14 DAY TRIAL // Although ZEROtherm is not as popular as OCZ or Thermaltake, it has managed to surprise overclockers in the past with their butterfly-shaped cooler, the massive copper BTF90. ZEROtherm is a marketing division of APACK, a Korean cooling solutions provider that targets at the OEM market and is not represented on the retail sector.
The Nirvana NV120 comes fully assembled out of the box. This means that the cooler comes with the 120-millimeter fan already fastened. Moreover, the fan can not be replaced, because of its special model that makes it look like it is growing out of the cooler's fins. The cooler still keeps the same fin shape with extensions wrapping around the fan, as in the BTF90 model, although they did not outline the butterfly shape.
Nirvana is made of nickel-plated copper for the base and heatpipes, with aluminum fins. While the BTF90 was made of massive copper, the Nirvana proves to be heavier than it, although it is made of aluminum and nickel. The cooler supports both Intel and AMD sockets, and comes with mounting hardware for Intel Socket 775 and AMD Socket 754/939/940/AM2. The cooler comes with its own ZEROtherm silver-based thermal compound to make the thermal transition from the CPU to the cooler.
Intel socket 478 users, wave your hands goodbye, as there is no proper solution to fasten it on the CPU socket. And if it did, we doubt that you would need that much ventilation power, even for an overclocked Pentium 4.
Another interesting addition to the fan is the NV120 external fan controller, that allows the user to manually throttle or calm down the powerful 120-millimeter fan, according to the desired temperature and noise level.
