Are you looking to replace the fan on your Enermax ETS-T50 cooler? You've come to the right place! The Enermax ETS-T50 is a great CPU cooler, known for its performance and relatively quiet operation. But, like any fan, the one on your ETS-T50 can eventually wear out, become noisy, or even fail. When that happens, you'll need to find a suitable replacement to keep your CPU running cool and prevent overheating. Finding the perfect replacement fan doesn't have to be a headache. This guide walks you through everything you need to know to get your cooler back in top shape.

Understanding Your Enermax ETS-T50 Fan

Before you rush out and buy just any fan, it's important to understand the specifications of the original fan that came with your Enermax ETS-T50. This will ensure that the replacement fan you choose is compatible and provides similar or better performance.

• Fan Size: The Enermax ETS-T50 typically uses a 120mm fan. This is a standard size for CPU coolers, so you'll have plenty of options to choose from. However, double-check your specific model to be absolutely sure. Using the correct size is crucial for proper fitment and airflow.
• Fan Thickness: Most 120mm fans are 25mm thick. This is another common standard, but it's always wise to confirm. A thicker fan might offer slightly better performance, but could also cause clearance issues with your case, RAM, or other components. A thinner fan might not provide enough cooling power.
• Connector Type: CPU cooler fans typically use a 4-pin PWM (Pulse Width Modulation) connector. This allows the motherboard to control the fan speed based on the CPU temperature. Some older fans might use a 3-pin connector, which provides voltage-based speed control. While a 3-pin fan can work in a 4-pin header, you'll lose the automatic speed control feature. A 4-Pin PWM connector is almost always better for optimal cooling and noise levels.
• Voltage: Almost all case and CPU cooler fans operate at 12V DC. This is the standard voltage for PC components, so you likely won't need to worry about this.
• Airflow (CFM): Airflow is measured in CFM (Cubic Feet per Minute) and indicates how much air the fan can move. A higher CFM generally means better cooling performance, but it can also mean more noise. Consider the original fan's CFM rating as a baseline. If you're aiming for better cooling, look for a fan with a higher CFM. If you prioritize silence, choose a fan with a similar or slightly lower CFM.
• Static Pressure (mmH2O): Static pressure is the fan's ability to push air through obstructions, like the fins of a CPU cooler. Higher static pressure is important for CPU coolers to effectively dissipate heat. Check the original fan's static pressure rating and choose a replacement with a similar or higher rating.
• Fan Speed (RPM): Fan speed is measured in RPM (Revolutions Per Minute) and indicates how fast the fan blades spin. A higher RPM generally means more airflow and cooling, but also more noise. PWM fans allow the motherboard to dynamically adjust the fan speed based on temperature, providing a balance between cooling and noise.
• Noise Level (dBA): Noise level is measured in dBA (decibels) and indicates how loud the fan is. Lower dBA values mean quieter operation. If noise is a concern, look for a fan with a low dBA rating. Keep in mind that noise levels are often subjective and can vary depending on the testing environment.
• Bearing Type: The fan's bearing type affects its lifespan, noise level, and price. Common bearing types include sleeve, ball, and fluid dynamic bearings. Fluid dynamic bearings (FDB) generally offer the best balance of performance, lifespan, and noise.

Finding the Right Replacement Fan

Now that you know what to look for, let's explore how to find the right replacement fan for your Enermax ETS-T50. Here are a few options to consider:

Option 1: Identical Replacement

The easiest option is to find an identical replacement fan. This guarantees compatibility and similar performance. Check the Enermax website or online retailers to see if you can purchase the exact same fan model that came with your cooler. This eliminates any guesswork and ensures a perfect fit.

Option 2: Aftermarket Fans

If you can't find an identical replacement, or if you're looking for an upgrade, you can explore aftermarket fans from other manufacturers. Many companies make high-quality 120mm fans that are compatible with CPU coolers. When choosing an aftermarket fan, pay close attention to the specifications mentioned earlier (CFM, static pressure, noise level, etc.) to ensure it meets your needs.

Popular aftermarket fan brands include:

• Noctua: Known for their high-performance, quiet fans. They are often considered the gold standard in PC cooling.
• Corsair: Offers a wide range of fans with different features and price points.
• be quiet!: Specializes in silent PC components, including fans.
• Arctic: Provides excellent value for money with their affordable and effective fans.
• Cooler Master: Offers a variety of fans with different styles and features.

Option 3: Consider RGB (Optional)

If you're into aesthetics, you might consider a replacement fan with RGB lighting. These fans add a visual flair to your system. Make sure the RGB fan is compatible with your motherboard's RGB control system (e.g., ASUS Aura Sync, MSI Mystic Light, GIGABYTE RGB Fusion, ASRock Polychrome Sync).

Step-by-Step Replacement Guide

Once you've got your replacement fan, here's how to install it:

1. Power Down: Turn off your computer and unplug it from the power outlet. This is crucial for safety.
2. Open Case: Open your computer case to access the CPU cooler.
3. Disconnect Old Fan: Disconnect the old fan's power cable from the motherboard.
4. Remove Old Fan: The fan is usually attached to the cooler with clips or screws. Carefully remove the clips or unscrew the fan.
5. Install New Fan: Attach the new fan to the cooler using the same clips or screws. Make sure the fan is oriented correctly, so it blows air in the right direction (usually towards the heatsink).
6. Connect New Fan: Connect the new fan's power cable to the motherboard's CPU fan header.
7. Close Case: Close your computer case.
8. Power On: Plug in your computer and turn it on.
9. Monitor Temperatures: Monitor your CPU temperatures to ensure the new fan is working correctly. You can use monitoring software like HWMonitor or the motherboard's BIOS.

Tips for Optimal Cooling and Noise Reduction

Here are a few extra tips to help you achieve the best cooling performance and minimize noise:

• Clean the Heatsink: Before installing the new fan, clean the heatsink fins with compressed air to remove any dust or debris. This will improve airflow and cooling performance. Over time, dust can build up and insulate the heatsink, reducing its effectiveness.
• Manage Cables: Make sure the fan cable is neatly routed and doesn't interfere with the fan blades. This will prevent noise and ensure optimal airflow. Use zip ties or cable ties to keep the cable out of the way.
• Adjust Fan Speed: Use your motherboard's BIOS or fan control software to adjust the fan speed curve. This will allow you to balance cooling performance and noise levels. Experiment with different fan speed settings to find the sweet spot for your system.
• Consider a Fan Controller: If you want more control over your fan speeds, you can invest in a dedicated fan controller. This allows you to manually adjust the fan speeds or create custom fan curves.
• Check Airflow: Ensure that your case has good airflow to help dissipate heat. Make sure there are intake fans bringing cool air into the case and exhaust fans removing hot air. Proper case airflow is crucial for overall system cooling.

Troubleshooting Common Issues

If you encounter any problems after replacing the fan, here are a few things to check:

• Fan Not Spinning: Make sure the fan is properly connected to the motherboard's CPU fan header. Also, check the BIOS settings to ensure the fan is enabled and the fan speed is set appropriately. Sometimes, the fan header might be disabled in the BIOS by default.
• High Temperatures: If your CPU temperatures are still high after replacing the fan, make sure the fan is oriented correctly and blowing air towards the heatsink. Also, double-check that the heatsink is properly mounted to the CPU and that there is adequate thermal paste. Reapplying thermal paste might be necessary.
• Loud Noise: If the new fan is making excessive noise, check for any obstructions or loose cables that might be interfering with the fan blades. Also, make sure the fan is securely mounted to the heatsink. Sometimes, a loose fan can vibrate and cause noise.
