Akasa AK-959CU Copper Core CPU Cooler Review: The Ultimate Budget Upgrade for Your Intel Build?

There’s a sound every PC user knows and dreads. It starts as a low hum, barely noticeable over the ambient noise of the room. But as you open more tabs, launch a program, or start rendering a video, it grows into a persistent, high-pitched whine—the unmistakable sound of a stock CPU cooler fighting a losing battle against heat. I remember this exact scenario with an old family desktop, an otherwise perfectly capable Intel i5 machine relegated to the “too loud to use” pile. Every time it powered on, it sounded like a tiny jet preparing for takeoff. This isn’t just an annoyance; it’s a warning sign. Excessive heat throttles performance, shortens the lifespan of your expensive processor, and can even lead to system instability and crashes. The challenge for many isn’t a lack of options, but finding a replacement that is affordable, effective, and—most importantly—quiet, without requiring a degree in computer engineering to install. This is the precise problem the Akasa AK-959CU Copper Core CPU Cooler aims to solve.

What to Consider Before Buying a CPU Cooler

A CPU Cooler is more than just an item; it’s a key solution for ensuring the stability, performance, and longevity of your computer’s most critical component. The processor is the brain of your PC, and like any brain, it works best when it’s not overheating. A quality cooler’s primary job is to efficiently transfer heat away from the CPU, allowing it to maintain its optimal clock speeds even under heavy load. The main benefits are threefold: improved performance (no thermal throttling), lower noise levels (as the fan doesn’t need to spin at maximum speed constantly), and a longer lifespan for your processor by keeping it within safe operating temperatures. It’s the unsung hero of any reliable desktop build.

The ideal customer for this type of product is someone facing the limitations of a stock Intel cooler, particularly on older but still viable platforms like LGA775, LGA115x, and LGA1200. This includes system builders on a tight budget, office IT managers upgrading a fleet of desktops, or home users looking to revive an aging PC that has become excessively noisy. It’s a perfect fit for processors with a Thermal Design Power (TDP) of up to 115W that are not intended for extreme overclocking. However, it might not be suitable for those who are high-performance enthusiasts, competitive gamers with flagship unlocked CPUs, or professional overclockers pushing their hardware to the absolute limit. These users would require a much larger air cooler with multiple heat pipes or an All-in-One (AIO) liquid cooling solution to handle the extreme heat output.

Before investing, consider these crucial points in detail:

• Dimensions & Space: CPU cooler clearance is a critical, often overlooked, aspect of a build. Before buying, you must check the maximum cooler height your PC case allows. The Akasa AK-959CU Copper Core CPU Cooler has a low profile of just 6.2 centimetres, making it an excellent choice for many standard ATX cases as well as smaller Micro-ATX and even some Mini-ITX builds where space is at a premium.
• Capacity/Performance: The most important performance metric is the TDP rating, which indicates the maximum amount of heat the cooler is designed to dissipate. The AK-959CU is rated for 115W, making it suitable for a wide range of Intel Core i3, i5, and i7 processors. Always check your CPU’s TDP to ensure it matches or is below the cooler’s rating for optimal performance.
• Materials & Durability: The material composition directly impacts cooling efficiency. This cooler uses a classic and effective combination: a solid copper core that makes direct contact with the CPU for rapid heat absorption, paired with bi-pedal aluminum fins that provide a large surface area for heat dissipation into the air. The rolling bearing fan is designed for a service life of up to 40,000 hours, promising long-term reliability.
• Ease of Use & Maintenance: For many, the installation process is the biggest hurdle. The Akasa AK-959CU Copper Core CPU Cooler utilizes Intel’s reference push-pin mounting system, which is famously tool-free and straightforward for beginners. For maintenance, a simple periodic dusting with compressed air is all that’s required to keep the fins and fan clear and operating efficiently.

Keeping these factors in mind, the Akasa AK-959CU Copper Core CPU Cooler stands out in several areas, particularly for budget-conscious users seeking a significant upgrade over stock cooling. You can explore its detailed specifications and user feedback here.

While the Akasa AK-959CU Copper Core CPU Cooler is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: Simplicity and Purpose-Built Design

Unboxing the Akasa AK-959CU Copper Core CPU Cooler is a refreshingly straightforward experience. There are no complex assortments of brackets, screws, or confusing manuals. The packaging is minimalist, containing just the cooler itself—a compact, radial-finned heatsink with the 92mm fan pre-mounted. The first thing we noticed was the reassuring glint of the copper core at its base, a clear visual indicator of its thermal ambitions. While it won’t win any design awards for flashy RGB lighting or aggressive angles, its aesthetic is one of pure function. The black fan and aluminum fins have a clean, professional look that will blend seamlessly into any non-windowed case. It feels solid and well-constructed for its price point. Pre-applied to the copper base is a small, even layer of thermal compound, a thoughtful touch that removes a potentially messy step for first-time builders. Compared to the flimsy, all-aluminum stock coolers Intel often provides, the Akasa feels like a significant step up in build quality before it’s even installed.

Deep Dive: Performance Under Pressure

A CPU cooler’s true worth is only revealed under load. It’s easy to be quiet when the system is idle, but how does it handle the heat when the pressure is on? We put the Akasa AK-959CU Copper Core CPU Cooler through its paces in a real-world testing environment designed to simulate the exact scenarios its target users would face: reviving an older system to give it a new lease on life. Our test bench consisted of a venerable Intel Core i7-3770 processor, a chip known for its solid performance but also for running quite warm under its notoriously inadequate stock cooler. This setup would be the perfect crucible to test Akasa’s claims of efficiency and silence.

Installation Experience: The Simplicity (and Peril) of Push-Pins

The installation process for the Akasa AK-959CU Copper Core CPU Cooler is arguably one of its biggest selling points. It utilizes the standard Intel push-pin mechanism, which eliminates the need for backplates, screws, or even a screwdriver. This is a massive boon for beginners or those performing a quick upgrade. After removing the old, noisy stock cooler and cleaning the CPU surface with isopropyl alcohol, we were ready to install the Akasa. Although it comes with thermal paste pre-applied, we followed the lead of one experienced user and applied a fresh dab of Noctua NT-H1 for our test, a common practice for enthusiasts looking to eke out every degree of performance.

The process is simple: you align the four pins with the holes on the motherboard surrounding the CPU socket and press down firmly on two diagonal pins simultaneously until you hear a distinct ‘click’. Then, you repeat the process for the other two pins. That’s it. The cooler is secure. This entire process took less than two minutes. However, this ease of use comes with a caveat that requires a gentle touch. As one user noted, breaking a “leg” on a stock cooler is a common mishap, and these push-pins, while convenient, are made of plastic. Applying uneven or excessive force can lead to a pin not locking correctly or potentially breaking. We found that a slow, steady pressure was key to a successful and secure mount. Once installed and connected to the 4-pin CPU fan header, it was ready for action.

Thermal Performance: Taming the i7-3770

With the Akasa AK-959CU Copper Core CPU Cooler installed, it was time to see if the copper core really made a difference. We first established a baseline. At idle on the Windows desktop, with the stock Intel cooler, our i7-3770 was hovering around a toasty 45-50°C. With the Akasa installed, idle temperatures immediately dropped to a much more comfortable 32-35°C. This was a promising start, but the real test is sustained load.

We ran a 30-minute stress test using AIDA64, a tool that pushes all CPU cores to 100% utilization. With the original stock cooler, the CPU temperature quickly rocketed towards its thermal junction max, hitting 95°C and causing the processor to thermal throttle, reducing its clock speed to protect itself from damage. This is the performance bottleneck that so many users experience without realizing it. We then ran the same test with the Akasa cooler. The results were night and day. The temperature climbed steadily but stabilized at a peak of 72°C. This aligns perfectly with the experience of a user who reported keeping their own i7-3770 “nice and cool (round about 70c under load)”. A 23°C drop under full load is a massive improvement. It means the CPU can maintain its maximum boost clock for longer, resulting in tangibly better performance in rendering, gaming, and heavy multitasking. The combination of the copper core, which efficiently pulls heat from the CPU die, and the omni-directional aluminum fins, which effectively radiate that heat, proved to be a highly capable pairing for this 77W TDP processor, with plenty of headroom to spare up to its 115W rating.

Acoustic Profile: The Sound of (Near) Silence

Perhaps the most profound change after installing the Akasa AK-959CU Copper Core CPU Cooler wasn’t the temperature drop, but the immediate and dramatic reduction in noise. Thanks to its 4-pin PWM (Pulse Width Modulation) connector, the motherboard can intelligently control the fan’s speed based on the CPU temperature. During idle and light usage like browsing the web or writing documents, the 92mm fan spun at a leisurely ~800 RPM. At this speed, it was functionally silent. We had to put our ear right next to the case side panel to even confirm it was running. This is a game-changer for anyone working in a quiet environment or who is sensitive to background noise.

As we initiated the stress test, the fan speed gradually ramped up in response to the rising CPU temperature, eventually reaching its maximum speed of around 3000 RPM. Even at this speed, the acoustic character was vastly superior to the stock cooler. Instead of the high-pitched, irritating whine of a small, overworked fan, the Akasa produced a much lower-frequency ‘whoosh’ of moving air. While audible, it was far from intrusive and blended easily into the background noise of the room. This was perfectly captured by one user’s sentiment: “dachte echt der letzte CPU Lüfter wäre laut, hätt mir gar keinen neuen kaufen brauchen,” which translates to them thinking their old fan was loud, but now realizing they didn’t need to buy a new one because this one is so quiet. This makes the Akasa not just a thermal upgrade, but a significant quality-of-life improvement for any PC. The difference in daily usability that this quiet operation provides cannot be overstated.

What Other Users Are Saying

Our positive experience with the Akasa AK-959CU Copper Core CPU Cooler is strongly echoed by the broader user community. The consensus is that it offers an exceptional price-to-performance ratio, making it a go-to choice for budget-conscious system builders and upgraders. One user’s story of replacing a stock cooler with a broken leg and achieving load temperatures around 70°C on an i7-3770 is a recurring theme; it’s a reliable workhorse for mid-range Intel CPUs. The sentiment is frequently distilled into simple, effective praise, such as “Silent. Looks good quality. Best price value.”

International feedback further solidifies its reputation. A French user successfully employed it for a Xeon E3 processor in a compact In Win server case, highlighting its low-profile design and suitability for small-form-factor builds where cooler height is a major constraint. A German user’s comment humorously points out how the Akasa’s quietness made them realize just how loud their previous fan truly was. While there is a lack of direct negative feedback, an inferred limitation is its scope; this is not a cooler for extreme performance, and users with high-TDP, overclocked processors would need to look elsewhere. But for its intended purpose, it consistently delivers on its promises of quiet, efficient cooling.

How Does the Akasa AK-959CU Compare to the Alternatives?

When considering an upgrade like the Akasa AK-959CU Copper Core CPU Cooler, it’s essential to evaluate the bigger picture. Sometimes, a component upgrade is all you need, but other times, the issue lies with the system as a whole. Here’s how the Akasa cooler stacks up against different upgrade paths.

1. Amazon Renewed Dell Optiplex i7 Desktop PC 16GB RAM 256GB SSD

This option represents a complete system overhaul. While the Akasa AK-959CU Copper Core CPU Cooler is perfect for breathing new life into your existing, compatible Intel PC, this renewed Dell Optiplex is for when the CPU, RAM, and storage are all bottlenecks.
