BFG Tech GeForce GTX 285 H2O

How we tested

As always, our aim is to deliver a clean set of benchmarks. Each test repeated three times and an average of those results is what we’re reporting here. In the rare case where performance was inconsistent, we continued repeating the test until we got three results that were consistent.

The tests performed are a mixture of custom in-game timedemos and manually played sections with FRAPS to record the average and minimum frame rates. We strive to not only record real-world performance you will actually see, but also present the results in a manner that is easy to digest.

Water-cooling setup

To test this card we fashioned a graphics card-only water-cooling loop from components that we had in the Lab. We settled for a single 120mm radiator, a small reservoir, a powerful pump and 1/2in inner diameter tubing. Here’s the full setup:
  • Danger Den Black Ice Pro radiator (single 120mm)
  • Laing D5 pump
  • Swiftech MCRES-Micro reservoir
  • 1/2in inner diameter tubing
  • De-ionised water with Swiftech Hydrex additive
