I have a good old Lenovo Essential B570, which has been working perfectly for the last 6 years. Sometime back, I had a fan replacement, which worked fine but I was fed up of the noise it created. So I ordered a new Lenovo B570 fan myself from China.
When I opened the laptop to install it, I was surprised the fan fitted to the laptop was different from what I received. Here are the pictures of both. (left= new one, right=old one)
What I dont understand is what's the portion marked yellow? Is it very critical because I could not make it stick to the motherboard due to screws issue. I thought if old fan without this worked quite long, it should not create any problems.
looking forward to your comments

I'd also appreciate if someone can tell me what's the name of these items marked in yellow circles. They were missing and I could not fix the fan properly because of it.
