*20 - 50% CFM increase and add more static pressure to your fans - Magnet Super Charging

post #1 of 71
Thread Starter 
*results may vary depending on the host fan module. (( aka fan motor )) / fan blade

This is my very first experiment so.... be nice.

Note: This only works if the fan's internal spacing is large enough to fit the second magnet ring. tongue.gif good luck....

If you donate some broken fan's i'll be glad to make tutorials on which fans are able to support magnet swapping!

Items needed:
2x 120MM fans ( Mandatory)

Paracord ( optional )
Lighter ( optional )
Razer sharp sheers / Razer blade ( optional: May need it to cut the sheet Magnet to size )

Very thin flat head ( mandatory )

Patience - Also mandatory


Fan Dis-assembly if needed.... its pretty straight forward.

http://www.thebestcasescenario.com/forum/showthread.php?t=15191


My work:

450

Here are 2 fan assembly's I took apart. (( As you can see, I took the flat head and pry'd the magnet of the second fan,

BECAREFUL, do not damage the magnet too much.

450

Remove the magnet.

450

Praise the heart of a broken gentle typhoon! (( aka magnet! )) As you will notice, its properties are quite flexible.

450

Prepare the fan to be super charged.

450

Place the magnet into desired possition/ also gauge how much space you need to cut, if the magnet doesn't fit.

450

Press in the magnet (( make sure its a snug fit ))

450

Finished magnet (( its ok If your magnet is flush, or it doesn't touch like mines, Centripetal force will keep it in place ... especially at 1600 RPM LOL, actually, I strongly suggest gluing these down. and Make sure the glue dries! or it will impede your RPM ))

450

Re-assemble fan smile.gif

450

Make sure you add a bit of lube to the fan.

Yes, I painted the fan while doing this tut,

However I screwed up the paint job because I touched the clearcoat before it was dry. doh.gif



Project notes:


Super Edit:

I would say after this, It would be smart to get a fan with a small motor, yet get TWO of the SAME fans
Or you might experience some odd fan noise if you angle the fans too much. tongue.gif

ANOTHER UPDATE:

I suggest gluing down the magnet tongue.gif

Nope, If it was, its about 1-2DB higher,

However, if you don't glue down the magnet, eventually it will slide forward and it will rub slightly and you get some friction noise, however glue fixes all these problems smile.gif

Interesting finding. So it increases the cfm and static pressure of fans without increasing db by much? I wonder why this happens. I think I'll do some testing myself

Indeed, Then again I had a High CFM / Low RPM fan to begin with
