DJSCAN 250 adj help

I just bought a couple more djscan 250s, and on one of them the fan still works but it is very weak. When I black out all my other Djscan250s they cool down in about 10 min. but even after 20 min, this one light will still be hot . Is there a replacement fan i could order from you guys?? Or do i even need to replace the fan, (I dont really know if the light would last a whole gig, i only tested it for about 20 min...)

Also, i heard from a couple people that the djscan250s are being discontinued? is this true?

ADJ let me know if i can order a fan or if i have to send the unit back to you guys..
Any other advice would be usefull too
thanks
