Hello guys. I have a problem with a PNY XLR8 GAMING RTX3090 graphics card. The problem is that it displays and works fine, but the fans don't spin at all. The problem occurred when someone else removed the fans in order to clean it and broke one of the fan connectors. He replaced it himself and after that, it wasn't working anymore. I guess he damaged something else in the process. What i have done so far: I found 2 capacitors next to the connector that were in a bad shape, he must have touched them with his tools - they weren't shorted, but i replaced them with similar ones from a similar card. No change. I tested the fans, separately, injecting voltage - they spin fine. I plugged in another fan from another card - it doesn't work. There are 2 connectors on the card and 2 of the fans are on one of them and the other fan is on the other connector. None of the fans spin. I measured voltages as follows: First - Without any fans plugged in and the card switched on with the computer switched on (displaying picture just fine) : PIN1 : 3,3V , PIN2: 1,8V, PIN3: 12V, PIN4 is ground. Second - With just one or both fans plugged and everything switched on, displaying picture just fine: PIN1 : 2,3V-3,3V fluctuating, PIN2 and PIN3: 0,6V-2V fluctuating, PIN4 is ground. If you check the fans speed on the computer it is saying that they are turning with 90%, then 95%, 97% etc... even though, they don't move at all. So i guess there is something wrong with the driver of those fans or something else but i don't know where to look for anymore and i can't find a schematic for this particular model. I have found for other RTX3090 but on them, i don't see the fan connectors and the design seems to be different. Does anyone have any ideas where i can look for the problem? I have uploaded pictures, the broken connector is the one on the left, upper side. Thanks a lot.
