suggestion for a 120mm

evilgawd · Post by **evilgawd** » Wed May 25, 2005 4:10 pm

Hi , i want to change my 3 120mm for something quieter. Ive crawled the net to read here and there cfm vs dba .... Anyway right now my 120 are adda 72cfm at 34 dba .

I was looking at getting abit more cfm and dropping the dba to something around 30dba.

Ive came across this Antec PRO 120mm DBB
# Ball Bearing design
# Volumetric Airflow 79 CFM
# Fan Speed 2,000 rpm
# Acoustic Noise 29.8 dBA

This just sound too good to be true, i mean 30 dba and 79 cfm .... wow

As anyone tested this fan? So far the closest thing to these spec are the panoflo m1a 85cfm at 35 dba ... and 35 dba is too much ....

Awaiting your comments !

thnx

Are you crazy. You need some of these. You want to slow everything down to about 500 or 600 rpm. I'm just kidding, not about the fan speed but I'm sure you're not crazy or I guess its possible but we don't care about that here. You want less rather than more. Don't worry about cfm just go as slow as you can and still cool things down if your goal is to make things quieter.

The antecs are ok, but just too powerful. It all depends on you computer and what you want to do with it I guess. - FG

hehe ya prob is my tower is quite full

temp :
cpu = 47 c
nb 35c
case 35 c

so basicly 1 of the 120 is only for the drive. The 2 other are creating an airflow over the cpu to cool it a bit. I dont know if i could go lower then 30 dba with all the heat

Lian Li v1100
Antec neo power 480w
Abit ic7-g max 2
p4 3.2c with zalman 7000 al-cu
2x512 corsair twinX
Ati radeon 9800 pro 128 meg
1x WD raptor 36 gig
2x Seagate 250 gig
2x Plexwritter 40x
Pionner dvd-rw
Soundblaster live 5.1

So yea im from the oc league and trying to go over the silent one

So basicly at the moment its a bit noisy , 3x 34db, rougly 40 db just with the 3 fan...
You think i could drop cfm ??

I see what you mean. I would get globes from the german Silencio_777. Look for his user name under vendors and deals in the forums. They are about 1450 - 1500 rpm. They could do the job and still be quiet. I think the prices are better than the antecs - maybe not that much but a little bit. - FG

I know your case has the psu on the bottom but I can't really picture it. I will have to look it up.

Cheaper is relative , im from montreal, so my guess is ordering from oversea will be pricier ;)

Yeah, a Globe S1202512L-3M would be a great fit for you.

Good luck! Oh, and don't be bashful for being from/of the OCing league. You can still be a OCer and have a quiet rig. It just takes know now. And you've come to the right place for quiet/silent related knowhow!

Pair info gleaned here with that of places like ProCooling and OCing sites, and you're all set. A dash of bit-tech.net is good too if asthetics is your thing as well.

The Globes will give you a near best quietness when run at their min voltage, but also give you CFM on demand. So OCing is still no problem with the help of a bay mounted or smart fan controller. Remember though, CFM is all about location. Doesn't do you a bit of good if the critical area isn't getting the airflow.

Oh, and Welcome to SPCR!

Edit: If you don't want to go the Globle route due to costs, try the Yate Loon D12SM-12 from here:

Hi,

Here's the link for Silencio's shipping. Shipping (for example) 2-3 120mm fans to Montreal would be ~4 - ~6euros, about 5-8USD.

I've talked about the Globes vs Yate Loons with frankgehry. Personally I find my Globes to be a bit better than the D12SM-12 Yate Loons with tacho.

frankgehry · Post by **frankgehry** » Wed May 25, 2005 11:28 pm

I think the yate loons at pctekonline are really young lins now. He has made several substitution without telling anybody. He could have the D12SM-12's back by now but I would just check with him personally if you really want D12SM-12's. They also do not have tachs, but the one I bought were really good. - FG

Welp this idea grown on me over the night, having my 3 120 controlled by something like http://www.adpmods.com/case-modding/Sil ... p-253.html
or
http://www.adpmods.com/case-modding/Sun ... -1301.html
First one looks better

That would be sweet, when i compile i just drive em up , when im idle on the puter i let them stay low .

As for the fan , i was looking at the Panaflo FBA12G12U1A or FBA12G12H1A, which look nice.
Thing is id like to order all at the same place to save some $$ ;)
you think that would be a quiet at low voltage ? If this is not a good choice ill order the fan elsewhere.

You guys are talking about globe vs yate loons.... these are better/quieter then panaflo? Sorry for asking dumb questions ;)

StarfishChris · Post by **StarfishChris** » Thu May 26, 2005 8:21 am

-U1A and -H1A are ultra-high and high speeds. They'll be very noisy at low voltage, I'd recommend getting an M1A at most (preferably L1A) but Panaflo 120mms aren't the same as 92 and below. I think a Globe or Yate Loon would be a better choice.

evilgawd · Post by **evilgawd** » Thu May 26, 2005 8:55 am

Thing is , at the moment its 72 cfm. Basicly i want to be able to drop it when idle but to raise it when the system gets hot . The M1A might be a better idea like you mention. at full speed it drive 86.5 which is better then what i got now. With the globe & yate loons , problem is both of them are lower cfm then my actual fan. So what i want in my perfect world is a fan with more cfm at full speed and the ability to be quiet at lower voltage :)

Im just wondering if it would be quiet at lower voltage ... anyone has experience with these fan?

evilgawd · Post by **evilgawd** » Thu May 26, 2005 10:51 am

Ok looks like ill go for the sunbeam rheobus & 3 panaflo M1A unless someone has a better idea ;)

Aleksi · Post by **Aleksi** » Thu May 26, 2005 10:58 am

Hi,

I don't have any personal experience with the 120mm Panaflos, but the it seems most people don't prefer. I can understand your situation, these kind of fans are hard to find.

But personally I would be looking at Papst instead of Panaflo if you seriously need that big airflow. But your location can be a bit problematic, most likely you would have to order from europe... Tough situation!

evilgawd · Post by **evilgawd** » Thu May 26, 2005 11:29 am

I could only see the papst 120mm 4412 which is only 67 cfm, do you know of a more powerfull one ?

Aleksi · Post by **Aleksi** » Thu May 26, 2005 11:39 am

Hi,

here's a few 120mm fans from the Papst website, they don't have the tachosignal, but I'm guessing it doesn't matter as the Panaflos don't have it either?

4412 FGL 12 VDC 94,0 m3/h 1600 min-1 1,25 W 26 dB(A)4412 FGML 12 VDC 114,0 m3/h 1950 min-1 2,00 W 32 dB(A)
4412 FML 12 VDC 114,0 m3/h 1950 min-1 2,00 W 32 dB(A)
4412 FGM 12 VDC 140,0 m3/h 2400 min-1 3,20 W 38 dB(A)4412 FM 12 VDC 140,0 m3/h 2400 min-1 3,20 W 38 dB(A)4412 FG 12 VDC 170,0 m3/h 2900 min-1 5,30 W 43 dB(A)

if the model has "F/2" in it, it means it has the tachosignal. Here's some of the Papsts sold commonly in europe:

Papst 4412F/2GL
Papst 4412F/2GLL
Papst 4412F/2GML
Papst 4412F/2M
Papst 4412FGL
Papst 4412FM

So the problem remains the same; you will probably have a hard time getting hold of these in north america. However, I would try some of the canadian industrial sellers, as they may well have these.

But unless you take the Panaflo, it seems you would have to order from europe. Many stores charge >20€ for shipping to north america, if they ship at all there.

cyberknight · Post by **cyberknight** » Thu May 26, 2005 11:39 am

30dBA is pretty loud, yo.

anyways, I personally have an Antec Pro 120mm in my Sonata. I connect it to the FAN ONLY and it spins at a quite 1000-1100RPM. It's very quiet and virtually no motor noise at that speed. Good quality fan.

but if you want to 12V it and have it run at 2000RPM, that's loud even by a non-silent PC enthusiast.

ive just found this french review on the papst

if you look at the bottom they show up dba vs volt of 3 fan

http://www.matbe.com/articles/refroid/1 ... pstdba.gif

The 4412FGM look like it would be a nice match with the sunbeam rheobus . Altho it looks impossible to find hehe weeee

DrCR · Post by **DrCR** » Thu May 26, 2005 2:36 pm

Don't go the Panaflo route! About 99% of the samples just won't quiet down. You already know my suggestion (not suggestions as according to frank's post pctekonline is a no-go now). I would most seriously recommend the Globe to you, but by all means feel free to look around. Most Papsts are good fans, just harder to get ahold of some of them.

Edit: If you want some bling-bling, this is a good fan for quieterness at minV, asthetics, and CFM on demand.
http://www.mnpctech.com/Globe.html
(notice the link says Globe. Thats because the vendor used to sell the Globes, but then ran out of his supply and now sells this as it's, albiet more pricy, replacement)

Good luck!

Power or silence

http://www.silverstonetek.com/products-fm121.htm

Or put a couple of extra fans that you just turn on for more cooling and turn off when you don't need them.

Or have two globes and two http://www.sidewindercomputers.com/de12trblhisp.html

Mount the delta triple blades in front of the globes. Since there are just 3 blades the the globes will function normally. Then you can turn on the deltas, which will be right in front of the globes. The entire depth will only be 25 + 38 = 63mm.

evilgawd · Post by **evilgawd** » Thu May 26, 2005 3:56 pm

oh man this fm121 sure is sweet to my eyes !!
This fan is pretty new tho , ive only found a few site in the US that carry it , at 30 $ each

As for the Papst 4412FGM, i think i could get my hands on 3 of those for 69 US shipping included, but no connector.

In either case, if i use the sunbeam rheobus on either the papst or silverstone ; i should be able to get nice performance at 9-12v and quiet at 7v right ?

( in silverstone case i dont wanna be stuck to use 3 controller , i know this must sound stupid because they all have fan controller but i just dont wanna be stuck with loud fan if i use another rheobus and drop voltage )

Thank again for all your help guys!!!

You can mod fm121 controllers to move all 3 knobs to one faceplate. This should be easy if you have a drill.

you can save money on rheobus.

The fan itself is a good fan and doesn't make much sound at low voltage.

Edit: frank - thank you for introduction and the link.

evilgawd · Post by **evilgawd** » Thu May 26, 2005 4:56 pm

Thing is i have a lian li tower with 5 x 5.25 and 0x3.25 ( case come with a faceplatte for a floppy but it would be ugly with this )

So my guess is ill have to get one , my concern is about the noise it make when in use with a rheobus

With PWM, fm121 makes motor noise at low duty cycle

Im wondering if ill encounter this problem with the sunbeam , i know the t-ban is kickass but its 3 time the price. If you have some better suggestions for a rheobus under says 40 US $ dont hesitate to tell me :D

ultraboy · Post by **ultraboy** » Thu May 26, 2005 5:13 pm

You should not have problem pairing fm121 with Sunbeam controller since it use voltage drop technic and not PWM.

evilgawd · Post by **evilgawd** » Thu May 26, 2005 5:35 pm

voltage drop technique eh? *scratch his head*

Oh well if its a nice combo ill go for this one !

sunbeam controller + 3 silverstone fm121

Cant wait to see how quiet i can get it to work :)

DrCR · Post by **DrCR** » Thu May 26, 2005 9:53 pm

Good call frank. Just though of the SilverStone fan a little while ago.

evilgawd, the most common way of slowing down a fan is to reduce its voltage. PWM is different. It pluses 12v to the fan and how often/infrequent it sends the pluse determines how fast the fan will run. Don't have time for detail, but that gives you a general idea. Not all fans play nicely with PWM though, so you have to make sure you get a PWM friendly fan if you ever go that route.

evilgawd - Forgot to mention that if you use Sunbeam Rhoebus with fm121 (in fact with any fan) - make sure that your Sunbeam setting would allow fm121 to spin with cold start up.

IIRC, at start up Sunbeam will give to connected fans whatever voltage you set and not 12v., while fm121 starting voltage is around 7V. If your Sunbeam setting is too low you might end up thinking that your fans are spinning so quietly when your turn on your computer and in fact the fans do not start at all.

I suggest you read this article by MikeC on Sunbeam Rhoebus. But you have already done that, right?

evilgawd · Post by **evilgawd** » Fri May 27, 2005 8:32 am

I had read a few review on the sunbeam but not this one , i was actually thinking about this while sleeping , maybe ill take another one which can control the cpu fan also ( most review say to not use the sunbeam with cpu fan) . Also no one mention about voltage and the knob ; and how NOT usefull they are , i mean 6 oclock for 12 v ... eh ? the graph stop at 1 oclock lol

Collermaster aerogate 3 looked nice but its pwm.

There must be something to control 3 fan case & cpu with decent feature ;)
