NB M12-S3HS Fans Anyone?

post #1 of 13
Thread Starter 

From what I've read here on these fans (not a whole lot), they are VERY good rad fans. But if they are as good or better (per the few that own them) than the legendary "sold-out-everywhere" GT's, for $5-$7 more, why aren't these talked about more here? I'd rather spend the extra $5 now, then have to wonder when the GT's will come back in stock.

From what I'm gathering, they run true to their spec's of 2.8xxx static pressure, @ 27db (about 5db quieter than the GT AP-15 - from Martins' fan thread) and push about ~20 more CFM - though from what I understand about rad fans, it's mostly about the static pressure, not CFM.

YT Videos:





Just seeking a little help to make sure I don't go out and waste $45 on two fans. I respect the other ultra-mega high SP fans, but I value noise over a couple degree C difference. And since I don't have a huge or thick rad, I think I will be fine with a 25mm thick fan. (FYI I do plan on eventually getting the Rasa kit or similar build, so would these (NB) or similar in-stock fans do well on the Rasa/similar [low-rpm rad]?)

FWIW, I own a Coolit ECO (similar/a few degrees better than H50) - paid $62 from Newegg. Had I known about the Rasa kit from Frozencpu, I would have ordered that, but I didn't.



Thanks for your time..


EDIT: In the YT videos, the device next to the volt meter measures dB?

I stopped pondering why a long time ago . They may not be the quietest, or spec the best static numbers, or even flow the greatest. But what the M12-S3HS does have is undeniable build quality, including factory sleeved wiring, a small center hub, silicone edge mounts with a silicone fan silencer and an excellent six-year warranty. About all that is missing from the M12-S3HS is an accompanying three to four pin adapter.

It may be early A.M. symptoms for me, but what did you stop pondering?

If the NB is around/slightly above the GT, has better build quality and is available right now, for a mere $5 per fan, I can't loose. However I am still unsure about the static pressure-to-noise ratio for this fan. And this forum is massive, with tons of folks, and just a couple who own/tried them. Just seems if these were/are that good, there would be a lot more discussion on these.

I say closer to $7 more per, which essentially equates to just over a 40% premium.

I've got two NoiseBlocker M12-S2's on my H70 and absolutely love them. Dead quiet and move plenty of air considering they're inaudible @ 4-5 feet.

Problem is, price. I got mine at KoolerTek @ $22.79 each. Which quite frankly is pretty darn expensive for fans. Granted, they're worth every penny, but still, the price can be a turn off considering the AP-15's can be grabber anywhere from $15-18 when available and perform almost as well at low RPM's.

At low RPM's, the Noiseblockers are really the best overall it seems by all the reviews I've read. Though, once you pass the 1600RPM mark, that's where the AP-15's shine and just start dominating without increasing their noise level that much. Granted, they're still louder than the Noiseblockers, but then again, "loudness" is extremely perspective depending on the person.

Diff between the M12-SH3 vs. M12-P (connected via Molex to the PSU)?

M12-P > H70 > M12-SH3 (Intake) all of last week:
OC to 4.214 GHz @ 1.475v w/ CPU-NB 2800 MHz @ 1.25v = 37C idle @ 65F ambient

M12-P > H70 > M12-P (Intake) for the past three days:
OC to 4.214 GHz @ 1.475v w/ CPU-NB 2800 MHz @ 1.25v = 35C idle @ 65F ambient

Chalk it up to a higher static and/or slightly greater flow, either way the idle diff is a bona fide 2C on a decent OC where I sit. Have to sift through my accumulated load numbers, though I gather the diff will reflect similarly.

Thanks guys. I see why people could shy away from these, being a few dollars more than the GT's, however I am not paying S&H @ SVC for these, which in its self, saves $5, unless you find a site that has them in stock, and has free S&H. Even if you were to order 2 or 3 GT's, most places require you to pay S&H.



Also - Adam - any idea how the PWM version is ~2c cooler? Same stats, correct?

SVC is a great shop to deal with. Fast shipping, excellent prices when you factor in their free shipping policy. Considered their top-of-the-line 120mm x 25mm offering, the M12-P has a higher rated static, flow rate and peak RPM than its MH12-SH3 brethren. Note: Do not fall into the mindset that the M12-P is a silent fan at full speed. Quite the contrary, they are absolutely audible from a distance, even from within my case lined in part with with AcoustiPack 7mm sheets. Also keep in mind that the NB M12-SH3 undervolts very well .

The NB PL-2 using an A-weighted meter actually does top notch at really slow speeds, it just didn't do that well at 12V. I like the frame design...

Wow, these fans are EXCELLENT quality fans. It's already been mentioned the excellent build quality - that's no joke. These are wonderfully built. The cable sleeving is excellent as well.

They push a lot of air, during my quick test - just plugging it in @ 100%. SUPER quiet.

Later today I will install onto my rad.
