140mm FDB bearing fans?

post #1 of 9
Thread Starter 
Have been looking for good 140mm fans, I want to get FDB bearing ones but most of the 140mm ones on the market are Sleeve bearing fans.

After doing some research, I have found a few FDB bearing fans but wonder if anyone used these before.

1. Scythe Kama Flex 135mm
Uses FDB(not S-FDB) fans, 135mm fan blades, L, M, H speed versions. Currently out of stock at most if not all US online retailers. Between $15-20.

2. NZXT 140mm FDB fan
NZXT have two 140mm fans, one is FDB and other one is Rifle bearing. The FDB one is around $15, blade design is similar to the Scythe Kama Flex, and have a 3-speed adjuster that allows the fan to operate from 1000rpm to 2000rpm.

3. Bit Fenix 140mm fan
The Bit Fenix fan is relatively cheaper, manufacture claims they uses FDB bearing. Fan speed is relatively low, around 1000rpm. Does not move too much air but pretty quiet. However the construction of the fan is pretty cheap, kind of like Thermaltake quality....Have LED and non-LED version, the non-LED one can be had for around $10 or so, but you get what you pay for....

These are the only 140mm FDB fans that I know, some people say the Thermalright X-Silent 140mm fan also uses FDB bearing, although the manufacture says it's liquid state bearing.

Any other 140mm mount FDB fans out there? Any feedback on any of the fans listed above?

Scythe Kama Flex: I've heard good things about these. The only thing I'd watch out for is I've heard they can develop a clicking noise if you mount them horizontally.

Nzxt 140mm: I can't speak for the FDB version but the Rifle bearing version is a pretty decent fan. Good looks, good airflow, a little loud for my tastes. But I bet it'd sound better if you undervolted it a touch. (9v perhaps?)

Bitfenix 140mm: I haven't used these myself but some people have reported a clicking noise with them but I'm not sure if this is still an issue. I had two 200mm versions for awhile and they were amazing for the noise/airflow.

Thermalright has the X-Silent 140 which I've heard is great for a quiet fan (I've used the 120mm version ^^) but can click when mounted horizontally.

Are you absolutely set on FDB bearings?

Enermax's T.B Silence 140mm is a great quiet fan which can be mounted any which way with it's "Twister" bearing. Looks pretty snazzy as well and the price is right.

Thermalright makes another fan, the TY-140 which is pretty stellar for it's noise to airflow. Although it only has 120mm mounting holes.

Edit: On a side-note I've always wanted to try BeQuiet products but you can't find them anywhere here in the states.

FDB Bearing and Sanyo IC sounds good, but it's not available here in the US...

The Scythe is OOS almost everywhere so I pretty much give up on that option now...

Might try the NZXT one, I just hope it won't be so cheaply constructed like the Bit Fenix. I'm planning on using them at lowest speed if I buy it.

I'm pretty set on FDB unless there's a good ball bearing/double ball bearing alternative(like the Sanyo 9S or Nidec GT, not possible tho lol). I bought some fans with those fancy name bearings before and most of them are not as good as FDB or double ball

The construction on the Nzxt fans is pretty solid considering their price.

And I'll vouch for the Twister bearings (At least on the T.B Silence line). Very durable and very quiet.

Noiseblocker fans are amazing as well but you pay for the quality.

Noiseblocker uses modified sleeve bearing I believe, however the construction quality is great for Noiseblocker

I will take a look at the Twister Bearing fans

Not all modified sleeve bearings are hokey

Great overall fan reference.
