Best 120mm fan!

Could anyone tell me what 120mm fan that is the best? I am going to use 2 of them on a TRUE, currently I have a Noctua-S12B and it sucks :cry: Price doesn't really matter but what matters is that it can't be too loud, it's ok as long as the sound is the same or lower than my Gainward GTX 260s fans(quite noisy)

Hi, wow you are asking for a lot......if you want something that is not noisy and still moves a lot of air look at these...http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=49&products_id=4073

I have a Scythe S-Flex SFF-21F on my TRUE. I figured that I didn't need a "G" model.

I use these on my Core Contact and S1283:
Scythe DFS123812-3000 "ULTRA KAZE" 120 x 38 mm Case Fan
http://www.newegg.com/Product/Prod [...] 6835185054
Used it on S1283 dropped my temps by 6-7C on a Q6600 @3.6
Note: The KAZE is 38mm thick, normal ones are only 25mm max thick. So it MAY or MAY NOT fit depending on your motherboard and RAM (as in height of RAM).

Scythe SY1225SL12SH 120mm "Slipstream" Case Fan
http://www.newegg.com/Product/Prod [...] 6835185060
Dropped my temps on S1283 by 8C on a E5200 @3.8Ghz

Note: These fans are pretty loud. But in my case, my GPU fan is louder. I can live with it.

If you want quietness for good airflow:

Ok I am not sure but this one seems to be some really heavy, dirty, harda$$ working fan(considering it's noise level)
http://www.newegg.com/Product/Prod [...] 6835608004

Is it good?

Reply to UltraO

not bad but 19.8dba wont be silent ull hear it pretty clear unless u just gonnna keep it at low rpms

Reply to HuntsMan

^Not sure about you guys, but on my Antec 900/1200,etc you can't really hear them unless the fans are ~ 35+dB. GPU fans are louder than that.

19 DBA is pretty close to absolute silence. 35 DBA is audible, but still considered quiet in an average persons home.

Most of the super quiet fans have sleeve bearings which don't last & can become rattly very quickly if you run them on max. Fluid bearing fans are quiet & they last longer & stay quieter longer than sleeve bearing fans.
If you can put up with 1 or 2 decibels in extra noise then nothing beats the old ball bearing type for longivity.

May I suggest this

http://www.newegg.com/Product/Prod [...] 6835103061

19dba and 90 cfm (supposedly) i've found that these ratings are also better than the actually fan. Because I have a coolermaster 1000 case (pretty good silent case) and the stock fans supposedly run at 19dba (I think) but I can hear them, meaning the computer is noticeably quieter without them running.

I think your reading that chart wrong, I don't think it means with no one in it talking, it means like the normal living room, you sitting in it talking.
I'm guessing this because 40-50dba fans are not quiet (like the chart says). They sound like vacumes.

yyup and i have 2 silenx iextrema fans that supposobly push 72cfm and are 14dba both are in the front of an antec 300 case and when on full its pretty quiet but still are heard unless on lower rpms plus the grill in front of the case make it way louder. But i have them running on low rpm so my pc is silent, hard to tell if its on when sitting next to it and pc is at head level.

40-50 dBa can be audible to a point of distraction, but is certainly not as loud as a vacuum cleaner. Your point about the chart being misleading is valid, as "Public rooms in hotels" is a very vague category when defining sound levels.

However, I disagree on 35dBa being as loud as someone talking or normal conversation. Remember that noise levels fall exponentially over distance and AFAIK there is no standard noise measurement distance for case fans, so noise readings can be very misleading.

For example, this Apevia fan is rated at 24.7 dBa, but I found it considerably louder than my Antec 900 fans set on medium which produces 27dBa of noise @ 1 meter. After that, I've always taken sound levels of fans with a grain of salt.

I want to make my case like that.
I have my coolermaster 1000 which isn't as quiet as I'd like it to be, but I just got a fan controller from newegg today and I'm going to tone down my 19dba fans though they won't move any air at all (44 cfm @ 19 equals ? at 12 dba)

Reply to tkgclimb

Hmm I have been wondering this myself Im looking for 2 good fans for a push pull config for a termalright true black 120 Im looking for something quite yet moves a good bit of air I figured with a push pull config both fans could have lower rpms and cfm. I was thinking of going with two of these but im not sure if that would be the sweet spot or not. Scythe S-FLEX SFF21E 120mm

Yeah I was exagerating on the vacum cleaner, though they are loud. As far as 35dba being as loud as someone talking, I was just trying to prove the chart wrong, saying that a "working living room" was what it was talking about not a empty living room. And know that I think about it I should have known that 35dba wasn't someone talking (i had some fans @ 40dba), but like you said loudness is exponential and maybe your right next to the person talking or 10 feet away it's hard to explain. (I actually found a really good chart once that rated noises at distances to how a fan would sound at a couple feet away)

I completely know what your talking about, saying that the 25dba fans are louder than the 27's manufactureres and their false advertising.

let me state first that I have no experience in a push pull setup. Although speaking from a merely better fan standpoint those fans aren't great (at least the posted noise and cfm specs, the fancy magnetics and bearings might make them quieter, but I would think that would also lower the dba spec)

Those cooler masters i recommended earlier are 19dba and 90 cfm and cheaper

http://www.newegg.com/Product/Prod [...] 6835103061

I've been looking for fans and those are the best noise to cfm ratio I can find (under 20$), though they aren't super fancy, with special features and such, they are cheap and come from a reliable brand.

Reply to tkgclimb

Thanks I bookmarked it I plan to purchase In a few days unless someone suggests something better I will go with the cooler master fans I have some in my case now their ok

I generally use Scythe Kama for CPU Cooler, Scythe Slip Stream for the case and also Yate Loon for both in Builds' that I put together. :sol:

Reply to Yoosty

in my opinion anything over 20 is loud

20 and under is good although 19 and 18 wont be complete silent, for silence id go with 16 and under But thats just wat i think. pluse depending on how many fans you got the sound will add up if you got more fans running.

i bought a enermax fan pushes 52cfm on full and its 14dba when regulated its between 8-14dba i got 3 fans with 14 dba max but are running on low rpms as my room is not hot. Also my cpu fan is around 50% i would say and everything keeps my pc idle at 27- 34 but its pretty toasty in my room today as no a/c is on, gpu on idle is 44-47, gpu fan is on auto and running at 760rpms, also got 2 stock antec 300 case fans running on low, wen the room temp is decent as in im not sweating or being uncomfortable the temps are 20-26 idle for cpu and stuff like that, as long as the caase has good airflow its all good.

Reply to HuntsMan

^ those silenx fans you have are pretty awesome, but expensive. As for extremely quiet fans but still with good ariflow and price i would reccomend the sytcthe slipstreams.

But for me, I just put high cfm fans and normal noise on a fan controller, and tune them up and down for the conditions. I don't think my case has quiet as good ariflow as yours but still reletively good.

plus I 'm going to do a sweet gpu cooling mod soon, that will lower that fan speed and hopefully cool it better, will post pics if it works.

Yate-loon fans are very good, and cheap.

Reply to skittle

Yate Loon http://www.xoxide.com/yate-loon-hi [...] m=Shopping produces this fan, and at 88cfm and 40dba, it's loud.

Reply to tkgclimb

Ok listen i have a fan that does 100cfm and is 1db @ 20 meters....does that make sense to any of you? You all fail to realize that noise is measured as decibels per meter, so saying that my fan has a 100 cfm and makes a 19decible noise does not tell you anything at All........Any RESPECTABLE company will make accurate measurements of their fans, 90 cfm and 19db with a 120mm fan is almost blasphemy. I own so many fans that i can be called a fan expert (antec, coolermaster, DELTA, sunon, Comair, SilenX, and many more). i bought silenX fans that claimed a lot of crap and couldnt prove it. Remember any fan can be silent if it is measured at a gazillion meters away from the sound source.......sorry didnt mean to go off at you but do some research and dont go for bogus claims!!.....yateloon is very good btw, they are still 28+db fans @ 1 meter (slow version)...GL

Oh one more thing if you are running 3 fans creating same amount of noise, they will be in phase which will make then create more noise, so if you have one fan rated @ 20db/meter and you put three of those, then your total noise will be 20+3+3 = 26db/meter..sorry physics rules over all companies and their hypes... :pt1cable:

^yes, if you read above we were already discussing the distance and sound thing,

as for the yateloon fans being good buys, I never said it was a bad fan, (great for the price actually) but just for similar airflow it is louder.

As for any fan being silent from far away, this is true.

Coolermaster is a reliable company so there fan measurements like you said should be accurate, As for the decibals not telling you anything I have to disagree, somewhat, these reliable companies as you said will probably all measure the noise of the fan from similar distances which is probably the average distance between you and your computer, and from all the fans I've had from different companies it seems somewhat like that (granted there are differences) my 23dba rosewill fans sound a tad louder than my 19dba coolermasters. Makes sense.

for 19dba and 90 cfm being outrageous how is it
the cfm/dba ratio is 4.7
the 14dba and 74 cfm silenx fan gave a ratio of 5.3 (even better)
and the lower yateloons have similiar ratios and many of the slipstream fans have similiar ratios.

I don't really see what your point is.

Hi, firstly i would like to inform you that cfm is cubic feet per minute, not per meter, so your calculation of 90/19 or 74/14 does not tell me anything except give me a ratio, if you came up with a time function (a differential equation of air flow, sound, and volts that would give me some real info). Secondly i am sure the silenx fans can do 19db but not at their rated cfm, i just test mine again to be sure, i have a noise generator that will create 19 db (up to 80db) and the silenx fan is still louder. Also you might want to look at this about fan rating......look at slienx cfm and noise you will see what i mean...
http://www.xtremesystems.org/forum [...] p?t=170224
this guy did an extensive test......the silenx does provide the rated cfm but look at their decibles. :wahoo:

Reply to freezed1

oh yeah, i am just saying there are many fans out there that will claim to do amazing cfm/db and cost a gazillion bucks but fail to give satisfiable results.

Reply to freezed1

^Yep manufacterors (?) and their false advertising, you got to love it.

and all I was trying to give you was ratio, just to compare the cfm/dba of fans

And I'll make a note to myself, silenx fans are louder than specified. thanks

PS: Did you really think I would do more calculus (though I like math) on top of my regular calc class, which I just started so don't really know any calc yet.

i would say that the silenx fan is quiet but when my front grill is off. And wen the fan runs on full it truly is quiet, i just listen to see if its comfortable to sit next to, but if i had to buy a fan again i would buy the enermax as i got one recently its rated 54cfm at 14dba or so and its 20bucks and quiet at full. Maybe what i realized is the silenx fans dont make that buzzing or humming or whatever you wanna call it noise when the fan is running full speed.

but as u guys said they are overratted a bit but they push a good amount of air and low noise. i will see how loud is 1 as i have 2 of them running.

Hi, yes it is usually the pitch you are refereing to, also the fan bearings make a huge difference how loud oe silent the fan is..generally magnetic bearing > ball bearing > sleeve bearing. You can also make a bearing out of magnetic field which in theory will have no metal to metal contact, thus being quite....magnetic fields act like vectors and follow the right / left hand rule.

Reply to freezed1

SilentX fans suck. They exaggerate the specs a ton.

San Ace 1011s are pretty awesome, but hard to find.

Scythe GT 1850/1450's are also nice.

Zalman ZM-F3's and Petras Yates are great for the price, but you can't mount them horizontally.

Hey just wanted to let you guys know, that the coolermaster fan i reccomended
http://www.newegg.com/Product/Prod [...] 6835103061

pushes less air than stated. This is actually neweggs fault not coolermaster, since the CFM on the packaging is right, stating 70cfm, neweggg specs 90cfm.

That was partially the cause of some discussion here. And though the dba ratings are the same on the package and at newegg, i have to say it's actually a little louder than 19 by my personal use. (also gets a lot louder if there is something like a grill or a air blockage near it, which is understandable, but it gets a lot louder)

well newegg just informed that 70fcm and 19dba is stock settings (whatever that means) and to get up to 90cfm you have to use a fan controller, and then it's at 23dba. But the thing is I can't tell a difference when it's plugged into a fan controller on max, the psu, or a mobo header.
