Arctic Cooling Freezer 64 Pro - leaking?

[Commers]

Just installed one of these, been running it for the last three days on an Opteron 146. Impressed with the performance but it seems to have sprung some sort of leak, I could see droplets of liquid thrown out by the fan on the side window of my Lian Li case.

Thought it was coolant from the heatpipes at first but, on closer inspection, it seems to be coming from the fan bearing so I reckon it's oil.

Anyone else using this cooler had a similar experience?

I've since removed the Pro 64 and replaced it with the stock heatsink (obviously stepping down the Opteron to stock speed and voltage). There were a few drops of the 'oil' on the mobo as well. Hopefully it won't have done any harm.

I've requested an RMA from OcUK.
