This thermalright vs GDSTIME case fan comparison looks at two slim cooling options for small spaces. Both brands offer ultra-thin designs suitable for tight CPU coolers or compact cases. The main difference lies in their physical size and control methods. One provides a larger 92mm frame with PWM speed adjustment, while the other uses a smaller 70mm frame with direct DC voltage control. You need to match the fan dimensions and connector type to your motherboard and case layout for proper installation.

Which one should you choose?
Choose Thermalright 92mm Slim PWM Fan if
- You need automatic speed control via your motherboard
- Your case or cooler requires a 92mm mounting hole pattern
- You prioritize higher airflow and lower noise levels
Choose GDSTIME 70mm 3-Pin Cooling Fan 2-Pack if
- You are replacing a fan in a legacy 70mm slot
- Your motherboard only provides 3-pin DC headers
- You need a fan that operates on a fixed voltage range
Verdict: The Thermalright fan suits users with modern motherboards who want efficient, quiet cooling with automatic speed management. The GDSTIME option is better for older systems or specific 70mm spaces where PWM control is unavailable. Choose based on your available mounting size and header type.
Fan Size and Control Comparison
Physical dimensions
The Thermalright TL-9015 measures 92 by 92 by 15 mm. This larger frame allows it to move more air across a wider area. The GDSTIME model is significantly smaller at 70 by 70 by 15 mm. You must check your case or cooler clearance carefully. The 92mm fan fits standard 92mm mounts, while the 70mm unit requires a specific 70mm hole. If you have a standard small case, the Thermalright option offers more versatility. The GDSTIME fan is strictly for tight 70mm slots. Size matters for fitment, so verify your mounting holes before choosing.
Airflow performance
Airflow determines how much cool air reaches your components. The Thermalright fan pushes 42.58 CFM at its maximum speed. This higher volume helps dissipate heat from dense CPU coolers or radiators. The GDSTIME fan provides 18.7 CFM. While sufficient for small heatsinks, it moves less air overall. If you prioritize maximum cooling capacity, the Thermalright unit is the stronger choice. The GDSTIME fan is adequate for basic cooling needs in very small enclosures. Higher airflow usually means better thermal headroom for your processor.
Noise levels
Noise output varies based on speed and bearing type. The Thermalright fan operates at or below 22.4 dBA. It uses a liquid bearing to reduce friction and vibration. The GDSTIME fan reaches 25.8 dBA at its rated speed. It uses a sleeve bearing, which is standard but can wear over time. The Thermalright unit is quieter by about 3.4 dBA. This difference is noticeable in a quiet room. If low noise is your priority, the Thermalright fan offers a smoother, quieter operation.
Motherboard control
Control methods affect how the fan responds to temperature changes. The Thermalright TL-9015 uses a 4-pin PWM connector. This allows your motherboard to automatically adjust speed based on thermal readings. The GDSTIME fan uses a 3-pin DC connector. It runs at a fixed speed determined by voltage. You cannot easily vary its speed via software. PWM control offers better efficiency and silence at low loads. If you want automatic speed management, the Thermalright fan is the clear winner.
Bearing and lifespan
Bearings impact longevity and maintenance. The Thermalright fan features a liquid bearing design. This type typically offers smoother operation and longer life than traditional sleeve bearings. The GDSTIME fan uses a sleeve bearing. It is rated for 35,000 hours at 25 degrees Celsius. Sleeve bearings are common but may generate more noise as they age. The liquid bearing in the Thermalright unit aims for lower noise and extended durability. For long-term reliability, the Thermalright bearing type is superior.
Choose the right fan for you
Users needing strong airflow for CPU cooling
The Thermalright TL-9015 delivers 42.58 CFM of air movement, which is more than double the GDSTIME output. Its 92mm frame covers a larger surface area. The 4-pin PWM connector allows your motherboard to adjust speed based on temperature. This automatic control helps maintain efficient cooling without manual intervention or noise spikes.
Owners of small 70mm slot cases
The GDSTIME fan fits into tight 70 by 70 mm spaces where larger fans cannot go. It includes two units for easy replacement or dual setups. The 3-pin connection works with standard DC headers. Its compact size allows you to install it in mini-ITX builds or inside small form factor chassis where space is extremely limited.
Users prioritizing quiet operation in PCs
Noise levels matter for comfortable computing. The Thermalright fan operates at 22.4 dBA, which is quieter than the GDSTIME option. Its liquid bearing design helps reduce friction and vibration. This results in smoother running and lower acoustic output. You get better silence while still maintaining high airflow for your system components.

Frequently asked questions
Can I use the Thermalright fan for PWM speed control?
Yes, the Thermalright TL-9015 uses a 4-pin connector. This allows your motherboard to adjust the fan speed automatically based on temperature. You get quiet operation at low loads and stronger cooling when needed. This makes it suitable for modern systems that support PWM control.
Does the GDSTIME fan support automatic speed adjustment?
No, the GDSTIME GDT7015S12V3P uses a 3-pin connector. It runs at a fixed speed determined by the voltage supplied. It does not support PWM control, so you cannot adjust the speed via your motherboard software. It is best for legacy systems or direct 12V connections.
Which fan is better for a CPU cooler with tight clearance?
The Thermalright TL-9015 is ideal for tight clearances. Its 92mm frame and 15mm thickness fit well on many CPU coolers. The GDSTIME 70mm model is also 15mm thick but smaller. Choose the Thermalright if you need more airflow. Choose the GDSTIME only if your cooler requires a 70mm footprint.
What is the size difference between these two fans?
The Thermalright fan measures 92 by 92 by 15 mm. The GDSTIME fan is smaller at 70 by 70 by 15 mm. Both share the same 15mm thickness. The Thermalright covers a larger area, which helps move more air. The GDSTIME fits in tighter spaces where a 92mm fan will not fit.
Is the GDSTIME fan suitable for modern PC builds?
It is not suitable for modern PWM-controlled systems. The GDSTIME fan uses a 3-pin connector and lacks PWM support. Modern motherboards expect PWM fans for precise speed control. Use this fan only for older systems or if you need a direct 12V replacement for a legacy CPU cooler.
Can I mount the Thermalright fan on a standard case?
The Thermalright TL-9015 is designed primarily for CPU coolers and tight spaces. Its 92mm size may not fit standard 120mm or 140mm case fan mounts. It works well in compact cases or on coolers with 92mm mounting holes. Check your case or cooler specifications before purchasing for general case airflow.
Do these fans come with mounting hardware?
The product data does not specify included mounting hardware. You should check the packaging or product description for screws or anti-vibration pads. Both fans are designed for specific mounting patterns. Ensure your cooler or case supports the 92mm or 70mm hole spacing before relying on included accessories.
