With dimensions of 3.9 x 3.3 x 5.5 inches, it fits neatly into mini-ITX cases. This listing provides a clear look at the specifications for Intel sockets 1150, 1155, 1156, and 1200, helping you decide if it meets your thermal requirements.
What stands out
- Four 6mm copper heat pipes with direct-touch base technology for efficient heat transfer.
- 92mm PWM fan with a maximum speed of 2800RPM and airflow of 46.5CFM.
- Compact dimensions of 3.9 inches wide and 3.3 inches high for small cases.
- Compatible with Intel LGA 1150, 1155, 1156, and 1200 sockets.
Who it fits
Good fit for
You should consider this cooler if you are building a mini-ITX system with limited clearance. The small footprint allows it to fit in cases where larger coolers will not. It suits users with Intel processors on sockets 1150, 1155, 1156, or 1200 who need reliable passive cooling without bulky hardware. The direct-touch heat pipes help manage heat from mid-range CPUs efficiently. If space is your primary constraint, this spec sheet suggests it is a viable option for your build.
Who should skip it
You should look elsewhere if you have a high-end CPU that generates significant heat. The 92mm fan and aluminum fins may struggle with heavy loads compared to larger 120mm or 140mm coolers. If you need maximum airflow, the 46.5CFM limit might not be enough for sustained performance. Additionally, this model only supports older Intel sockets. If you use a newer platform like LGA 1700 or AMD AM4, this cooler is not compatible with your motherboard.
Verdict: This cooler is a practical choice for space-constrained mini-ITX builds using compatible Intel sockets. It offers sufficient cooling for moderate loads but is not ideal for high-performance gaming rigs.
Key Specs Explained For EVGA
92 x 92 x 25mm Fan
This small form factor allows the cooler to fit into compact cases where larger units will not. You benefit from a lower profile that avoids interference with RAM sticks or side panels. When shopping, compare this size to standard 120mm fans to understand the space savings and potential noise trade-offs in tight builds.
2800RPM Max Fan Speed
This rating indicates the highest rotational speed the fan can reach. Higher speeds move more air but generate more noise. You should check if your motherboard supports PWM control to adjust this speed dynamically. When comparing air coolers, this max speed helps you gauge the peak cooling potential and acoustic level.
46.5CFM Max Airflow
This value measures the volume of air the fan moves per minute. Higher CFM generally means better heat removal from the CPU. You use this number to compare airflow efficiency against other coolers in the same price range. It helps you decide if this fan provides enough cooling for your specific processor workload.
4x 6mm Copper Heat Pipes
These pipes transfer heat from the CPU base to the aluminum fins. The 6mm diameter offers a balance of thermal mass and weight. You benefit from direct contact technology which improves initial heat transfer. When shopping, compare pipe count and diameter to assess how quickly the cooler can spread heat away from the processor.
3.9 x 3.3 x 5.5 inches
These dimensions define the physical footprint of the heatsink and fan assembly. You must verify these measurements against your case specifications to ensure proper clearance. This compact size is ideal for mini-ITX builds. When comparing products, use these exact measurements to avoid fitment issues in small chassis designs.
Design and Build Details
According to the listing, the heatsink combines aluminum fins with four 6mm copper heat pipes. This construction uses direct-touch base technology to improve thermal transfer. The aluminum fins provide surface area for heat dissipation, while the copper pipes conduct heat away from the CPU quickly. You get a balanced approach to cooling without relying solely on heavy copper mass.
The unit measures 3.9 inches wide, 3.3 inches high, and 5.5 inches long. It weighs 1.4 pounds. These dimensions define its compact footprint. The low height ensures it clears most RAM modules and fits into small cases. The width and length keep it contained within the processor socket area. This layout prevents interference with surrounding components in tight builds.
Control comes from a 92 x 92 x 25mm PWM fan. The fan speed ranges from 800 to 2800RPM. You can adjust the speed via motherboard settings. The maximum airflow reaches 46.5CFM. This range allows you to balance noise and cooling performance. The sleeve bearing supports the fan rotation. The build focuses on fitting into mITX systems where space is limited. You get a straightforward design that prioritizes compatibility and size over aesthetic extras.
Installation and Daily Operation
Setup begins with verifying socket compatibility. This cooler supports Intel LGA 1150, 1155, 1156, and 1200 sockets. You must ensure your motherboard matches one of these specific connections before mounting. The physical dimensions are critical for small form factor builds. The unit measures 3.9 inches in width, 3.3 inches in height, and 5.5 inches in length. Its compact footprint allows it to fit into tight cases where larger coolers would fail. You should check clearance around the RAM slots and side panels to avoid interference.
Once installed, the 92 x 92 x 25mm fan manages airflow. It operates using PWM fan control, allowing your motherboard to adjust speed based on thermal needs. The fan speed ranges from 800 to 2800 RPM. At maximum speed, it moves 46.5 CFM of air. This variable speed profile lets you balance cooling performance with acoustic output during daily use. The direct-touch base technology connects the four 6mm copper heat pipes directly to the CPU surface. This design aims to improve heat transfer efficiency from the processor to the aluminum fins.
The total weight is 1.4 pounds. This mass is manageable for standard mounting hardware. You do not need specialized tools beyond what is typically included. The combination of PWM control and compact size makes this unit suitable for users prioritizing space efficiency over extreme thermal headroom.
Before You Buy This Cooler
You should verify your case clearance before purchasing. The cooler measures 3.9 inches wide, 3.3 inches high, and 5.5 inches long. These dimensions ensure it fits in small form factor builds without blocking RAM or side panels. Check your motherboard socket. This unit supports Intel LGA 1150, 1155, 1156, and 1200. It does not list AMD support, so confirm your platform matches. You need a motherboard header for PWM fan control. The fan operates between 800 and 2800RPM. Dust accumulation on the aluminum fins can reduce performance over time. Clean the fins gently with compressed air every few months. This cooler is a specialized option for compact cases. It sits alongside larger air coolers that offer higher airflow but require more space. Choose this if space is your primary constraint rather than raw cooling headroom.
Check before you buy
- Verify your case dimensions allow 3.3 inch height clearance.
- Confirm your motherboard uses Intel LGA 1150, 1155, 1156, or 1200.
- Ensure your motherboard has a 4-pin PWM fan header.
