cd backups humms a lot

[sLANE147]

I'm using a Lite-on 48125s which I bought last saturday so its pretty new. I've tried to burn as low as 8 speed but the drive is still making a noticable humming sound.

Is the ps2 making more noise playing cd backups than dvd backups? I havent played a lot of cd backups and the first ones I got were backed up by someone else and these dont make that humming sound.
