On the subject of the clips for the 120-X, am I the only one having problems with them?

I've poked them into the small holes at the middle of the sides of the sink but something's not right. Whilst at the top of the sink they clip into the fan holes firmly, at the bottom they don't go in at all securely and the slightest pressure with a finger will dislodge them from the fan holes. It's as if the little bit of wire that goes into the hole in the sink isn't moving about freely and is in turn applying some "outward" pressure on the wire, trying to move it out of the fan hole.

Having real trouble explaining this as you can probably tell - noone else I've tried explaining it to knows what on earth I'm on about.

I've had to resort to using cable ties to secure the fan clips to the fan itself which is hardly ideal. What am I doing wrong?
