Mini-ITX Copper Cooler, 28 mm Tall

The Dynatron K2 is a low-profile CPU air cooler built for Mini-ITX systems. It mounts vertically on Intel LGA 1156, 1155 and 1151 sockets using a copper heatsink and a 75 mm dual-ball-bearing fan. The total assembly height is 28 mm, fitting tight chassis clearances.

Suits compact Intel builds; not for other sockets

This cooler serves builders using supported Core i3, Core i5 or Pentium processors on the three listed LGA platforms. Buyers with different Intel sockets or non-Intel platforms cannot use this cooler. It also does not suit cases that require a cooler taller than 28 mm.

28 mm maximum cooler height decides fit

The single specification that determines compatibility is the 28 mm overall height. Measure the space between the motherboard and the side panel or any overhead component; if the gap is 28 mm or less, the K2 will install. If the gap is smaller, a different low-profile solution is required.

Questions sur cet article

Which socket version should I pick for my Intel Core i5-660?

The cooler supports LGA 1156, 1155 and 1151; your i5-660 uses LGA 1156, so this single model covers it.

What does the 44.0 dBA noise level mean when the fan runs at full speed?

At 100 % duty cycle the fan spins at 4000 RPM and produces 44.0 dBA, which is audible but typical for a compact 75 mm cooler under load.

How does the 4-pin connector control the fan speed range?

The 4-pin PWM header lets the motherboard vary the duty cycle from 20 % (1000 RPM, 6.0 CFM, 21.0 dBA) up to 100 % (4000 RPM, 11.9 CFM, 44.0 dBA).
