Thermaltake TH240 ARGB Sync V2 CPU Liquid Cooler - Infinity Mirror

In this review of the Thermaltake TH240 ARGB Sync V2 the bottom line is simple: it is a compact, visually striking 240mm AIO aimed at builders who want motherboard-synced lighting and reliable midrange cooling in small to medium cases. The cooler's infinity mirror cap and dual CT120 ARGB fans are the headline features, while a copper chamber and high-flow pump keep temps in check. It is best for enthusiasts who value RGB control through ASUS, GIGABYTE, MSI or ASRock software and need a slim 27mm radiator for tighter builds.

Key Features

• ARGB Sync: Designed to synchronize with ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light Sync and ASRock Polychrome for unified motherboard-controlled lighting.
• Infinity Mirror Cap: The new industrial 360-degree rotational cap with infinity mirror lighting adds depth and dynamic visuals to a system build.
• Copper Cooling Chamber: A thickened 20mm copper chamber combined with a copper base plate accelerates heat transfer for consistent CPU cooling under load.
• Slim 27mm Radiator: The 27mm slim radiator fits more compact cases while still providing adequate surface area for a 240mm AIO loop.
• Included Fans: Two CT120 ARGB 120mm fans provide PWM control between 500 and 2000 RPM to balance airflow and noise.
• Compatibility: Broad socket support includes Intel LGA 2066/2011-3/2011/1700/1200/115x and AMD AM5/AM4/AM3+/AM3/AM2+/AM2/FM2/FM1 for versatile platform use.

Who It's For

The TH240 V2 ARGB is aimed at PC builders who want striking ARGB lighting that is controlled from the motherboard and who are building in small to medium cases that accept 240mm radiators. Its slim 27mm radiator and compact layout make it a good match for chassis with limited radiator depth while still offering two 120mm ARGB fans.

Users who need extreme overclocking headroom or quieter operation at very high sustained loads might consider larger 360mm radiators or higher-end pumps, since this 240mm AIO is tuned for balanced performance and visual impact rather than pushing absolute thermal limits.

Pros & Cons

Pros

• Strong visual impact from the infinity mirror cap and fully motherboard-synced ARGB lighting.
• Copper base plate and thickened copper chamber help maintain stable temperatures under demanding loads.
• Slim radiator design fits in tighter cases while still providing effective cooling for most builds.
• Includes two CT120 ARGB fans with PWM control for adjustable airflow and performance.

Cons

• Noise reports are mixed among users, with some finding the pump and fans quieter than expected and others noting noticeable noise under load.
• As a 240mm AIO it may not match the absolute thermal headroom of larger 360mm solutions for extreme overclocks.

Frequently Asked Questions

Does this AIO work with my motherboard RGB software?
Yes, it is designed to sync with ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light Sync and ASRock Polychrome using a 5V ARGB header.

Will the slim radiator fit in small cases?
The 27mm slim radiator is intended for small to medium cases that support 240mm AIOs, making it a good option where depth is limited.

Is cooling performance adequate for gaming?
Customers report temperatures below 50C under demanding loads in many setups, so it is suitable for typical gaming and productivity use, though extreme overclocks may benefit from larger radiators.
