New video card fan not turning on.

After a month of owning my geforce gt 620 i just realized the fan isnt working. the card was a pain to get in my tiny dell optiplex 755 in the first place. so i took out the harddrive to get to the video card and shaved off a bit of plastic so i wouldn't have to take out the hard drive again. before putting in the hard drive i noticed that the card will not slide completely down because of two cylindrical nodes on the motherboard hitting the heat sink. i bent the heatsink to get a few more millimeters of space. could this be the reason for my fan not working? would i be able to wiggle these nodes to the side a bit? the card is slanted as you can see. Also, according to gpu-z my fan is running at 35%.

  1. Hello, Quigonjim
    Do not bend the cylindrical nodes. I also doubt that bending the heatsink could prevent the fan from working unless it is touching the fan. Is there a connector that could be disconnected on the graphics card? Hope I helped

    thanks for the reply :) anyway, yes, there is a connector. could it be that im using a 300 watt card on a 275 watt supply unit?

    It could be the power supply bot being able to deliver enough power. But I took out my GT 610 and there was a small fan connector. Hope this helps (I think a psu not delivering enough power causes blue screens but GTX Titans can run on 500 watts from what I've heard)
