BB2 Lower Monitor replacement fan

[stlscott]

I have a "loud hum" coming from the lower Monitoring on a BB2E.  I'd like to order a replacement one so when I pull it all apart, I can just replace it.  Yes, I know I can take it apart to find out, but was trying to get the fan ordered (will order several) ahead of time.    Does anyone know the specs on the internal monitor fan on the lower (touch screen) on the BB2E? 

If someone has pulled this fan already, please share the specs (20mm x 20mm x 5mm 12v - for example?? - that's just a guess).  Is there a fan in the top monitor and if so, what are it's specs?

I've already replaced the two cabinet fans, the CPU FAN, and the Brainbox Fan.

Thanks.

For anyone who would like the info before having to take everything apart themselves, it's a standard 80mm x 80mm 12v FAN, same as ones often used in computer cases.  16 Screws + the 4 screws on the VGA/DVI connectors gets the back off,  to find the fan bolted to the back of the case from inside.
