Deepcool GAMMAXX 300 (DP-MCH3-GMX300)
 | Outdated Product Affordable universal CPU cooling system (processor cooler) with a tower form factor designed for heat dissipation from Mainstream/Performance class processors manufactured by Intel and AMD with a thermal output up to 130W. It is positioned as one of the available products in the mid-price category. It will be of interest to users who are not satisfied with the performance and noise level of stock CPU cooling systems. The basis of the Deepcool GAMMAXX 300 processor cooler is a system of three U-shaped heat pipes with a diameter of 6 mm, the upper part of which is equipped with a heatsink consisting of forty aluminum fins *0.5 mm thick* (distance between fins 2 mm). To enhance heat transfer, the technology of direct contact with a polished pipe surface with the processor heat spreader...cover is used. The aluminum heatsink is blown by a 120 mm fan with PWM control and a durable Hydro Bearing dynamic bearing. Its rotation speed can vary from nearly silent (900 RPM) to increased (1600 RPM), at which an impressive airflow of up to 1.57 m³ per minute is ensured. |

A very good cooler, my xeon e3 1230 v2 at idle 27-30 degrees in the AIDA 64 stress test, the temperature did not rise above 58 degrees. Easy installation on socket 1155, three tubes, it's inaudible at low RPM Not found yet.  Petr Sustretov: use Deepcool GAMMAXX 300 few months |
I stupidly can’t hear the computer turning on Quiet, cools well, it can spin up to a maximum of 1350 rpm Difficult installation, it was possible to install normally only with the board removed  oleg: use Deepcool GAMMAXX 300 less than month |
The model is not bad, I recommend it Price noise level metal fasteners looks pretty good 3 copper heat pipes factory-applied thermal paste very low vibration decent packaging. Protected on top the mounting for AMD is a bit tight. I was afraid of breaking the board when installing, barely removed it to change the thermal paste. Noise at maximum speed. But it's all worth it because the hardware doesn't run as hot. use Deepcool GAMMAXX 300 few months |
Timeless classic
Due to the low cost of Deepcool GAMMAXX 300 has been one of the most popular tower coolers for many years in a row. Its price is commensurate with simple non-tower coolers like Deepcool Gamma Archer Pro rather than towers from other brands.
Everything ingenious is simple
The GAMMAXX 300 has not lost its relevance even after the release of the AMD AM4 platform, which, due to incompatibility with the AM3 + socket, put an end to many other coolers. The GAMMAXX 300 is fastened not with the help of a back plate (backplate), which AM4 has a different size, but with a universal latch. Thanks to this, the cooler is also very easy to install. The claimed noise level is only 21 dB, but in reality the fan is far from silent, although still within comfort limits.
People's Choice
It will not be possible to install the GAMMAXX 300 except on Intel LGA2011-v3 and 2066 processors, since they require a separate backplate that is incompatible with LGA1150 and 1151. However, the loss is small: a cooler with only three heat pipes cannot be installed on processors with a TDP of 140 W recommended. But Deepcool GAMMAXX 300 is great for building a quiet PC with an Intel Kaby Lake processor (up to 91W) or AMD Ryzen (up to 95W), even if you plan to overclock it a little.
