I need replacement..

If you need a replacement part then I highly suggest you try to contact Razer’s online support to see if you can purchase a replacement. Other than that, an alternative would be to look on eBay, although from a quick glance all I can see are 2016 and 2014 fans. If it turns out to be impossible to find a 2012 fan, then it might be worth trying one of the latter model fan replacements, but it would be a bit of a stretch.
