We are getting a fair amount of “big heatsink” options for enthusiasts, which is nice. This one is from a Japanese manufacturer, Scythe Co., and it's quite big. It is similar in size and weight to the Noctua D14, but in a four-tower design. Each stack of fins has three heat pipes, twelve fingers total, to deliver the heat up from the plate that rests on your CPU. It measures 13cm x 15.5cm x 15.3cm and weighs 0.9kg.
The product page doesn't seem to declare a fanless operation mode, but FanlessTech mentions that previous models were advertised at, not just abused by enthusiasts to, 65W in passive configurations. It is a pretty large cooler, so that makes sense. I have also seen a few posts where the Noctua D14 can be used fanless for around 65W. You cannot really make an apples-to-apples comparison between the two units though. While the size and weight are similar, the geometry is quite different. For example, the Noctua is really designed to have fans installed between the two towers as well as the ends, blowing air over the fins in a certain direction.
No news about pricing or availability for Europe or North America yet. The company does have an international presence though.
Are there any semi-passive
Are there any semi-passive CPU coolers? I want silence when I work but performance when I play games.
And I don’t want to fiddle
And I don’t want to fiddle with software. It should just work out of the box like new geforce 970 custom design coolers.
So like, with a 0% fan
So like, with a 0% fan profile under X conditions? Hmm. Not sure for the CPU. I know they exist for PSUs and, as you said, seom GPUs. I'll ask Morry.
