NOCTUA NF-P14s redux 1200 vs NOCTUA NF-P14s 900 redux

post #1 of 31
Thread Starter 
Hi guys i was wondering which i should get out of the two for my cpu case.

1) http://www.noctua.at/main.php?show=productview&products_id=88&lng=en 1200 RPM

2) http://www.noctua.at/main.php?show=productview&products_id=89&lng=en 900 RPM

1200 rpm one is rated at 19.6 db while 900 one at 13,2 dB. 1200 rpm one has 30% more airflow.

Basically question how loud will my case be if i get 4 of them, all kinda hooked directly to PSU w no controller. I'd like to get a decent airflow in my case since its inside desk table so case got almost no breathing room on sides but front and back are good, with top only having about 5-6 cm of space before it reaches wood.

My CPU fan is rated at 26db, and graphic card will be probably MSI R9 390. Basically question is how loud will they be? My current case has few 22 DB rated ones and its not rly that bad, but the case has only 3 fans vs what will now be 6 (2 already come w the case).

I'm planning to have 2 at front, 1 on back, 2 on top and 1 on bottom. Case comes with 1x front and 1x rear fan , should i replace rear one with one of noctua ones since its probably quite better than the stock, and move stock to like top slot?

Thanks smile.gif

Fan rated dBA is bull pucky. If it is accurate, it is the noise the fan makes setting out in the open with no resistance.
Fan will be louder when pulling air through case grill, filter, etc... and they all also contribute to the noise level.

That said, give us all the the info. We need to know what case, mobo, CPU cooler, etc.

Your case is setting with no side, clearance and 60cm isn't a lot on top. Is the back of your desk open so air out the back has somewhere to go?

i'm planning to order Corsair 300r because it one of the few that fits the desk and has the specs i need. Afaik its not rly quiet but i don't really have a lot of better options at the retailer i wanna shop at. I'm moving to this case because i wanted to upgrade my old 5770 to R9 390 but it woudn't fit my case. So the stuff that i'm moving into it should be as following:

CPU: I7 930

Motherboard: ASUS P6T SE

Cooler: Scythe Kabuto

Ram: DDR3 12gb Corsair 1600mhz CL dominator

PSU: TX 650w Corsair

Graphics: R9 390 MSI

Case: Corsair 300r

and 3 HDs, 1 SSD, 1 BD rom

And its 6cm only on top. The back is open because its desk on wheels so i can move it form the wall 50cm or whatever i want kinda, its just the box where case is supposed fit is quite small and doesn't allow a ton of ventilation.

Corsair 399r .confused.gif
Do you mean 400R?

I know its medium range case at best...only one that can fit 17cm CPU fan + large VGA.. i plan to upgrade my cpu and cooler in like 2 yrs so i want to have space for decent noctua and they are usually 16.5cm high...

And i need the desk on wheels because i like to drag cpu closer to bed so i can watch stuff on 26'' before sleep..normally i would just get a bigger and sound proof case and let it rest next to desk on floor in open space

edit: lol didn't notice 399 typo haha..did mention 300 in first line of text but screwed up info..sry about that smile.gif

4 140mm fans with no controller? NF-P14s 900 redux. 4X of the 1200 rpm version will be too loud. Unless you're gaming with phones or speakers cranked up.

Why no fan controller? Budget? Electron freedom principles? Lots of controller options that aren't too costly. What are your placement plans for the 4 fans? Intake and side? Or? How do you know you need 4X 140mm fans?

What that black cat said.

Most mobos can control case fans. I prefer using PWM fans, but variable voltage work too. You might find "Ways to Better Cooling" thread linked in my sig of interest. 1st post is index, click on topics of interest to see them.

Yes i've actually read your guide twice last night but was quite tired, will go to through it again and take cliffs. I cannot believe they refined cpu building to this extend, before it was just about slapping parts together and voila. I used to build cpus a lot more before like every 2-3 yrs but now i've slowed down quite a bit and didn't even build my current one due to RMA requirements so seems i'm outdated quite a bit.

Now when i look at it, seems old retailer did such poor job w wiring and stuff inside cpu and it was kinda best i could get given my location.

Actually PWM fans cost exactly the same as the normal ones, i can even get the 1500 redux version if i want for 30c more per fan. These are rated at 25.8 db so its quite a bit more sound than 1200 version but then again...i mean i was playing around with Fan Xpert yesterday and noticed that at full load only sound that i hear from my motherboard is the CPU fan, when i set the fan at 20%(which is too low for it to even be at idle at good temperatures, but i will re-seat/ reapply thermal paste when 300r comes) my cpu went almost full quiet, i could barely hear it being on vs when it hit 1300rpm(its max) which is rated at 26.8 DB. When i had it at 20%, the fan that is at 100% @ 22.8db at back side of case was barely noticeable.

I mean my hearing is fine, i can hear stuff that most ppl cant in CS GO etc but i've lived in heavily AC-ed regions of the world for a while so maybe my brain is a bit deaf to fan sounds so i got a lot bigger tolerance lol.

I'll take pictures of case location in the cpu desk, and try to google a good 300r setup which should closely reflect mine and then draw the fan locations i plan to use and this should give you a better idea of the layout.

I've also found specs on the stock fans

140mm Corsair A1425L12S (Stock intake)
1000 RPM +/- 20% 54.0 CFM 20dBA 0.30A 3 pin

120mm Corsair A1225M12S (Stock exhaust)
1200 RPM +/- 10% 32.95 CFM 18dBA .11+/- .02A 3 pin


Seem like cheap 4e fans

My only concern is given in live in Croatia, a lot of online retailers don't ship here, or at like 20 30e shipping costs. Finding Mini 4-Pin GPU might be a bit hard, ill see and get back to you, I've found the other one quite easily, will have to go through land based retailers websites xD

Another option for the GPU PWM is find a dead GPU or GPU fan and use the connectors and wires off of it. Just splice them into a PWM splitter as needed. Or on your GPU wires just add / splice PWM leads / wires in from PWM splitter.

Oh! Not to correct your use of English language, but "CPU" is not a computer. "CPU" is the processor we put on motherboard and put our CPU cooler on. wink.gif

Edit: The stock Corsair fans are not all that good. Try them and if they do the job fine, but I'm not impressed with Corsair in general.

What if i only use this? http://www.akasa.com.tw/update.php?tpl=product/product.detail.tpl&no=181&type=Cables&type_sub=Fan%20Cable%20Adapters&model=AK-CBFA03-45

Its only one i could find after looking quite a while...i could just hook up 4 case fans + cpu on that and set it so when I'm at multimedia browsing (like <15% load) to be just working quiet while keeping cpu under like 55c or smtn, then when i turn on games i assume this would spike up so i could have 2nd setting for load between 20-50%, where fans start to work at like 60 70%, like cpu 55-70c range and then 3rd setting for when cpu hits 70c when its either doing actual work at 100% load or CPU intensive game. Obv i would adjust these when i would see actual temps in real life use, so these are just arbitrary.

I'm not really looking to OC the 390 to max, only a bit so i wont be pushing it to the edge really (nor does my current PSU allow it xd) so perhaps GPU PWM not really that important

I'd just leave GPU as it is to fight on its own, the extra airflow it would get should be more than sufficient. If i find that its getting too high, i could just bump up the settings a bit on the cpu.


As always thanks for help and clearing up the CPU vs computer issue..i'm aware of that but its a bad habbit i've picked up as kid and i can't get rid of it lol. Will work on that xD
