DIY Guide to Removing & Installing PC Cooling Fan External Retaining Ring with Mnpctech C-Clip Pliers.
The Nidec-Servo's Scythe Gentle Typhoon (Model# D122C). This fan has been regarded as the best static pressure optimized fan by DIY PC community since it's release in 2008. The original D122C is no longer made, but there is limited stock available at some online retailers. Last year the D122C Scythe GT fan was resurrected and manufactured as "Darkside Black Edition" by Dazmode. It's the same specs as the original, but now has Black fan blades. Many PC Modders including myself have painted these fans to fit the color schemes of our custom PC builds. I've been asked several times over the years how to remove the metal c-clip without losing or breaking it?*This is my DIY guide to removing and installing external retaining ring or c-clip. Like many others, I've also lost these tiny c-clips while learning the best technique for handling this task.

Perform this task with Safety Glasses, the tiny Black metal retaining ring (c-clip) can and likely will pop off, so perform this task in a clean workspace, so you can find it. I suggest doing the work on a large white bed sheet and holding a large magnet near the fan hub as you remove and re-install the c-clip, to increase you're chances of not losing the c-clip. I haven't found a source for ordering replacement c-clips yet, but I'm still searching.
Here is my suggested Tools & Supplies
Safety Glasses (not pictured)
Heat Gun for removing the fan label. Hair Dryer on HIGH setting will work as well.
10" Wire Cable Tie
Large magnet (not pictured)
Mnpctech External Fixed-Tip Retaining Ring Pliers
Needle Nose Pliers
Super Glue (not pictured)
The fan blade looks as if it would snap-on and off, but not the case.
We need to remove the back label to access the external metal c-clip on the fan shaft.
Swipe heat gun or hair dryer back and forth over the label.
Use the Tweezer to peel off the fan label.
Stick the fan label on a clean metal surface while you perform your work.
You will tie down the fan hub with this Twisty tie. The fan shaft has a retention spring inside. You need to compress this spring, so you can remove the metal c-clip. If you don't, it's almost a guarantee that the c-clip will fly off the shaft faster than a bullet.
Using Twisty tie to compress the fan hub spring, by tying down the hub to the fan frame.
Close ups of the Black metal c-clip inside the Nidec-Servo Scythe Gentle Typhoon.
Insert the two prongs of the Retaining Ring Plier inside the jaw of the c-clip.
If you have a large Magnet, Position it near the fan hub, just in case the c-clip pops off.
Holding the black metal c-clip in the Retaining Ring Plier
You will widen the jaw of the c-clip while removing it. You need to bend it back to it's original opening, so it maintains it's grip.
Hold the c-clip in the Tweezer while using a Needle Nose Plier to compress jaw of the c-clip.
Doing this will allow you to re-use the metal c-clip.
If you're wanting to paint your PC cooling fan. You can watch this video guide by Mnpctech

To re-install the metal fan c-clip, grip the c-clip in reverse position on the Plier.
Reversing the c-clip on the plier will make it easier to re-install the metal cooling fan c-clip
Reversing the c-clip in the Plier will make it easier to re-install the metal cooling fan c-clip.
If the cooling fan label has very little adhesion left, I'll apply drops of Krazy or Super Glue to re-apply the label.
The job is finished!
