Intel E29477-002 Socket 1366 Copper Core Heat Sink & 4in Fan

In this review of the Intel E29477-002 heat sink and fan, the bottom line is simple: this is a straightforward, reliable replacement cooler for Socket 1366 systems, best suited to users who need a direct, OEM-style swap for older Core i7 processors. The unit pairs an aluminum fin stack with a copper core and a compact 4in fan on a 4-pin connector, delivering effective cooling for Core i7-920 and similar Socket 1366 CPUs up to 3.06 GHz. It is not flashy, but it does what matters: it cools, fits the platform, and comes with standard regulatory approvals.

Key Features

• Copper core with aluminum fins: provides focused heat transfer from the CPU die to the fin stack for stable temperatures under load.
• 4in DC fan: offers active airflow at DC 12V, 0.30A to help dissipate heat generated by Socket 1366 processors.
• Socket 1366 compatibility: designed specifically to support Intel Core i7 Socket 1366 processors up to 3.06 GHz for confident direct replacement.
• 4-pin connector: the PWM-ready connector and roughly 10in cable length allow motherboard fan control and flexible routing inside standard towers.
• Regulatory approvals: UL and CE approvals indicate the fan and assembly meet basic safety and compliance expectations.

Who It's For

This cooler is aimed at owners of older Socket 1366 systems who want an OEM-style replacement that restores original cooling performance without modifying mounting hardware or paying for a high-end aftermarket solution. Builders maintaining legacy workstations, hobbyists refurbishing servers, and those replacing a failed stock fan will find its fit and function convenient.

It is less appropriate for enthusiasts seeking the quietest, highest-performance aftermarket coolers or those building modern platforms; users wanting ultra-low noise or higher thermal headroom should look at contemporary coolers designed for current sockets.

Pros & Cons

Pros

• Direct fit for Socket 1366 makes installation straightforward and reliable.
• Copper core improves heat transfer compared with all-aluminum designs.
• Functionality and quality are reported positively by customers as a faithful replacement.
• 4-pin connector enables motherboard fan speed control for temperature-based adjustments.

Cons

• Noise level is mixed in customer feedback, so it may be louder than some modern low-noise options.
• Not suitable for higher-TDP modern CPUs or users needing advanced cooling performance beyond stock needs.
