Manufacturer description

The ID-COOLING IS-55 Black is a 57mm low-profile CPU cooler built for Mini-ITX, HTPC and small form factor cases where a tower cooler won't fit. Five heatpipes carry heat from the CPU into the fin stack, and a slim 120x120x15mm PWM fan sits on top. The fan moves up to 54.6 CFM, and its noise ranges from 13.8 dB(A) at low speed to 31.2 dB(A) at full speed. Because it's a PWM fan, your motherboard adjusts the speed automatically, so it stays near the quiet end at idle and speeds up only under load. ID-COOLING says the compact design leaves room for memory, even on crowded Mini-ITX boards where…

Frequently Asked Questions

How tall is the ID-COOLING IS-55 and will it fit my case?

The IS-55 is 57mm tall in total, including the fan. Check your case's listed maximum CPU cooler height. If the case allows 57mm or more, the cooler fits.

Does the ID-COOLING IS-55 work with AM5 and LGA 1851?

Yes. The listed compatibility includes AMD AM5 and AM4, plus Intel LGA 1851, 1700, 1200, 1151, 1150, 1155 and 1156.

How loud is the IS-55 fan?

The 120x120x15mm PWM fan is rated at 13.8 to 31.2 dB(A). PWM control lets your motherboard keep it near the low end at idle and speed it up under load.

Will the IS-55 block my RAM on a Mini-ITX motherboard?
