Hi!

I got another graphics card to my collection, this time it is reference Nvidia GeForce FX5900 Ultra.
The problem is that the fan on the card isn't spinning.
After installing drivers in Windows 98 I'm getting message from Nvidia System Sentinel that it is running at limited power.
The fan can be turned on through Rivatuner, other than that, it is not spinning.
I've tried different VGA BIOS but still it is acting the same.

I have another graphics card which is Nvidia GeForce FX5950 Ultra and it is working fine in the same system and with the same drivers.

I presume there's problem with the elements on the board it self...

Can anyone help me?

post hi-res pics of the card. Kinda sound like the voltage reg that is in-line with the molex connector is bad. Could also be something as simple as a fuse or diode.. or maybe something got knocked off the board.

I noticed the solder joints power connector was replaced with different one, not the right angle type, (4 pin power connector drive style) also, said connector was replaced has solder joints on the video card is very sketchy. Also make sure the orientation of the connector's voltages are correct: 5V for 5V and 12V for 12V, by comparing to other connector of like video card.

Have someone with good soldering station and really resolder them with flux and some more solder.

Cheers,

Exactly what I was thinking as I looked through the pics.

This is my own work, I thought it was worth to resolder some of them, it helped with my other graphics cards in the past.

Hi,

Yes still need to heat the solder, adding little solder to get going and bit of flux, waiting for the solder to melt completely and fuse into one homogeneous solder.

Any other ideas?
Is the Nvidia System Sentinel buid in the mai chip or is it elseware on the board? How does it work?

Hey, have you ever been able to fix that? I've got a 5950ultra, which exhibits the same issues. It never did that before. But I changed the PC for it and I actually believe that might be the new PSU (too modern, or too cheap, I don't know - it's Thermaltake 500w RGB).

But unfortunately, I can't test it with anything other currently and there's not a lot about this issue on the Internet (apart the obious did you plug the molex connector properly). The molex connector itself seems to be fine, I checked everything for continuity.

The symptoms are rather similar. My card also sometimes doesn't start the fan. I think it's some sort of low-power safe mode or something. What's interesting is that if I bend PCB just a tiny little bit upwards before it POSTs, I then get the fan to spin and it boots to the system fine without any warnings. However, as soon as any 3D load is started I'm instantly getting the same Nvidia driver message.
