Specifications side by side

MITXPC Heatsinks: 6 Picks Ranked by Specs

The lineup splits into passive and active cooling groups. The Dynatron LGA4189 Copper Heatpipe Heatsink and Dynatron Threadripper and EPYC CPU Cooler use fans for 270W and 280W TDP loads. These suits users needing active dissipation for high-power processors. The MITXPC Threadripper EPYC Passive 2U Heatsink and Dynatron 1U AM4 Copper Passive Heatsink rely on case airflow. They fit silent server builds where fans are absent or unwanted.

Socket compatibility defines the second split. The MITXPC LGA 1700 Heatsink and PWM Fan targets compact desktops with 125W chips. The MITXPC 1U Intel LGA4710 Liquid Cooler handles 350W in tight 1U spaces. You choose based on your socket type and chassis height. Passive models require strong case fans. Active units include pre-mounted hardware for immediate installation.

Where MITXPC Fits

MITXPC targets specific form factors and sockets. The range spans from compact 1U passive copper blocks for AM4 to large 2U server solutions for Threadripper and EPYC. You will find active coolers for LGA4189 and LGA1700, plus a 1U liquid option for LGA4710. Sizes vary from narrow 2.5-inch widths to 4-inch footprints. The brand focuses on server heights and high TDP handling. You will not find consumer-oriented RGB lighting or universal socket compatibility. The lineup is narrow, excluding standard ATX tower coolers. It suits builders with constrained vertical space or specific server chassis needs.

How to Choose the Right Heatsink

1. Match the Processor Socket

   You must ensure the heatsink base fits your specific CPU socket. The Dynatron LGA4189 Copper Heatpipe Heatsink supports FCLGA4189 processors, while the Q5 model is designed for LGA 1700. The AM4 Copper Passive Heatsink is built for AM4 sockets. Selecting the wrong socket compatibility means the unit will not mount correctly. Check the socket compatibility field in the specifications before purchasing to avoid installation failures.

2. Check the System Form Factor

   Your chassis height determines which cooler you can install. The A37 AM4 Copper Heatsink is a 1U model, meaning it is only one unit high. The Threadripper EPYC Passive Heatsink is a 2U model, which is taller. You must measure your case clearance to ensure the heatsink fits vertically. If you have a 1U server, you cannot use the 2U Threadripper option. Always compare the height spec against your available space.

3. Decide on Active or Passive

   Passive heatsinks rely on case airflow, while active ones include fans. The A37 and the Threadripper EPYC Passive Heatsink are passive units. They require you to provide adequate airflow from case fans. The LGA4189 Copper Heatpipe Heatsink and the Q5 LGA 1700 model include fans. Choose passive for silent operation if your case has strong airflow. Choose active if you need guaranteed cooling performance without relying on case fans.

4. Verify Thermal Design Power

   You need a cooler that can handle your CPU's heat output. The Dynatron LGA4189 model supports up to 270W TDP. The A39 Threadripper Heatsink handles 280W TDP. The Q5 LGA 1700 model is rated for 125W. If your processor exceeds the heatsink's rated TDP, it will overheat. Match your CPU's TDP to the cooler's capacity. Do not assume a larger heatsink handles more heat without checking the specific rating.

5. Consider Material and Weight

   Copper conducts heat better than aluminum, but it is heavier. The A37 AM4 heatsink is made of copper, which aids passive cooling. The LGA4189 model uses copper heatpipes and aluminum fins. The Q5 LGA 1700 model weighs one pound. Heavier units may require stronger mounting hardware. Check the material composition to understand thermal performance. Also, verify the weight to ensure your motherboard can support the load without sagging.
