Introduction

This guide works for the AN515-52-50WX, AN515-52-73LN and AN515-52-78AS models. The main discrepancies between these models that concern this guide is whether or not there is a secondary drive installed, in which case it will need to be removed. It should also be noted that because this device does allow the user to install one on their own that if you installed a secondary drive yourself, or a third party distributor did , you will still need to remove it to complete the repair.

The exterior cover of the device, as well as the secondary drive mentioned above, will need to be removed to access the fans of the device which you will then remove to either remove blockage, reseat the bearing, or reapply adhesive to secure the fan. When choosing a replacement adhesive it is recommended that you choose an adhesive that can withstand temperatures up to 212 degrees Fahrenheit or 100 degrees Celsius. It is also recommended that you choose an adhesive that does not expand after application as this can cause the position of the fan to shift and inhibit its rotation. When in doubt something like Loctite super glue is always a good option.

After completing the guide and reassembling your device both of the fans should spin freely without any grinding noise when the device is running. If however your fans fail to function even after completing this guide you will need to purchase a replacement fan, which can be found here. It should also be noted that the fans used in the Nitro V are the same fans that Acer uses in their Aspire line of devices, so don’t worry if you see that when you are searching for replacement fans. After you have purchased your new fans you can also install them using this guide.

Remove the four 4 mm Phillips #0 screws that secure the drive tray.
Using the silver tab located on the top of the drive tray, gently lift the drive tray out of the laptop and rest it towards the back of the device.
Gently remove the SATA connector located on the bottom of the drive by pulling directly away from the drive whilst gripping the plastic connector not the wire.

Step 8

Using a dry cotton swab remove any blockage in the fan channel that is preventing the fan from rotating.
If the fan bearing has unseated, gently grip the fan housing as shown in the second image and pinch it until there is a tactile bump and the fan rotates freely.
You can tell if your fan bearing is not seated properly if the channel is clear but the fan still resists rotation.
If the stock adhesive has failed and the motor is no longer secured to the housing, apply pea sized amount of adhesive to a cotton swab and spread it evenly along the bottom of the motor. Repeat the pinching motion in the second image.
An adhesive that does not degrade under heat or expand is recommended. In my case I used Loctite Super Glue Gel.
Allow the adhesive to cure for the amount of time that the manufacturer suggests.

Step 9

Reassemble following the previous steps in reverse order. Ensure that the fan cables are plugged back in in the correct orientation.
For the left fan the wire furthest away from you should be red, followed by yellow and then back. For the fan on the right the wire furthest to the left should be red, followed by yellow and then black
Remember to plug your drive back in if you had to remove it in step three.
