Hmm good tests. So what would you say the limit is for rpm range until the performance won't get any cooler

Who knows? I think it's asymptotic -- it gets lower and lower more and more slowly, but never quite levels off. What is the mathematical limit? Can't tell.

 

But you can see a practical limit begin to form at 4 - 5c better cooling than stock (TOA = 47 - 46c). Then at 5 - 6c better than stock (TOA = 46 - 45c) it gets really hard, with the practical limit right at 6c better than stock (TOA = 45c).

Interesting review for me, as I just got a D-14. I notice that the Sickleflow's keep it about 3-4c cooler...and well, I ordered two use as side-intake fans...think it would be a smart idea to swap one of the Noctua's 120MM fans and replace it?

48 VS 51 seems to me to be a pretty good difference, considering both fans were already going to be in the case. Would you recommend this? dBa would be the same I imagine.

Yes! more ehume stuff smile.gif reading it all right now biggrin.gif

So yeah, basically, the verdict is, just leave it @ stock.

One more thing. If I was to mail you a pair of Delta PFB1212UHE's, would you find them useful? They're results would serve as an asymptote. We already know they wouldn't be practical, but perhaps they would supply a useful(?) point of reference.

Read through this Chapter 6.  To me, Noctua has done their homework thoroughly.  Their stock configuration is right on the balance point between acoustics and thermal performance.

 

ehume, another great chapter well done! (+rep)

 

Any more chapters to come? 

post #16 of 64
To me this simply proves what I theorized a while ago, that Noctua optimized their cooler designs for lower-speed fans (especially their own; I refer to the very low fin density in relation to other designs), rather than making it better-rounded so higher-speed fans can show off a bit. Good work, ehume.

i noticed that ehume from the graphs and it seemed that way, also confirmed a few hypothesis i had before. has there been a horizontal vs vertical mount comparison yet by any chance around here?

this is very interesting, there is one variation you havent tested though. I'd imagine you can get better performance out of single 38mm fans if you put a shroud in the center to keep the airflow focused thoughout the heatsink, you could possibly destroy a random 140mm fan and hollow out the fan part and use that no?
post #20 of 64
Thread Starter 

I believe I covered the shroud business in an earlier chapter. The best improvement I got was 0.5c. But sometimes a shroud worsened the cooling. I think it has to do with the spread of air from the push fan moving faster when unobstructed. The frame of the shroud may produce islands or a ring of obstruction, and like the bow of a ship cause a reduction of airflow speed in front of the obstruction. So I quit using a shroud.

 

One thing that came out very clearly was when I put my Mechatronics on push, there was a lot of what I call side spill. I could feel lots of airflow on both sides. Then I put one of the Deltas on pull, and there was a lot less side spill. It makes sense of course, but having such a dramatic demonstration was . . . dramatic.

 

Noctua's own fans: Actually I think the TY-140 is a better choice for center fan. Ironically, this may be due to its having wide intake and exhaust flares -- when the 160mm side is installed to make the fan wide rather than tall I got better results.

 

Overall, I think the D14 benefits when the edges of its fins get airflow. When I wrapped up the sides the cooling got worse.

 

I think between Chapters 4, 5 and 6 you can see the tradeoffs between quiet and cooling performance. Chunky is right when he points to the heatsink being optimized for quiet.

 

As for fans, a pair of PFB1212UHE's would get used once or twice on the D14 for testing the extreme datapoint, and then a few times on the upcoming Mugen 2 and the revisit to the Megahalems.

 

Upcoming for the D14 is the PWM testing. I was really hoping I would have some Noctua PWM fans by now.
