flora, 好丫!  我即刻去廁所睇睇有冇!!

there is no special cleaning kit.  Even you can clean the dust....the bearing in the fan still jam.  Then it will cause the fan move slow, or create sound....Then you have to change the fan.

但依家把 fan 無 sound 喇喎.....但 in case 我係咪應該買定多一把????

走人了......... 返到家再談!  

你去邊個廁所睇啊????

depends on you la.

但無人幫我換啊~~~

You can't do it yourself?  I think there should have instruction in the new fan box.  Just give it a try.

buy one from futureshop, open the box, if you don't know how to install it even you read the instruction, return it! or you can bring it to a chinese computer place (gong wing near 63 ave and 104), i don't think they will charge you a lot for changing the fan

我係唔知點拆個舊既落黎......
