Cooler Master recently at CES launched a big range of air CPU coolers under the MASTERAIR product line. This new product line features all new design cooler with silent fans and top of all RGB lighting, supporting all type of PC build needs.

One of the air cooler that really caught out a huge attention with its unique low profile UFO like design was the Cooler Master MASTERAIR G100M CPU cooler. Equipped with a ground breaking heat column technology, low profile and top down air flow design with 92mm of PWM fan with RGB lighting and more.

Now let’s see what more the MASTERAIR G100M CPU cooler have for us.

Features

BREAK-THROUGH IN HEAT TRANSFER
The MasterAir G100M Heat column technology is a two-phase heat transfer involves the liquid-vapor phase change (boiling/evaporation and condensation) of a working fluid. The fluid is transferred by the copper powder filled inside the column creating an anti-gravity heat transfer.

7X LARGER DIAMETER THAN HEATPIPES
Super quick heat transfer is made possible with Heat Column at a massive Ø41.2, the equivalent of 7X the size of traditional heatpipes. The unification of heatpipes and base into one unit captures and efficiently transfers the heat from CPU like never seen before.

LOW PROFILE FOR MINI-ITX BUILDS
The low profile G100M stands at 74.5mm, a great fit for slim PC cases, including mini-ITX cases. Even at these small dimensions, the heatsink has cooling capacity of 130W TDP.

RGB LED ILLUMINATION (CONTROLLER INCLUDED)
A wired RGB LED controller is included with the G100M to personalize the RGB lighting anytime you want (no software needed). Switch it up depending on your mood, the possibilities are not limitless.

TOP DOWN AIR FLOW PERFORMANCE
A high performance 92mm PWM fan with a range of 600 ~ 2400 RPM, cools not only the CPU, but all surrounding components inside the case for exceptional thermal results.

QUICK AND EASY INSTALLATION
Tool-free mounting kit makes installation a breeze. Universal retention brackets are included, with full compatibility for: Intel® LGA 2066 / 2011-v3 / 2011 / 1151 / 1150 / 1155 / 1156 / 1366 / 775 AMD® AM4 / AM3+ / AM3 / AM2+ / AM2 / FM2+ / FM2 / FM1

Installation

Being a low profile cooler, the MasterAir G100M is not suitable for all of the motherboards out there.

I tried two different high end motherboards (ASUS X99 deluxe and Gigabyte Z170X Gaming G1) and failed to install the cooler on both boards with the installation kit provided with the cooler.

Trying ASUS X99 deluxe

Due to space between the VRM heatsink and the memory slot, one cannot reach the threaded nut to tight it over the standoffs to secure the cooler. The provided tool don’t reach nuts, also tried long pliers but failed to install the cooler.

Trying Gigabyte Z170X Gaming G1

Same story here, due to big VRM 90 degree heatsink there was not even space left between the heatsink and Cooler to push the threaded nut inside over the standoffs.

Cooler installation can be done with the provided kit but was very difficult and requires lot of skill with patience. Not an easy user friendly experience at all.

Then I dropped the idea of using the provided installation kit. I used four 4mm x 35mm fan screws and tighten them onto the cooler, then passed the cooler with screws through the motherboard CPU mounting holes. Used the provided back plate and threaded nuts to secure the cooler in place. And this all was easily done without pulling the motherboard out of the case. Where earlier motherboard has to be out of the cabinet.

This type of back screw mounting technique is used in mostly all low-profile coolers, due to nature of the formfactor.

I don’t know why Cooler Master dropped the known and easy technique of installation for this type of product with MasterAir G100M cooler.

For testing thermal capability we manually overclocked delidded Intel Core i7 7700K CPU upto 4.8GHz and stressed the CPU using AIDA64 for 10 minutes. To average out we took three readings with 15 minutes of system idle time in between every reading. We compared MASTERAIR G100M CPU cooler with few of known AIOs, Air coolers and a custom LC solution.

Ambient Temperature 24C

At Idle the CPU cooler was very silent and at full load cooler do product little fan noise in open test bench, but when installed inside a closed case the noise of the fan was not that noticeable.

Pros

  • Nice design and looks
  • RGB Fans
  • Comes with RGB controller and support major motherboard RGB utility
  • 2 years warranty
  • Nice Price

Cons

  • Serious installation issue with motherboards having big VRM heatsinks
  • Compatibility problem with high height memory modules
  • Cannot install with motherboard inside the case.

Conclusion

Cooler Master MASTERAIR G100M CPU cooler have a very attractive design and with RGB lighting this cooler looks very good and attracted lot of attention in media. Performance wise the cooler is nice for its low-profile design.

I had major difficulty in installing this cooler on motherboards having big VRM heatsinks, cooler installation works good with motherboards having small or No VRM heatsinks, than after one must pull the motherboard out of the case to install it. Second, I feel disappointed that Cooler Master could have used the back side mounting technique used in mostly all low-profile coolers with this cooler too and could make product more user friendly.

Finally at a price tag of Rs.3.5k(approx.), the Cooler Master MASTERAIR G100M CPU is a great looking cooler with nice performance, but one can face some issue with installation of this cooler if motherboard is having big VRM heatsinks.
