nVentiv (also known as Chip-Con) released their first phase change unit back in 2002, called the Prometeia. It offered subzero cooling unlike any other solution on the market back then; When competition raised its head (asetek) they released new units and changed their company name and product line. The Mach II was born, followed by the Mach II GT and Mach II ST. The old Prometeia unit was renamed to Mach I and it is this piece of hardware I’m going to give a power boost today. Webmaster Alex from the Belgian overclocking website Overclex
send me his unit for a complete overhaul. [A French version of this article is online at Overclex]
This is how you average run-of-the-mill nVentiv freezer looks like:
All the different Mach revisions used similar hardware, like the Danfoss NL11F compressor:
And the freezing head (a.k.a. evaporator), which consisted of a black plastic box with the evaporator insulted inside with PU foam. The different revisions of the Mach improved performance and while the mounting system was certainly not the best, it got the job done.
Here’s an overview of the different evaporator heads used by the Mach 1 and Mach 2 from nVentiv.
Now I’m not going to talk you through the history of retail phase change units, I’m here to show you how I’ll upgrade nVentiv’s first Subzero machine so it can easily match the Mach II GT and asetek Vapochill LighSpeed performance wise!
