VivoBook Pro 14X OLED (N7400PC) - Chassis Torx Screw Size

Star I

Recently, whenever I started my laptop, the fans made a lot of noise and the keyboard deck was heated even if there wasn't any demanding task running.

Yesterday, a rather concerning noise started coming out as if the fans are colliding with something (like a small wire). Can't say until I open it, could be dust.

My warranty ended 3 months ago unfortunately and there doesn't seem to be any way of extending that. 

I was going to purchase a torx screwdriver for this very purpose but don't know which size it is.

Can anyone help me out with this?

I checked the laptop manual but there doesn't seem to be any info whatsoever regarding this.
