Right... i was there and i know there are going to be loads more people out there wanting to know how to remove the blades from the fans so they can change it with paint or leds etc...
this guide will tell you how to dissasemble them and reasemble them.
things you will need:
2 very small flat screew drivers.
clean or dirty coffee cup - your choice
Complete picture list
first of all take the fans and place the back facing towards you.
now remove the sticker
one the sticker is removed, remove the little rubber or plastic cap behind the fan. - you will need one of the smalle screw drivers for this
once the cap is removed it will look something like this.
now take the 2 small screew drivers and remove the small plastic clip. - please note is is very soft and can break easily.
now with the clip removed it will look like this.
turn fan around, and pull fan off.
now that the fans have been you can do what ever you want.
i would advise that if you are going to paint the frame tape up the centre part so no paint and chemicals get on to it.
once painted or doing what ever you needed to do , just do everything in revers.
now you will need to assemble the fan. put the fan back into place.
one in place turn the fan over and place in on your dirty cup from your coffee and then place the plastic clip back into place. - not the cup or glass needs to be smaller than the fan housing. , so you are pressing on the fan blads.
once that is done place the plastic cap back on to the fan.
you can, if you want to replace the sticker back to hold the cap in place. it is advised so the cap will not go missing.
then you are done.
