Noctua NF-F12 iPPC-3000 PWM vs Corsair SP120 PWM on Antminer S5

[lex_minutor]

After reading about the SP120 on the Antminer S5 thread I decided to give it a shot.
Tested fans:
Noctua NF-F12 iPPC-3000 PWM 3000rpm - http://www.noctua.at/main.php?show=productview&products_id=80&lng=en
Corsair SP120 PWM 2350rpm max - http://www.corsair.com/it-it/air-series-sp120-pwm-high-performance-edition-high-static-pressure-fan-twin-pack

The NF-F12 is about 50% more expensive than the SP120, $16 vs $24 each (prices from amazon)

All the tests were done on the same Antminer S5 using the same default 350M frequency.
The room was at a constant 65F and each run involved powering down the S5 then running it for 15 minutes before getting results.

Using 2 NF-F12s in push/pull configuration:
49C/51C | 1800rpm/1920rpm

Using 1 NF-F12 as push fan:
50C/54C | 1920rpm

Using 1 SP120 as push fan and 1 NF-F12 as pull fan:
55C/57C | 1680rpm/2280rpm

Using 2 SP120s in push/pull configuration:
59C/62C | 1800rpm/2040rpm

I will remark that the NF-F12s are about 5db louder at 1 foot distance but in the end I will stick with the NF-F12s since they provide better cooling.
The SP120s may be better when used on a heatsink but I think the high static pressure may not do as much good over the 10in of heatsink on the S5.
In the end the 110CFM of the NF-F12 won out over 63CFM of the SP120
Let me know if you have any questions.

Noctua is much expensive but is greater from any other fan out there. Imo noctua has the best fans and is far away better from crosair

They're 2 fans at different performance points used for different purposes - I'm not sure how you can can compare entire brands' of products based on that.

[chek2fire]

I have use many of them in my desktops for many years now. in my opinion the noctua fan is the most silent of all of them.

[dogie]

Hmm I think the S5 and the S4 use the same fans, I wonder how these would work on the S4.

Yes they do, and possibly in a lower ambient setting. S5s have different cooling changes to S4s which use a brute force approach so its pushing it.

So the NF-F12 Is 109CF

This fan is 119 at max: http://www.newegg.com/Product/Product.aspx?Item=N82E16835553002

and still seems pretty silent, any reason why this wouldn't work also?

Sorry I was talking about the Antminer Fans for S4 and S5, I should have posted this in the thread.(Didn't mean to pm you dogie)

One thing that isn't obvious is that the fans for the S5 and the SP20 seems to require a fair amount of static pressure to get the actual colling effect. The CFM (volume of air moved) isn't the only consideration as I understand it. You might find a higher CFM doesn't actually yield the result you expect, because it doesn't have a high enough static pressure.

Can you give us figures of actual db from the miner, especially compared to stock? i know some reviewers were saying at 4 ft, stock fans on the S5 are around 75 db. i'm very interested since I have my 2 s5's and an s3 set up in an office where the noise is just unbearable

I did use Noctua in push and Scythe Ultra kaze in pull. Two Noctuas/miner are expensive.
Both together gave ~55 dB vs 73-75dB for stock at default speed. It was still a little annoying in the office, but totally fine in another room.

if anybody wants, I have two Delta AFB1212SH-PWM fans which i don't really need since I sold my S5s
These seem to have similar(if not better) air pressure and CFM to Noctua and they are less expensive (advertized as 46 dB, but typically i don't believe these claims)

Did you power the noctuas from the s5 mainboard?

Did you power the noctuas from the s5 mainboard?

Yes, I did (if you mean on the controller in the middle). One small rail on the connector is in the way, so I clipped it off.

[jstefanop]

Any reason why these wouldn't work?

They push 90 CFM at 2k RPM

[Minerkev]

Put on the noctuas today....they are quiter than original....did push/pull
Temp now is 67 and 65c with the original i never got over 52c....so will return them to seller i guess

151 cfm delta as a push and a  silverstone 141  does 170 cfm as a pull   this works.  link for the silverstone

the delta

there is a better push  then the delta , but I am tired and not feel like looking around my post lists for it.

this may be it

If we change the fan, does our miner get out of guarantee?

[gablay12]

Did you power the noctuas from the s5 mainboard?

Yes, I did (if you mean on the controller in the middle). One small rail on the connector is in the way, so I clipped it off.

I have Noctua NF-F12 IndustrialPPC - 3000 PWM , mine does not work with the 4 pin rail (where the original fan was connected).
Is there a reason for not working?Do I need to make a modification?I power the fan from the PSU.

few things:
1. if you are powering the fan from the PSU (through molex adapter), then why are you talking about 4 pin connector on the miner?
2. in order to properly fit Noctuas connector to the 4 pin connector on S5 controller, you would need to clip a small black ridge on Noctua connector with a nail clipper or something like this, otherwise the plastic side on S5 connector is bent and the connection is not good. Make sure that you are connecting it in proper orientation and engage all pins.
3. Also noctua is very silent on low speeds, so you have to look carefully if blades are moving. It could take a few seconds after you restart the miner for blades to start rotating.

1.I have no problem with the fan when powered by the PSU.
2.I will search for the bridge.
3.No,it is dead silent.It is not working.The industrial fan is not so silent.

bridge? something is lost in translation
you just need to clip off or file off the small bump/ridge in the middle of noctua connector (no bridge is required), then connect to s5 in proper orientation.
in addition-do you have the 4 pin pwm connector on your noctua? if you have 3 pin instead, then it would not work on the S5 controller.

Noctua NF-F12 iPPC-3000 PWM 3000rpm seems to be good one as per your result, and i think it's noise a bit less then originally attached fan with s5.

[zagamon]

Here is my two pennies worth on the subject.

I did buy a single (just push) Noctua NF-F12 iPPC-3000 to see just how well it would perform compared to the original jet engine.
Even at full speed (2780 rpm) it could not cool the miner properly at 26 C room temperature. It would keep the miner at a constant of
63 degrees Celsius. About the same performance as the original at 35% fan speed. But the noise of the original at 35% is lower (and somewhat duller)
than the noise Noctua NF-F12 iPPC-3000 produces at full speed. Based on this experience alone, I would be hesitant to call the Noctua NF-F12 iPPC-3000
an upgrade.
