The New Alpine CPU Coolers from ARCTIC


ARCTIC Alpine CPU Cooler Series

With the new Alpine 12 and Alpine AM4 series, we are updating our portfolio of cost-effective CPU coolers.

The Alpine 12 series is designed for the 115x sockets from Intel, while the Alpine AM4 series is exclusively compatible with the namesake AM4 socket from AMD. Alpine AM4 series, except the Passive, are also backward compatible with AM3+, AM3, AM2+, AM2, FM2 and FM1.

The Alpine 12 Passive and Alpine AM4 Passive, available since summer 2018, are now being supplemented with the launch of the Alpine 12 and Alpine 12 CO. Further versions for AMD and Intel will follow shortly. The older versions Alpine 11, Alpine 20, Alpine 64 and Alpine M1 are end-of-life products that will no longer be produced.

Newly developed heatsinks

All new Alpine CPU coolers feature newly developed heatsinks.

The passive versions achieve an optimized heat dissipation to the environment through the black anodization of the heatsink. This noticeably increases the cooling performance in a fanless system.

The actively cooled Alpine 12 and AM4 models in turn have a new radial heatsink. The high thermal conductivity of the aluminum is fully retained in a new type of extrusion.

The novel production process makes it possible to produce a powerful and at the same time very compact heatsink. The particularly fine cooling fins of the new Alpine coolers are fanned out in a Y-shape. This increases the surface area of the heatsink and also improves the cooling performance.

Affordable CPU cooler for AMD and Intel

All actively cooled Alpine 12 and Alpine AM4 models use our advanced, PWM-controlled fan technology. As a result, all Alpine coolers run very efficiently, with low power consumption and at the same time within a very wide RPM range. In addition, the new Alpine series supports a 0 dB mode – if the a PWM signal drops below 5%, the fans turn off, ensuring absolutely silent cooling of the CPU.

All new Alpine 12 and Alpine AM4 CPU coolers are delivered with pre-applied MX-2 thermal compound. This guarantees a quick and easy installation.

Anodization of CPU Coolers

Black, slim and surprisingly powerful for a passive CPU cooler: The undoubtedly most striking feature of the new ARCTIC Alpine Passive coolers is the black heat sink. Unlike the thermal coating of the Freezer 33 eSports family, however, this is not a thermal coating, but the color is created by anodization.

But what is this and how does it work?

Anodic oxidation is a special process in which the object to be treated is placed in a conductive liquid and this liquid is connected to a voltage source. The object to be treated is one of the poles, the opposite pole is usually another, non-rusting metal such as lead, aluminum or stainless steel.

To color the Alpine Passive, the conductive liquid is accompanied by black dye, which accumulates in the oxidation process in the pores of the aluminum.

The advantage: It forms an extremely dense, micro-porous and dust-free barrier layer, which additionally functions as an electric insulator.

Up to 3 °C better cooling performance

For the end-user, this complex process brings one major advantage:

The black anodization ensures improved heat dissipation in fanless operation.

Due to the changed surface structure, micro turbulences occur during heat radiation which lead to a higher cooling capacity.

Compared to other passive coolers of the same size, but without anodization, the ARCTIC Alpine Passive is doing very well: Internal tests showed an improved cooling performance of up to 3 °C. It should be noted here that this improved cooling performance is limited to the passive mode. If a fan provides an active airflow, the improved passive heat dissipation wont have the same effect.

For quiet PC systems

The passive cooler works absolutely silently and cools processors up to 35 W TDP – with optimal air circulation in the case even up to 47 W TDP – effectively.

The ARCTIC Alpine 12 and AM4 Passive are therefore particularly suitable for computers that should be as quiet as possible, such as HTPCs.

Liquid Cooling Solutions – Step Up Your Cooling System

Every computer, from home theater PC to the most hulking of gaming system, generates heat during operation- and this heat can kill your PC’s precious internals if you’re not careful.  For quite some time, air cooling systems were the solution to stop the CPU and GPU from overheating. As this method is quite successful, air coolers are still extremely popular in the marketplace. But there are some new solutions, as well.

The Next Level of Cooling

Over the time, cooling solutions were reworked to new sizes and methods. Thereby, liquid coolers became the next level of cooling. Especially for the CPU, this method becomes more and more popular. Here, the liquid used is a low conductive mixture that loops from the radiator to the CPU block which dissipates heat faster than air cooling does. That way, the CPU will run cooler at idle and under load.

No Worries

New liquid coolers are quiet, save internal space where it matters most, and perform well – all at a price that’s not far off from a good air cooler. Who thinks that water and a computer system won’t go together can be reassured.  When you follow the installation instructions correctly, there should be no leaks and therefore, your system stays dry. Moreover, thanks to the innovation of all-in-one water coolers like the ARCTIC Liquid Freezer, there is only need to install it once and the cooler won’t require to be maintained constantly in the future.

Easy Installation

The easiest way to get into liquid cooling is with an all-in-one loop. These consist of a single closed loop with a radiator on one end and a pump/water block combo on the other. The system is pre-filled and pre-sealed so you don’t need to mess with it. You just install the radiator and its included fan onto one of your case’s existing fan mounts, attach the water block to the CPU and fire it up.
Most all-in-one loops cool the CPU only. There are some all-in-one loops for GPUs, like our ARCTIC Accelero.

The innovative PWM Sharing Technology – Use PST to control the fan speed

How is the temperature decreased by PST?

Fans using the PWM feature just function with the necessary speed to endure maximum cooling at the lowest noise level.
Thanks to the patented innovative PWM Sharing Technology (PST), up to 5 fans (including CPU fans) connected to the ARCTIC F PWM fan can share the PWM signal. The speed of all the fans in this PST system is then centrally controlled by a single PWM signal via BIOS.
This means if the system load becomes greater, the fan speed of all fans within the PST system increases to reduce the chassis temperature. If the utilization is low, these fans will operate at a relatively low speed to ensure a proper cooling.

Thermal Pads or Thermal Paste – Differences and Advantages

The surface of a CPU or a heat sink is never entirely flat. If you place a heatsink directly on a CPU, there will be tiny, nearly invisible, gaps between the two. Since air conducts heat poorly, these gaps have a very negative effect on the heat transfer. Therefore, an interface material with a high thermal conductivity is needed to fill these gaps to improve heat conductivity between CPU and heatsink.
Here, you can decide between using thermal paste and thermal pads. But when should you use which solution? What are their differences and what advantages do both solutions have?

Thermal Paste

Thermal grease, thermal compound, thermal goop, thermal gunk or heat paste – thermal paste has lots of different names. It is a sticky paste applied directly on the heatsink or CPU and the most commonly used interface material in the electronics cooling area. Thermal compound with a good quality will provide the best possible performance. Unfortunately,  to apply thermal paste can be quite messy. Also, thermal paste isn’t the best way to fill bigger gaps sometimes. Here, you can use thermal pads.

A tutorial how to properly apply thermal compound, can be found here:

Thermal Pads

Thermal pads are a lot easier to install than thermal grease. Unfortunately, they aren’t as effective as a thin layer of thermal paste. Some stock CPU coolers come with pads, because they’re nice and clean, and they’ll work fine.
But they are one-shot solutions only. You have to replace the pad if you ever remove the heatsink from its mounted position, because the heat of the operating CPU will have caused the thermal pad to conform the top. So, once you move the heatsink there will be new gaps between the surfaces. So never forget: If you dismount the heatsink, replace the thermal pad and remove all debris.

Avoid Common Mistakes

When using thermal pads or thermal paste, there are some mistakes that are often made. So, here are some ideas to avoid those:
Never use thermal compounds and thermal pads together. Just because you use both, the effect won’t increase. The reverse is true.  Adding thermal grease on top of a thermal pad actually reduces the ability of heat to flow to the heatsink.
Also, never stack several pads on top of each other. Two or three pads on top of each other between the CPU and a heatsink might kill the CPU.
