"The Igloo 5710 Plus Silent ships with a quiet 1300RPM 100mm fan and installs out of the box thanks to a pre-applied patch of shinetsu thermal compound. A nice touch given its suitability for generic office PCs where non-experts may be tasked with the heatsink's installation. It's economical price should help make the heatsink attractive to office type PC applications. Given its relatively compact height of 139mm, the Igloo 5710 Plus Silent will fit in most mid-tower and compact PC cases easily enough."
