Manufacturer description
The Intel E97379-003 is the factory heatsink and fan that shipped with LGA115x desktop processors, which makes it the direct replacement when a Core i3, i5, or i7 build is missing its cooler or the original fan has finally seized. It uses the stock Intel mounting for LGA115x boards, so you are not sourcing an aftermarket bracket kit or backplate to get a machine running again. The 4-pin fan connector plugs into a standard CPU fan header and hands speed control back to the motherboard, so the fan ramps with load instead of running flat out. At 11.94 x 10.41 x 7.11 cm and 181 grams, its 7.11…

Frequently Asked Questions
Which sockets and CPUs does the E97379-003 fit?
It is specified for Intel LGA115x desktop sockets and Core i3, i5, and i7 processors. Confirm your motherboard socket is in the 115x family before ordering, since it will not mount on newer Intel sockets or on AMD boards.
Does it come with thermal paste?
The listing does not state that thermal compound is pre-applied, so plan on having a tube of paste on hand. Check the product listing before ordering if you need that confirmed.
Will the fan speed adjust automatically, or does it run at full speed?
It uses a 4-pin fan connector, so a motherboard CPU fan header can control it by temperature and load rather than running it at a fixed RPM.
Will this fit inside a small or slim desktop case?
Its dimensions are 11.94 x 10.41 x 7.11 cm at 181 grams. Measure your case CPU cooler clearance against the 7.11 cm height before buying, especially in low-profile OEM chassis.
Is it good enough for an overclocked CPU?
No. This is the factory cooler for stock-clocked i3, i5, and i7 chips. Sustained overclocks call for a tower or liquid cooler.
