Overview

The Ocypus Gamma A40 BK is a compact single-tower air CPU cooler designed for space-conscious PC builds. Standing just 133mm tall, it pairs a 100mm PWM fan with a fully black-coated tower body, making it a versatile choice for a wide range of system configurations.
Cooling is handled by four 6mm copper heat pipes using a direct-touch design that maximizes contact area with the CPU. This allows the cooler to support processors with a TDP of up to 200W, which covers most mainstream CPUs on the market today. The top cover features a classic round dot-matrix element, adding a subtle design touch to the otherwise minimalist aesthetic.
Positioned as an entry-to-mid-tier cooler, the Gamma A40 BK is aimed at users building compact gaming or productivity PCs. It supports Intel LGA 115X/1200/1700/1851 and AMD AM4/AM5 sockets, offering broad compatibility across both major platforms.

Compatibility Guide

The Gamma A40 BK supports Intel LGA 115X/1200/1700/1851 and AMD AM4/AM5 sockets. This covers a wide range of current and recent processors from both Intel and AMD, including mainstream Core and Ryzen series chips.
With a height of just 133mm, this cooler fits comfortably in most mini-tower and slim cases where taller coolers would not. However, it is always wise to check the CPU cooler clearance specification of your case before purchasing, as some ultra-compact cases may still present clearance issues.
Memory clearance is generally good thanks to the single-tower design, but users with tall memory heat spreaders should verify that the fan does not interfere with the first DIMM slot. Adjusting the fan position or choosing low-profile memory can help avoid conflicts.

Product Info

The Ocypus Gamma A40 BK is a compact air cooler that sits in the entry-to-mid-tier segment of the market. Its 133mm height and 100mm PWM fan make it a practical choice for builds where space is at a premium, while the four 6mm direct-touch heat pipes provide efficient heat transfer for CPUs up to 200W TDP.
The cooler measures approximately 100mm in length, 25mm in width, and 133mm in height, with a weight of around 390g. This lightweight construction reduces stress on the motherboard and simplifies installation, making it accessible even for first-time builders.
In terms of market positioning, the Gamma A40 BK competes with other compact single-tower coolers in the budget-to-mid-range price bracket. It offers a good balance of cooling performance, noise levels, and compatibility for mainstream systems, though it is not designed to handle extreme overclocking scenarios.

Best Use Cases

  • Compact gaming PC builders who need a cooler that fits in tight spaces. The 133mm height allows installation in many mini-tower cases where larger coolers simply won't fit. Users with full-tower cases and no space constraints may find larger coolers offer better performance.
  • Users prioritizing quiet operation. The 100mm PWM fan adjusts its speed based on load, keeping noise levels low during idle and light tasks while ramping up only when needed. Those who run constant heavy workloads might prefer a larger fan for higher airflow.
  • Budget-conscious builders seeking good value. The Gamma A40 BK delivers solid cooling for mainstream CPUs at an accessible price point. Enthusiasts planning aggressive overclocking or running high-end processors should look at more substantial cooling solutions.

Things to Consider

The 200W TDP rating is a guideline rather than an absolute limit. Actual heat output depends on clock speeds and voltage settings, so users running sustained heavy workloads should consider whether this cooler provides sufficient headroom for their specific CPU.
A 100mm fan moves less air than a typical 120mm fan, so case airflow becomes more important. In poorly ventilated cases, the cooler's performance may suffer. Pairing it with good case fans that exhaust hot air efficiently is recommended.
As a single-tower design, the Gamma A40 BK offers more modest cooling capacity than dual-tower coolers. For high-end CPUs like Ryzen 9 or Core i9 models used under constant load, a larger cooler would be a safer choice to maintain lower temperatures.

FAQ

Q: Does this cooler support the Intel LGA 1851 socket?
A: Yes, the Gamma A40 BK supports Intel LGA 115X/1200/1700/1851 sockets, so it is compatible with the latest Intel platforms.
Q: Will this cooler interfere with memory modules?
A: The single-tower design generally provides good memory clearance. However, if you use memory with tall heat spreaders, you may need to adjust the fan position or verify clearance before installation.
Q: What level of cooling performance can I expect?
A: This cooler supports CPUs with a TDP of up to 200W. It handles mainstream and mid-range processors well, but for high-end CPUs under heavy load, a larger cooler would be more appropriate.
