Looking Beyond the Thermalright C12015W-S CPU Fan Computer? 6 Alternatives Worth a Look
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
If you are searching for thermalright c12015w s cpu fan computer alternatives, you likely need cooling gear tailored to specific clearance or performance requirements. The original Thermalright TL-C12015W-S performs well in space-constrained enclosures thanks to its 15mm slim profile. It provides up to 52 CFM airflow and 1.24 mm H2O static pressure at a maximum speed of 1500 RPM, keeping noise output at or below 24.1 dBA while offering addressable RGB lighting and 4-pin PWM control.
You might still require different specifications for your build. You may need higher rotational speeds for increased cooling, reverse fan blades for visible intake setups, daisy-chain connectors to reduce cable clutter, or standard 25mm frames featuring fluid dynamic bearings. The 6 alternatives in this guide were chosen because their specifications directly overlap with the original unit, featuring 120mm mounting footprints, 4-pin PWM connections, and ARGB lighting for CPU cooler or chassis cooling.
Our top pick: Thermalright 120mm Slim ARGB Fan.
Comparing Alternatives to the Thermalright C12015W-S
Thermalright 120mm Slim White ARGB Fan
The Thermalright TL-H12015W-S matches the original fan with a slim 15mm (0.59-inch) frame, 120mm size, and 4-pin PWM ARGB connectivity. It increases rotational velocity up to 1900 RPM, giving you higher speed headroom than the 1500 RPM cap on the TL-C12015W-S. This higher speed ceiling pushes more air through dense cooling fins, though faster rotation naturally generates more audible output than the original fan's 24.1 dBA limit. You give up the specific low-noise tuning of the 1500 RPM original profile. Choose this model if your compact case has tight clearances and requires a white color scheme with elevated fan speeds.
darkFlash 120mm Reverse ARGB Fan
The darkFlash INF34 differs from the original by using a full-thickness 0.98-inch (25mm) casing instead of a slim 0.59-inch profile. It features reverse-pitch fan blades and interlocking pin connectors, letting you route intake airflow while displaying the clean front side of the frame with minimal wiring. In exchange, you lose the tight-space clearance of the 15mm Thermalright fan, making it unsuitable for low-profile CPU coolers or cramped brackets. It also comes as a larger three-fan unit weighing 1.41 pounds. Choose this model if your chassis accommodates standard 25mm fans and you want reverse airflow for visible intake mounts.
Empowered PC 120mm Reverse ARGB Fan 3-Pack
The Empowered PC V2R kit supplies three reverse-blade fans rather than a single forward-flow unit. It provides a wide PWM control curve running from 600 RPM up to 1600 RPM, giving you a slightly higher top speed and lower idle speeds compared to the original 1500 RPM fixed-top ceiling. The reverse blade orientation allows you to run intake configurations without showing rear motor braces. However, you give up the compact 15mm height of the TL-C12015W-S, requiring full case clearance to mount the thicker frames. Pick this three-pack if you need multiple visible intake fans for your chassis or radiator.
LDPCSJ 120mm Slim ARGB Fan 3-Pack
The LDPCSJ 3-Pack retains the 15mm (0.59-inch) slim thickness of the original Thermalright fan, preserving compatibility with space-constrained brackets and compact CPU coolers. It substantially raises operating performance by scaling up to 2400 RPM, far exceeding the 1500 RPM maximum of the TL-C12015W-S to deliver stronger static pressure and airflow. Running at 2400 RPM produces noticeably more acoustic output than the original fan's quiet 24.1 dBA threshold. You also receive three fans instead of one. Choose this bundle if you have strict clearance limits in a small-form-factor case and need maximum cooling throughput regardless of added sound.
Cooler Master MF120 Halo 120mm ARGB Fan
The Cooler Master MasterFan MF120 Halo uses a standard 0.98-inch (25mm) housing, making it significantly thicker and heavier at 7.05 ounces compared to the 3.53-ounce, 15mm Thermalright unit. It features dual-ring ARGB illumination and a wider PWM band running from 650 to 1800 RPM, granting 300 RPM more headroom than the original fan. What you sacrifice is the compact 0.59-inch slimness required for clearance-limited mini-ITX cases or low-profile heatsinks. Choose the MF120 Halo if your computer case has ample room for conventional 25mm fans and you want dual-ring lighting effects with flexible speed control.
Thermalright 120mm White ARGB Fan 3-Pack
The Thermalright TL-C12CW-S X3 D6 pack delivers 66.17 CFM of airflow, which surpasses the 52 CFM rating of the original TL-C12015W-S. It also incorporates fluid dynamic bearings and daisy-chain connectors for simpler multi-fan cable routing. However, this model measures 0.98 inches (25mm) in thickness, adding nearly half an inch of depth over the 0.59-inch slimline frame of the original. It will not fit into cramped clearance gaps between radiators, RAM modules, or mini-ITX brackets. Select this three-pack if you have room for standard 25mm fans and need higher airflow with durable fluid bearings.

Frequently asked questions
Which slim alternatives match the 15mm thickness of the Thermalright TL-C12015W-S?
You can choose between the Thermalright TL-H12015W-S and the LDPCSJ 120mm Slim ARGB Fan 3-Pack. Both models measure 0.59 inches (15mm) thick, fitting low-clearance mounts that standard fans cannot clear. The TL-H12015W-S reaches 1900 RPM, while the LDPCSJ model operates up to 2400 RPM with PWM control and addressable lighting.
What is the benefit of choosing a reverse blade fan over a standard slim fan?
Reverse blade fans direct airflow inward while keeping the visible front side of the fan facing you. Models like the darkFlash INF34 and Empowered PC V2R act as intake fans without exposing rear support struts. However, they use standard 0.98-inch frames, making them thicker than the 0.59-inch frame found on the Thermalright TL-C12015W-S.
Can you replace a slim 15mm CPU fan with a standard 25mm thick model?
You can replace a slim fan with a 25mm fan only if your case or cooler has at least 0.98 inches of physical clearance. Standard options like the Cooler Master MF120 Halo and Thermalright TL-C12CW-S provide 0.98-inch depth. Before switching, measure your memory clearance and case width to verify that the thicker housing will fit.
Which alternative offers the highest maximum rotational speed for cooling?
The LDPCSJ 120mm Slim ARGB Fan delivers the highest rotational ceiling on this list with a top speed of 2400 RPM. This model pairs 2400 RPM PWM control with a 15mm slim build. In comparison, the Thermalright TL-H12015W-S runs up to 1900 RPM, while the Cooler Master MF120 Halo tops out at 1,800 RPM.
Which listed fan options feature fluid dynamic bearings?
The Thermalright TL-C12CW-S X3 D6 3-Pack includes a fluid dynamic bearing for its rotating assembly. This standard 0.98-inch white fan provides up to 66.17 CFM of airflow alongside addressable lighting. Its 4-pin PWM daisy-chain design allows you to regulate speeds across multiple fans while maintaining smooth bearing operation in standard 120mm fan slots.
How do daisy-chain fan options help with cable management?
Daisy-chain designs simplify cable runs by linking fans together instead of routing individual wires to your motherboard. For example, the darkFlash INF34 uses interlocking pins to connect fans and pass lighting and power through a single cable. Similarly, the Empowered PC V2R 3-Pack and Thermalright TL-C12CW-S utilize daisy-chain connections for simpler PWM wiring.
What connector types do these alternative fans require on your motherboard?
Every alternative listed here features a 4-pin connector to support PWM fan speed regulation. This allows your motherboard or fan controller to adjust motor speeds dynamically based on heat. For RGB effects, these fans use addressable RGB connections, such as the 5V 3-pin ARGB connector specified for the Cooler Master MF120 Halo.
