Looking Beyond the Thermalright 80mm PWM Cooling Fan? 6 Alternatives Worth a Look

How each alternative compares

Thermalright 92mm Slim PWM Fan

The Thermalright TL-9015 swaps the standard 25mm thickness for a 15mm slim profile. This 92x92x15mm design offers a narrower footprint than the 80mm TL-B8, making it better for tight CPU coolers or compact cases where depth is restricted. While the TL-B8 focuses on 34 CFM airflow in a standard frame, the TL-9015 prioritizes fitting into smaller spaces. Both use 4-pin PWM connectors for automatic speed control. You should choose this slim alternative if your build has limited vertical clearance for fans, even though the fan diameter increases slightly to 92mm.

Thermalright 120mm Slim ARGB Fan

The Thermalright TL-C12015W-S expands your options with a 120mm size and ARGB lighting, which the plain TL-B8 lacks. This 120x120x15mm fan adds visual appeal for builds that want visible effects, while still maintaining a slim 15mm depth. It is larger than the 80mm TL-B8, so it fits different mounting spots. The 4-pin PWM interface ensures you still get automatic speed regulation based on system temperatures. If you need more airflow surface area and want lighting, this 120mm model is a strong upgrade, provided your case supports the larger dimensions and has ARGB headers.

Thermalright 80mm PWM Case Fan

The Thermalright TL-B8W is a direct sibling to the original TL-B8, sharing the same 80mm dimensions and 4-pin PWM connectivity. It serves as a quiet ventilation option for standard 80mm slots, similar to the TL-B8. The key difference lies in the specific model variations, which may offer slight aesthetic or minor spec tweaks not detailed here. It remains a practical choice for builders prioritizing low noise and bearing durability over high static pressure. If you need another 80mm fan that matches the original's form factor and quiet operation, this alternative provides a reliable, consistent performance profile for standard case ventilation.

Thermalright 80mm Slim PWM Fan

The Thermalright TL-8015 maintains the 80mm footprint but reduces the thickness to 15mm, unlike the 25mm TL-B8. This slim profile is ideal for tight mounts where standard fans do not fit. It delivers quiet, low-profile airflow without the bulk of the original. Both fans use 4-pin PWM connectors for speed control. You should pick the TL-8015 if your case or CPU cooler requires a thinner fan installation. It sacrifices some depth for the ability to fit in restricted spaces, making it a specialized choice for compact builds that still need reliable 80mm fan compatibility.

ASUS ROG Strix XF120 120mm PWM Fan 2-Pack

The ASUS ROG Strix XF120 shifts to a 120mm size and is sold as a 2-pack, offering more cooling surface than a single 80mm fan. It is designed for silent radiator and CPU cooling, focusing on bearing durability and stable airflow. Unlike the TL-B8, it lacks ARGB lighting, prioritizing function over form. The 4-pin PWM connector ensures automatic speed control. Choose this alternative if you need to cool a radiator or require more airflow area. It is better for standard 120mm mounts rather than the smaller 80mm slots used by the original TL-B8.

Thermalright 120mm Slim PWM Fan

The Thermalright TL-C12015B D6 is a 120mm slim fan with a 15mm depth, combining larger size with a low profile. It fits users with tight clearance who need reliable airflow without excessive noise. Unlike the 80mm TL-B8, this model covers a larger area, making it suitable for shallow cases or slim coolers. It uses a 4-pin PWM connector for speed regulation. If you need more cooling capacity than the 80mm fan provides but still have limited depth, this 120mm slim option is a practical solution. It offers a balance of size and thinness for modern compact builds.
