Are fan hubs interchangable?

post #1 of 6
Thread Starter 
I have a 120mm double ball bearing Antec Smartcool that started rattling a few years ago. I was always confused why a double ball bearing fan from Antec would make such rattling noises, and just assumed it was a normal part of wear and tear.

Recently I took apart the Antec fan as part of oiling my sleeve-bearing fans, and discovered that the culprit was actually that my fan hub is cracked and damaged, leading the fan axle to be off center. The rattling comes from the wobbling of the unbalanced fan.

Normally I would throw out the fan, but the double ball bearing motor housing looked solid and usable. I'm thinking about buying a cheap $3 fan from any random place and replacing the damaged fan hub with the cheap one. I was wondering if most fan hubs come in a standard size and format. I was hoping i would be able to get the acoustics of a double ball bearing fan withoug paying the price of a replacement.

P.S. it seems like Antec OEM 3-Speed fans that come with their cases are all sleeve bearing fans, unlike their ball bearing Tricool fans found in retail.

My oem tricools did the same thing. rattled like !@#$. I took both of them out, put in some cm r4's and didn't look back. I don't think your idea is worth it but hey it might work. But I wouldn't be surprised if it didn't fit in your ball bearing housing, having them all the same size is a bit of a stretch.

Well I think the rattling was my fault. It worked fine for a year or two before I once accidentally jammed my finger in the fan while it was running at full tilt. I think the rattling came afterwards, with the damage to the base holding the axle to the hub caused by that incident.

P.S. I also think all Antec 120mm x 25mm fans use the same axle type. I don't know if this is true with other fans.

Fan hubs from different mfg's with different bearing types are not interchangable. If you found the exact fan (Ball Bearing Antec Smartcool), then those parts could be used. But even then, getting an exact fit would be extremely lucky.

You could get the exact match by buying the exact fan. But then . . .

Just toss the innards, use the frame for a shroud.

Fan hubs from different OEMs are not interchangeable.

I've tried and failed to put an Evercool fan hub on a Yate Loon fan and an Everflow fan.
