Know before you buy
This adapter allows you to mount your HEATKILLER Tube reservoir directly onto 120mm fan slots or radiators. It is designed to provide flexible positioning options when standard mounting points are unavailable or inconvenient.
Yes, you will need the HEATKILLER Basic Mounting Kit to complete the installation. This adapter serves as the interface between the reservoir and the fan or radiator, but the mounting kit is required to secure the reservoir itself.
While it is specifically highlighted for mounting the Tube 100 model onto 120mm fans, it is compatible with the HEATKILLER Tube series generally. Ensure your case has enough clearance for the specific length of your reservoir before installation.
Yes, the adapter is designed to align with standard 120x120mm mounting holes found on most PC cases, radiators, and cooling fans. It provides a secure, powder-coated steel mounting point for your reservoir.
