Low-profile 41 mm cooler for legacy Intel sockets

The Dynatron K5 is a 92 mm aluminium tower rated for CPUs up to 77 watts on LGA 1156, 1155 and 1151 platforms. Its 41 mm height suits slim chassis where standard coolers will not fit. A captive screw backplate and pre-applied TIG830SP compound simplify installation. Builders targeting newer sockets or higher TDPs should look elsewhere.

Three-speed 2-ball bearing fan curve

At 1000 RPM the fan moves 14.98 CFM at 14.7 dBA, rising to 33.8 CFM and 22.7 dBA at 1800 RPM, and 46.96 CFM at 29.8 dBA when driven to 2500 RPM. The 4-pin connector enables PWM control across the full range. Airflow above 46.96 CFM is not available from this unit.

Horizontal aluminium fin stack limits

The horizontal fin orientation and 41 mm profile restrict heat dissipation to the rated 77 watts. No heat pipes or vapour chambers are present to extend thermal capacity. The 92 x 25 mm fan frame leaves no room for a second fan. Systems exceeding this thermal envelope require a larger cooler.

Questions about this item

Will the 41 mm tall K5 fit inside my existing slim chassis that uses an LGA 1151 motherboard?

Yes, the cooler stands 41 mm high and supports LGA 1151, 1155 and 1156 sockets, so it clears most low-profile cases that accept that mounting pattern.

How can I confirm the 2-ball bearing fan is spinning at the correct 2500 RPM under full load?

Connect the 4-pin PWM header to the motherboard, then monitor fan speed in BIOS or a hardware utility; at 100 % duty cycle it should report 2500 RPM and 46.96 CFM airflow.

Does the box include the interference-free backplate and pre-applied TIG830SP thermal compound, or must I buy them separately?

Both are supplied — the captive screw backplate and pre-printed TIG830SP compound come in the package, so no extra purchase is needed for installation.
