The Deepcool Lt720 is a popular all-in-one liquid CPU cooler known for its performance and sleek design. Recently, testing was conducted to evaluate its pump and fan noise levels under various conditions. This review summarizes the results of those tests, providing insights for enthusiasts and builders concerned about noise levels.
Overview of the Deepcool Lt720
The Lt720 features a 360mm radiator, three high-quality fans, and a robust pump. Its design aims to balance cooling efficiency with minimal noise. Understanding its noise profile is essential for users seeking a quiet computing environment.
Test Setup and Methodology
Tests were conducted in a controlled environment with ambient noise levels of approximately 30 dB. The CPU was subjected to stress tests using Prime95, and noise levels were measured at a distance of 50 cm from the radiator and fans. Sound level meters recorded the pump and fan noise separately during operation.
Fan Noise Testing
The three fans on the Lt720 were tested at different RPM levels: 800 RPM (low), 1500 RPM (medium), and 2000 RPM (high). Results showed:
- At 800 RPM, fan noise was approximately 20 dB, barely audible.
- At 1500 RPM, noise increased to around 30 dB, noticeable but not disruptive.
- At 2000 RPM, fans produced roughly 38 dB, which could be heard clearly in a quiet room.
Pump Noise Testing
The pump’s noise level was measured during high CPU load. Results indicated:
- At idle, the pump emitted about 15 dB, almost inaudible.
- Under load, the pump’s noise increased to approximately 25 dB.
- During maximum load, the pump produced around 28 dB, blending into the overall noise but remaining unobtrusive.
Overall Noise Profile and User Experience
The combined noise of the Lt720 at medium fan speeds is generally acceptable for most users, especially in a typical office or gaming setup. At high speeds, noise levels become more noticeable but still remain within a comfortable range for many enthusiasts. The pump’s quiet operation at idle and under load contributes positively to the overall experience.
Conclusion
The Deepcool Lt720 offers impressive cooling performance with relatively low noise levels. Its fans and pump operate quietly at moderate speeds, making it suitable for users prioritizing a quiet PC build. For overclockers or users who frequently run their systems under heavy load, the noise increase at maximum speeds is manageable and does not significantly detract from the overall experience.
