Cooler Master Seidon 120XL AIO CPU Liquid Cooler
The Seidon 120XL is a performance-oriented 120mm AIO cooler featuring an extra-thick 38mm radiator designed to handle high-wattage overclocked CPUs. Dual 120mm PWM fans deliver a wide RPM range for precise noise-to-performance tuning, complemented by an UltraFine Microchannel water block and zero-maintenance sealed loop.Overview
The Cooler Master Seidon 120XL pushes beyond standard 120mm AIO performance with a 38mm thick radiator purpose-built for high-wattage overclocked processor loads. The extra fin depth gives the dual 120mm PWM fans substantially more air-contact surface to work with, enabling this compact footprint cooler to punch above its class in thermal dissipation. An UltraFine Microchannel cold plate inside the copper water block maximises the contact surface between coolant and CPU heat spreader, and the closed-loop design is factory sealed for zero-maintenance longevity.

FAQ
Why is the radiator 38mm thick instead of the standard 25mm?
The extra thickness provides more fin surface area for heat exchange, which is essential when cooling CPUs running at overclocked frequencies that exceed standard TDP ratings.
Does dual fan mean louder operation?
Not necessarily. The PWM control allows both fans to run at low RPM for quiet operation during light loads, ramping up only when thermal demands require it.

Frequently Asked Questions
Who needs a 38mm thick radiator for their office or server setup?
Users running high-performance CPUs, overclocked systems, or server workstations in warm environments benefit from the extra-thick radiator's superior heat dissipation.
How does the dual 120mm fan setup improve performance over single-fan coolers?
Two 120mm PWM fans deliver a wider RPM range, allowing independent speed control that balances noise and cooling performance across different workload scenarios.
Can I use this cooler in a gaming and productivity workstation hybrid build?
Yes, the performance-oriented design with dual fans and extra-thick radiator handles both gaming loads and CPU-intensive tasks like video editing or data processing.
What is the UltraFine Microchannel water block?
This copper water block features advanced microchannel geometry that maximizes water contact surface area, extracting more heat from high-performance CPUs.
Does this cooler work with both Intel and AMD platforms?
Yes, the Seidon 120XL includes mounting hardware for both Intel and AMD socket types.
Is maintenance required during the cooler's lifetime?
No, the sealed loop design requires zero maintenance throughout its operational lifespan.
What are typical delivery times for this performance cooler in the UAE?
Lead times depend on inventory levels and your location in the UAE or wider GCC. Procure.ae will provide a quote with expected delivery when you request one.
Do you offer installation support for high-performance coolers like this?
Procure.ae can advise on installation and answer setup questions for performance builds. Contact the team to discuss your specific requirements.
What is the radiator thickness and why does it matter?
The 38mm radiator thickness provides significantly more surface area for heat dissipation, allowing better cooling of high-wattage CPUs compared to standard thin radiators.
Are there any special mounting requirements for this cooler?
Standard Intel and AMD socket mounting is provided, though the dual fans and larger radiator benefit from larger cases. Contact Procure.ae to confirm compatibility with your specific chassis.
What differentiates the 120XL from other Seidon 120mm coolers?
The 120XL stands out with its extra-thick 38mm radiator, dual 120mm fans with wide RPM adjustment, and UltraFine Microchannel water block for high-performance CPU cooling.
