Fixing My Razer Viper V2 Pro Scroll Wheel
Date: February 17, 2025
Recently, I've been experiencing issues with my Razer Viper mouse's scroll wheel. Sometimes it scrolls in the opposite direction or doesn't register at all. After some research, I found a few potential fixes that i wanted to try out.
The core issue is that according to my research Razer wanted to save a few cents on producing this 150€ Mouse and installed some shitty encoder in the scroll wheel that collects dust like it's life depends on it.
Method 1: Compressed Air
The first and easiest method is to use compressed air to clean the scroll wheel mechanism:
- Spray compressed air into the left side of the scroll wheel where the encoder is installed.
- The issue will be gone or lessened but reappear within ten minutes of use.
Method 2: Replacing the Encoder
As i was not happy with blowing compressed air into my mouse every 10 minutes i decided to replace the crappy encoder razer put into the mouse to save a few cents with a better one.
- Remove the mouse feet to access the screws
- Unscrew the bottom plate
- Carefully open the shell and disconnect any cables
- Clean the scroll wheel mechanism with isopropyl alcohol
- Mount the PCB to some clamps
- Clean the contacts of the encoder
- Apply flux and heat the contacts with your Soldering Iron
- Use a Soldering Wick to "soak" up the now liquid tin
- Once all the contacts are removed, carefully take out the shitty old encoder
- Drop the New Encoder into place
- Apply tin to from new contacts between the PCB and the new encoder
- Clean off any reamining flux
- Reassamble your mouse
As a Guide i used this really nice video from ClickFix on Youtube
I'll update this post with the results of my repair attempt. Wish me luck!

Sooo Yesterday i went ahead and opened up my Mouse, and after figuring out my AliExpress Soldering Iron, i actually managed to successfully swap out the Encoder and fix the scroll wheel.
One small issue though.... perhaps i wasn't careful enough with the soldering iron and accidentally touched the Right Click Switch, so now the right click doesn't work anymore, but that should be fixed rather easily, i will order a replacement and swap it out.
