Introduction

In this article, we will be exploring the differences between the Super Micro Super Server 65 Watt 12 Core and the 45 Watt 8 Core. These two systems may appear similar at first glance, but we will be diving deeper into the physical disparities, particularly in terms of fan speed and type. By examining the specifications and performance of these servers, we will better understand the implications of these distinctions.

Physical Differences between the Super Micro Super Server 65 Watt 12 Core and the 45 Watt 8 Core

One of the key variations between the Super Micro Super Server 65 Watt 12 Core and the 45 Watt 8 Core lies in their physical design. Specifically, the fan speed and type play a significant role in differentiating these systems. The original fan used in the 1541 model differs from the one used in the 1567 model. The 1567, being a 12-core server, is taller in height and has a wider fan with a 60mm width, as compared to the 50mm width of the 1541's fan. While the 1567's fan spins at a slower speed, it has the potential to provide a higher CFM (Cubic Feet per Minute) performance.

Spec Comparison: Super Micro Super Server 1567 (12 Core) vs. 1541 (8 Core)

To gain a better understanding of the differences between the 1567 and 1541 models, let's take a closer look at their specifications. Firstly, the 1567 stands out due to its increased height, which is a result of accommodating the 12 cores. Additionally, the 1567 boasts a wider fan with a 60mm width, as compared to the 50mm width of the 1541's fan. This wider fan has the potential to provide a higher CFM, meaning it can move more air per minute. When comparing the fan RPMs, we can see that the 1567 operates at a lower speed but still maintains a reasonable CFM.

Explaining CFM (Cubic Feet per Minute)

CFM, or Cubic Feet per Minute, is a unit of measurement used to quantify the airflow produced by a fan. It represents the volume of air that the fan can move in a minute. The higher the CFM, the greater the amount of air circulated. In the case of the Super Micro Super Servers, a larger fan with a higher CFM could potentially result in improved cooling performance and better heat dissipation.

Task Manager Comparison: 8 Core vs. 12 Core

Now let's take a closer look at the performance of the 8-core and 12-core servers by examining the Task Manager. Both machines exhibit similar specifications, with 16 Threads of execution and logical processors. However, the 12-core server showcases a third more cache in all levels - level 1, level 2, and level 3. This cache increase contributes to improved performance and scalability, making the 12-core server more Adept at handling intensive tasks. Additionally, the gigahertz of the two machines are relatively similar, highlighting the relaxed state these machines operate in when performing minimal tasks.

Supermicro Utility: Super Doctor 5

Super Doctor 5 is a powerful utility offered by Supermicro that allows users to monitor various aspects of their servers. It enables users to view temperatures, fan speeds, and other vital information without the need for manual refreshes. By utilizing this software, users can keep track of the temperatures and fans in the Super Micro Super Servers with ease. With Super Doctor 5, users can ensure optimal performance and take necessary actions to address any issues related to temperature or fan operation.

Testing Fan Speeds and Temperatures

To assess the cooling performance and fan speed of the Super Micro Super Servers, let's conduct some tests. By configuring the fan mode to full speed, we can observe the instantaneous readout of the new RPM. Although it may appear to be a small change, even slight variations in fan speed can impact the overall cooling efficiency of a server. This step allows us to Gather data on the fan speeds and compare them between the two server models.

Prime95 Heat Test: CPU Performance under Maximum Stress

To thoroughly assess the CPU performance of the 8-core and 12-core servers, we will subject them to the Prime95 heat test. This test ensures maximum stress on the CPUs, allowing us to observe the temperature and watt burn differences. By analyzing these factors, we can gain insights into how well the servers handle intensive workloads. Furthermore, we will examine the impact of the fan speed variations on temperature control during the test.

Thermal Characteristics and Aftermarket Fan Replacements

As enthusiasts, we often Seek solutions to optimize the cooling and noise levels of our servers. In this section, we will explore the possibility of replacing the CPU and chassis fans with aftermarket alternatives. Although one might expect these replacements to improve cooling performance, our experimentation with various fans proved otherwise. Despite our efforts to find alternative solutions, the cooling results were subpar compared to the stock fans provided by Supermicro. It is crucial to consider the risks and potential challenges associated with fan replacements, such as surgical procedures, stripped screws, and dealing with thermal paste.

Conclusion and Recommendations

In conclusion, the Super Micro Super Servers, including the 65 Watt 12 Core and the 45 Watt 8 Core models, offer different configurations that cater to varying performance needs. The physical differences, such as fan speed and type, significantly impact the cooling efficiency of these servers. While aftermarket fan replacements may be tempting, our findings suggest that they do not provide substantial improvements and may not justify the associated risks and costs. Nevertheless, the 12-core server might be quieter than the 8-core server, offering users a more pleasant computing experience. It is essential to carefully consider one's specific requirements and priorities when selecting a Super Micro Super Server.
