which case fan better?

-sleeve bearing
-ball bearing
-what others?

need help.
thanks

sleeve is more silent......

ball is louder than sleeve and it lasts longer than sleeve.

there are other bearings out there...just that i cant remember at the moment

There's sleeve bearing
There's 1 ball which is a ball+sleeve combo
There's 2 ball which is self explanatory

There's also all those blah blah blah maglev lar.... rifle lar, hydro lar...etc....but basically they just mean variation of the theme and different lubricant niah. Hahahaha....

Generally speaking:

Sleeve's quieter but has lower MTBF (means mampus cepat)
Ball's noisier but has higher MTBF

However, each individual fan model has its own sound characteristic...like a 26dba fan could sound noisier than a 32dba fan. Specs just don't describe this so the best way is to hear it first.

edit: Crap grammar to bad grammar

Oh yeah..i agreed. Honestly i also dunno what the hell is meaning by those dba, ball bearing,etc. I only feel the wind blow from the fan and only observed the rpm listed on the fan sticker. <--bad attitude haah

nice info there. Help a lot on my 2nd system setup..

yesterday i just bought few unit of these case fan for RM 8.90 each
cooler master Case Fan (SAF-S82)

Fan Dimension 80x80x25 mm
Fan Speed 2500 rpm
Fan Airflow 32.11 CFM
Fan Life Expectance 30,000 hrs
Bearing Type Sleeve Bearing
Voltage Rating 12V
Input Current 0.15 A
Input Power 1.80W
Noise Level 25.0 dBA
Connector 3 Pin (4 Pin adaptor is included)
Weight 75g

And your question is?

eddysam, how much you bought that? Where?

izzit good or not?
because stated there as 2500 rpm at 25dbA.

i bought it for RM8.90 at tesco puchong

try test it, c how is the air flow good?
cannot rely on spec written oni....

i use vantec 8cm LED fan, dual ball bearing, very noicy but good air flow;

That vantec damn noisy lar....the "feel" part is actually the pressure.

Those would be more useful if there's a restrictive grill...if it's just an open hole or wire grill...those CM's would suffice.

yes ---> 3000rpm speed;
before this was using icute fan, but dont feel any wind push out....
so i change to vantec, haha i dun care bout the noise, air flow faster more important;

Cekap... Hero mentality .... if don't care about noise, then you must try Delta FFB and GFB already.. the choice of heroes...Pilihan Juara...the AK-47's of fans

ive been trying real hard to look for the GFBs or even the TFBs...cant seem to find them anywhere.....

n agree with sniper on the deltas...bad ass fans man!! myself have 2 FFBs in the case....now if only i could find another 12cm ffb that runs on 5v...itll be excellent

tht is abit too much for me, i've saw this fan before last time is like rm80?
way too expensive for me;
i'm satisfy with my vantec for now

How about this fan?

Manufacturer:
Scythe Co., Ltd.
Compatibility:
Standard 5.25" Bay
Combined Dimensions:
146 x 127 x 41mm
Weight:
345g (Case) + 156g (Fan)
FanSpec
Dimensions:120 x 120 x 25mm
Speed: 800rpm
Noise Level: 12.8dBA
Air Flow: 30.5 CFM

Booest might know...but personally, 120mm fan's below 1000rpm are inaudible so it doesn't matter if the specs says 13dba or 26dba. Only thing to watch out for is those irritating clicking sound.
Hence something like a CM UV @7V is fine. Easier to find summore.

is this the badass fan that can push 220cfm?

this baby cries very noisy and loud.

@vervain
the link sniper put in are 80mm fans...i think the deltas that pushes around 220 cfm would be the 12cm TFB series.
