Akasa today introduced the ALUCIA H4A, a low-profile air-type CPU cooler for AMD sockets AM5 and AM4. With its fan in place, the cooler has a Z-height of just under 30 mm, which it achieves using a highly compacted fin-stack heatsink, and a thin form-factor fan. The cooler can deal with AMD Ryzen processors with TDP of up to 95 W, which should make it fit for the majority of processor- and APU models. Its design involves a nickel-plated copper base located between a factory-fitted retention-module. From this base, four 6 mm-thick copper heatpipes pass through, conveying heat to an aluminium fin-stack heatsink, which is ventilated by a 92 mm fan.

The Akasa ALUCIA H4A measures 94 mm x 94 mm x 29.5 mm (WxDxH), weighing 232 g. Its 92 mm ball-bearing fan is rated for 40,000 hours by its designers. It takes in 4-pin PWM input, and turns at speeds ranging between 800-3,600 RPM. It pushes a maximum of 40 CFM of airflow, at 2.2 mm H₂O static pressure, and noise ranging between 17-35.8 dBA. The company didn't reveal pricing, but mentioned that the cooler is backed by a 2-year warranty.

I'd be wary of that "up to 95 W TDP" designation. I highly doubt that such a low-material (low surface area) cooler can cool any "X" Zen 4 CPU.

Personally, I'd only recommend it for the 7600, 7700 or 7900, and nothing else.
 
There was a time when this would have been considered overkill (because of the heat pipes).
 
What situations require a height of < 30mm? The only thing that springs to mind is a 1U rack chassis, but then you can't use coolers that intake from the top because that's basically in direct contact with the lid of the chassis leaving no room whatsoever for airflow.

More choice on the market is good but given that it's basically a 92mm Wraith Prism cooler with about 1/4 the fin stack, I can't see it being very capable unless that fan is running at it's maximum 3600RPM. AMD's Wraith Prism cooler is pretty decent by "free" cooler standards but it's still too weak to quietly cool the 105W TPD processors it used to be bundled with, and that's the same basic spec: Quad-heatpipe, 92mm heatsink and fan. However, it's over three times the height of this H4A cooler and the fin stack is 62mm instead of 15mm (my best guess, given the pictures shown here).

Zen 4 with X suffix are 105W by spec, so obviously not meant for them.

It probably can, but at unreasonable noise levels. 3600RPM is quite high.
 
That royal purple fan................nice.............
 
what a lovely looking cooler! i'm eager to try it with a fan duct on original velka 3 v1.1 to avoid the turbulence i have with nh-l9i+am5 adapter.
another GREAT feature i see in this akasa (and i'd love to see in other coolers as well) is that i can install the cooler from the front of the pc without needing access to the back of the motherboard, like in amd's super useful wraith stealth. A life saver for sandwich style cases like dan a4-sfx, velka 3, k39 and many other newer brands and models where you'd otherwise have to at least remove the gpu to access the bolts located in the back of the mobo. Having a cupboard full of low profile coolers I still use wraith stealth sometimes because of that ease of use and removal / replacement of CPU.
