The base is impeccably even and boasts the absolute best finish quality:

There is the same 110x25mm fan (TT-1225A model). It is installed between two heatsink arrays in a metal stand:

The fan rotation speed can be adjusted with a small regulator that is not very convenient to work with. It is designed as a short “branch piece” of the main cable and allows changing the RPM in the interval from ~1300 to ~2000 with maximum airflow ~86.5 CFM and noise level between 16 and ~24 dBA. The blue LED highlighting is also there.

The new cooler can be installed onto AMD K8 and K10 processors with the help of the retention clip that should be inserted between the heatpipes and then catches on to the hooked edges on the standard plastic retention frame and locks securely with a tab. Installation onto LGA775 mainboards requires two retentions with plastic spindle-clips to be attached to the cooler base:

Thermaltake V1 AX is very compact at the base and the heatpipes coming out of it do not interfere with any mainboard components:

The cooling efficiency of this solution hardly depends on the way the cooler is positioned inside the system case. However, we could get 1.5~2°C better results when the cooler was installed with the heatpipes lying horizontally (the case stands vertically). It is not too much, but still. So, we performed out tests with the Thermaltake V1 AX modding cooler installed in this particular way:

You can clearly see the blue LEDs in the dark:

Thermaltake V1 AX MSRP is set around $45.
