Where to buy a replacement fan for an NEC LT150

[rberner]

I have an NEC LT150 and need to replace the fan directly behind the bulb (the bigger of the two). NEC support wouldn't give me the part number and said I had to talk to a service rep. The service reps want to charge me $150 for this.

Do anyone know what the specs are for this fan and/or where I can buy it?

Thanks,

Rich
