Dimension comparison
Price Comparison
The Thermalright PS120SE CPU Air Cooler is priced at $35.90, while the Thermaltake Gravity i3 comes in at $17.79, making it about 50% cheaper than the Thermalright model. For those on a budget, the Gravity i3 offers significant savings. The price difference can be a deciding factor for users who need a basic cooling solution without breaking the bank.
Cooling Performance
When it comes to cooling performance, the Thermalright PS120SE excels with a TDP (Thermal Design Power) rating of 105W to 280W, designed to handle more demanding CPUs. In contrast, the Thermaltake Gravity i3 is optimized for processors with up to 95W of power, making it less suitable for high-performance applications. The PS120SE also benefits from a dual 120mm fan setup, achieving an airflow of 66.17 CFM, compared to the Gravity i3's maximum airflow of 56.84 CFM. If you're looking for superior cooling for more powerful CPUs, the PS120SE is the clear choice.
Size and Compatibility
The Thermalright PS120SE measures 125(L)x135(W)x154(H)mm and is compatible with a wide range of Intel and AMD socket types, including LGA1700 and AM4. The Gravity i3, on the other hand, has a low-profile design with dimensions of 65.4 H * 96.6 W * 96.6 L mm, making it suitable for compact builds. However, it's primarily designed for LGA 1700 and 1851 sockets. If space is a concern and you're working with a lower wattage CPU, the Gravity i3's compact size might be more advantageous.
Noise Levels
The Thermalright PS120SE operates at a maximum noise level of 25.6 dB(A), which is relatively quiet for high-performance cooling. The Gravity i3, while also designed for low noise, has a higher noise level of 36.5 dBa at maximum fan speed. For users sensitive to noise, the PS120SE presents a better option, particularly in environments where silence is essential, such as home offices or gaming setups.
Installation Ease
Both coolers are designed for easy installation, but the Gravity i3 emphasizes quick and straightforward setup. It features a low-profile design that facilitates installation even in tight spaces. The Thermalright PS120SE, while compatible with various CPU slots, may require more time to install due to its larger size and additional components. If you're less experienced with PC builds or want a hassle-free installation, the Gravity i3 may be the more appealing option.
Build Quality and Durability
The Thermalright PS120SE is built with high-quality materials, including a combination of aluminum and pure copper. It boasts a lifespan of up to 20,000 hours, thanks to its S-FDB bearings, making it robust for long-term use. In comparison, the Gravity i3 has a fan life of 40,000 hours, which is impressive, but the overall build quality may not match the sturdiness of the PS120SE. If durability and long-term performance are your priorities, the PS120SE is likely the better investment.
Brand Reputation
Both Thermalright and Thermaltake have established reputations in the cooling market. Thermalright has over 20 years of experience and is known for its high-performance cooling solutions. Thermaltake also has a solid presence, especially in the case and cooling market. However, Thermalright's focus on CPU coolers might give it an edge in expertise. When choosing a cooler, brand reputation can play a significant role in consumer confidence.
Which should you buy?
Ultimately, the choice between the Thermalright PS120SE and the Thermaltake Gravity i3 depends on your specific needs. If you require high-performance cooling for demanding CPUs, the PS120SE, priced at $35.90, is an excellent option with superior cooling capabilities and durability. However, if you're looking for a budget-friendly solution that offers decent cooling for lower wattage processors, the Gravity i3 at $17.79 is a sensible choice.
