"Alien Inferno" LED Fan Flame Mod
The flame mod went through no less than five revisions and was a
project in the making for a good amount of time, many ideas were swapped back
and forth on how best to make a simulated flame and the end result is entirely
worth the time invested. The finished mod compliments the alien theme of
the case, it looks like an other worldly flame and really sets off the entire
top of the case.
If your case does not have a top blowhole then
the first step to doing this mod is cutting one. For the hole shown below
an 80mm hole saw was used, a Dremel would also work but is the long way to do
it. After your hole is cut you should file the edges smooth. Notice
that there is also a fan grill ring on top of the blowhole, I used a Dremel with
a cut off wheel to remove the center from an alien fan grill I had lying around
and then filed the edges where the cuts were made.
For the fan flame mod I used 2 80mm Cooler Master blue
fans, one I cut the guts out of so it would act as a funnel for the other
fan. To light it all up I used four Laser LED Cannons, two blue and two green.
After trying a few different types of cloth
with mixed results I finally found one that worked well, silk. The flames
were cut free hand and if you look closely you can see the slits that were cut
to connect them together, one down the middle on the top of one and the other up
the bottom. I affixed a small piece of Velcro to the bottom corners of
both pieces of silk, these will hold the cloth in place. I also used a
small amount of white tape on the slits to keep both pieces of silk connected
and also to add a small amount of support to the flame.
I screwed the blank fan frame to the
Coolermaster LED fan, making note of the airflow direction (it has to blow out)
and then removed the LED cannons from their clips. I drilled a small hole
into each clip and attached one to each corner of the fan as shown in the
picture below. The cloth flames were then attached to the inside of the
funnel in an X pattern using the aforementioned Velcro tabs.
Since I wanted to be able to turn the fan and
LED's on and off independent of each other I hooked up a couple on/off switches in
the front of my case where the USB ports would normally be. Front mounting
the switches makes the best sense because reaching behind the PC to turn things
on/off blows, and since the front USB ports aren't hooked up or used it winds up
being an excellent way to stealth them.
To eliminate wiring clutter I removed the Molex
ends from the LED cannons and wired them all together and used heat shrink to
keep everything neat. In the picture below you can see the yellow wire
going to the LED cannons, it was pre-wired to the switch used and is not
a 12v line... LED cannons are 5v and we don't want anyone getting confused and
burning up a bunch of LED's... unless they are the type to only look at the
pictures and not read the guide, to them we say "have fun" (but they
never hear us because they don't read).
Below shows the fan with the LED cannons
connected, the fan grill was added as an afterthought... hearing what an LED
cannon caught in an 80mm fan sounds like motivates afterthought. The grill
also prevents the wiring or anything else getting caught up in the fan, which is
important if you poke around in your case a lot.
Adjust the LED cannons so that they shine up
through the fan and onto the silk and then position it inside the top of the
case. Screw everything down and plug the fan and LED cannons into their
respective Molex ends. Mouse over the picture below to see how good it
looks in the dark.
also took a short video of the alien inferno fan flame in action because a still
picture cannot do this mod justice. Please right click and choose
"save target as" instead of streaming it directly, see a short video
of the fan mod in
action here. Below is a close up of the
flame taken at night with no flash, pretty sweet.
alien inferno fan flame mod is something that most modders should have little
trouble recreating if they follow the above guide. I am entirely happy
with the way this turned out and everyone that has seen it agrees that it does a
fine job of imitating flames coming out of the top of my case. I estimate
the complete cost of this mod at under $25 USD, not bad for how cool the effect
