Powered by AMD, or How to Kool Your R/R

[Guest]

Rummaging through my spare PC parts, I came upon an 80mm case fan. I also found a low profile 80mm CPU fan from an OEM AMD CPU. both had been there for years, so I tried the fit on a duaneage R/R I had sitting on the workbench. I selected the CPU fan (the case fan proved too tall and hit the sidecover when installed on the bike). After a bit of trimming and some wiring, I connected it to the sense wire of the R/R and put the ground to the same ground as my R/R. This particular fan also had a sense wire, so I had to connect that also. Using zip ties, I tied it to my R/R and tested it. It does spin, which should allow the R/R to run a bit cooler:



Just a thought.

Not a bad idea. I think Ill relocate mine while Im changing things up. OR, When I redo the side panels since I lost one in the crash, Ill make it a little better for air flow.

Good thinking! I've got an old Dell laying around, might just have to rob the fan out of it!

The computer fan runs off of 12 volts ?

Yup. I found a pinout, which was basically this:
Pin 1: Black - ground
Pin 2: Red or yellow - 12Volts
Pin 3 Red or yellow - sense wire (must be powered for fan to run, so I tied them together)
Pin 4: Blue - control, for those that have variable fan speeds for quiet operation. I cut this one off so the fan will run full speed.

For the most part, computers use 12V DC or 5V DC. Fans use 12V. A low profile case fan or even VPU (video card) fan will suffice. You could even use a smaller fan (40mm and up) if you had one laying around. I did not.
The only odd thing is hearing the fan when I turn the switch on before starting the bike.

Do they get that hot to justify the hassle?

Hilarious.....and brilliant!

Make an upgrade to this. http://www.newegg.com/Product/Produc...ermaster%20212

Haha, that's the heat sink I have on my PC!!!

[Gonzo]

Me too. Excellent cooler. I think I will be using this mod though when I get around to taking care of the electrical system though Koolaid. Pretty cool and it puts a touch of "geek" on the bike.

& when the fan breaks down it'll be sitting there impeding airflow...

Overkill in my opinion but shouldn't hurt anything as long as you check it's running.....

[posplayr]

have you put a temp sensor on the r/r to see if there is any difference?

[1_v8_merc]

Haha that's Awesome!

One hell of a conversation piece for us computer guys!
(and AMD fans)

I have about 3 or 4 AMD's laying in my basement.

Your thread is giving me ideas.....what ELSE can we cool on the GS?

Or what other CPU parts can we stick on the bike?

Many new bikes have the R/R mounted on the frame down tubes in front of the engine to benefit form air flow.
Could we do this?

Interesting. My GPz has it mounted in the frame tubes.
