can that fan be open up?? it looks like all sealed? any pic of a fan being open?
anyway, i bought some tools in a DIY shop just now:
- motor oil, a few drops make the fan revive
- 1 set of RM6.5 multi screwdriever which help me to unleashed the 4pin ATX at last!!!
with this set of screw driver, I think I can open any molex, 4/6/20 pin ATX

- also managed to get 1 meter of black only colour heatshrink from an electronic shop.
any idea if I need to plug this (6 pin Auxiliary power connector) somewhere on my Intel mobo? I had forgot to label this one.
I read somewhere and it says:
"The aux power cable was added to provide extra wattage to motherboards for 3.3 and 5 volts. This connector is rarely used. It occasionally shows up on older dual CPU AMD motherboards"
