(1 Pair) New CPU GPU Cooling Fans Intended for Acer Nitro AN515-55 AN515-57 AN517-52 PH315-53 Series Laptop DC5V (1 Pair Fan)

Fans are a direct fit physically, but according to Nirto Sense on the computer, the replacement fan is turning at 4687 rpm where as the oem is running at 5769 rpm. There is a noticeable difference in air flow but its minimal. It's still better than no fan at all though. If you're a hard-core gamer, it's something to consider but for me it's probably fine.One picture is with both fans installed both at 4,6xx rpms, while the other picture is with the right oem fan and the left replacement fan.

Really awesome replacement fan for the acer nitro laptop I had fixed up for my friend! Camera in a small box with little protection so I was extremely worried it was broken but thankfully it wasn't. Easy to install if you aren't a noob at computer repairs

Fan does not function whatsoever even though it’s a perfect fit. Spent 3 hours messing with computer settings hoping it would make a difference. It did not.

This product was used in an Acer Nitro 5 Gaming Laptop to replace failing OEM fan approximately 1+ year ago and has been working perfectly. Would purchase again.

Powered on right away and running well. Thank you!

Got it quick and replaced it with no problem.

One of the fans was not an OEM fan and caused a short on the motherboard in my Acer Nitro 5. The laptop booted up for a few seconds then immediately shut off and would not power back on. I took it to a technician who identified the short for me and after a quick repair and reinstalling the original fan I was back up and running. I do not recommend purchasing these. Buying parts is always a lottery so I'm sure some shipments will work, this was simply my experience and I do not recommend purchasing these.

very easy to install
