What should I say first? The impeccable packaging and build quality as soon as you hold it in your hands? The easy installation even for beginners? Incredibly quiet, as if it doesn't exist! Beast (be careful with the case). The color is a matter of taste. In my build, I only have Noctua with the classic color and it looks beautiful. It's an investment in cooling, guys.

Noctua is the standard by which coolers are measured. In my opinion, it is the second-best air cooling solution on the market, aside from the NH-D15 which has 2 fans. It performs similarly to dual-fan liquid coolers, without the risk of failure or leakage. I am looking forward to its successor, which is rumored to be released in 2022.

In a stress test, it reached 30 degrees above ambient temperature on an i9900K at 4.7GHz.
That's good. (With a fan 2 degrees lower).

One of the most premium! With i7-9700k and its own thermal paste, it reaches about 29-34 degrees idle, in a Sharkoon Pure Steel Black case and with one low-profile Noctua fan. It reaches 47-52 degrees under load when using Photoshop and Autodesk Fusion 360 rendering with Chrome open and multiple tabs running.

It has the performance of a liquid cooling system, costs half the price, and you will have it for a lifetime without any damage.

I wish it was a bit cheaper.

I ordered the NHD15 and they sent me this one. I didn't have the courage to go through the process of sending it back and waiting another 10 days for the right one to arrive. For psychological reasons, I also bought an NF-F12 pwm fan (not that I needed it). So, I gave an extra twenty bucks, but I gained absolute compatibility for any memory and the best cooling you can have without water.
AMD [email protected] in silent mode and the fans at 500-530 RPM only reached over 1000 RPM on Intel burning, but still, you can't hear anything. ONLY NOCTUA guys, THE END

4770k/GTX 1080

It's unbelievable, and if someone told me, I wouldn't believe it. Before, I had installed this particular NOCTUA, a top-of-the-line cooler with a 250W TDP from THERMALTAKE, with TWO 120mm fans configured as intake/exhaust.

The result is 10-13 degrees LOWER than the previous cooler at full OC 4.5 GHz (50-53 C compared to the previous 60-63). It's unbelievable, I can't believe it. Before, I didn't have a crappy cooler, I had the best and most expensive cooler from THERMALTAKE.

The other thing is that my system has become completely silent. Now, I can only hear the PSU fan slightly and the... refrigerator in my house.

And all of this is done by the Austrians with just ONE fan. You pay 80 euros, but you never have to worry again.

I highly recommend it! H TOP air cooling is my personal opinion and experience with this product. It cannot be compared to any other. It is an incredible tool if someone does not want liquid cooling. I use it on an i7-8700k. It keeps the temperature at 25-30 degrees Celsius when idle and 60-65 degrees Celsius during heavy gaming, even with additional software running in the background. All of this with just one fan. Unfortunately, if someone wants a second fan, they have to purchase it separately. It is not included in the packaging, unlike the D15 model.

Love!
Silent quality Noctua.

I have the fan pinned only at 500 RPM!!! (meaning the cooler is running at about 30%) and the Ryzen 2600 in gaming gives me a higher temperature of 49c with a room temperature of 22c.
Needless to say, you simply can't hear anything :)
With these settings, I ran a stress test (Prime95) for 20 minutes and the temperature reached up to 62c!!
I'm writing it again to believe it:
Noctua running at 30% and seeing only 62c in Prime95!!!
What else can I say?
I had years of Corsair liquid cooling but after Noctua, there's no reason to look back.

The only thing you need is the NH-D15s and a case with proper airflow (I have the Corsair Air 740).
And then let the others with liquid cooling complain about broken pumps and strange noises...

Noctua, top quality and performance, identical or even better than my previous H62NZXT liquid cooler and very quiet! Beautiful except for the classic brown fan that can be easily replaced (painting, new frame). Fearlessly take it if it fits in your case!

The Psyctra is truly excellent. On a 4790k during summer, the maximum temperature in an Aida stress test (only FPU) is 80°C. In normal gaming (Witcher, GTA V, etc.), the maximum temperature is 65°C (room temperature is 30-32°C). It loses one star because it only has one fan instead of two, like the NH-D15 (the fan costs an additional 20-25 euros if purchased separately). The clearance for the first PCI-e slot and the RAM is just right. I have it on a micro-ATX motherboard with the GPU in the first slot and HyperX Beast RAM. Everything fits perfectly without any difficulty. The mounting system is truly easy.

The difference with the NH-D15 is that the cooler is slightly offset further away from the graphics card. Compatibility issues are solved this way.
If you want a second fan, simply add it. The mounting clips for a second fan are included in the package.
In terms of cooling performance, it competes with straight liquid cooling systems, with the difference that it produces less noise than liquid cooling systems.
There is nothing better on the market.

I have it for a week (the RESERATOR 3 MAX ZALMAN spit them out after 18 months) and it is, so far, incredible. Completely silent and in idle mode it keeps the i7-4770k at 30 degrees. It is indeed huge but on the company's website there is a compatibility list between different coolers and motherboards. Personally, it's worth the money and I still have to overclock it and see the performance!
