Dynatron R-5 1U Active CPU Cooler for Intel LGA1150/1151/1155/1156/1200/1700, Copper Base, PWM Fan

For dense 1U server environments where every millimetre counts, the Dynatron R-5 delivers a focused cooling solution that doesn't compromise on thermal headroom. Its copper base and aluminium fin stack are engineered to pull heat away from high-TDP Intel processors quickly, while the PWM-controlled dual ball bearing fan adapts speed from a near-silent 1500 RPM to a forceful 6000 RPM as load demands. Pre-applied thermal paste simplifies installation, and support for six LGA socket generations makes it a versatile spare or upgrade for mixed fleets.

Highlights

• Supports Intel LGA 1150, 1151, 1155, 1156, 1200, and 1700 sockets
• Handles processors up to 165 W TDP for reliable server operation
• Copper base with aluminium fins for efficient heat transfer
• PWM fan from 1500 to 6000 RPM balances cooling and acoustics
• Dual ball bearing fan rated for long service life in 24/7 duty
• Pre-applied thermal paste reduces setup time
• Compact 1U form factor fits standard rack chassis

In daily use

Installed in a 1U rack server, the R-5 keeps sustained CPU temperatures in check even under virtualisation or database workloads. The 4-pin PWM connector lets the motherboard adjust fan speed based on real-time temperature, so idle periods stay quiet at around 18 dBA while peak loads receive maximum airflow of 38.5 CFM. The dual ball bearing design resists dust and heat better than sleeve bearings, extending maintenance intervals in dusty data centres. With a height of only 27 mm, it clears low-profile chassis without interfering with adjacent components.
