    Hi

    I'm going to make DIY cooler and I want to inastal 3 fans

    -Ball Bearing
    -12*12CM
    -rpm>1500
    -CFM>30

    I want to instal the fan like a horizontal T,Two fan in the left side , because the GPU is there, I mean:

    *
    ***
    *
    -Does 90 CFM can cause any problem for laptop fan and disturb its moving?
    -Should they blow the air into the bottom or suck the air from the bottom?
    -Which one can cool the 1530 better and cause less disturbance for its internal fan?
    -Should all the fan suck or blow, as same as each other?

    Please talk Scientifically!

    Thanks

    You will want this to help move air with the fan. So if the fan draws air in from the table, you will want the cooler to blow air up.

    As we all know, hot air rises up. :D
    You should build something like this.
    Its all right from the back.
    I suggest, you want the cold air to get into the middle and the fan from the bottom.

    hope it helps

    One fan should suffice, since it is a custom cooler. All the magic happens at the heat-exchanger, that is the most important thing to remember. You will get some passive cooling by blowing air at various spots, but really, the copper does a much better job at taking heat away from the components, so you should focus all your efforts on the heat-exchanger area. Get as much air flowing through those vanes and you will see a much bigger effect than just by blowing air randomly through each vent on the bottom of the laptop.

    Of course, if you push so much air through the fan that it increases the speed of it, by too much, there is definitely a possiblity that it could damage the motor. But I think you would have to be going VERY fast.

    Also, the vane geometry will have been specially designed for a particular operating range, if you go make the fan spin too fast, you can create turbulence, or basically 'stall' the cooling efforts.

    It's an interesting project, and you could post about it a lot and think of lots of different ideas. But best of luck anyway, have fun. Maybe by a spare fan/heatsink just in case!
