The history of coolleo is intrinsically linked to the development of its parent company’s thermal engineering operations. According to published company records, the underlying business was founded in 2005, initially producing professional heatsink products for servers. In 2007, it introduced the Coolserver brand for server thermal solutions. By 2009, the company had evolved into an integrated thermal solution provider covering research and development, manufacturing, and sales, including OEM heatsink production for international brands.[1]

The company obtained ISO 9001 quality management certification in 2015 and subsequently expanded its thermal technology applications to include automotive, photovoltaic systems, LED products, personal computers, servers, data centres, and graphics cards.[1]

Development of coolleo

The consumer-oriented coolleo brand was launched in 2021. The company describes coolleo as its dedicated consumer PC brand, initially focusing on products such as PC chassis, power-related components, and cooling hardware for individual enthusiasts.[1] This distinction highlights that coolleo is not merely a newly created PC cooling company; rather, its brand identity is built upon a manufacturing business with experience in heatsinks and thermal solutions dating back to 2005.[1]

The official coolleo product catalogue encompasses several key categories:

• Air coolers: Tower-style CPU heatsinks ranging from compact models to large dual-tower designs.
• Liquid coolers: Primarily all-in-one (AIO) CPU liquid cooling systems.
• Fans: PC cooling fans and related fan products.
• Chassis: Computer cases and related PC hardware.
• Thermal grease: Thermal interface materials.
• Accessories: Items such as CPU bending correction components, RGB controllers, and fan hubs.[1]

While the product range extends beyond a single category, CPU cooling remains the central pillar of the brand’s identity.

CPU air coolers

Air cooling is the segment where coolleo has established its strongest reputation. The catalogue includes compact single-tower coolers alongside large dual-tower models. For example, the A60 PRO is a dual-tower design utilising six heat pipes, while the FF135 series features six anti-gravity heat pipes and a full reflow soldering process.[1]

coolleo has incorporated features increasingly common among enthusiast PC coolers, including:

• Multiple heat pipes
• Direct-contact or soldered thermal interfaces
• Fluid dynamic bearing (FDB) fans
• High static pressure fans
• ARGB lighting
• Tool-free fan mounting
• Digital displays
• Anti-gravity heat pipe designs
• Large dual-tower heatsinks

The B40S DIG BK V2, for instance, combines four direct-contact heat pipes with a digital display, tool-free fan installation, and an RGB fan.[1]

Flagship P60T series

One of coolleo’s most prominent performance-oriented product families is the P60T series. The company states that its flagship P60T air cooler achieved first-place performance results in an annual benchmark review in 2023. Development of the series continued with the launch of the P60T V3 Ultra in January 2026.[1]

The P60T V3 Ultra employs a dual-fan configuration with 120 mm and 130 mm fans, fourth-generation anti-gravity heat pipes, fully soldered fins, and a reinforced metal structure.[1] This illustrates coolleo’s strategy of competing not only in the budget cooler market but also in the high-performance enthusiast segment.

Liquid cooling

coolleo officially entered the liquid cooling market in 2024, expanding its portfolio beyond conventional heatsink and fan designs.[1] The current range includes several AIO liquid coolers, featuring models with integrated displays and various radiator configurations.

In February 2026, the company announced a concealed tubing design for its AIO products. This concept allows tubing to be routed through less visible areas of a PC chassis, aiming to create cleaner builds without adding a premium specifically for the concealed tubing feature.[1]

coolleo’s marketing and product development place considerable emphasis on thermal engineering. The company’s stated philosophy revolves around protecting CPU performance by controlling heat, guided by three major principles:[1]

1. Extreme performance: Improving cooling efficiency, airflow, and thermal stability.
2. Reliable quality: Emphasising material selection, manufacturing precision, and testing.
3. Smart value: Balancing performance and quality against cost.

Notable engineering features include anti-gravity heat pipes, reflow and full soldering, optimised fin structures, FDB fans, and direct-contact thermal designs. These technologies aim to increase heat transfer efficiency while maintaining acceptable noise levels and compatibility.[2]

The company behind the coolleo and Coolserver thermal businesses reports a substantial manufacturing operation in mainland China. Published company information states that the facility covers more than 21,000 square metres and contains CNC machinery, punching equipment, automated welding lines, fan production lines, liquid cooling production lines, and automated assembly lines. It reports a production capacity of approximately 500,000 units per month, with sales into China as well as international markets in Asia, Europe, and the United States.[3]

These figures are company-provided claims rather than independently audited statistics.

Understanding coolleo requires recognising its relationship with Coolserver. Both brands originate from the same thermal manufacturing background but address different markets:[3]

• Coolserver focuses primarily on professional and industrial thermal solutions, including server heatsinks, server cooling, GPU cooling, and customised thermal products.
• coolleo focuses on consumer PC hardware, particularly enthusiast and gaming-oriented cooling products.[1]

In simplified terms, Coolserver serves the professional server thermal solutions market, while coolleo serves the consumer PC and enthusiast hardware market. This makes coolleo part of a broader thermal engineering business rather than an isolated consumer electronics brand.

coolleo’s stated brand philosophy centres on the premise that thermal performance determines the sustained performance capability of a computer. Current messaging describes heat as a limitation on computing performance and positions coolleo cooling products as a means of removing that limitation. The company states its long-term goal is to become synonymous with “performance protection” among gamers and creators.[1]

The company also emphasises making higher-end cooling technology accessible through what it terms “smart value”, aiming to combine strong performance with competitive pricing.[1]

coolleo has expanded rapidly in the enthusiast CPU cooling market. Key milestones include:

• 2023: The P60T achieved first-place performance in an annual benchmark review.
• 2024: coolleo entered the AIO liquid cooling market.
• 2025: Launch of new high-end dual-tower products such as the Caesar S1 and S2.
• January 2026: Introduction of S60/S61 single-tower flagship coolers and the P60T V3 Ultra.
• February 2026: Announcement of concealed tubing technology for AIO liquid coolers.[1]

These developments indicate an attempt to transition from being primarily known for value-oriented CPU air coolers to becoming a broader enthusiast PC cooling brand.

coolleo occupies a distinct position in the PC hardware market. It is not one of the traditional globally dominant PC component brands such as Noctua, be quiet!, Corsair, Cooler Master, or NZXT. Instead, coolleo is a relatively newer consumer-facing brand backed by a company with a longer history in thermal manufacturing.

Its competitive proposition combines professional thermal manufacturing experience, enthusiast-oriented engineering, and aggressive price-to-performance ratios. This is particularly evident in its air coolers, where the company frequently emphasises high heat pipe counts, soldered construction, large heatsinks, and high-performance fans while attempting to remain competitively priced.

The brand is officially styled coolleo, generally written in uppercase in English-language branding. In China, it is also known as 酷里奥 (Coolleo). The company’s Chinese consumer-facing material identifies the brand as “coolleo酷里奥”.[1]

Multiple coolleo trademark filings involving different companies exist, which can make trademark records confusing. However, coolleo’s current official website identifies Shenzhen Juhong Electronics Co., Ltd. as the company behind the brand.[1]
