Fan review: Noctua, Corsair, Gentle Typhoon

[bracka]

It doesn't have a readout, but according to the box it'll take them "as low as 40%"  so I'd assume they're around ~580 rpm? give or take a couple RPM.

 

I know I didn't have any professional equipment to make a completely professional-type video, but it is quite a difference in noise levels comparing the two.  And the 40% to 100% on the GT's is noticeable but not nearly as bad as the nf-f12's from 40 to 100, I love the in-audibleness of my gt's and 90% of the time they're ran at 40%, I only put em at 100% if mining/ benchmarking.

Could you stick the Noctua into motherboard port and set it to 40% using something like speed fan. Then compare the noise with 40% on your controller. Thing is the Noctua doesn't sound like it should @ 40%

I have a theory regarding your results, but I am not completely sure - so don't want to post it yet. Basically I would like you to compare those fans when you are sure they are running at equal RPM.

I can do that in a while yeah, I'll have to re-install asus ai suite, even though it's terribly glitched and buggy

Can't you use this?

I use it for setting a manual curve for my fans. It is a little difficult to configure correctly though

oh crap, didn't even realize thats what it was, I'll download and try it out, thanks!

 

I'll test and see what it's like. I'm also trying to figure out wtf is wrong with my fire-strike benchmark

[Lays]

@bracka where on earth do I go to change the fan curve? I don't see it I'm blind

[TheProfosist]

They're coming out with a newer and better version.

The grand kaze's? If so yes they are their replacement but their a completely different style fan so well really have to see how they stack up.

[bracka]

Did some quick napkin math (in excel)

Depending on fan's resistance the same 40% on fan speed controller (depending on implementation) might provide different amount of voltage to the fan. 

Here is the math for serial circut with varying resistance R1 and different fans R2, R3, R4

Please, let me know if i have made errors

I recently made a video about 1450rpm gentle typhoons vs noctuas, check it out if you like:

 

 

Are the Noctua and Scythe fans blowing in the same direction?

 

Any chance one of the fans in the case could be tested outside a case like the Noctua?

The noctua was actually running faster than 40%, due to the resistances of the fans being different @bracka helped me on skype set up speed fan, and explained that maybe the resistances were different..   I re-tested with them on my motherboard at 40%, and they are a bit quieter, still audible at 40%. The 100% isn't effected by this so they're  still very loud at 100%.  And yeah, as you can see from the video they were in the same direction.  I'll make a new re-work of the video with one outside the case when I can be bothered to rip my fans off my radiator, it's a big PITA to get them back on .

 

I will for sure make another video, with all my fans off and my HDD unplugged, and a towel under my door to try and isolate as much noise as possible and re-test.   Then I'll test each fan individually, with speed fan. I'll also record my webcam as well as my screen whilst doing it, so you can see the results.

Excellent. I hope a short bit establishing ambient noise level before each test could be included. Of course that begs the question of how one might account for other system noise.

"in theory" that should get rid of other system noise, I have my pump on it's lowest setting so it shouldn't make noise.   Just finished painting almost my whole room  gotta wait til it dries then finish the little spots with a brush

 

 

I should be able to test this weekend-ish

[flibberdipper]

Does anyone has suggestion for a fan that would perform extraordinary well on a heatsink/case ventilation duty? Preferably with PWM capability. Might test a few more this spring

BitFenix Spectre Pros?

[Cobus]

Well done @bracka

 

I am so glad someone finally made this type of comparison video about aftermarket fans
