Review on 😎 QUETTERLEE New CPU Cooling Fan for ACER A515 A515-43 A515-51 A515-44-R93G A515-54 A515-41 A515-44-R41B A515-55-56VK A515-54-51DJ A515-43-R19L AN515-51-55WL AN515-51 AN515-52 AN515-41 Series - High Performance Fan by John Kachinosky

Wow! I am impressed! Installation took about 20 minutes (I'm also a computer engineer). The fans come with a small screwdriver and a special tool to separate things without damaging them. I didn't need any of these tools but in case you need them. Fans work amazing! They are so quiet and they are basically the same Chinese OEM parts that originally came with my computer. (The previous owner didn't know how to take care of his PC and sold it cheaply because the fans were noisy (easy to replace!) and the windows software needed an update. Lol.) I was very tempted to buy it before buying it to do just blow compressed air in and use the same noisy fans but decided why take the risk my computer heals me fine and it's a really good price so why not? As it turned out, it was a very profitable investment. 5 stars for now as it's only day one but everything looks good so far. My old fans were still running, but they got very loud under load and my computer got very hot. I took the fans off and damn they were awful. Glad these guys helped! The fans come in a box and are wrapped in plastic bubbles to avoid damaging the very thin fan. I have ordered other (2) fans from another seller here and #1 never got me and #2 finally got here 3 days after the scheduled date and without any protection, just in an envelope. BTW: An added bonus is that these fans run faster (previously up to 4000 RPM, now up to 5600+ RPM) since they are brand new, nice and clean! IDK if it's because the motor is better or the blades move freely. But still very cool! In any case. 5 Stars!
