN67WW and 14CW90WW the fan changes speed at temperatures 60c, 65c, 70c, and 80c. Furthermore, the BIOS will automatically shutdown the S10 if the temperature reaches 90c.
The program has a fail safe mechanism that automatically disables itself if the actual ACPI thermal zone temperature goes above 85c. This allows the BIOS to regain control and the fan will work as intended by Lenovo. If the temperature drops below 85c the program will take over control again.
To run the program, you will need administrative privileges.
Known working BIOS versions: 14cn58ww, 14cn60ww, 14cn67ww, 14cn90ww
The program will work with any BIOS version as long as the BIOS uses the 50h EC register readouts to control the fan.
build 2009.05.24
Higher priorities for EC commands.
Usage: The program will run in the system tray. Double click or right click and use the menu to open the program. To determine the BIOS temperature thresholds, use the 'Setup' button. To run at boot time, place a short cut in the startup folder.
http://www.mediafire.com/file/njhz0icym2t/S10Fan.zip build 2009.05.23

Notebook Hardware Control - Windows
The third utility is a profile for Notebook Hardware Control. I've adapted it from a profile for the Lenovo N500 which I've found here: http://nhc.yourcopy.de/overview/. With the manual for creating the profiles that can be found here: http://www.notebook-treff.de/board/database/hilfsprogramme-f%C3%BCr-nhc/92-how-to-create-an-acpi-fil... I was able to change the ACPI commands to work on the S10(e).
Installation and setup is divided in two steps. The program Notebook Hardware Control (NHC) is available at http://www.pbus-167.com/. Install the program, but do not start it for now. Then you need my NHCConfig utility, available here: http://forum.eeepcnews.de/download/file.php?id=1476. It detects your model number and BIOS-version via WMI and writes a proper S10(e) profile to the NHC acpi directory. The GUI is German if you have a German Windows and English if not. Additional languages can be added.
After you've extracted the ZIP-file you have to start the nhcc.exe (requires .NET Framework 2.0). At first a message appears that you use the program at your own risk. Then you can choose if you want to apply your own settings (experts) or if you just want the program to run with my defaults (newbies). In the settings window you can see your system details on the left, you can set up your thresholds in the middle and you can set the fan speed you want on the right. Then click on execute.
Now start NHC. Go to the "Settings" tab and click on "Show all NHC options and settings". Then a few more tabs appear. Go to the "ACPI" tab and check if the "ACPI Control System" is running (if everything works, the message "ACPI Control System running" will appear, otherwise it says "ACPI control system is not yet configured for this system"). Now click on "Show ACPI Control System details".
Here you can change the temperature values the fan control depends on (the settings from NHCC are the default values). On the bottom of the window you can see the "Current CPU temperature". That is the value you have to deal with. In general it has a value of around 60°C. In the middle you can see four user editable temperature values. You can leave the values as they are if everything works. The on/off values are responsible for the temperatures at which the fan starts running and stops again after cooling the device. The level values are responsible for the fan speed, for example you can set the off_level higher to let the fan run all the time at the lowest level, if the values do not fit for your device or whatever.
You can switch between NHC and BIOS control by disabling or enabling the "ACPI Control System" or by closing NHC.
Q:
A:
With every utility it is possible that it takes some time until you see an effect after you've started the program. Any failure of the programs should be no big problem because the only thing that should happen is that the BIOS controls the fan. Another issue that might occur due to the way the fan is controlled is that the fan may start running for a very short time and it looks like the fan control has lost control. The fan should stop immediately or at least after a few seconds.
Keep in mind that running the S10(e) with a fan control means that the S10(e) has to deal with higher temperatures. That could mean that the device will not last for 10 years but only 9 years (who uses a netbook so long...?). In every case you need a tool for monitoring your cpu temperature. We know that especially Core Temp 0.99.5 and Real Temp 3.00 do a very good job. That is important because the temperature values you need to set up the fan control are different from the values reported by the cpu sensor, they are between 15°C and 20°C higher. A normal temperature reported by the monitoring should be around 40°C, with the NHC default values the fan starts running at 52°C and stops at 38°C.

Q:
A:
END using fan control
BEGINNING developing fan control
Controlling the S10(e)'s fan is a litte bit difficult because it looks like there is no way to control it directly. But it is possible to manipulate the temperature the BIOS fan control depends on. As long as the built-in fan control thinks that the cpu is cool enough the fan stays off. And that is exactly the point where we can attack.
The fan control depends on a field called RTMP in the memory of the embedded controller. It can be accessed via "_SB.PCI0.LPCB.EC0.ERAM", the offset of RTMP is 0x50 (hex) or 80 (dec). It is a direct I/O read/write. The complete NHC command for reading the value is: ACPI.FIELD.ReadByOffset("_SB.PCI0.LPCB.EC0.ERAM", ref value, 0x50, 8) with "value" as the variable which gets the value.
What program logic do you need? You need a timer or something else that conducts an always-refresh cycle. It sounds very easy: You read the value, manipulate it and write it back. And it is that easy, you just have to keep some things in mind.
This refresh has to be done very often. The procedure must be very thin and quick. Also the bus that is used to communicate with the EC is a problem, but since the S10e BIOS 66 it became a minor problem for me because it looks like the built-in fan control now depends on some kind of average value over the last few seconds and it doesn't really matter if one write-cycle is failing.
The read-event must be placed before the write-event. Otherwise you just read your manipulated value. The field is filled by the system regularly, so you just have to test if the read_value is different from the written_value, then you know that the field was filled with a "fresh" value. Like "if read_temperatue <> written_temperature then real_cpu_temperature = read_temperature else do nothing".
About the values you have to write back... you will have to test and play a bit. My experience is that you can select three fan levels, starting at 59°, 62° and 70° - at least with the NHC profile and my S10e it's like that. It's some trial 'n' error. My fan stays off at < 59°, but you should select a very low value for fan_off like 30°. In my opinion it switches off much faster the lower the written value is. But it's just a feeling, I haven't measured it.

Great opening post Carsten!
The latest bios:
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-71252 (BIOS 66)
The FSB can be reduced from 133MHz to 100MHz using SetFSB, this also reduces the heat:
http://www13.plala.or.jp/setfsb/
clockgen = SLG8SP513V
If you add a shortcut to the startup folder the program will start at startup. Under properties you can change the target to:
"C:\Program Files\SetFSB\setfsb.exe" -s100 -b1 -cg[SLG8SP513V] -w20
So it starts with a FSB of 100Mhz, in the background, with the right clock generator, after 20 seconds.

Xorg 1.6, nivida drivers, and fan speed

I know the older nvidia drivers are not compatible with the new xorg, nor the nvidia-utils as I tried and found out!
I have 2 issues with this pc: I have a 6800gt nvidia card and the fan is constantly near 100% or close enough! I tried to install and run nvclock but it wont change the fan speed for this 6800 model. My xorg is below but I am not sure the drivers are working too good as the glxgears are only 140fps! I have a an older laptop with a smaller graphics card getting over 1000 fps!
NOW, before anyone gets excited I know glxgears is not the "best" benchmark, but its a decent one and accurate enough that I wont go from 140fps using it to 1000 fps using a similar bench.
I also tried to update the driver to the nouveau-drm driver but not sure if its installed or how to get it loaded in xorg. Any suggestions on these 2 issues?

Any suggestions on this nvidia issue?

Dell Vostro 1400 fan speed

I am not able to get lm_sensors to detect the fan speed, so I installed i8kmon and i8kutils and modprobe i8k force=1 to load the module.
Now the sensor applet tells me that my fan speed for Fan1 is around 27000 RPM and for Fan2 it's around 10000 RPM, while both cores of the CPU are around 50 C.
I've never thought of monitoring fan speed until today, but the figures just seem way too great...
I guess I am not doing it the right way. Any suggestions?

I have loaded this driver and added the newid=0x14e4 0x1713 but still
no luck. Still can not ping the Zenworks server or do anything. The
Network lights stay lit when it tries to obtain an IP address for eth0.
I read on another site that you need to update the initrd with the new
tg3.ko driver. I will try this later tonight and see what happens.
