OLVINS Left and Right Side CPU Cooling Fan Compatible for MacBook Pro 15" A1286 (Left+Right) Year 2008-2012

Received the fans today and swapped them out (old ones had become warn). They work but, produce a loud whirring noise starting at around 3500 rpm. Will wait until seller gets back to me, but I am considering returning them.

Works nice but too much noisy.

I purchased these for my late 2008 MacBook Pro A1286. I initially noticed the fans were heavier than the original, and when I installed them and powered the laptop, they were noisy, making an annoying scraping sound (both of them). I removed them and returned the item. I believe the item was not genuine as I bought another set soon after, which were lighter and made no noise.
