Lenovo B570 Fan Question

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

Re: Lenovo B570 Fan Question

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.
