Cooler Master RR-GMM4-16PK-R2 overview

  • 1Description

Coolermaster's GeminII M4 CPU Cooler is engineered to maximize cooling in small form factor systems. In combination with its four heat pipes and a unique heat pipe design, it directs the flow of heat more efficiently to the aluminum fins where the heat is dissipated by the slim 120mm fan. The GeminII M4 features a 90 degree airflow design rotated to avoid heat radiating from the motherboard. In turn, this orientation simultaneously provides a steady airflow to motherboard chipsets surrounding the CPU socket.

Low profile cooler (2.3"/59 mm tall) with 4 direct contact heat pipes
Engineered base to minimize gaps and conduct heat more efficiently
Ideal for limited space applications (e.g. HTPC or slim systems)
Thin profile fan delivers cooling performance in a compact package
Unique heat pipe layout combines two cooling methods to increase cooling efficiency

    Cooler Master RR-GMM4-16PK-R2 reviews

    GeminII M4 CPU Cooler is rated 3.5 out of 5 by 2.
    Rated 4 out of 5 by from A solid low-profile cooler with finicky mounting hardware. This cooler works very well even on a Core i7-4790K. Maximum temperature under IBT was 69C, although keep in mind this CPU has been delidded. The mounting hardware is a bit fussy because CM uses the same backplate for all CPUs, AMD and Intel. If you think it's being really hard to install, you're probably doing it wrong. The instructions aren't very good either. I also wasn't blown away by the flimsy fan, but it is pretty quiet. -0.5 stars for the instructions and -0.5 stars for the fan. 4/5 ain't bad.

    Rated 3 out of 5 by from Not socket AM4 compatible Originally this cooler was identified as with AM4 support. However, that has been changed, and as of 8-25-17 Cooler Master's website does not indicate an AM4 bracket will ever be forthcoming. Out of the package, this cooler will NOT fit the AM4 socket holes in the MOBO. Not sure how effectively it would work in a slim HTPC build, as I was never able to mount it.
