The unit supports Intel LGA1155 and LGA1156 sockets, covering older Core i5, i7, and Xeon processors. Weighing 300 grams, it uses skived fins to maximize surface area within its small footprint. This design prioritizes low profile compatibility over massive cooling capacity.
What stands out
- 1U server height at 26.5 mm fits tight chassis
- Aluminum construction with skived fins for efficiency
- Supports LGA1155 and LGA1156 sockets
- Compact 95 x 95 mm base footprint
Who it fits
Good fit for
You should choose this cooler if you are building a low-profile server or a small form factor PC using older Intel hardware. It suits users who need a reliable passive or low-profile active solution for LGA1155 or LGA1156 CPUs. It is ideal for environments where case height is severely limited, such as in 1U rackmount cases. If you are running older Xeon or Core i series processors and need a fit that respects strict dimensional constraints, this unit delivers the necessary physical compatibility.
Who should skip it
You should look elsewhere if you are using modern CPU sockets like LGA1700 or AM5. This cooler does not support newer platforms, making it obsolete for current generation builds. Additionally, if you require high thermal performance for overclocking or heavy rendering tasks, the small 26.5 mm height and aluminum mass will struggle. It is not suitable for high-TDP processors that demand larger heat sinks and more robust cooling solutions than this 1U unit can provide.
Verdict: This is a specialized component for legacy Intel sockets in space-constrained builds. It offers a valid fit for 1U cases but lacks the versatility for modern systems.
Key specs explained for this cooler
Socket Compatibility: LGA1155, Socket 1156
This listing confirms support for Intel LGA1155 and LGA1156 sockets. You should verify your motherboard uses one of these specific layouts before purchasing. This cooler is not compatible with modern LGA1700 or AM5 platforms. It targets older Xeon and Core i7 processors from the second generation. Check your CPU manual to ensure the pin layout matches this requirement for proper mounting.
Heat Sink Material: Aluminum with Skiving Fins
The heatsink uses aluminum, a lightweight metal that conducts heat well but is softer than copper. Skiving fins are cut from a single block of metal rather than extruded. This method creates thin, dense fins that increase surface area for cooling. Aluminum keeps the overall weight low, which is crucial for small server chassis where heavy components can stress mounting points.
Dimensions: 95.0 x 95.0 x 26.5 mm
These measurements define the physical footprint and height of the unit. The 26.5 millimeter height is the critical factor, as it fits within the strict 1U form factor for rackmount servers. The 95 by 95 millimeter base matches standard mounting holes. You must ensure your case has at least 26.5 millimeters of clearance above the CPU socket to avoid interference with other components.
Weight: 300.0g
The unit weighs 300 grams, which is relatively light for a heatsink. This low mass reduces stress on the motherboard socket and mounting brackets. It is easier to install in tight server racks where space is limited. Compare this to larger desktop coolers that can weigh over a kilogram. The lighter weight makes handling simpler during installation in confined spaces.
Design and build details
The heatsink core is constructed from aluminum with skived fins. This manufacturing method creates thin, continuous fin layers that improve thermal contact with the heat pipes. The material choice prioritizes weight reduction and cost efficiency over the higher thermal conductivity of copper. You should expect standard aluminum performance characteristics in this form factor.
According to the listing, the physical dimensions are 95.0 by 95.0 by 26.5 millimeters. This specific height is critical for 1U server chassis, where vertical clearance is extremely limited. The base footprint matches standard mounting patterns for LGA1155 and LGA1156 sockets. The unit weighs 300.0 grams, or approximately 11 ounces. This mass is typical for compact aluminum blocks and ensures stable mounting pressure without excessive strain on the motherboard.
The RoHS compliant finish indicates the absence of restricted hazardous substances in the manufacturing process. This is a standard requirement for commercial and enterprise hardware. The design lacks active control features or RGB lighting, focusing solely on passive thermal dissipation. You will need to connect a separate fan to the header, as this is a heatsink-only component. The layout is optimized for airflow through narrow server racks rather than open desktop cases. Ensure your chassis supports the 1U height constraint before installation.
Installation and Daily Operation
Setting up this Dynatron K1 requires careful attention to your motherboard socket layout. The listing specifies compatibility with LGA1155 and Socket 1156. You must verify that your server or desktop board uses one of these specific Intel interfaces. This cooler is not designed for modern platforms like LGA1700 or AM5. The physical dimensions are 95 by 95 by 26.5 millimeters. This compact footprint ensures it fits within strict 1U chassis constraints. The unit weighs 300 grams, or 11 ounces. This moderate weight is manageable for standard server racks but requires secure mounting to prevent vibration during operation.
Daily use involves running workloads compatible with the supported processors. The feature list confirms support for Intel Core i3, i5, and i7 models from the second generation, as well as the Xeon 3400 series. You should ensure your CPU falls within these specific model families for proper thermal management. The aluminum construction with skived fins provides efficient heat dissipation for these specific chips. However, the small height limits airflow volume. You will need adequate case fans to push air through the dense fin stack. This setup is ideal for low-power server environments or older desktop systems where space is at a premium. It is not suitable for high-end gaming rigs or heavy rendering tasks on modern hardware. The RoHS compliance indicates the materials meet environmental standards, which is relevant for professional server deployments.
Before You Buy This Cooler
Before you buy this Dynatron K1, verify your motherboard socket is strictly LGA1155 or LGA1156. This cooler does not support modern platforms like LGA1700 or AM5. You will need to check your chassis clearance, as the 26.5 millimeter height fits only 1U server racks or specific low-profile desktop cases. The aluminum construction requires you to apply high-quality thermal paste for optimal heat transfer. Skived fins perform best when paired with adequate airflow. Since this unit lacks fan mounting holes in the listing, you may need to source compatible fans separately or ensure your case provides direct airflow. This option suits users with older Xeon or Core i7 processors who need a compact solution. It sits alongside other air coolers as a niche choice for space-constrained builds rather than high-end gaming rigs. Regular dust cleaning is essential to maintain its thermal performance over time.
Check before you buy
- Verify motherboard socket is LGA1155 or LGA1156.
- Check chassis height clearance for 26.5mm limit.
- Ensure adequate case airflow for skived fins.
- Source compatible fans if not included.
