Rank #1 in Best CPU Air Cooler 2026: 10 Ranked, One Sold Twice at Two Prices
Noctua NH-D15 Dual Tower CPU Cooler
Price and rating as shown on Amazon when we collected them. Both change.
The Noctua NH-D15 is the air cooler sitting at number one in this guide: a dual-tower design with six heatpipes and two NF-A15 140 mm PWM fans, listed at £99.95 with 4.8 out of 5 from 11,307 ratings. Noctua calls it the successor to the NH-D14 and cites more than 250 awards and recommendations from hardware sites and magazines, a six-year manufacturer's warranty, NT-H1 thermal paste in the box, and SecuFirm2 mounting for Intel LGA1851, LGA1700, LGA1200 and LGA115x plus AMD AM5 and AM4, with an offset mounting option.
The number worth reading twice on this ficha is the Wattage field: 1.56 watts, listed next to a 12 Volt, 4-pin fan connector. That is a fan-sized power figure rather than a cooling capacity, which makes it the mirror image of the pattern we flag elsewhere in this guide, where a 'Wattage' cell carries a 250 W or 265 W thermal number. It is also worth noting what the listing never states: there is no TDP or processor wattage rating anywhere in the specifications. The height figures do not agree with each other either — the dimension field gives 16.5 cm high, while the item highlight on the same listing says 168 mm, which is 16.8 cm. Everything on this page is taken from the Amazon listing; none of it comes from testing we have carried out ourselves.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I got this to replace a Corsair H80i on my old fx8350. That's an AM3 socket. I sent Noctua proff of purchase and they sent me the correct bracket, for free, same day despatch. Terrific and unique service.The cooler itself is their usual quality and will keep my old processor cool enough even when overclocked - I run it at 4.6ghz, which consumes around 220watts!Of course you need a big case to hold it, but I have that and I checked on the Noctua website that my old motherboard was compatible - they still have the lists.”
Verified purchase“Keeps my i7-13700k cool. I've tweaked the BIOS and the fan only comes on if I start working the CPU hard, at which point my PC fans are quite loud. But that's fine, I can feel the heat blasting out. Most of the time it's 0dB, ( at least to my old crappy ears right up close).One thing to check. I could only mount one of the fans on the cooler, the other one blocked by something (memory sticks? I can't remember). Anyway, if you really need the second fan check it will fit as they are larger than normal fans and will be closer to the MB.”
