Cooler Master, like many companies that cater to PC enthusiasts, tends to focus on large, high-end liquid and air coolers. But because compact systems are a consistent niche, the company occasionally offers up low profile designs to fit those specific needs. Enter the G200P, a hyper-compact cooler, to accommodate airflow for the smallest of small systems.
With a height of just 39.4mm, the Cooler Master G200P is powered by a single 92mm RGB fan that absolutely shreds air at high RPMs across the cooling fins of its tiny, dual-heatpipe cooler. And while this all sounds like a perfect combination of style and small-system performance, the G200P offers more in terms of style than it does in cooling performance.

The tiny G200P ships with a normal assortment of mounting hardware, including an AMD+Intel universal backplate and plated hardware to fit most desktop processor sockets for each aforementioned CPU manufacturer. An RGB control module provides out-of-the-box color control for motherboards devoid of 4-pin, 12v RGB support-- which is NOT compatible with 3-pin, 5v aRGB (just to clarify). Alongside the usual array of mounting hardware, a small tube of MasterGel Pro thermal compound comes standard.
Cooler Master covers the G200P with a 2 year warranty.
A pair of U-shaped heatpipes run down the span of the cooling fin heatsink and wrap under the base of the G200P, where they tuck up under the cooler and into the solid coldplate. The fan shroud wraps around the sides of the 95mm X 92mm cooler and provides threaded machine screw mounts for the 92mm fan.
The 92mm fan is 4-pin PWM-managed spinner and makes use of 4-pin, 12v RGB (again, not compatible with 3-pin, 5v aRGB). The frosted crystal 9-blade design allows for strong light diffusion without excessive bright spots, and fan speed is rated up to 2600 RPM.
The underside of the cooler houses the nickel-plated coldplate, which is integrated with the side channels which wrap up and around the cooling fins and provide mounting for the 92mm cooling fan. The downdraft design flows through the majority of the cooler and frame, allowing air to blow around and through the heatpipes and move heat down and away from the cooler.
The cold plate is milled flat, without any visible light peeking out between the base of the cooler and a steel straightedge.
Once the cooler is removed after mounting, we observed a uniform thermal paste spread across the face of the CPU integrated heat spreader. Incremental tensioning between the mounting screws helps maintain consistent displacement of compound. Note, though, that tightening one side fully and then the other can result in offset paste coverage.
While it boasts a relatively small footprint, the G200P still fits snugly onto our mITX motherboard, with just millimeters of clearance between the sides of our Super Talent DDR4-3000 memory DIMMs and the side of the heatsink itself. Even with this close fit, the cooler should not have any memory interference issues due to its design.
The pair of primary tension screws can be seen in the middle of the cooler, as it sits astride the mounting brackets and standoffs below. Each U-shaped heatpipe unfurls outward into the cooling fins to maximize contact.
With the fan mounted, the Cooler Master G200P brightens up the dark recesses in our small system, once power is applied to the RGB fan.
For our CPU cooling tests, we use the same hardware, overclock and configuration for every test to minimize environment variables in testing. This allows for all results across all coolers tested on the platform to be viable as side-by-side examination for direct compare/contrast.

Comparisons are based on data collected from testing performed on our Intel i3-8350K system.
Prime95 v29.4b8 (no AVX) is used for two-hour intervals, one managing fans at 50% PWM and the other at 100% PWM with RPM measurements being taken every 3 seconds and averaged across the duration of each 2-hour capture. Omitting AVX instruction sets allows for accurate, 100% loads at chosen clock speeds, while allowing AVX instructions would provide higher, albeit, unrealistic synthetic CPU loads and excessive heat production, less indicative of real-world use.
HWInfo64 is used for real-time core temperature readout, thermal throttling alerts, motherboard power consumption, CPU speed and logging of data, while a CrystalFontz CFA-633-TMI-KU is used to monitor and later average both ambient room (2 probes) and motherboard voltage regulator heatsink (2 probes).
The Cooler Master G200P doesn’t exactly lead the pack in terms of cooling potential. Rather, it lags behind the majority of other small heatpipe coolers, including Intel OEM cooling solutions.
Most of our small cooling solutions utilize smaller diameter fans with higher RPM ratings, which tends to push some of our graphs further to the right than we typically see.
As expected, higher fan speeds typically result in elevated decibel levels across several of the small coolers on the list. Most notably, the pair of Intel OEM coolers top out with some rather high noise values, while the Scythe Choten TUF and its 120mm fan are almost whisper-quiet compared to the others tested here.
Our acoustic efficiency chart compares how well different coolers are able to dissipate thermal energy, while also evaluating the noise levels they each can effectively do this work. Coolers which struggle to perform or exhibit higher decibel values, or both, will see lower values.
Performance value compares the data from our acoustic efficiency chart and then evaluates unit price in the equation. The Cooler Master G200P sees poor thermal load results, which tend to hold it back, while also being priced at $45, giving it a low performance value score. Meanwhile, the Intel E97379-003 only performs slightly better than the Cooler Master G200P and produces a larger registered sound level, it is priced at only $10, giving it a considerable advantage for raw value alone.
The Intel BXTS15A really shines as a performance value candidate, due to its relatively good thermal scores but also while being fiscally sound.
Thermal imaging with our FLIR ONE Pro camera shows a significant difference between 100% and 50% PWMm as well as elevated localized regions of heat soak around the cooler and adjacent motherboard components. With such a small footprint, smaller coolers like the Cooler Master G200P rely heavily on higher fan speeds to dissipate thermal loads with greater efficiency.
Overall, the Cooler Master G200P is a very handsome small-form-factor cooler with a very bright RGB fan, which shouldn’t cause any installation issues around memory compatibility, making it highly versatile. However, even in smaller system builds, the G200P doesn’t handle sustained CPU loads and temperatures very well. So unless your small system build is absolutely focused on themed RGB lighting, there are other options which can provide better cooling performance.
