    Im pretty sure that won't do anything. You should instead get an actual cooler. and 57-60c isn't even that high.

    A better idea would be leaving your case door open while you game if not already opened.

    I used to have a 120mm fan proped at the back of the gpu and it kept the surface cool to the touch. I dont think that tiny fan is going to do a darn thing imo ;)

    wont make any difference. it may fool the temp sensor on the PCB if there is one present.

    hang a 120mm fan on the back side of the ODD bays and let it cool the entire card, or add a fan to the door of your case to blow right in at the side of the card.

    Not a bad idea at all. Might as well try it. I'm sure it will lower you GPU temps a little.

    Don't suppose its any different from the 80mm fan mount available on my CM 690II that blows cool air on the backside of the CPU socket. Don't expect large drops, but it surely wont hurt.

    Hi! I'm from the Internet
    I have 2 4870's in crossfire. A Asus Dark knight and the other is the same card you have. Mine isn't oced and my fan is set at 65% and the temps are running the same as yours. So with your's being oced I think your temps are great.

    it aint help the temp much
    first the fan is small second the gap between the fan and the pcb too close so the airflow wont circulate nicely

    PCBs are the other part that dissipates heat, they dont do the best job but they still do. How are you going to mount a fan on the back of the card? and Also another note the smaller the fan the faster it has to rotate to push air, thus louder. Other issue is spacing so you dont wreck any SMDs or solder joints on the card

    You can mount a 120mm fan of your choice in 3x empty 5.25 bays by using strips of foam, like the kind that comes with your GPU box. Then just get some mesh bay covers and good to go, or leave them off entirely..
