Why Buyers Choose It
- The temperature display gives a direct CPU temperature readout on the cooler itself.
- The listed socket support covers several Intel and AMD platforms, which reduces the need to match a single socket family.
- The 120mm fan size and 155mm heatsink height are useful reference points when checking internal case space.
- PWM intelligent temperature control is stated, so the fan is intended to respond to temperature demands during operation.
How It Works
- Install the KF420 DGT radiator, then allow the software installation prompt to open automatically.
- Authorise the software installation to proceed.
- Fit the cooler using the matching installation platform or fasteners supplied for the supported socket type.
- Use the user manual for the installation kit and mounting guidance.
Real World Use
In a typical build, this cooler sits on the CPU and uses the listed fan, heatpipes and mounting hardware to manage heat while the temperature display shows CPU temperature information. The 155mm height is a useful check if your case has limited cooler clearance.
What To Know Before You Buy
Check that your motherboard socket matches one of the listed Intel or AMD platforms before ordering. Also review the 120 x 68 x 155 mm heatsink size and the 120 x 120 x 25 mm fan size against your case space. If you plan to use the included thermopaste, be aware that it may be difficult to apply if it has high viscosity or hardness.
Pros: It combines a temperature display with listed support for several Intel and AMD sockets.
Cons: The thermopaste may be difficult to apply if it is thick or hard.
