    Is there any way to speed up the cpu fan? the fan has a 5pin plug and runs really slow. this case is small and has 1 cpu fan that is a rear fan with shroud over the cpu heat sink. no other places to install a fan and of couse 1 fan in the PSU, an 80cm i think. the hdd is vertical block off the fromnt of the case and its a sata which runs very hot. the cpu is a P4 530 which is also hot and with a pci16ex gfx card i can basically cook eggs on this thing. I would like to get the rear fan cranked up a bit to move some air through this thing.

    ok tried pulling the blue wire out which leaves the wh/bk/red wire, runs fan at top speed sounds like a hair dryer, keep it cool but is way too loud.
    those idiots at Dell once again screw you and use a propritary 5 pin connector which nobody uses otherwise i would have to cut and slice wires together, if it was my pc i would get out the hole saw and mount an 80cm in the side panel.
    I just know this thing is going to fry and be back on my bench in a week.

    anybody know if a dell dim4700 mb is a std atx or micro atx form, it looks like it might be, I would suggest the owner get a better case with more fan mounts but i would have to be able to mount a std 775 fan on the mb and of course have it fit the case mounts. I hate Dell with a passion.

    ok, tossed the green shroud thing and mounted the cpu fan to the heat sink more like a normal pc similar to this idea

    that way mb is still controlling the fan speed, then mounted a 80mm rear fan in the dell bracket, other than cutting a hole in the side or maybe installing a psu with a 120cm fan over the cpu now that the shroud is gone it would work also. again I hate dell they put a prescot core cpu in a little box with no holes, this is the first pc I have seen that is actually warm to the touch on the outside of the case, and warmer than hell on the inside, hope this thing holds up.
