Hi,

Recently, the fan of CPU make more sound, I have shaked dust from the fan. But it still make sound.
Can I use oil for it? And where?

Sometimes this works, sometimes it doesn't: Contact Cleaner lubricant Spray (google it).

You need to take out the fan (and heatsink if it's a combo unit) out of your computer, and spray the fan motor to get all the crud out. I recommend wearing safety goggles when doing this.

Like I said, sometimes it quiets up the fan, sometimes it just makes the fan die sooner. But it's a rather inexpensive experiment, because if the fan is getting noisy, it's on it's way out anyway.
