Disclaimer: Displayed parts and accessories may not be included in the actual product package.

Description

Redefining cooling performance for space restricted environments, GeminII M4 is engineered to maximize cooling with its minimal CPU contact gaps and four extremely efficient direct contact heat pipes that provide excellent heat dissipation. Standing at a mere 59mm / 2.3in tall, it is uniquely suited to thrive in the small spaces afforded to CPU coolers in HTPCs and other slim systems.

A unique heat pipe layout is utilized that orients the heat pipes to direct the flow of heat more efficiently to the aluminum fins where the heat is exhausted. Much like the GeminII S524, GeminII M4 features an airflow design that is 90 degree rotated to avoid heat radiating from the motherboard. In turn, this orientation simultaneously provides a steady airflow to motherboard chipsets surrounding the CPU socket.

  • Super low profile cooler (59mm / 2.3in height) with 4 direct contact heat pipes.
  • A base engineered to minimize CPU contact gaps provides excellent heat conduction.
  • Suitable for limited space applications (e.g. HTPC or slim systems).
  • Newly developed thin fan profile delivers uncompromised cooling performance in a compact package.
  • Unique heat pipe layout combines two very effective cooling methods to increase cooling efficiency while maintaining a low profile heat sink.

      "Bottom line, the low profile Coolermaster Gemin II M4 heatsink offers good thermal performance at full fan speed in sub-75mm tall PC enclosures. The heatsink is generally very quiet, but operating this cooler at its slowest fan speed is best reserved for sub-95W TDP computer processors."

      "Overall performance is about what we had expected.  Going into this review we knew the M4 wasn't a cooler centered at overclocking but rather to provide an efficient low profile cooling solution.  The Gemin II M4 delivers on that by using a four heatpipe core contact design that measures in with a total height of 59mm, including the fan."

      "The Cooler Master GeminII M4 is a great little cooler if you are working with space restrictions. If you are working with a mATX or ITX system in a small form factor enclosure this cooler is definitely worth a look. It will fare way better than that of the stock cooler when it comes to cooling performance and remain just as quiet. And these are two of the main factors of a CPU cooler when working in these tight confinements. "

      "In the average HTPC/slim build, the GeminII M4 is going to provide excellent cooling in a small form factor at a low price. Cooler Master then managed to throw in incredibly easy mounting and near silent operation. Really, what more could you possibly want for this type of application? It is just very important that the GeminII M4 is used in the proper application and not asked to cool the higher power CPUs. For a tight space with a CPU under 100W, the GeminII M4 is a rock solid choice."
