Our Tests
Contents
We ran some simple tests to check the performance of the Deepcool V4000, measuring the GPU core temperature with the aid of the SpeedFan software, and sound pressure level (SPL) with a digital noise meter set 4" (10 cm) from the video card, with the GPU at full load running the [email protected] GPU client. For this measurement, we turned off the fans of the case and the CPU cooler, so they noise wouldn’t interfere. Please keep in mind that sound pressure level measurement is just for comparative purposes, because a precise measurement would have to be done in an acoustically insulated anechoic chamber, which we don’t have.
We compared the results from the V4000 with some other coolers we tested recently, and with the VGA stock cooler. You can check the results in the table below.
| Product | Noise | Room Temp. | Core Temp. | Temp. Diff. | Speed |
| Stock Cooler | 61 dBA | 16 °C | 73 °C | 57 °C | – |
| VF1000 LED (min.) | 44 dBA | 16 °C | 74 °C | 58 °C | 1400 rpm |
| VF1000 LED (max.) | 51 dBA | 16 °C | 61 °C | 45 °C | 2600 rpm |
| Scythe Musashi (min.) | 40 dBA | 16 °C | 65 °C | 49 °C | 850 rpm |
| Scythe Musashi (max.) | 47 dBA | 16 °C | 58 °C | 42 °C | 1950 rpm |
| VF3000A (min) | 47 dBA | 19 °C | 52 °C | 33 °C | 1500 rpm |
| VF3000A (máx) | 57 dBA | 19 °C | 49 °C | 30 °C | 2800 rpm |
| Arctic Cooling Accelero Twin Turbo Pro | 43 dBA | 15 °C | 50 °C | 35 °C | – |
| Gelid Icy Vision | 54 dBA | 15 °C | 66 °C | 51 °C | 2050 rpm |
| Deepcool V4000 | 44 dBA | 21 °C | 70 °C | 49 °C | 1850 rpm |
In the graph below, you can compare the temperature differences between the GPU core and the room. Remember that the lower the value, the better performance is.
