Radeon 2600 Fan Noise

Hello
I had an issue with my new Mac Pro, where the Radeon 2600 Fan was running eratically, even without any load on the card. It sounded like an engine reving up. It then settled running at max speed, which was very noisy.
With the help of Tech Support the problem was resolved, however the fan is still too noisy for my liking, and I was thinking of using a passive cooling solution.
Has anyone done this, and what passive unit will do the job.
Thanks

Get the card replaced would be first thing to look into. There were problems with the firmware update process; and problems with many of the retail 3870's which seem to be okay now. Manufacturing problem.
There are some kits but you should not need one on a 2600.

ATI 2600 Fan Noise

My new Mac Pro is fantastic, and pretty silent, however working away last night, I noticed an occasional irritating whiney woosh coming from an internal fan. On inspection it turned out to be the fan on the Radeon 2600. It spins normally, but every 10-20 secs accelerates sharply, giving a whooshing sound.
The machine has 16GB RAM filling all 8 slots, 4 HDs in the normal bays, and a MaxConnect kit with 2 further HDs in the lower optical drive bay.
I'm wondering whether the machine is running a bit hot because I've maxed it out, but then none of the main fans are speeding up, apart from the Radeon fan it's almost silent.
Any ideas?

I have no idea.
In the past, you could look up "utility" fans for a computer cabinet from the part number sticker on the fan itself. This often gave you a link to industrial fans available ONLY in the handy 1000-pack. If they managed to blurt out the air moved in Cubic Feet per Minute, you could use that to find replacement fans of the same size, prefereably with same of lower sound generated in deci Bells.
Because of custom housings, Graphics card fans may be a specially-built item rather than a standard commodity part, so replacements (if any) may only be available from the manufacturer.

ATI Radeon 4770 Fan Noise - Any bright ideas?

Hi,
I've an ATI Radeon 4770 graphics board installed on my Mac Pro (Early 2009, 16 gigs of RAM, OS 10.6.8). The board works fine but the fan is noisy and goes on full tilt from a cold boot. If I restart the Mac Pro then the fan will slow down and stop. This is my current workaround. Other than fan noise problem, everything else is working.
Here's what I've done to troubleshoot so far: Reset the SMC, zapped PRAM several times. Updated OS to 10.6.8 from 10.6.7. Verified HD and disk permissions. Extended Hardware Test has been passed.
Anyone any other bright ideas?
Thanks,
Midi.

Brand new?
Then you should be talking to the Vendor about why the card they sold you does not work correctly.

ATI Radeon 2600 XT Fan Noise

I just received my new Mac Pro on Friday - it shipped with 10.5.4 installed. After looking at some of the new features of Leopard (had only used Tiger previously), I installed all the available updates -- these were:
Mac OS X Update 10.5.5
Aluminum Keyboard Firmware Update 1.0
Java For Mac OS X 10.5 Update 2
iTunes 8.0
Digital Camera Raw Compatibility Update 2.2
QuickTime 7.5.5
Remote Desktop Client Update 3.2.2
Front Row Update
All the updates were successful and no issues were apparent until this morning. The fan on the graphics card (ATI Radeon 2600 XT) now seems to be running at full speed, regardless of what is running. Just idling at the Desktop the fan still runs at full speed. A soft reset of the SMC has also been done - no change. Is this a known issue? Is anybody else experiencing this? I've also posted my temps below:

I don't know what is happening with ATI, at first I thought it was the consolidation and merger that affects products and Q&A, but the X1900, then the 2600XT, and even the 3870's fans and noise (which after 3 months seems to be better now on the 3870 with the latest models rolling out).
Normally I would expect a new or even ref'd unit would have the latest fixes and if there still are problems... then there aren't any solutions? One person dropped into Vista and reduced fans to 20% setting and it works even under heavy loads w/o getting above 80C.
Seems like the Nvidia 8800GT costs more, doesn't have the drivers optimized for OpenGL just yet, but runs quieter.
One person complained theirs would making an annoying "up-down-up" fan revving constantly.
A copper cooling kit isn't a option user should have to invest in. Not sure it works with 2600 -
"The Accelero S1 Rev. 2 dramatically extends the compatibility to many of the latest graphic cards. It supports high-end to main stream graphic cards including the latest hot selling Radeon HD 3870, 3850 , GeForce 8800GTS (G92) and 8800GT. http://www.arctic-cooling.com/vga2.php?idx=147

ATI Radeon 2600 graphics artifacts

I have a new MacPro with the ATI Radeon 2600 in it. Occasionally, (perhaps 3 times in 5 months)the screen will go completely wacky, with the whole screen turning like a tie die, except not as cool. A restart seems to fix the problem. Right now I am running EFI firmware version 01.00.236. There is an update (to .252) that I have been avoiding because of the increased fan noise and other complaints I have read about, I was hoping for a newer firmware to be released.
Are there MacPro users who have had the card issue, and had it fixed by the new firmware, and is there issues with the .252 firmware that make it worth avoiding?

I'm experiencing issues with my new Mac Pro as well, bought it this month. It has the default everything except I've added 8GB OWC ram. Everything passes apple hardware test, multiple times, but a few times now my open windows (all applications) have become "messed up". For example, this is Safari:

Is this similar to what everyone is seeing?

T530: Unbearable fan noise

Probably similar to this thread, the T530 I recently received has fan noise issues. I've invested considerable time in solving this, but found that a solution can be achieved with reasonable effort only by Lenovo:
Introduction:
Most ThinkPad models do not provide the operating system (or the user) the ability to set the fan speed directly (e.g. in rounds per minute) or in a fine-grained way (e.g. as a percentage of maximum speed). Instead, there are "fan speed levels", usually 9 levels (level 0 through level 7 as well as the level "disengaged"). For each level, a particular fan speed is defined and the Embedded Controller tries to achieve this particular fan speed by measuring the fan speed and adjusting the electrical properties of the fan (e.g. voltage or pulse length or something like this).
The fan noise problem:
Every time the internal temperature sensor reaches 50 °C or so, the fan starts with about 1900 rounds/minute and then quickly goes to about 2737 rounds/minute, where it is loud. Then it takes about 20 seconds, the temperature drops to 45 °C, then the fan is switched off. Then, after maybe other 30 seconds, the cycle repeats and the fan is switched on again, ...
There are major problems with this behaviour, because:
The fan is not running continously, but pulsating.
The fan is running at level 1 at a much higher speed than needed, creating unnecessary noise.
I have measured the individual fan speeds for individual fan speed levels:
The fan speeds at different levels are as follows:
Level 0: 0 rounds/minute
Level 1: 2737 rounds/minute
Level 2: 2944 rounds/minute
Level 3: 3033 rounds/minute
Level 4: 3074 rounds/minute
Level 5: 3597 rounds/minute
Level 6: 3773 rounds/minute
Level 7: 3773 rounds/minute
Level disengaged: 4754 rounds/minute
Solution draft:
A minimum solution to the problem above would be introducing another fan speed level between 0 rounds/minute and 2737 rounds/minute, with about 1900 rounds/minute. The reason this makes a difference is that there is a fundamental difference between laminar flow and turbulent flow, where the laminar flow makes nearly no noise and the turbulent flow makes a lot of noise. (Whether an airflow is laminar or turbulent is easiest influencable by affecting its speed.)
As you can see on the observed mapping from fan speed level to fan speed, level 6 and level 7 map to the same speed.
Thus, no particular fan speed would be lost if the mapping would be changed to the following:
Level 0: 0 rounds/minute
Level 1: 1900 rounds/minute
Level 2: 2737 rounds/minute
Level 3: 2944 rounds/minute
Level 4: 3033 rounds/minute
Level 5: 3074 rounds/minute
Level 6: 3597 rounds/minute
Level 7: 3773 rounds/minute
Level disengaged: 4754 rounds/minute
Solution implementation by user is impossible:
The problem, however, is that, while a user can decide which fan speed level should be active at a particular time, the user cannot decide which fan speed should actually be achieved for a particular level. Thus, the user can either decide to have 0 rounds/minute (which is not particularly sustainable, because the equipment becomes hotter and hotter) or to have 2737 rounds/minute (which is not particularly sustainable either, because both the user and other people arund the user's Lenovo computer are distracted from work).
The mapping from fan speed level to fan speed is actually stored in the Embedded Controller Programm ("ECP"). This Embedded Controller Programm is freely changeable or configurable by the user. Only Lenovo has the source code to this Embedded Controller Programm, and actually only Lenovo may know how to disassemble such a binary Embedded Controller Program in case the user wanted to change it. Thus, even advanced users cannot fix this problem by fixing it where it should be fixed.
It should be noted that, because fan speed is a long lasting issue at Lenovo, a third party has been even developed an after-market hardware solution: TPFC. However, this solution probably voids the warranty, and it work arounds the problem at the wrong place, and it costs time and money and effort to actually install it.
Only Lenovo can fix this problem:
How Lenovo should fix the problem
Thus, this is my call to Lenovo to fix this problem (at least for the T530 series, but probably W530, T430 are also affected). Ideally, the solution should be as follows:
Change the Embdedded Controller Program such that the mapping from fan speed level to fan speed is as follows:
Level 0: 0 rounds/minute (no noise level)
Level 1: 1500 rounds/minute (low noise level, sweet spot)
Level 2: 1700 rounds/minute (low noise level, sweet spot)
Level 3: 1900 rounds/minute (low noise level, sweet spot)
Level 4: 2100 rounds/minute (some noise level)
Level 5: 2600 rounds/minute (high noise level)
Level 6: 3100 rounds/minute (high noise level)
Level 7: 3773 rounds/minute (high noise level)
Level disengaged: 4754 rounds/minute (high noise level)
The reasons for this fan speed design are as follows:
The "sweet spot" where both the fan will run most of the time and where the user would not complain is between 1500 rounds/minute and 2100 rounds/minute. If the fan needs to be faster to keep the system cooled, then the user is likely to run the system with considerable load to CPU or GPU. In this case, there is no option to reduce the fan speed, but also in this case, the user probably accepts the fan noise for the computing power delivered.
The "sweet spot" in terms of CPU load is where the users do not accept fan noise while actually generating only minute CPU load (e.g. during web browsing or writing documents, where the CPU and the GPU is mostly idle). For many users, this is their normal working state (e.g. working in a quiet office, a very quiet library, a quiet bedroom, a quiet boardroom, ...). These scenarios are where Lenovo ThinkPads currently fail to deliver, unnecessarily
The "sweet spot" needs higher resolution (more fan levels allocated to these fan speeds), because slightly different load patterns may make it necessary to go from one level to the next higher level, but then the next level still should be bearable. Conversely, the higher levels (e.g. from 2600 rounds/minute on) do not need such a high resolution, because for most of the users, these levels will be only attained rarely anyway, and then they are accepting the noise.
Currently, there is no fan speed level at the sweet spot. With the proposed fix, there would be 3 fan speed levels at the sweet spot, with a neighbouring fan speed level (2100 rounds/minute) still being bearable when considering the performance delivered.
There is no fan speed level below 1500 rounds/minute. This is ok, because the fan is nearly inaudible at this speed anyway, and below a certain speed, there is a risk (depending on the fan) for the fan to actually not rotate at all (e.g. due to friction).
How much time and effort would Lenovo need for fixing the problem:
The Lenovo engineer responsible for the Embedded Controller Program of the T530 should need less than one day to change the source code of the Embedded Controller Program and to recompile it. The engineer may need one additional day to test this program (e.g. for different types of fans), and there may be a need for an additional day to release the update to the BIOS and ECP. All in all, Lenovo should not need more than 3 engineer-days (maybe worth 1800 USD) to fix the problem.
Why Lenovo should fix the problem:
Probably the whole current T series (T530,T520,T430,T420) as well as the current W series (W530,W520) fails the users in any of these scenarios (among others):
User working in a quiet office.
User working in a quiet library.
User working in a quiet bedroom.
User working in a quiet boardroom.
Thus, the Lenovo T series is currently not usable for many business users and almost all students. This problem should cost millions of USD of revenue, while fixing it would cost it maybe 1800 USD.
Incidental remark: Lenovo subsidiary can do better:
Lenovo has bought the majority of the Germany consumer electronics company Medion. Medion currently offers a consumer level notebook "E7222" for 499€ including German VAT. Despite of this low price, this notebook delivers very good fan control (that is: the notebook is nearly silent when the CPU is near-idle). (However, being consumer-grade, it does not offer a docking-station or a FullHD screen or WWAN.)
What will I personally do:
Some weeks ago, I had a powerful W530. I returned it due to fan noise for cash refund. Now I have the T530 (Serial number: R9RRF26) which has exactly the same problem. The deadline until I can legally request a cash refund runs until 2012-09-07. I hereby ask Lenovo:
To fix the problem and release an ECP or BIOS update until 2012-09-06 (it is doable, see above) or
if the problem cannot be fixed in this time (e.g. due to bureaucracy): provide me with a written statement (e.g. e-mail or forum post is sufficient) that my legal cash refund deadline (German law: §355 BGB) will be voluntarily extended by Lenovo (to some date Lenovo thinks it needs to fix the problem).
If none of the above happens, I will have to return the T530 as well. This is the 2nd chance Lenovo has gotten from me, there will be no 3rd chance. I would have to turn to Fujitsu (they do have business-class machines with big batteries, FullHD, WWAN) and they probably have better fan control.
Solved!
Go to Solution.

kaawee,
Thank you for the considerable thought that you put into your summation / analysis and proposal for a change.
I don't agree that you are wasting your time as we did make EC changes on the X220 and T420s to change fan behavior (along with several other systems). However, not all customers agree that the changes made the system behave the way they wanted and were completely satisfied (hence some of the dissenting opinions expressed here).
We are interested in feedback on T530, W530, T430 fan concerns and we are investigating. It is possible that a future change might be made, but I cannot say for certain that it will, nor can we commit to making this change within 4 days (2 now remaining) from your original posting.
Best regards,
Mark

ATI Radeon X1900 XT Noise levels

Hi,
I'm considering a Mac Pro + 4GB RAM + ATI X1900 XT to run Apeture, based on the experiences & recommendations in this forum.
Can anyone comment on the noise level of the ATI X1900 XT compared with, say, the standard GeForce 7300 GT? I use my current Mac to run iTunes, as well as some other sound based apps that would suffer if the graphics card noise level was like a jumbo jet on final approach.
Does anyone have experiences here they can share?
I read in the forum that there is a possibility of a ATI Radeon X1950 XTX for Mac Pro that is quieter ... any truth in that?
Much appreciated.

Can anyone comment on the noise level of the ATI
X1900 XT compared with, say, the standard GeForce
7300 GT? I use my current Mac to run iTunes, as well
as some other sound based apps that would suffer if
the graphics card noise level was like a jumbo jet on
final approach.
I have a MacPro 2.66 with the X1900 which was preinstalled in the system. The card is quite noisy but it is at an acceptable level. The reason you hear it is that the MacPro itself is very silent. Two components are competing which can make more noise: the harddisk (standard model with 250 GB) and the X1900. :-))
The sound from the X1900 is a constant fan noise which you are able to ignore while you work with this awesome machine. The performance of Aperture is simply great with this card even if I just installed 1GB of RAM!
Let me say it this way: If you want great performance for Aperture you should arrange with the fan noise of the X1900. Im convinced that we will see much more silent cards in the future which will give us the same performance. Then the time for a nice christmas present will have come! :-))

No video, high fan noise on startup, for the THIRD TIME

For the third time in slightly less than three years, I have encountered the same crippling problem with my iBook G4 (1 GHz, June 2004 vintage). In essence, the screen will abruptly go black while in use (not screensaver) and no amount of keyboard/mouse activity will reactivate the display. If I power off by holding down the power button then restart, the screen stays black and the fans come on full speed.
Despite a bit of confusion on the details, this sounds like the problem described on the webpages below. In essence the Danish government has issued a finding that there is a design flaw which allows excessive logic board flexing, which in turn causes logic board failure.
This is, as I said above, the third time I have encountered this failure in less than three years. Worse, they seem to be coming closer together. The first was after about 1.5 years, the second 9 months later, and now seven months after the second repair. Since I didn't get Apple Care, paying for a third repair out of pocket would bring my repair bill up to the cost of a new iBook.
I do not abuse my iBook, and since the second repair I have been very careful with my iBook. Does anyone have any suggestions on getting Apple to acknowlege the problem or who I can appeal to? Apple's website doesn't seem to offer any e-mail tech support options and I'd rather not sit on hold for an age (again) if it can be avoided. While I don't want to abandon my iBook or Apple, I may be forced to if I can't rely on the hardware.
Thanks

iBook G4 1GHz (early 2004) Mac OS X (10.3.9) blank screen, high fan noise on start

Well it doesn't sound like the Danish power problem since it will start up.
The ATI Mobility Radeon 9200 4x AGP graphics processor chips in these iBooks have been problematic. Usually it's the reball problem and it can be reballed for ~ $78. I've done 4 this year and they work just great. A cheap way to get nice laptops. If they respond to the "shim fix" then reballing will work.
A more troubling problem is with the 9200 chip itself. My reballer says that this chip is in itself the cause of some of these problems. He knows it since it's also used in IBMs, Compaqs and many other laptops and he's seen a lot of failures. My only failed reball was a 9200. I have a line on a replacement board or finding the chip in a broken PC.

Loud fan noise on mountain lion, Mac Pro early 2008

Hi there,
I've recently installed mountain lion 10.8.5 lon my Mac Pro , early 2008, 2,8 GHz, 24 gb ram, 2x ATI Radeon 2800 XT.
To give it a clean shot i clean installed it on a sep. Partition, no upgrade from my previous Snow Leopard.
The Machine usually works quiet, i've measured via Isat Menu:
exhaust fan: 681 rpm
HD/expansion: 1100 rpm
After running Mointain Lion, latest update version, i get a much louder fan noise than in snow leopard:
exhaust fan: 845-950 rpm
HD/expansion: 1500 - 1800 rpm
The activity monitor shows no significant CPU usage, only the kernal has over 90 threads constantly running.
I've heard that this is a known issue but it's never been resolved. SMC and PRAM reset did not work at all.
when i go back to snow leopard everything gets back to normal. Yosemite is even harder on fan noise than mountain lion
so i've rolled back to mountain lion.
Any idea ?

no one here with the same problem on an early 2008 Mac Pro ?

But of course the chipset in your question is a VIA***! Meaning:
Go to your mobo's home page and update 4in1 drivers, and do it while in Safe Mode I suggest. By the way, it is a 9600 you have, isn't it, like me without the fan perhaps?

Thanks for your reply . I actually just now figured out what the problem was. While I had updated my BIOS, I had completely forgotten about updating my Chipset. I have the Intel 865PE chipset, so I went to Intel's Website and downloaded their "Chipset Software Installation Utility (INFINST.EXE)".
After the installation and a reboot, PRESTO!!! AGP Speed at 8x and Fast Write is on, woohoo.
Thanks again for your response , and I hope this post helps some people with a similar problem. Later all."

Fan noise when screensaver starts

Hi
I've been reading about this issue but don't find any post that relates fan noise with screensaver.
I had fan noise problems similar to some posted... things got better,but now it only becomes unbearable when the screensaver starts.
Any ideas ?

I'm experiencing the same issue since I've replaced the standard Nvidea for an Ati Radeon HD3870 video-card. When the screensaver starts the noise of the fans increases. Don't understand it since it's just the solid colors effect.. :-s

Problems with new Yoga 2 Pro (battery, fan noise, yellow, screen orientation, on-screen keyboard)

I purchased the Yoga Pro 2 on Thursday October 17. I love the computer for so many reasons, (especially since it replaces my 4 year old Compaq that was 6.5lbs!) however, I am also having a few issues with it.
It is the i7/8GB/256GB model from BestBuy. I am experiencing the same yellow issue as is mentioned by many on here. I didn't realize it, though, until reading these forums and then comparing to my old computer and my ipad and iPhone. A little disappointed, though it looks like Lenovo may be working on a solution.
But the real reason I originally came to look at this forum is because of 2 things: my fan and battery.
The fan (on the right side of the keyboard) is always on! I didn't expect this, and am wondering if mine is a lemon or if others are noticing the same thing. It's pretty noticeable, especially in a quiet room. I was showing off my new computer to a friend and the very first thing she said was that it was loud! She was using a MacBook pro, which wasn't making any noise at all.
The second thing is the battery... I am attaching 4 photos all taken within a few minutes of each other. If you cant see them, they are all of the battery meter on my screen. I am listing the time of day (to show how much time passed), percent remaining, and time remaining:
10:04 (88%) 306 hr 15 min
10:05 (88%) 8 hr 48 min
10:09 (86%) 4 hr 54 min
10:29 (81%) 5 hr 12 min
I feel like my computer just cant make up its mind!!
Another issue I had... I turned on my computer to show it to a friend (same friend who said it was noisy) and the screen image wouldn't flip when in any of the modes. This means I showed her the stand mode with an upside down image. Even in tablet mode I couldn't get it to flip. I turned the computer off and then on again, and luckily it decided to work, but it was frustrating, and I hope it's not something that becomes an issue.
Also, when I have the computer in tablet mode, the keyboard automatically pops up when I click somewhere to type... but this doesn't happen in stand mode or tent mode. Is this normal? I would have thought that the keyboard would appear in any of those modes, since the real keyboard is not accessible in any of them. And of course now that I am testing it out while writing this, none of the modes (including tablet) is having the keyboard come on screen. Of course, I know I can always choose the icon on the task bar to bring up the keyboard, but it would be nice if the computer did it automatically since it knows there is no other keyboard accessible in those modes. Is this an issue anybody else has had?
I really do enjoy using this computer, but some of these issues really need to get worked out if I am going to keep it. I'd love to hear if anyone is experiencing anything similar, and if there are any good fixes!

I just got a Lemontine Yoga 2 Pro i5/8GB/256GB from lenovo.com and the silver one from BestBuy in the same configuraiton. The silver one has no issues except for the crazy number of hours remaining on the battery which is fine, doesn't bother me. The fan noise is very quiet, and you can only hear it if you put your ear up to the vents in a quiet room.
Now the Clementine one...It was heating up pretty good. I put my ear to it on many occasions and can hear nothing at all, the fan is either missing LOL or doesn't work. I had an issue where I left the thing on for 4 hours, but sleep is configured after 5 hours. When I tried to use it, it showed me the screen brielfy, then blank. Tried hard reset, called Support, nothing. Support says its dead. Ok, an hour later, it turned on. I'm guessing it was too hot and was in some mode to protect itself, like a smartphone that is left out in the sun for some time, it won't power on till its cooled down.
I'm still in process of trying to get a hold of Lenovo to swap it, but since they no longer sell this configuration, I doubt they'll be able to get me a new one.
The silver one from BestBuy us solid though, love it, best in class in my opinion...actually got it from Future Shop sorry...from Canada, but they're essentially the same store.

HP TouchSmart 610-1280qd CTO Desktop PC Fan Noise

Hi,
Can you tell me if a loud CPU fan is normal for this computer?
The CPU fan is working very hard and the CPU and GPU are all ~38 degrees Celcius. The bios reports 1100 CPU Fan Speed and 3800 system fan speed. It sounds like my CPU fan is actually spnning faster than that.
Thanks
SOLVED: I spent some time with technical support and they had a model in the lab and confirmed that the loud fan noise is not by design. I returned my Touchsmart and received a new replacement and it is almost silent. I checked the BIOS and the fan speeds are reporting 1100 CPU Fan Speed and 2100 system fan speed with the same low temps above. I believe in my original machine they did not install fans right by swapping the plugins on the motherboard; I do not have solid evidence of this though.
I hope this help and just know that these machines should be very quiet most of the time other than some low level harddrive access noise.

Hello sal4303. I understand your screen is going blank.
Have you tried changing the settings for how long it takes your monitor to turn off? Here are the instructions.
Let me know if this has an effect on your issue.
Have a lovely afternoon!
Please click the white star under my name to give me Kudos as a way to say "Thanks!"

Big fan noise problem: the rear fan won't shut off, the BIOS won't update, systemupdate locks up

I received new ThinkStaion (oh boy, lots of memory and CPU speed, yay!)
I unfortunately left the originally installed Vista OS on there. Very much regretting that as I believe it contributes to the following problems (BIOS).
So the original problem was that after just a month of using my new ThinkStation, the System Board died, and it had to be replaced. Honestly, all I did was choose the sleep or hibernate option in Vista to shut down. Afterwards,poof! didn't even get the proper Power lights on the system. I diagnosed this with the online docs and then sat for a few hours on our tech support line doing all the same things to re-diagnose it.
So after the replacement, the rear fan will not shut off. Jet engine noise all day. I went into the system settings and selected "Quiet" for the Fan settings but that did not help.
Research on this forum resulted in the possibility of a BIOS update fixing the problem. Comparison to my co-workers systems which arrived at the same time shows this BIOS is woefully out of date, so even if it does not fix the fan issue I want to update it. However, everything I've tried to do is failing for one reason or another.
(The fan issue does need resolution since in one week I will end up sharing an office (first time in many years, thanks IBM for nothing!) so since I don't want us both to have to wear noise cancelling headsets, I'd like to fix this without having to just pull the @#$@ power to the fan. Grrrr. )
I downloaded what I felt were the appropriate Lenovo apps to update both the BIOS and the serial number but none seem to work properly from the command line in Vista. One of the two (can't recall which) asks me to reboot and it never actually shuts down. Eternal "Shutting Down" message. Ga! The other throws some gosh awful

Then I decided Vista might be the problem and found sites recommending flashing the BIOS from a bootable USB. So I started down that path and after burning the wrong version, finally geting the AIK Vista tools installed and to the point of trying to make the USB bootable, it won't allow me to put the OS boot on it. Ah, for the days when a simple "sys a:" took care of that.
So, after reformatting the USB and pounding my head in the wall, keyboard, etc. I am at my wit's end. What to do. I just want the fan noise to go away.
This does seem to duplicate other forum messages but I can't get anywhere on this. Help!
Solved!
Go to Solution.

FYI to all the helpful folks here (and any looking to shut their jet engine off as well): Flashing the BIOS did the trick.
First I had to find a website with DOS OS files and put those on the USB instead of Vista. Oldie but a goodie, but at least it booted! No other versions would.
I had been intending to use the WinPhlash utility that Lenovo supplied with the BIOS update but since I was booting from DOS that was useless. However, I found a DOS version of it and used that instead. Boom baby! Flashed and rebooted.
It did take two boots to get it back to normal (first one gave very alarming messages about no operating system being found but I think it was just a remnant of the reboot that was triggered from the DOS session). A second boot returned life to normal and blissful silence from the server. And I was finally able to get the model and serial number back in there to get rid of the bootup message it throws for that too.
Ahhhhhhh.
Thanks to all for the hints - I believe I had gotten the idea of flashing the BIOS to solve this from some other thread I found here. This is a very nice forum to have bookmarked.
