Vapor chamber heatsink

The Dynatron R23 is a CPU air cooler built around a vapor chamber base paired with aluminum stacked fins. It measures 5.25 by 4.25 by 3.5 inches and weighs .97 lbs. The unit is supplied as a heatsink only, without an integrated fan. This design targets systems where a separate airflow solution is preferred.

Passive cooling builds

The heatsink suits builders assembling passively cooled or semi-passive workstations who will add their own fan or rely on chassis airflow. It also fits replacement scenarios where the original mounting hardware is retained. Buyers needing an all-in-one cooler with a pre-installed fan should look elsewhere.

Vapor chamber base

The defining specification is the vapor chamber base combined with aluminum stacked fins, which spreads heat from the CPU lid into the fin array. This construction determines the thermal capacity available before active airflow is added. Verify that your socket mounting pattern matches the heatsink footprint before purchase.

Questions about this item

What mounting hardware is required to install the R23 heatsink on my CPU socket?

The R23 is supplied as a heatsink only; you must provide the correct retention brackets, back-plate and screws that match your specific motherboard socket.

Will the R23's 5.25 by 4.25 inch footprint clear tall RAM modules or VRM heatsinks on an older board?

At 5.25 by 4.25 inches the base covers a large area; measure the space around your socket to confirm clearance for memory sticks and voltage-regulator coolers.

How can I verify the vapor chamber base is making proper contact after mounting the R23?

Check that idle and load temperatures drop to expected levels for your CPU and that the heatsink feels evenly warm across the fin stack during operation.
