ARCTIC Accelero Xtreme 7970 Cooler Review

Today we are testing the card in a Intel Core i7 990x system, which is CPU watercooled and running at 4.8ghz. Room temperatures were maintained at 23c throughout.

Test System:

Processor: Intel Core i7 990x @ 4.8ghz.
Cooler: Danger Den Watercooling.
Motherboard: Asus Rampage III Black Edition.
Memory: 12GB GSKILL 2133mhz Memory.
Power Supply: Corsair AX1200W.
Hard Drives: Patriot Pyro 120GB & 2TB Samsung hard drive.
Optical Drive: Asus BluRay drive.
Graphics: AMD HD7970 with reference cooler and ARCTIC Accelero Xtreme 7970 Cooler.

The cooler is significantly better than the AMD reference solution, as expected. The idle temperatures drop from 36c to 30c, and when gaming, they drop from 79c to 60c. Very noticeable differences.

AMD reference coolers take some time to return the core to idle temperatures, often a couple of minutes, or more, depending on the environment. The ARCTIC Accelero Xtreme 7970 returns the HD7970 core to idle within 30 seconds. The reference AMD cooler takes 75 seconds to perform the same task. Bear in mind that the variables between the coolers at the same moment in time are often 20c+.
