It doesn't exist. You can get a high CFM that will dial down to quieter levels, but not quiet and definitly not silent.Happy Hopping wrote:So there is something that can do the same cfm, and silence, I'll go for it.
Why do you need all this CFM? Trying to take a dually to 2.7GHz on air or something?

How quiet is the Zalman ZM-F3 120MM Sleeve Bearing Case Fan?
Antec TriCool 120MM Case Fan?
If you had to choose between the 2 above, which would you go for?
If you could choose any fan that is out there, which would be good? (no Nexus, too expensive for me... )
Need some help trying to decide what 120mm fans I should get to replace the noisy ones that come with the Thermaltake Tsunami case.

Welcome to SPCR!
Zalman are not known for their fans being particularly quiet, and the Antec 3-speed is really only used if you buy the case that they come with.
I would go for a Scythe DF or a GlobalWin NCB, or a low speed Yate Loon. All are reasonably priced and are pretty darn quiet, especially when undervolted. There are lots of threads where these are discussed.

I realize this is an older post, but I have some info that may be helpful to you or others looking for a replacement for this fan.Happy Hopping wrote:At my friend's workplace, there is a 120 mm system rear cooling fan (measured from edge to edge of the black square is 125 mm). It's not extremely noisy, but clearly you can easily hear the fan noise.
The brand name is called NMB,
http://www.nmbtech.com/index_f.html
and I believe the motor is from this link.
https://www.minebea.co.jp/english/produ ... _2092.html
The printing on the back states:
NMB-MAT
Model 4715KL-04W-B46
12V DC, 0.9A
Minebea-Matsushita Motor Corporation
http://www.trademoon.com/Product368308.aspx
http://www.codemicro.com/store/check_pr ... tid=731132
The fan seems to sell for new at $210.6, or refurb for $86
I have a few questions:
why is this fan so expensive?
What is equivalent that is silent?
I had this fan (NMB-MAT Model 4715KL-04W-B46) in an old compaq proliant 1600r and it died one day. I also searched and found the replacements and prices that you did. I happen to have a spare 1600r and pulled the fan out of it and swapped it. The working fan i pulled was a Nidec Series TA450DC which I was able to order from http://www.xoxide.com/120mm-nidec-fan.html for $14 (for a spare). The server was installed in a rack so I can't tell you if it's any quieter, but it is a heckuva lot cheaper and works with no problems.
Specifications:
Dimensions: 120x120x38mm
Air Flow: 112 CFM
Speed: 3250 RPM
Noise: 48.4 dBA
Voltage: 12 VDC
Voltage Range: 7.0-14 VDC
Current: 490 (mA)
Power: 5.88 W

I'm aware of the Nidec series. But the replacement is much worse as far as noise is concerned.
the old fan is only 68.9 cfm, I forgot what the old noise dB level is, but definitely much lower than 48.4 db
I was thinking of this on a professional HP workstation:
Kill the above 38 mm fan, replace w/ the Nexus 120 mm fan w/ 36.8 cfm but add a 2nd front system Nexus fan.
The question is:
Would that make 36.8+36.8 = 73.6 cfm? Or is it not the same as one fan w/ 68.9 cfm?

It's not the same. Two fans installed in series (which is what you are proposing) does not double the airflow, but it will increase static pressure. To double airflow you want to mount the fans in parallel:Would that make 36.8+36.8 = 73.6 cfm? Or is it not the same as one fan w/ 68.9 cfm?

If I have a fan that is also NMB MAT 120mmx38mm, but rated at 12V 0.4A, and I replace it w/ the above (link) at 0.24A. What would happens besides a reduction of CFM?
Because the HP tower that c/w the above 0.4A NMB at 120mm x 38mm, I look at the spec. the fan is made to support a max. load of 5 hard drives.
So if I only use 2 hard drives, can the fan of the above link works? it's lower cfm but same diameter and thickness

I recently ordered Noctua NF-S12
http://www.noctua.at
# 120mm, 1200RPM
# sound-optimised blade geometry and profile
# self-stabilising oil-pressure bearing (SSO bearing)
# <6dB(A) with U.L.N.A.
# 6 years warranty
It comes ready with a cord that cuts down the voltage
I will post a thread Once I have it .. wheter it is any good.

Ok as my topic here;
viewtopic.php?t=35117
says...
I'm looking for a 120mm fan with a bit more flow then the quietest fans (Scythe 8.7dBA, Nexus...).
I need something to keep an otherwise almost passive system cool and quiet.
Something that moves a bit more air then the nexus but also don't make to much extra noise. Help anyone?

Hello,
The trick is to try to improve the air flow without resorting to faster fans. There are at least two fans that are on par with the Nexus for noise: the GlobalWin NCB and the Scythe DF.sgtspiff wrote:Ok as my topic here;

Hello,
What makes you think that you need two high-speed 120mm to keep it cool? The fast CPU's these days are relatively cool, and while some of the the GPU's are darn hot -- if you have a good case with low restriction on the air flow, two low speed 120mm fans could be plenty.
If you need more air flow -- you cut out the fan grills, and use wire ones. Also, you use more efficient heatsinks. Going to even medium speed (1600RPM+) 120mm would be way too loud.
One or two 700-900RPM 120mm fans is plenty for almost any system, if the rest of it is set up correctly.

I'm between the 1600rpm S-flex that works nicely @5v or this Noctua which i know nothing about. Have you gotten yours yet?nonexite wrote:I recently ordered Noctua NF-S12

I was in at a local store looking for Nexus fans. And the clerk (which after a good talk I understood that he knew what he was talking about) told me that they had gotten plenty complains about the Nexus (the store sells nationwide). The main was simply that they broke to easy.
He said go with a ball bearing fan instead.
What do you guys say about this?
And how much of the "silence" will I loose if I buy a good ball bearing instead of a Nexus (glide bearing that is??)?

Hello,
I'm not sure if I've heard of even one complaint about a Nexus fan breaking? Maybe some have, but if it started happening very much, I'm sure that SPCR would be the place that you would hear about it!
Ball bearing fans can last longer, but they can also be noisier. If you want a BB fan, you might try one of the only ones that has a chance of being quiet: Scythe Minebea NMB, which runs at 1100RPM, and they claim 18dBA and 41CFM. It also has 9 blades, instead of the usual 7, which in theory at least, would tend to allow it to push more air at (a low) RPM.

Has anyone tried the Coolink SWiF series? Would they fit in here? This is their 120mm fan series, looking particularly at the model 1200.

Hi all,
one of my 3 yate loon 120mm fans (the 1600rpm version) recently started making a hell of a noise.
All my fans are attached to a fanmate and run at (estimated) 8v or something like that
They are all a couple of years old (2-3 years) and ran about 70% of the time (so this might be normal wearoff)
Now offcourse I want to replace this hellish noisemaker, so I'm looking around to buy some extra 120mm's
and i noticed some weird things:
in holland the nexus 120mm costs only 6 euro??? which is half of the yate loon 120mm (12 euro)
while according to this forum, the yate loon should be cheaper...
i also saw the post above mentioning that nexus fans brake easily
this scares me a bit off the nexus, although i also know the yate loon isnt perfect either...
personally i do prefer the 1600rpm of the yate loon, as it gives a bit more headroom, but if the nexus would have a longer life + is only half the price, i would like to consider it...
in short: i am doubting
one other thing that i might want to consider is restrictiveness. If I understand it right, I am using them in quite a restrictive environment:
i have a hole in the bottom of my case
on top of that hole is a 1cm thick dustfilter of the thing that sucks air above cooking place
above that filter are 2 yate loon fans sucking air in to the case
and above that is the radiator of my watercooling
does anyone if the nexus handles restrictiveness better then the yate loon at the same rpm?

I would start a new thread in the Fans and Control section, but to go ahead and give you advise I would shy away from any low RPM fans in your case due to your restricted environment, rather restrictive indeed.
Have you considered a "pantyhose" filter? Not sure how bad the dust problem is for you, but that sort does the trick for me. Doesn't work for everyone though; take a look at Bluefront's setups of the the years.
Also, what kind of rad are you using? With few exceptions like the comparatively recent Thermochill and Swiftech rads, rads in and of themselves are rather restrictive so a thick filter just adds to the problem. A pair of Nexus fans on a Thermochill is about as good a SPCR-spec quiet watercooling gets besides passive, but I don't think a YL @ 1k would suffice in your setup. Your setup actually sounds like it could use a nice blower...but that's not exactly on the SPCR side of the quiet scale lol.
I would pickup a couple Scythe S-Flex 1600k SFF21F 120mm fans, but I don't know if they are available in your area of the world.
Hope this at leasts gets you started in the right direction.

thx 4 the info DrCR
I tried with the pantyhose first, but it was too hard to install (it always teared apart when i tried it)
that is why i went for the thick filter (which just lays loose on the bottom of my case)
at first, i was also very sceptical about this, and i do think it does block lots of air, but in the end, it didnt seem to matter much in my case
I have a Thermochill PA120.2 Radiator, a Swiftech Storm G4, a Danger Den Maze 4 Acetal and a Danger Den D5 Pump (all quite nice stuff :p)
I tried overclocking my system without all dust filters and all fans and pump @ max speed to find the maximum speed, and then i tried lowering the fans and pump down
and it doesnt seem like temperature is limiting my a64 3200+ @2600Mhz, so in the end i ran the pump @ minimum speed and all fans at very low speed as well
and the temp still remains very low actually
but... I wont be keeping this cpu forever, and my new cpu might be more sensitive to temperature, so i will take your advice and go for the yate loons again to have more headroom with the higher rpm...

Nice bit of kit you've got there.
Not surprising your temps are OK considering your CPU (assuming you're not overvolting it through the roof). But yeah, if you want to push, say, a QX6600 to 4+GHz you'll be looking at taking things to a whole new level.
In this case personally I would go for the Nexus or better yet a 1200k S-Flex if you can get them, undervolt them as low as your temps will allow, and enjoy the quietness in addition to the OC. Later on when you're ready to lay down a few quid on a new rig, the price of a few additional fans to go with it (should any be needed) should only be a fraction of your purchase.
On the side -- the Storm probably won't perform optimally on any of Intel's "glued" together CPUs. I forget the Barcelona's core dimensions right off, but it may be small enough for the Storm design to shine. Just another bit to think about when upgrade time comes around. Myself, I'm waiting for next-gen vids -- probably will need to go WC just for the vid lol.

I do am overvolting quite a bit (for watercooling at least) but it is not extreme yet (the cpu isnt one of the easiest to overclock :/ )
i can find those s-flex in NL, but they are too expensive (16 euro), for that price i rather buy some nexus (6 euro) or yate loons (12 euro)
I do would like to take these fans over to my next system as well (i have the tendency to buy as much as i can as a long term investment :p) so I'm still thinking about buing some yate loons (although those nexus still remain attractively cheap :p)
You did scare me a bit with your saying that my storm wont do so well with those Intel's
I was hoping my uber expensive and rare (it was one of the last) storm's would be able to freeze my next cpu as well...
This is because the 2 cores are never exactly the same height, right? is there any block that can cool those better then my storm then?
