Yees, love Classic Coke!


For the EK 360 XTX Radiator I'll be using 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.


Nidec-Servo's Scythe Gentle Typhoon Factory Spec PDF link, http://www.nidec-servo.com/en/digital/pdf/D1225C.pdf*

Speed: *2150RPM

Air performance : 68.8CFM

Nose: 34db (25cm from the fan, free air)

Power: 12VDC, 0.123A (0.63A peak max)

Operational voltage range: 5-12V (~900rpm-2150rpm)

Bearing: Ball

Expected life: 100000h/35c or 55000h/60c

Appearance: Full black

Dimensions: *119 x 119 x 25 mm / 4.68 x 4.68 x 0.98 in





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)

External Fixed-Tip Retaining Ring Pliers, http://www.saeproducts.com/retaining-ring-tool.html


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 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 and 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.




Here is the Scythe Gentle Typhoon 120mm Cooling fan dismantled, next step is choosing whether to apply the GULF Blue or Orange, or both colors?

I debated about which color to paint the Scythe GTs for EK's 360 XTX Radiator. Decided to leave the fan blade hubs their factory grey and paint the frames GULF Blue, which works together and helps break up all of the orange.

Glad you liked the theme, and Thank you for watching! Re-assembled the GTs yesterday with these replacement C-clip Retainer Rings that fit Gentle Typhoon fan axels, http://mnpctech.com/case-mods-gaming-pc-liquid-modding-custom-computer-mnpctech-overclock-cooling-fan-grills/ball-bearing-pc-cooling-fan-external-retaining-ring-or-c-clip-pliers-clone.html 








I use two micro flat head screw drivers to snap the c-clip over the fan motor axle / shaft

EK's 360mm XTX radiator has convenient port on bottom for draining your loop. I'm using a Koolance Drain Valve with two of their swiveling 90 degree "snake" extensions.(Bitspower also makes a nice drain valve)




Koolance Drain valve (4 way Splitter won't be used in this build)




I'm using two of these Koolance swiveling 90 degree "snake" extensions. The others were used in Origin PC build, http://mnpctech.com/genesis-the-evolution-of-the-mod-munky-staff-project-with-origin-pc-genesis-full-tower.html






The two swiveling 90 degree "snake" extensions allow you to angle the drain valve under the Mastercase bezel and foot.




Having the drain valve outside of the chassis makes periodic maintenance of draining and refilling the liquid loop easy.

Only had few minutes yesterday to work on my build. Decided on Black wire fan grills for the GTs. I like the look. I guess some would call them "old school" when compared to vast array of fan grills available today, btw All of the machined aluminum parts for Deep Silver's Homefront: Revolution Gaming PC are getting finished, so I'm dividing workshop time between both builds. What a contrast lol, from "don't scratch the paint!" on "what is the best grit to score this finish"on Homefront.


I also swapped out the Black factory thumbscrews for Mastercase SSD trays to machined knurled silver aluminum.

I scored this Gigabyte OC Force Z87X MB from a friend and I'm watching Ebay for deal on Core i7, socket 1150 4790K 4.0 or 4770K 3.5, then I'll need to get a water block for the CPU. Still debating on GPU(s)
