Radeon 9800 Pro fan not working

Last Fall I purchased a used Radeon 9800 Pro card to install in my Sawtooth. When I finally got around to flashing the card with Mac-compatible firmware, and then attempted to use the card, I discovered that the fan was not working. As I recall, the card worked briefly under a light load, but could not handle a heavy video load. How likely is it that the card will work properly when I replace the stock fan (with the Vantec all-in-one -- BTW, thanks, japamac, for pointing that fan out as a space-saving alternative to the Zalman VF here:
http://discussions.apple.com/thread.jspa?messageID=7785260 ),
or is it quite possible that the card is fried and won't ever perform adequately again. Is it possible that I will install the new fan, only to learn that the card still buckles under a heavy load?

Hi-
With the 9800 Pro, if the card is run for any amount of time without a fan, the chances are good that the GPU is cooked.
How cooked, will only be shown by putting a fan on the card, and trying it.
but how to know whether this is the case beforehand?
Pull the fan and put a replacement on. That's all you can do.
Get a replacement bury frame fan, and replace the fan in the ATI heatsink.
If it doesn't work with a new fan, sell the set as junk on eBay.
You'll get, at least, the cost of the fan out of it.

Macbook Pro fan not working!!!

Macbook Pro Late 2011
13'

2.8 GHz Intel Core i7
I was walking around with my macbook and suddenly I hear a screaching sound. Please note that I was not moving my computer violently or anything, and I did not throw it. I did not know what it was at first, but found out later that it was my fan that stopped working. I realized this as my computer started to heat up a lot and applications started to be very slow. I then restarted my computer countless amounts of times and as a last resort, checked my SMC app that shows how quickly the fans are spinning. It says 0000RPM. I then got scared, and thought it might have been a problem with the application, so I tried to hear the fan. I could hear nothing but every 5 seconds I could hear two little thuds, which I guess is the fans trying to restart. I would like to know if there is any fix for this, or do I have to bring it to an Apple store. Thank you

Youd need to bring it into the Apple store, ...do NOT try to use it again, a dead fan can cause bad overheating and ruin things far more expensive than your fan.
Good news is, its a relatively inexpensive fix. sounds like the bearings are shot on the fan hub. Do you have pets or a lot of dust in your house, or do you ever block the fan input/output?

G5 graphics card error: ATI Radeon 9800 pro

Hi there,
The display on my mac has all of sudden gone haywire, there's bars across the entire screen that keep on changing colours/flickering etc, and when I try to drag open windows they become blocks of noisey colour.
So far i've tried resetting PRAM/NVRAM, ran the hardware test which picks up an error on the VRAM which is: 2ATI/1/4:113-A1440; ;16 (I think, it's very difficuilt to read properly), also pulled the graphics card out, given it a bit of a dust etc and put it back in to no avail. I've also tried plugging in another monitor which had the same problem.
I'm assuming my graphics card's fried, but I wanted to check on here to see if anyone had any other ideas. I'm slightly wary about splashing out on a new card when i'm not completely sure it's the card that's the problem, it could be the logic board for all I know. Also not too keen in taking it to the apple shop as it'll be away for up to two weeks, and I really need a working machine just now.
My specs are G5 single 1.8ghz, 512 ram, ATI Radeon 9800 pro card (not the special edition)
Apologies for the long message, and for any spelling mistakes as I can barely see what i'm typing, any advice most appreciated.

I would suggest first blowing compressed air all around the inside including logic board and video card (if you are adept at removing the card and reinstalling the better, careful not braking the AGP clip at the end of the slot that latches into the end of the card). Also keep the can upright at all times. This should help dislodge dust that build up over time and may cause overheating and unusual operation.
Then run Apple Hardware Test disc that came with your computer and run the extended test. It should at least help give you an idea if it's the logic board and/or video card. It's not 100% failsafe, but worth a shot.

ATI Radeon 9800 Pro and kt4 ultra

Hello
i was curious to know of any problems with the Kt4 ultra motherboard and the Radeon 9800 pro??
my system constantly crashes back to the desktop, or completely locks when i play Command & Conquer Renegade.
there are also some "misdrawn?" walls in the game also,...
i have all the latest drivers for the motherboard and the card,(including the released today catalyst drivers from ati.com)
i have also tried the drivers from driverheaven.net, but same thing happens,...
this is truly aggreviating...
some system specs:
kt4 ultra
antec 380 true ps
2500+ barton running at 11.5*173 @ 30c idle, 33c full load
corsair 2*256 3200LL
built by ati radeon 9800 pro 128mb
ive read where you can increase the agp voltage to try and fix the problem...and i also saw where one guy was just going to buy another motherboard b/c of the issues...
any help is truly appreciated
thx

FWIW, in case anybody is reading this thread in future and has problems with this Board and this card, I can report that I have now(at my second attempt) successfully installed a Radeon 9800 Pro on MY kt4 uLTRA motherboard.
As noted above, I purchased a new Antec True Power unit, prior to installing for a 2nd time. I am not sure whether that was necessary, but it certainly didn't hurt. The successful installation process was as follows:
1) Download the latest catalyst drivers from ATI
2) Set monitor to lowest possible standard (640 x 480, 16 colours if possible - in my case my digital monitor could not be set lower than 800 x 600)
3) Uninstall drivers for existing video card
4) Replace video card
5) Install ATI drivers
6) restore settings on monitor to maximum.
At that point, after restarting the computer, I had a CLI.exe error. After Googling for this problem, I discovered that I needed to download Net 1.1 from Microsoft. After downloading and installing that additional program, Radeon 9800 Pro is now working perfectly.

Video Artifacts: Radeon 9800 Pro + ACD 23 (Clear) + G5

Hi guys.
I've been experiencing some video artifacts with my retail version Radeon 9800 Pro 256MB (not the OEM "XT" version from Apple) which is driving my ACD 23" (Clear Enclosure), which is connected to a Dualie 2.5GHz G5 running Tiger 10.4.2.
Prior to installing the upgraded video card, I never had this problem, so I am pretty sure it's the card.
It has only happened to me when the G5 wakes from sleep. And it doesn't happen very often, either. Maybe 1 out of 20 wakes from sleep. The only way to get it back to normal is to turn off the G5 completely, disconnect the ADC connector cable from the back of the video card, and then reconnect it and reboot.
I also have a second display connected to a Radeon 7000 via VGA and when the artificats appear, the other display is just fine. The weird thing is that I can actually take a screen shot of the artifacts, which I thought wouldn't show up. I am not sure what that means, but I think the fact that I can take a screenshot of it tells me the display is being corrupted at the system level. Right?
Any help would be appreciated. TIA.
Here's a screenshot:

Hi Bryanus,
Did you have an ADC port on your old card? Do you still have your old card? If this is the case, you can verify that the new card is implicated by re-installing your old card and seeing whether the problem repeats itself.
If you only have DVI on your old card, you would have to borrow an adaptor, but then you are relying on the adaptor to function properly.
If the problem doesn't repeat itself with your old card being used, then the new card is the culprit, in which case I'd ask to have it replaced, or get a refund.
If the problem does repeat itself with the old card, then you might want to consider other possible contributing factors such as the physical state of the monitor connection (dirty or tarnished contacts, bent pins etc.).
If the problem repeats itself with a new (replacement) card, you could add AGP slot issues to the above paragraph.
"Sleep" in an Apple Mac often generates issues with third party hardware, so your primary consideration that it is probably the card is (to me anyway) still the most likely.
All the best with the diagnosis!
Cheers!

S-Video not working on ATI Radeon 9800 Pro????

I've had this ATI Radeon 9800 Pro in my MDD dual 1.25 G4 for a little while with two VGA monitors. I recently got rid of the secondary monitor and moved a 27" flat screen tube TV next to the computer. As I always do, I've got to start tinkering. I remembered that my Radeon has both VGA, DVI, and an S-Video outputs. I simply ran an S-Video from the card to the TV. I can't seem to get it to work. I had never used the ATI control panels so I went ahead and downloaded and installed it. It won't "detect" the TV in the Mac2TV control. What the heck am I doing wrong???? I emailed ATI and they just sent me a form reply to a dead link saying that my system is unstable. UGH!
Any tips would be great.
Thanks much,
Robert

Well, I figured out that if I reboot and only have the s-video attached and no monitors to the VGA or DVI it will work. It dedicates the TV as the primary screen. However, not the best picture. I can't find any information if both the s-video and VGA or DVI can operate at the same time. I'm also doing a little more research with ATI to see if they actually have a true component output from either the VGA or DVI. I had bought a DVI to what I thought was supposed to be component but it was actually RGB component and just gave a distorted image. If I can get that to work, I think it would be a better image along with being able to run both the monitor and the TV as the secondary.

Will the following ATI Radeon 9800 Pro work on a G4 MDD?

I have an ATI Radeon 9800 Pro, 128MB DDR, and I'm wondering if anyone can verify if it will work on a G4 MDD. It was bought for a G5, but that G5 doesn't exist.
Embossed on the front of the card it says:
PN: 109-a14400-01
On the back there are 3 stickers:
1) J53480YRQ74B 603-4070
2) SN + PN: 102A1440103 000009
3) J53480YRQDMA 630-4908
On the metal back-plane it has etched: 805-5422-A
The card has 1 ADC connector with 25V/4A Max written beside it, and one DVI.
Google brings up some hits, but nothing definitive concerning G4 vs G5.
Thanks in advance!

If it looks exactly like this one, including the "teeth" along the bottom, it won't work in any G4.
This card has an "AGP Pro" connector, which gets all of its power through the slot (it has no molex connector).
Even if the card was cut to physically fit in a G4, the AGP slot in a G4 (any model) can not provide enough power for a 9800. It would fry the G4, the card, or both.

Getting two Displays to Work on a Radeon 9800 Pro Mac Special Edition

Hi Folks
I am reallt having difficulties here. Let me explain:
1. I have a Power Mac G5 (2004) Dual 2GHz WITH 2GB Ram (http://support.apple.com/specs/powermac/PowerMac_G5_June2004.html)
1. I have just purchaed two 24" Dell Displays that come with DVI and VGA leads (http://accessories.euro.dell.com/sna/productdetail.aspx?c=uk&l=en&s=bsd&cs=ukbsd t1&sku=59234).
2. I have also purchaed Radeon 9800 Pro Mac Special Edition 256 DDR (http://ati.amd.com/products/radeon9800/radeon9800proseme/specs.html).
3. I want to connect both displays to my 9800. One of them can go into the DVI port, but what do I need to get the other monitor working on the 9800? I presume I will need some kind of adapter?
I have spent literally hours, and hours seaching forums and google to find the answer to this.... just can't find the solution.
If anyone can help I would be indebted.
Thank you so much.

Hey Hatter
Thats great. I have already bought the 9800 so unfortuantly Im committed. I managed to get it for about $200 brand new so I felt that was a reasonable price.
I have pruchased the following adapter - http://www.pcwb.com/catalogue/item/GEFEN068?speedtrapid=froogle&lead=froogle
Thanks so much for the advance....your a star mate!!

Stock Radeon 9800 Pro card from a G5--- Will it work in my G4 Quicksilver?

I am thinking about purchasing a stock Radeon 9800 Pro card that came with certain G5 machines and use it in my G4 Quicksilver 867mhz machine. I heard that this works. Is it true? Can I download the drivers from the ATI website? Are there any issues I should be aware of? Any help is greatly appreciated. Thanks.

Hi-
If it is the OEM 9800 Pro, then it is an 8x AGP, backwards compatible to 4x AGP.
Your QS is 4x AGP, and the card should work.
Drivers are here:

ATI/Radeon 9800 Pro 128 AGP 4x/2x in Gigabit Ethernet dual 450 PMac G4

Hi,
This is my first time posting to these discussion group... I've been going through related threads and have not found an answer to my problem...
I have a Gigabit Ethernet dual 450 G4. Awhile ago I upgraded the processor to a Sonnet 1.8ghz so I could run Leopard.
I just bough the ATI/Radeon 9800 Pro 128 AGP 4x/2x video card. I researched around and that seemed to be a card that would work in my machine. I even read a review on Amazon where someone had also upgraded to the 1.8 processor used this card with no issues.
I do have an older monitor - Apple Studio Display CRT with the ADC connector. So I also bought the Apple DVI to ADC adapter kit.
I installed the card and do not get any picture at all - I believe I have installed everything correctly. I'm pretty sure I can hear the fan on the video card in the machine. The monitor is getting power from the adapter since the button lights up when I press it - but it does not stay lit -- the monitor never turns on. Using my old graphics card the monitor makes a little "beep" when it turns on.
In reading the other topics I am wondering if it might be a power issue? According to Other World Computing's profile my machine has a max of 220 watts. Although they suggest this video card as one the will work in my machine.
I have disabled the hard drive that came with the machine (too small) and am using two Maxtor hard drives that I added - one ATA (120gb) and one SATA (500gb) that is connected to an SATA pci card. I also have two additional pci cards with usb 2.0/firewire ports.
In looking at the topics here I came across the link about taping the 3 and 11 pins on the video card. Even though the card I have is 4x/2x not 8x I thought I'd give it a shot. That did not work either.
Any help you can give would be greatly appreciated.

I don't wish to sound redundant here, but I've been reviewing the vendor's page:
It's OK- I don't mind beating this dead horse....
The maker says such to protect themselves from possible claims that may arise due to over loaded systems and power problems when their card is installed in said system.
Of course, 300w would be nice, but they didn't even specify the PSU rating a couple years ago. The Sawtooth, with it's 237w PSU, used to be listed as a compatible machine for the 9800...... They just didn't consider how far a Sawtooth might be modded.
Within reason, the early G4's (Sawtooths) are capable of using the Radeon 9800 Pro. The GE has the same 338w PSU as the DA (they are interchangeable), so there is plenty of power for the 9800.
One thing to remember, the requirements of the ADC port of the AGP slot are removed by using a non ADC card. This really changes the calculations of the power available.
It's kinda' a long post, but, if you care to get ALL the details, check the following:
http://discussions.apple.com/thread.jspa?messageID=7065653&#7065653
I think you'll be satisfied with the explanation.......
Which leaves your second, and very appropriate, point.
The main enemy of all, though, isn't power. Heat is the biggest concern.
Reducing heat/increasing cooling by using a third party fan on the 9800 is highly recommended. The 9800 is a hot card, and the stock fan is prone to early failure.
Adding additional cooling to remove the extra heat produced by the 9800, by using an exausting PCI fan, will also help the PSU provide adequate voltage to the system, by reducing the amount of hot air moving out of the PSU.
Super heated air moving through the PSU reduces the cooling ability of the PSU. A hot PSU doesn't produce reliable power.
So, add the 9800, add some cooling, and enjoy!

Radeon 9800 Pro (128MB) on G4 with lots of artifacts

Hi there,
I recently bought a radeon 9800 pro (mac version) over ebay. I put it into a d1ghz (quicksilver with 1.5GB of Ram. Everything seems to work fine, however, the screen flickers ever so slightly after the ripple effect in the dashboard. Yet this is not really what bugs me: Any game (and probably other applications as well) which uses Core Image produces huge artifacts. There are just random screen-filling bits sticking out the ground...
How do I get rid of this? I already checked all the connections, ran software update, downloaded the most recent drivers and tried downclocking the graphics card.... (I also think that I cleared NV- and PRAM, but I am not sure... )
What am I forgetting?
Thanks already, dl33

Hi. I had the same problem, but it was a 500 mhz Sawtooth. I was told it was either a power issue or a heat issue. So I upgraded the power supply from 237 watts to 400 watts. It seemed to help, but it started doing the same thing. After wasting a lot of time and money with power supplies and soldering and adding fans, etc, I looked at the fan on the card. Like you, I bought mine used. The guy said it worked flawlessly. When I first got it and experienced the problems, I checked the fan. It wasn't the stock fan, was a unit from Arctic Cooling. The fan was spinning, but it said that air should be blown out the exhaust, and I felt none. Upon closer inspection it turned out that the fan was defective. It was constantly speeding up/slowing down, and it was supposed to be a single speed fan...not good. But by the time I figured that out, the card had been fried. I got a new unit from Arctic Cooling, but the card no longer works.
Might want to check the fan and make sure it's spinning. Your power supply should be sufficient since I believe the QS's had 344 watt PSU's.
One thing I forgot to mention was that underclocking it usually helped. I had to underclock it a good amount, though. I believe it was around 20%.
Hope this helps.

ATI radeon 9800 pro (256MB)-- Apple 23" HD

ive had this graphics card for a good couple of months, about 6 or so to be exact, a card given to me by a friend who just didnt need it anymore, upgraded to something or other.
now, the issue is that two days ago, it just stopped working. i tried to turn on my comp and it turned on as usual, but the monitor did not. i thought it was the adc to dvi adapter that i bought to use this type of graphics card for such a screen. but it reconnected everything and still nothing. i then finally got my old graphics card, yes i still had it =D, and i tried turning it on with the adapter still connected, simply swapped cards, and the monitor worked. since then ive tried reconnecting because i wanted to make sure the wires are ok but no luck with the radeon 9800 pro (256MB). anyone have any clues what i can do? it doesnt have warranty due to it being somewhat old, friend had it for a while.
annyone have different ways to connect this card? maybe i can try a different method? is there a place i can take this card, to see if it is indeed something wrong with the card and not something with my computer itself acting weird to it? oh and btw i have a powermac G4 (MDD) 1 gig or ram.

Hi,
The card symptoms do indeed sound like it's malfunctioning. If re-seating the card doesn't help, the aux. power is plugged in and the fan is running - that's about it.
Malcolm is right (as usual) about that card only being available for less than 6 months. In addition, it has a 3-year limited warranty from ATI. If it is the 128MB model, it still may be under warranty. I would persue that angle, for sure. ATI info
BTW, what G4 are you running? That would help us in answering further questions.

Dave

Radeon 9800 Pro--Broken?

I just bought a used dual 1.42mHz G4 tower and put an AGP 128 MB Radeon 9800 Pro in it; it doesn't work. I can't reset the PRAM with that card in there, and so the machine just sits there. Is it possible I need a driver that didn't come with the Leopard install?
I ask because this card worked Ok in my dual 800mHz G4 tower, but that machine died. I had removed the heatsink from the 9800 when I installed an Iceberq cooling fan last summer. Although the card did work for a while, after that, I might have partly damaged it. The AGP slot in this 1.42 machine is on the opposite end of the PCI row, so it's not possible to use the Iceberq. After removing it from the 9800, I had to find a heat sink to put on the card, I wound up using four small copper heatsinks, but between the crazy glue, and all the handling, I figure I won't know for sure if the card is the problem until I ask about this here. The 1.42mHz machine is a bit different than the earlier G4 towers, so it's worth a shot..
Anyone?
Thanks, Greg Reyna

Someone in an electronics shop suggested mixing thermal compound with crazy glue, which is what I did. Nothing else was working, and anyway I felt I was screwed. (self-screwed, that is). You see, I took the fan/heatsink off the 9800 when I got the Iceberq. That was fine for the computer it was in, but as I wrote above, the arrangement of AGP and PCI slots arereversedin this computer. You know, if, when the 9800 is installed, the chip(s) are on the right side of the card, and there are no PCI slots on that side of the AGP slot, there's no way to use the Iceberq. The way this box is designed, the heatsink on the AGP graphics card hangs over the RAM slots. And in addition to that, when the door is closed on this computer, whatever card is in the AGP slot has to slide neatly over the top of the CD/SuperDrive housing. If the heatsink, or fan, or whathaveyou on that card is more than 15 mm high or so, it doesn't fit--the case won't close. So in other words, once I "customized" the 9800 for one computer, it was pretty much useless in the other computer. I'm not sure the 9800 with its original heatsink/fan would have fit the door closing. So I rigged the 9800 with these four small copper heatsinks just to see if it would work--it didn't. If it had maybe I could have installed an arctic mole to blow on it and keep it cool, I don't know, it never came to that. Meanwhile, I'm back with the 64MB graphics card that came with this used machine, and it's running well.

Radeon 9800 pro 256mb hanging on blue screen

I'm deep in the waters of frustration right now, and am hoping someone here might have the answer.
About 3 months ago I was looking for a video card for me to run motion. I saw the 9800 mac special edition with 128mb video ram had rave reviews. At that time ATI was not making them. So I turned to eBay...
I purchased a card that was advertised as a Mac 9800 pro special editing 128mb. I later found out it was a flashed pc card. The ebay seller told me the card worked fine on all his mac's that he tested it on.
The problem I was having was the machine boots up, I see the grey screen with the Apple logo and spinning wheel. I see the blue screen where normally I see the login progress bar loading the OS. But with this card I only see the blue screen. I hear the hard drive churning, so I am assuming it is still loading the OS, but I cannot see anything. I can reboot in safe mode and the video card works fine.
Well... I assumed it was the fault of the card and that it was flashed. I returned the card to the ebay seller, who sent me another one, same results with that one. I returned the card to the seller and he refunded my money.
I put the money toward the just released Radeon 9800 Pro Mac Edition 256mb card. I just got it a couple days ago and am experiencing the same problems. I have tried everything... everything I know and still can't get the card to work? Here is a list of what I have done:
With the flashed card:
1. Shut off computer and unplugged it. Removed OEM video card and installed ATI 9800 card. Plugged the power supply cable for the card into the computer power supply cable and hard drive.
Problem Occurs: When starting up, the grey screen comes up with the Apple on it, then the screen turns blue, where I typically would see the progress bar of the system loaded up before the user login screen. I only see a blue screen at this point but can hear the hard drive working for about a min.
2. Restarted the computer in safe mode.
3. Logged in as Admin user and opened the ATI preference pane to verify it sees the card.
When the ATI preference pane was loaded the following error message occured:
A startup problem has occured.
Cannot connect to ATI TVOut Kernal Extension. Some features are not available.
Clicked OK and the ATI preference pane appears.
4. Close the preference pane and reinstalled ATI Displays 4.5.6. Restarted computer.
Problem Occurs
5. Restarted computer holding down AppleOption+PR to clear PRAM. Cleared the PRAM 4 times in a row, by allowing the chime to happen 4 times.
Problem Occurs
6. Shut computer down. Disconnected the DVI plug for the cinema display and connected a VGA CRT monitor. Started computer.
Problem Occurs
7. Shut computer down, disconnected the VGA CRT monitor. Reconnected DVI plug and restarted computer.
Problem Occurs
8. Started the computer in safe mode. Logged into admin account. Opened the ATI Preference pane.
When the ATI preference pane was loaded the following error message occured:
A startup problem has occured.
Cannot connect to ATI TVOut Kernal Extension. Some features are not available.
Closed preference pane.
Went to ATI site and downloaded:
aug2005-radeo-universal-rom-update.dmg
Ran the updater.
Restarted computer.
Problem Occurs.
9. Restarted the computer in safe mode. Changed the login preference pannel to automatically log into the administrator account. Restarted computer, waited for the blue screen, then walked away for about 2 hours with the computer on blue screen, hoping the system was loading or doing something.
Problem Occurs.
10. Put in the TechTools Pro CD, hoping to run some tests on the video card from the cd. When booting from the CD OS...
Problem Occurs.
11. Enabled Root user. Logged in as root and installed ATI Displays 4.5.6 from there. Restarted computer.
Problem Occurs.
12. Shut down computer and installed old video card.
13. On an internal hard drive in the computer. Wiped the drive and formatted it. Installed 10.4.1 on the drive. booted up into the drive, installed ATI drivers, shut down computer, installed 9800 pro video card, booted up.

Help?

I get dizzy just thinking about it.
I have tried installed a brand new OS, 3 different times on a different Hard Drive, still the card doesn't work.
I had one person suggest that it may be the card is not communicating with the OS Window Drawing module? (excuse my ignorance of what that is really called. I just know there is some program, possibly in the kernel, that is responsible for drawing out the OS windows.)
How can we rule out that it is a bad AGP slot?
•The slot works fine with my 9000.
•It works in safe mode with the 9800.

Here is a link to a complete list of everything I have tried:
