Cool tips to get the best server cooling fan Server Cooling Fans: Cool Tips for Selecting the Best Fan A server cooling fan is designed to keep server components within their temperature limits during operation. Temperature control ensures optimal performance of the central processing unit (CPU), graphics card, chip sets, hard drives and other components. Selecting a server cooling fan requires knowledge of the technology to select a fan that will cool adequately, quietly and safely. Several tips are offered to help consumers protect their server investment from premature failure of parts due to overheating:
Tip 1: Select a Fan with Maximum Heat Exchange Consumers are advised to select a fan that increases the heat exchange process. The faster the fan displaces the hotter air for cooler air, the more effective the fan is in cooling the server and protecting the essential components. A server cooler fan with a large number of revolutions per minute (RPM) will be more apt to facilitate this process faster. In general, a premium server fan yields between 1800 RPM and 2500 RPM to adequately cool the CPU. Most server cooling fans require more than the fan alone to adequately cool the CPU unit.
Tip 2: Select Fans with Efficient Heat Sinks and the Thermo Electric Cooling Technique Heat sinks are designed to increase the surface area that dissipates heat so the devices are not directly affected by the heat generated. CPU cooling fans have built-in passive heat sinks to facilitate this process. Fans are active heat sinks; however, the fan alone does not adequately control heat. Both passive heat sinks and fans work together to control the temperature near essential components. Effective passive heat sinks are typically made of copper.
Consumers should keep in mind that dust build-up will reduce the efficiency of a heat sink over time. The dust may act as a thermal insulator, impede airflow and fan performance. Gas dusters are recommended to free the fan and heat sink of unwanted dust and other materials.
Tip 3: Select Maximum Moisture Control A cooling fan with thermo-sensors will help to control moisture condensing problems that may occur from water cooling systems or other systems. This method is safer and more efficient than other methods of cooling. Select a fan with this technology for the best results.
Tip 4: Select Maximum Noise Control Passive heat sinks control noise but are not as effective as other technologies. Passive heat sinks combined with a cooling fan are most effective. Some fans have a lower noise rating than others. Select a fan with a low noise rating to minimize noise or humming sounds.
Tip 5: Combine Three Technologies for Maximum Heat Dissipation Premium server cooling fans combine both passive and active heat sinks for maximum cooling. A cold plate with maximum surface area is mounted to dissipate heat from the CPU. A liquid pump is used to pump cool water into the system to make the plate cold. The fan then blows the cool air onto the CPU unit to keep it cool. This type of device is one of the best on the market for cooling servers and CPU units.
Ideal devices are pre-filled with liquid and require no maintenance. Copper CPU cooling plates are recommended for maximum cooling performance.
Tip 6: Select a Fan with a Long Lifetime, Minimum Replacement and Warranties Ensure the device will perform optimally while operating 24 hours per day and seven days per week. Some devices are guaranteed for 70,000 hours or more of operation. Other devices will offer two year warranties on parts and labor. The more assurance the customer has, the less likely the device will malfunction within a short period of time.
