Noctua shows off 1.5kg fanless cooler that can handle high-end processors

Noctua’s line appears more than once in our ‘Best Cooling’ feature, including the much-loved NH-D15 as the ‘Best Air Cooler.’ The company revealed its next-gen successors to that model in Taiwan, which have 10 percent more surface area and seven instead of six heatpipes to improve performance. There’s also a dual-fan version designed to handle high-TDP CPUs.

The big draw was Noctua’s ‘Fanless CPU Cooler,’ as it’s currently called. The 1.5kg heatsink features a copper base, 1.5mm aluminum fins, and six heatpipes. Despite being passive, it has a performance target of 120W in a fanless case, though Noctua claims this can be increased to 180W by adding a 300rpm fan. We don't know the physical dimensions, but it does use an asymmetric design for better PCIe clearance and is 100 percent RAM compatible on LGA115x and AM4 motherboards.

To show off the fanless cooler’s capabilities, Noctua was testing it using Intel’s consumer flagship Core i9-9900K—an eight-core chip that can reach 5GHz and has a TDP of 95W. PC Mag writes that despite the test taking place “in the hot conditions of the Computex show floor for several hours," it ran at 95 degrees throughout.

While Noctua's prototype is a beast, there have been heavier coolers, such as Thermalright's near-2kg True Copper passive heatsink.

No word on its price or when a final product will launch beyond an ETA of 2020, but it will ship with some NT-HZ thermal compound in the box.

I've been using old big heatsink for my soldering iron parking spot. I figure, if you put large enough heatsink, it will dissipate enought heat for the source.

95 is unacceptable to me, even if it was on a show floor. I suppose if you need absolute silence this could be a solution, but I'm not terribly impressed otherwise. It also looks enormous and heavy and will likely not be cheap.

I'll stick to closed loop.

95 degrees at what stable frequency? That seems like a limit temperature for thermal algorithms, so surely it was a sustained frequency between base and turbo, but just how high I wonder. Remember the TDP with Intel only applies to base frequency operation.

The one benefit of it being fanless is you don't have to use their fans with their terrible colour.

That's really a waste of metals nowdays there is a lot of high quality fans that gives you near silent decibels with a fraction of the price for this huge mammoth of a cooler , unless you're going to use your 9900k in a case 100 percent closed with 0 airflow

If you do, please post pictures and show your temperatures. Although maybe not when you have the heating on.
I wonder, if I connected a hose to my computer from my home radiator during summer...when it has a virtually endless amount of water to heat up, what would happen.
