Back in 2009, we did a couple of roundups of smallish CPU heatsinks which consisted of some petite stock unit replacements and performance coolers of varying sizes. The 86 mm tall Cooler Master GeminII S was one of the reviewed models, but today it wouldn't even qualify as a compact heatsink. The proliferation of mini-ITX motherboards and cases over the past two years has fueled the need for smaller coolers, closer to 60 mm or less in height.

The Cooler Master GeminII M4.
|
The latest GeminII, the M4, is more contemporary with today's standards. It bears more than a passing resemblance to one of the best small heatsinks on the market today, the Scythe Big Shuriken 2. Its dimensions are almost identical, though the M4 is substantially lighter, and its slim 120 mm fan is a bit thicker. On paper, the other big difference is the use of four direct-touch heatpipes; the Big Shuriken 2 has five heatpipes and a copper base plate.

Package contents.
|
The box is no larger than it needs to be. The heatsink comes packed in a protective foam layer along with the accessories. The mounting hardware includes a backplate despite the M4's low mass, and LGA2011 clips are provided right out of the box. There's also an instruction sheet, a tube of thermal compound and a nut-driver.

Feature & Brief
|
Our Comment
|
| Super low profile cooler (59mm / 2.3in height) with 4 direct contact heat pipes. |
For a smaller heatsink, four heatpipes seems like a lot but they're quite short. |
| A base engineered to minimize CPU contact gaps provides excellent heat conduction. |
Okay. |
| Suitable for limited space applications (e.g. HTPC or slim systems). |
That's why we're here. |
| Newly developed thin fan profile delivers uncompromised cooling performance in a compact package. |
A thinner than normal fan is utilized to keep the size down. |
| Unique heat pipe layout combines two very effective cooling methods to increase cooling efficiency while maintaining a low profile heat sink. |
Direct-touch heatpipes contact the processor heatspreader directly, making a separate base plate unnecessary. |
