Alpenföhn is a company which manufacturers cooling components for IT systems, which started its activity in 2008. The Alpenföhn line includes CPU coolers, fans and accesorries which include: thermal compound, storage cooling systems and fan mounting systems. Das im Lieferumfang enthaltene Schraubmontagesystem wurde so konstruiert, dass eine bestmögliche Kompatibilität auf mini-ITX Mainboards gewährleistet wird. Alpenföhn have further innovated by attaching a 92-millimeter fan to the base of a high quality heatsink and in so doing have cut the overall height of the cooler to just 47 millimetres. This extraordinary design also has the added benefit of reducing fan noise. A Premium Heatsink made from high quality Materials Durch den intelligenten Einsatz der Materialien und einem komplexen Lamellendesign wird der perfekte Spagat zwischen Leistung und Kompatibilität geschaffen. Zudem eignet sich der Kühler mit seinen maximal 47mm Höhe ideal für den Einsatz in Gehäusen von DAN Cases. Best Low-Profile CPU Cooler Overall: Noctua NH-L9i / L9i17xx / L9a-AM4 has excellent compatibility and performs solidly for the size.

The downside, of course, is fan noise: Corsair’s H60 hit 52 dBA, whereas most low-profile air coolers tended to stay around or below 40 dBA. So that’s a compromise you’ll have to make if you want the better temperatures an AIO can provide. While that won’t be an issue for most builds, the C7 RGB is perfect for compact small form factor cases with less than two inches of CPU cooler clearance. If you’re building in one of those, the Wraith Stealth’s 2.12-inch height puts it out of contention; that’s where the C7 RGB comes in. The sides of the box have a monochrome diagram of the cooler, which presents the overall dimensions of the heatsink. The basic technical specifications of both the heatsink and the included fan can also be found here. Noctua’s NSPR is an in-house rating that indicates cooling performance in relation to other Noctua products. Higher numbers are better.Noctua’s NH-L9 family of low-profile CPU coolers offer great cooling (for their size) and an excellent affordable price, making them an easy choice for anyone needing a bonafide small form factor CPU cooler. If you consider that the Wraith Stealth also has RGB and comes free with an AMD CPU, the C7 RGB might seem like a bad deal. But there are two situations where we think the C7 RGB makes sense. For both solutions I‘m planning to install two noctua case fans as exhaust at the bottom of the case.

The built-in 92x92x15mm PWM fan has a 4-pin PWM connector and can be controlled via the motherboard. This allows a speed adjustment between 800 and 2800 rpm, allowing a minimum of 14 dB(A) and a maximum of 80.03 m³/h. The build quality is great, the dark coating is evenly applied on all components, and the cooling fins have smooth edges. The baseplate surface is smooth and will have optimal spread for the thermal compound. The NH-L12S takes the general design of low-profile CPU coolers like the NH-L9 but adds some much-needed room between the heatsink fans and the cold plate. This provides more room for airflow and helps bring temperatures down. It still can’t compete with a proper tower cooler, but the performance is noticeably better than sub-two-inch coolers. Heatpipes befördern die Abwärme des Prozessors schnell und effizient an die verlöteten Aluminium Lamellen des Kühlkörpers. What is your opionion and experience about the two CPU cooler solutions? Which one has less noise? Which one has better TDP (also regarding to higher TDP with Zen 3 CPU‘s)?

Coming in at 1.45 inches tall, the NH-L9 CPU coolers will fit almost anywhere, even in some of the smallest Mini-ITX cases available. This effortless compatibility makes them an easy default choice for the majority of SFF builders. Of course, the great performance for the size helps too. One part of the industry that requires millimeter precision is building systems for small form factor designs – being able to take advantage of every small bit of volume inside a chassis but also maximize performance yet minimize noise is a critical element to the success of these systems. ID-Cooling has thrown another hat into the ring when it comes to cooling the processor, something that can be a tough job in such an enclosed space. The new IS-47K is designed with a maximum height of 47mm, and is apparently rated for CPUs up to 130 W.
