I don't know where you live, but if it's in Europe, Papst fans are reasonably priced. I can attest that the new 4412 F/2GLL is very quiet indeed. Make sure its the fan with the white and blue sticker.

Hi betty, I experienced a similar phenomenon with my new S12 430W, but with the SATA connector. Most of the time the last connector wouldn't supply power to the drive, very occaisionally it would. The first connector in the line functioned without a hitch, all the other connectors as well. I the end...

Would an 80mm fan on the side CPU vent fit with the Ninja? On the other hand, with the 120mm running at 12V through the Ninja, the airflow may be such, that the air being blown in from a 80mm fan would have little effect on cooling, I suppose as an afterthought. Maybe nevertheless worth a try.

Hi Sizzle,

Your story is definitely an advocate for the Ninja. May have to consider that instead of the SI-120 when planning my upgrade.

I presume you still have all three Papst fans in place. At what voltage are they running now?

Hey hmronin, the S12 has a fan rpm monitor cable - on mine its a two wires, black and blue. It has only the RPM monitoring wire and ground, no power. I just hooked up to my motherboard (ASUS P4PE) and read out the rpms over the Asus PC Probe software. I am not familiar with the T-Balancer, but maybe...

Thanks dukla2000!

In this thread I posted some results based on your formula. Might be interesting for others reading here as well.

Thanks MikeC. It is fun to figure out some things by myself! So, now some concluding remarks from my side. Thanks to dukla2000 in this thread , The standard formula for this is dBA2 = dBA1 - 50 * log (rpm1/rpm2) so a 4412FGL is 7.0dBA @ 5V. Yeah, right! The formula ignores among other things the bea...

MikeCs idea sounds pretty radical, but it wouldn’t be much use to me I suppose, since I have a SLK3000B, where the CPU also plays an exhaust role. I figured this out earlier today - maybe it's helpful for others too: V RPM CFM dBA* AD1212LB-A73GL (Seasonic S12 Fan) 12, 1800,0 72,0 34,4 9,5 1425,0 57...

The same kind of question has been recently bugging me too, but for a different reason. (I am thinking about replacing the stock fan in my S12). Assuming a linear relationship between volt : RPM and volt : CFM, I have figured the following. I would like to know how to figure the dBA on hand differen...

So, after some investigating on my own, I have found the following: ADDA AD1212LB-A73GL (S12 fan) RPM: 1800 CFM: 72 (dBA: 34.4) 2.88W Papst 4412 F/2GL RPM: 1600 CFM: 55 (dBA: 26) 1,25W Papst 4412 F/2GLL RPM: 1200 CFM: 41 (dBA: 18 ) 0,72W Nexus D12SL-12 RPM: 1000 CFM: 37 (dBA: 22.8 ) 1,8W With this d...

I suppose the key points to investigate are: 1. would the Nexus or Papst 4412 F/2GLL start at 4.6V, and 2. what is the cm/h or cf/h for these fans compared to the adda fan at the same low voltages. 3. anything else to consider? If the airflow is comparable to the adda fans, the PSU would be adequate...

I am also interested in considering changing the adda fan in my S12 430. @ frankgehry: is there a reason you did not mention the Nexus 120 or the Papst 4412 f/2GLL? (I believe they are 1000 and 1200 rpm respectively.) They would both be quieter than the fans you mentioned. Do they not push enough ai...

I can second that. My SLK3000B also has mounting holes in the correct position. But the problem I found, is that the holes are just a little to large in order to use slics to decouple the fan.

My opinion? Quit the speculating, worring and bitching. Just look forward to an objective SPCR review, and then deal with the results. You can't please all the people all the time. But you can please some of the people some of the time. Antec has never failed at that. I believe they have certainly p...

Hello all, I just replaced a BeQuiet P5 420W PSU with the Seasonic S12 430W. (Why? Just because I wanted to try out the S12 after having read so much about it. It is finally readily available in Germany.) My system: Antec SLK3000B Asus P4PE P4 2.4 GHz 1 GB Infineon DDR SDRAM Thermalright SI-120 Heat...

Amendment to my above post: I had intended stay with Noiseblocker, until my neighbor convinced me to try Papst for the heck of it (he is a Papst fan). So I did. I moved from a Thermalright XP-90 to the SI-120 with the Papst 4412 F/2GLL. Got another one for the exhaust as well. The first thing I noti...

Wrote too soon. Found this sticky. My question is answered. Thanks anyhow.

Hi, I was wondering how the Nexus Real Quiet Fan fit on the Thermalright SI 120. I heard that the screw holes of the Nexus fan are closed all the way through the frame corners, meaning that there is no where the clips supplied by Thermalright fit to hold it onto the top of the heatsink. Can you comm...

Hello, I don't mean to jump into this discussion with my concerns, but there seems to be a lot of knowledge around here regarding the Thermalright XP 90/120 and SI 120. I just replaced a XP 90 with a Noiseblocker SE2 92mm fan rotating at 1200 rpms giving me a CPU temp of 39C idle and 46C load - with...

Next step: Just ordered a Thermalright SI-120 Heatsink with a Pabst 4412 F/2GLL 120mm fan to replace the Thermalright XP-90 with the Noiseblocker fan. The SI-120 appears to have less air resistance than the XP-90, or even the XP-120. Also a larger fan turning slower should reduce noise. The 92mm Noi...

I am going through the same thing you're starting with. A quote from on my thread summed it up quite nicely: Slowly the silent bug will affect you. At first your newly born quiet case will satisfy you. Slowly though, the noise will creep into your thought. Soon the quietest fan will be loud and the ...

Hi, I am relatively new to this site, but I can definitely attest to the quality of Noiseblocker fans, based on my own experience (although I have to admit I haven't tested any other fans yet - just got into quiet computing). I have a 120 SX1 exhaust fan and a 92 SE2 sitting on a XP-90 HS. They are ...

I thought about cutting out the exhaust grill, but when I stop the fan, I do not hear any difference at all. Maybe the grill creates a little air turbulence, but it is so minimal, that I can't notice it. I don't think that justifies cutting out the grill. Anyhow, I can't bring myself to physically "...

I could only grin as I read Elixers comment. Somehow I am bound to believe him :) Thanks for the tip for hosting pics. Here's my attempt: This is my rig as of my original post: (Notice the cable jungle next to the PSU, I took care of that later) http://img295.imageshack.us/img295/1618/1casebeforesus...

I AM enjoying the quiteness :) And this afternoon I took your advice and suspended my HDD. The difference is unbelievable! Even the search/write/read scratch noise is considerably reduced. Any thoughts of switching to a Samsung p80 are more or less gone. We'll see how fanatic I get :lol: I also remo...

I have the AeroCool VM-101 on a Sapphire Radeon 9600 Pro in a SLK3000B case with the Thermalright XP-90 Heatsink on the CPU. The VM-101 fits very well, plenty of room for airflow, and keeps the card cool.

Hi, Having been a regular lurker since several weeks now, and having taken to heart a lot of the test results and advice in forums, I decided to finally do some work on my PC. My old PC was terribly loud. So loud in fact, that I couldn’t watch TV on my new Hauppauge TV Card without being completely ...
