Quad-core LGA 1151 server processor

The Intel Core i5-6600 is a new quad-core server processor built for the LGA 1151 socket. It runs at a 3.30 GHz base frequency and can reach a 3.90 GHz maximum turbo frequency. The chip includes 6MB of L3 cache and operates within a 65W thermal design power envelope.

Suits single-threaded workloads.

This processor suits workloads that benefit from higher single-core speeds such as legacy application hosting, light web serving or database instances with limited concurrent connections. Builders needing more than four threads for virtualisation density, heavy compilation or parallel rendering should look at a different component.

65W TDP determines cooler and power budget

The 65W thermal design power is the key specification for system integration. It dictates the cooling solution capacity required and the power budget available for the rest of the server build. The processor is sold without a cooling device so a compatible heatsink must be sourced separately.

Questions about this item

What socket and cooler clearance does the 65W Core i5-6600 require?

The processor uses an LGA 1151 socket and ships without a cooling device, so you must supply a compatible cooler that fits your chassis and the 65W thermal envelope.

Which installation step is most often missed when seating this FCLGA1151 CPU?

Builders frequently forget to engage the load-plate lever fully after placing the chip in the socket; the lever must click shut to make reliable contact.

What component will need replacement first on a continuously running SR2L5 unit?

The aftermarket cooler's fan or thermal paste will degrade before the processor itself, so plan to refresh paste and verify fan operation every few years.
