Cooler Master H411R and H412R squeeze four heatpipes into tiny towers

There are a huge number of factors that influence heatsink performance, but one of the most obvious for tower coolers is the number of heat pipes they use. That could be the reason that Cooler Master's latest Hyper H411R and Hyper H412R 92-mm tower coolers have four copper thermosiphons, up from three in the preceding Hyper 103. The new units are fundamentally the same; your choice of model simply determines whether you get a white-LED-equipped fan or one with no lights at all.

Most enthusiasts probably prefer 120-mm coolers like the Hyper 212, but shrinking the spinner allows for a shorter cooler. The name of the game for the Hyper H411R and Hyper H412R is a small size with big performance. While we wouldn't venture to call these coolers "low profile," the new heatsinks are just under 5½ inches tall (13.6 cm). Since they're under six inches tall, they'll fit in cases that the taller 120-mm coolers won't.

The four-pipe configuration is very similar to the company's ubiquitous Hyper 212. However, the heatpipes on this model are set into an aluminum base rather than being smushed together to create the entire baseplate of the heatsink. Whether this will actually have any effect on the heatsink's performance is difficult to say. The boxy fin-stack on the Hyper H411R and Hyper H412R does offer slightly more cooling surface area than the angled backside of the Hyper 103.

Cooler Master hasn't announced pricing or availability for the new heatsinks. The company does call them "affordable," so we'd expect them to go for well south of $50.

    My biggest gripe with the 103 (and why I don’t buy it anymore) is because the plastic fan clips are exceedingly brittle, yet you need to remove them to install the cooler in some configurations.

    I’ve thrown a couple away before because they caught me out and were not worth the return shipping to RMA.

    It’s better to just spend more money or buy products that don’t have obvious design flaws. A wire clip would work better, otherwise CM shouldn’t use such brittle plastic is something that is a [i<]spring[/i<] clip.

    I had to use a Cooler Master TX3 in my old Frankenstein’d desktop for this very reason- I couldn’t fit a 120mm cooler in the (not exactly tiny!) case I had. It was still a hell of a lot better than the crummy stock fan, and a worthwhile upgrade. Glad that this market segment isn’t getting neglected!

      Indeed. I actually liked the TX3 for the push-pins. If you’re assembling lots of machines, push pins are a welcome change.

      People hate on them, but for smaller and lighter coolers they’re more than adequate as long as you understand how they work. I think the haters fail to install them properly and then blame their lack of care on the pins when they’re a pretty solid design that requires no assembly or access to the back of the board.

        Yeah, push-pins are fine for non-massive coolers. My Zalman CNPS5X survived multiple reinstallations over 4 years, alas I stepped on it last week when I was installing my CLC and broke the fan hub. RIP.

    Spinning the market with smaller RGB market turbulence.
