HK-part Fan Replacement for MSI GS63VR

My CPU fan died about 2 weeks ago, so I decided to buy these as replacements. I brought my laptop (GS63vr Stealth) to my local bestbuy (where I originally baught the laptop from) and had geeksquad install these new ones. Don't get me wrong, they work, but they are much worse than the originals. They don't go as fast as the originals and my Laptop has had much higher temps and lost frams ever since I have had these fans installed. Even when I go on dragon center and turbo the fans to max speed, I can bearly hit 3000 RPM when the originals would hit double that speed. Also, in the product info, it says the fans would arrive with thermal paste, but I got the fans in a crappy plastic shroud, with no thermal paste whatsoever. It's a shame that my almost 2 years Laptop can't preform like it used to, just because of these crappy fans that are listed, and MSI won't even provide a link to buy the Orignal replacement fans. Unprofessional experience overall.
