| 1105670 | 2010-06-01 07:28:00 | I am staying with my son in Sydney and the fan on his 9800GT vid card is not spinning (no voltage). It does go very occasionally so the fan is OK when it has 12V on it but the card is just not feeding it the volts the vast majority of the time. Tried googling but no answers that I could see. Hampered by no tools (bought a DSE multimeter!) so wondering if anyone has any useful ideas with this. Do you think it is just a duff card?? ATM I am considering direct wiring of the fan to a 12V molex PSU connector. (Soldering iron would be handy!). FWIW it is a Dell Dimension 5130 XP SP3. Card has been working for about a year. Installed latest NVIDIA drivers. TIA. |

| 1105672 | 2010-06-01 12:24:00 | You sure you're using the latest drivers?? Because one of the versions (196.75) did just that. Stopped the fan | Speedy Gonzales (78) | ||

Stopped the fan Is the cable from the fan onto the graphics board properly seated? Also testing the fan with a 12V power source would rule out a broken fan. You could try downloading a program like EVGA Precision which gives you fan control, and try setting it to 100% fan speed or similar. |

| 1105675 | 2010-06-02 23:50:00 | Sorry for the delay in getting back . The fan runs fine fed from the PC PSU . No noise from bearings etc . Plug to header fine . The card just switches the 12V off . Used the latest 197 . 45 dvrs . I have just updated this comp to W7 and it is now using the W7 supplied dvrs . Plugged the fan back onto the vid card, fan spun for 5 sec and then stopped! The fan 'controllers' like evga precision think the fan is spinning fine so they have no control whatsoever . Just looks like the vid card voltage control is very flaky . Better get this shutdown and hook the fan back to the PSU molex . At least this way I know that the chip is keeping cool (46 deg) . Thanks for the help, guys . |

| 1105676 | 2010-06-03 03:46:00 | But it's probably already caused damage. It's an ancient card now anyway, why not just replace it with something else cheap. | pctek (84) | ||
| 1105677 | 2010-06-03 05:16:00 | Unless it actually starts artifacting etc I wouldn't write it off. Cheaper to get a molex to fan adaptor if it's still working. | Agent_24 (57) | ||
