Removing Chipset Fan please help

[Egosh]

Hi,

My chipset fan is about to die on me so i decided to get a new one. Anyway got the new on today but i cant seem to take out the stock fan. Ive got a asus a8n-sli deluxe mobo so if anyone know how to remove please let me know. There are two push pings on the side and no matter how much i pulled they wouldn't come out.

Thanks for the help

ok well the idea of taking out my mobo isnt too appealing to me..so another idea not sure would work but..i cut the top off of the pushpin and just push it through the mobo so it falls out from the other side...it sounds like a good idea but what do you guys think?
