FWIW the part Sun sent me as a replacement is completely different from the original part, despite both parts having the same part numbers. The part number is 540-2761-01 on both.

The failed part was a seven-blade Inaba-Denki-Sangyo (Japan) and the replacement part is a eleven-bladed Shicoh (China). The replacement fan seems to be spinning slower and moving less air. As a result it is much more quiet.

I didn't expect them to replace the entire motherboard - I'm more than happy that they replaced the faulty fan :-)
