The Noctua NH 15 is a great air cooler one of the best air coolers actually. What are you pairing it to? What CPU?

Almost all things noctua are good. However. They are expensive and if you’re not plotting on future cpu high TDP chips it’s overkill. I don’t honestly see the need to drop that much money on a CPU cooler. There’s near equal more cost effective options. Unless your doing major overclocks, cpu heavy loads at near max clock speed constantly where you think major wear and tear will happen I don’t for see the need to spend that much. I’ve built many many PCs.

You can find comparable air coolers much cheaper. Think 50 to 80 range and technically you can score them on eBay for cheaper than that. Look at the Phantom spirit 120 cheapest 30 to 40 usd, AK620 1 to 3c cooler than phantom 50 to 65usd, frost commander 140 80usd, noctua DH 15 150 to 180usd.

Of course prices fluctuate. Those get you the best ranked air coolers for the most part. Their all within roughly 5C of each other. All good coolers. Take the extra money savings and add to a GPU or whatever part you really need.
