[TPU] Noctua Presents NH-U12A Premium Class 120mm CPU Cooler

Quote:
Noctua today presented its new NH-U12A premium-quality quiet CPU cooler. The NH-U12A is the latest, 5th generation of Noctua's award-winning U12 series of 120mm size coolers. Conceived to push the envelope of the 120mm form factor, it combines two of Noctua's flagship model NF-A12x25 PWM 120mm fans with a completely redesigned heatsink featuring 7 heatpipes and an increased fin surface area for superior heat dissipation. This way, the NH-U12A can rival the performance of many 140mm sized coolers while offering 120mm class case and PCIe compatibility.

NH-U12A is the first air cooler that is exciting in a long while.

It has 7 heatpipes (staggered in the airflow path) and the NF-A12x25 fan , plus it's asymmetrical.

I'm interested in the low RPM performance though : it has 2 NF-A12x25 so it should still perform decently. The fin stack looks to be increased in FPI , there's at least 50 fins.

This will likely dethrone the likes of the Prolimatech Megahalems and Scythe Mugen 5 as strongest 120mm fan coolers. It's 760g without fans and 7 heatpipes and 58mm depth; Megahalems is 790g with 6 heatpipes and 74mm fin stack depth; Mugen 5 has much thicker 85mm fin stack with 6 heatpipes but is around the same weight as well (890g with fan - 140g from 120mm Kaze Flex spec = 750g). There's some other coolers in the 120mm size but they're mostly budget oriented such as the 167mm tall Coolermaster MA610P , 165mm tall Silverstone Argon AR03 (likely press fit fins), or 165mm tall FSP Windale 6 , which opt for direct touch heatpipes and aren't as high performing.

Megahalems for comparison: http://www.silentpcreview.com/article916-page4.html
~47 fins , Fin thickness 0.5mm , 2.0mm fin spacing , 45mm clearance underneath

Mugen 5 is 39 fins, 2.0mm fin spacing and 0.4mm fin thickness


(Also for reference , the 770g NH-U14S has 0.42mm fin thickness and 1.72mm fin spacing : http://www.silentpcreview.com/article1359-page4.html , though if you don't count the low fin area fins there's 51 fins instead of 57)

$100 USD is a tad bit too much, even more expensive than the NH-D15...
could've just went with a single-fan, extra clips and put it up for $70, which would make it just $10 more expensive than the old NH-U12S.

trolling an adult is very dangerous, don't try it at home nor at work. you don't want to play tag with a rabid man.

Sadly $150+ cad for this. My corsair H150 Pro was $165

Just installed a Grand Macho RT in my M-ATX rig, it was a pretty tight fit but I think I'll be okay. This still looks very nice and the NF-A12x25 fans are nice offering - I use those on my 1080Ti and they keep it under 75 celcius at 2075 MHz without getting noisy.

I'm replacing a corsair H150 Pro with this. I can't stand the setup atm in my corsair 1000D. It's uneven with a single 360 rad would rather have my 8 Typhons up there all nice and flush. Then 3 140s in front and 2 more Typhons in back.

You seem to be forgetting the Scythe Fuma, which uses 120mm fans, and defeats the Mugen and almost keeps up with a D15.

Forever a WIP.

Width wise, air coolers come pretty close on the big ones to touching cards in the top PCI-E slot. This most likely means it still doesnt cover that slot area. Not that it matters much since most motherboards do not locate a 16x slot at the top, but rather a 1x slot and then a 16x. So spacing for most boards is fine even if it were to cover slot 1
