Who it fits

Key specs explained

Socket Compatibility: LGA 775

This cooler fits only Socket 775 motherboards. You must verify your board supports this specific socket before buying. It will not work on modern LGA 1700 or AM5 platforms. If you have an older system, this matches. For new builds, check your CPU socket type first. This ensures physical fitment and mounting bracket compatibility without guesswork.

Fan Speed: 3600 RPM

The fan spins at 3600 rotations per minute. This speed moves more air for better cooling. Higher RPM usually means more noise. You get strong airflow for heat dissipation. Compare this to lower RPM fans for quieter operation. If you need quiet, look for lower speeds. This spec helps you balance cooling performance against acoustic comfort in your case.

Construction: Copper core, aluminum fins

The base uses copper for fast heat transfer from the CPU. The fins use aluminum for lightweight heat dissipation. This mix balances efficiency and weight. Copper conducts heat better than aluminum alone. You get effective cooling without excessive mass. When shopping, compare all-copper vs. hybrid designs. This hybrid approach offers good thermal performance at a reasonable weight for standard cases.

Bearing Type: Sleeve bearing

The fan uses a sleeve bearing mechanism. This design is common and cost-effective. It provides decent reliability for standard use. Sleeve bearings may wear out faster than fluid dynamic bearings over time. You should monitor noise levels as the cooler ages. Compare this to higher-end bearings if you plan to keep the cooler for many years. It suits users who replace hardware periodically.

Design and Build Details

The heatsink combines a copper core with aluminum fins. Copper conducts heat quickly from the CPU. Aluminum fins spread that heat into the air. This hybrid design balances efficiency and cost. You get effective thermal transfer without a full copper block. The listing confirms this material mix for the Ultra P4 model.

Physical dimensions are specific for your case. The unit measures 9.7 inches in length, 3.7 inches in width, and 7.1 inches in height. It weighs one pound. These measurements matter for clearance. You must check your case side-panel space. Tall cases accommodate the 7.1-inch height. Narrow cases might block the side panel. RAM clearance can also be tight. The 3.7-inch width fits standard tower slots. The 9.7-inch length extends over the socket area. Verify your motherboard layout before installation.

The fan mounts directly to the heatsink. It operates at 3600 RPM with PWM control. PWM allows the motherboard to adjust speed. This helps balance noise and cooling. The bearing type is sleeve. Sleeve bearings are common in this price range. They require less maintenance than ball bearings but may not last as long. The listing notes these specs. You should monitor fan noise if you run the system at full speed. The build is straightforward. It lacks complex features. It focuses on basic cooling for Socket 775 systems.

Setup And Daily Use Guide

Installing this cooler requires matching the LGA 775 socket. You must verify your motherboard supports this specific platform before beginning. The unit weighs one pound and measures 3.7 by 9.7 by 7.1 inches. This footprint fits most standard cases, but you should check clearance against nearby RAM slots or chassis walls. The mounting process involves securing the heatsink to the board and connecting the fan cable. The fan supports PWM speed control, allowing your motherboard to adjust rotation automatically based on thermal load. The sleeve bearing design means you will hear airflow noise, especially at the maximum 3600 RPM speed. This is typical for this bearing type and budget segment. Daily operation relies on the copper core to pull heat from the CPU die. The aluminum fins then dissipate that heat into the case airflow. You should ensure your case has adequate intake and exhaust fans to support this passive dissipation method. The hybrid construction balances thermal performance with weight. It is not designed for extreme overclocking scenarios. It suits users with stock processors who need reliable, quiet-enough cooling for general computing tasks. The PWM feature helps maintain lower noise levels during idle periods. You do not need additional software to manage speeds, as the motherboard handles the control. This simplicity is a key advantage for basic builds.

Before You Buy This Cooler

This cooler targets older LGA 775 systems. You must confirm your motherboard uses this specific socket. It will not fit modern platforms like LGA 1700 or AM5. The unit weighs one pound and measures 3.7 by 9.7 by 7.1 inches. Ensure your case has enough clearance for this height. The sleeve bearing fan runs at 3600 RPM. You should check dust buildup regularly. Clean the aluminum fins with compressed air to maintain airflow. The copper core helps transfer heat efficiently. This design balances cost and performance. It suits budget builds or legacy machines. If you need silent operation, consider other options with lower RPM fans. This model focuses on basic cooling needs. Pair it with good thermal paste for best results. Verify fan headers on your board support PWM control. This ensures proper speed adjustment. Keep cables tidy to avoid obstructing airflow. This cooler fits well alongside other air cooling solutions for older hardware. It provides reliable performance without extra features.

Check before you buy

• Verify your motherboard supports LGA 775 socket.
• Check case height clearance for 7.1 inch cooler.
• Confirm PWM fan header availability on board.
• Plan regular dust cleaning for sleeve bearing.
