Problem now is I can't get it off, it looks like it is press fitted onto 2 plastic nubs and it won't come off despite some effort, I'm afraid ill break it if I put any more pressure on it. Is there a trick to getting it to pop off?

I'll check it out tonight, thanks.

It does not seem to be the one on the hot end, is there another internal fan and how do you access it?
