Did you know this? I sure did not.
Just got in a Dell Dimension 9150 to setup and test.
I had to reinstall everything ( for lab reasons ), and after deleting all the partitions, I started reinstalling XP from the Dell cd. I noticed that the video card ... 7900GS 256 .. was making a lot of fan noise. It was so loud that I called Dell Tech Support about it. They did not know why either, and started to send me a replacement. In the meantime, I downloaded all the drivers from Dell, and as soon as I loaded the video driver for the 7900GS, the fan went quiet, and now runs under the control of the driver. If I really push the 7900 in a 3d app or game, I can hear the fan come up somewhat, and I can see the temp at about 50C. After a while the fan quietens as the temp cools. My question: is this true of the standard 7900 driver for all machines. I have the 7900 GTO at home, and I had to install a better fan with an external controller to quieten the thing. My home card runs at 33C to max of about 48C with that fan. Be nice to put that fan under the driver control since it also has speed control on the card ??? The Dell driver works fine. Shame the 7900GS has such a crappy OEM heat sink. It deserves better .. but mine cost me about $55. johns |

Yes, this is normal behavior with new nVidia cards. In the old days (FX5800
era), they just had two distinct fan speeds for 2D and 3D. Now it ramps up progressively according to temperature. With Rivatuner you can adjust several parameters like the idle fan speed, ramp schedule, etc. The ramping action requires the fan controller to be capable of sending a PWM signal. Not all cards can do this, obviously. Furthermore, some cards have the hardware, but the BIOS doesn't expose it to the drivers. Which category your GTO belongs to is anybody's guess. -- "War is the continuation of politics by other means.

category your GTO belongs to is anybody's guess. I wish they'd stop it with the guessing games. This driver control of cooling and keeping the thing quiet is the difference between buying the card, and not buying the card. An uncontrolled 7900 is a nightmare, and yet this is one of the top cards out there. I even called BFG on my BFG 7900 GTO, and the tech guy basically laughed in my face, and dared me to void my warranty by installing a quiet fan. Now, I learn that the proper driver for the thing does a nice job of quieting it down. You'd think that BFG tech support would know that. They don't. I'm glad I have my Zalmon cooler, but maybe I could have just downloaded a decent driver for free. The other thing is, if BFG is building cards that are not very smart, then maybe it is time for them to "smarten" up. Also, I have yet to see these Dell Dimensions fail to do their job, and respond to any challenge I have set them against. Somebody over there is getting the job done. johns |

Now, I learn that the proper driver for the thing does a nice job of quieting it down. You'd think that BFG tech support would know that. Before you start crapping over the tech support guy... If the fan wasn't quiet before, what "improper" drivers were you using? The first step of any troubleshooting process is ensuring you have the most recent drivers installed. They don't. I'm glad I have my Zalmon cooler, but maybe I could have just downloaded a decent driver for free. It's not quite that simple is it? Does a loud fan suddenly become acceptable in the middle of a game? There's no substitute for a fan that remains quiet at 100% speed. The Zalman definitely was not money wasted. The other thing is, if BFG is building cards that are not very smart, then maybe it is time for them to "smarten" up. Again, keep things in perspective. http://enthusiast.hardocp.com/articl...hlbnRodXNpYXN0 Keep in mind the BFG card is overclocked out of the factory. Naturally it won't run as quiet as the Dell card. BFG is the only mfr not getting an unusually high number of returns from cards overheating (versus eVGA, XFX, etc.). The company is at the top of its game. -- "War is the continuation of politics by other means. It can therefore be said that politics is war without bloodshed while war is politics with bloodshed." |
