That seems a little strange, most fans do not run at 100% all the time. Did you uninstall the previous video drivers and install the latest from the Nvidia site when you fitted the card?
i am wondering why its so loud after installing the 9500gt...
because it usually isnt this loud and there are certain issues that im having that i didnt have before..
like video issues, i cant even play a basic game like counter strike 1.6.. i dont really want to play.. i just wanted to test it out.. but it crashes and i cant play.. i mainly make music and i want a stable system.. its becoming kind of unstable when loading up plugins and what not..
Sounds like possible driver gremlins.
Try this:
Download the latest drivers from the Nvidia site, do not install yet.
Download and install Driver Sweeper.
Uninstall all existing video drivers and reboot into Safe Mode. While rebooting, enter the BIOS setup and make sure the onboard video is deactivated (if there is any on your MB!).
In Safe Mode, run Driver Sweeper to remove all traces of the previous drivers. CAUTION! Examine every entry it is going to delete, and make sure it is not going to remove any system files.
Reboot and install the downloaded drivers.
Any help?
the fan on the video card is most likely a generic non reference design - noisy and without pwm or any control over the speed etc - make sure the noise is actually from the PSU and not the videocard
some high end cards may put extra load onto the PSU and generate more heat translating into more noise from the cooling but from a card powered by just the PCIe slot and no extra power so i doubt it is that
you may also have a faulty psu fan (or any other fan) that only started making noises since you worked on your pc because you moved it etc - another common thing
