Great Cooler 7/20/2020 4:00:31 PM

Pros: Successfully keeping an I7-10700K chip operating at 4800 with burst into 4950 MHZ in a Stock Fractal Design Meshify S2 case (2 140 in front and 1 240 in back). Fairly easy to install. I really wanted the NH15 but was not sure of the memory clearance plus weight on MB in a vertical case. Have dome some gamming in Death Shards that came with RTX 2070 Super and CPU temps did not exceed 56 C.

Cons: I did have minor difficulty getting the heatsink to screw into the secure firm brackets. I ended up doing several practice runs before putting on the thermal paste. What ended up working best for me was to practice setting the NH-U12S on the two secure firm posts and then using both hands tightening down both sides at the same time while applying downward pressure. After 4 successful tries in a row, I put and small amount of the thermal paste on the CPU and went for it.

Overall Review: Great cooler be sure to practice installing before putting thermal paste on.

Don't judge a book by it's cover 7/12/2020 1:52:12 PM

Pros: I was dumb and bought a pre-built PC from Best-Buy. The tower it came with was only good at trapping hot air in the PC, causing it to overheat CONSTANTLY. I bought this along side one of the Fractal towers and already I'm seeing a HUGE dip in temps, from an average 50-75 c to 25-35 c while idle/using chrome.
The kit comes with most of the things you need to assemble it, having thermal paste was also a nice touch. The only trouble I had with it had everything to do with the design of my motherboard (Pre-built PC problems), not the Cooler, but I managed to resolve it with some tinkering.
This thing is also really quite, so quite I thought I did something wrong when I booted up my PC.

Cons: Ugly, no fancy lights, but I'll take performance over looks any day. My wife thinks it's enduring, almost vintage looking. This PC is already a Frankenstein mess anyways...

Overall Review: Would recommend. Sorry if this review isn't informative enough, I'm just really happy with what I got.

Easiest AM4 install ever, great temps 7/8/2020 5:55:26 PM

Pros: * I didn't even need to take the motherboard out of the case.
* Secufirm AM4 bracket is very easy to install perfectly. AM4 bracket now comes with the standard NH-U12S (you don't need to buy the SE-AM4 version)
* Great temperatures with Zen 2 Ryzen 5 3600
* Quieter than stock cooler, especially at load

Overall Review: This was a painless, quick upgrade from the stock cooler that yielded much better temps immediately.

Fit perfectly in a Cooler Master Masterbox Q300L case. Plenty of clearance to RAM slots on Asrock B450M Steel Legend motherboard even with fan attached.

Highly recommended!

Now that's an effective air cooler! 7/3/2020 8:17:24 AM

Pros: - Easy installation will all the necessary brackets
- RAM clearance (even for the nearest DRAM slot)
- Case clearance (I have a NZXT H510 Elite case) with stock heatsink. If you add the Noctua heat sheild, not a problem.
- Knocks down the CPU temps by a good amount of degrees!

Cons: - The famous brown colored fan! Some love it, some hate it. To each their own.

Overall Review: What can I say, this cooler and especially the ones designed and manufactured by Noctua are absolutely exceptional when it comes to performance and quality. Just to give a quick comparison, I recently replaced by stock AMD Wraith Stealth cooler and here are some quick CPU thermals to take with a grain of "paste". Ha!

AMD Wraith Stealth
Idle - 47 Celsius min
Load - 81 Celsius max (running Unigine Heaven at ULTRA 1080p)

Noctua NH-U12S
Idle - 38 Celsius min
Load - 64 Celsius max (running Unigine Heaven at ULTRA 1080p)

Enough said. Thank you Noctua!

Excellent Cooling Fan 6/27/2020 10:49:52 AM

Pros: Super Quiet
Easy to install
Easy instructions

Cons: None

Overall Review: Very quiet and easy to install. Comes with all quality hardware, brackets and thermal adhesive needed. Just use care not to torque down the fan to the motherboard bracket more than necessary. Way better than stock coolers. This cooler is keeping my I7, 3.8Ghz 10700K idling at 28 degrees C and around 75 degrees C under a full load.
