these guys are awesome. Here's their response regarding the fans:
"Normally, the fans in the lamp should not produce such a noise, it must be something blocking the fans from inside. You could open the cover (by take out the screws) and check out what’s the problem.
But anyway, the lamp you got must be the old version, we have changed all the fans to a better and more quite model. Please give us your address, we will send you the new fans for free, so that you can change them.
Sorry about it."
