We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.
The MSI GTX780 Lightning cooler is excellent, maintaining a temperature of 70c throughout our testing. The GTX Titan 6GB is also an impressive cooler considering it is a single fan. It runs around 3-4c hotter under load. The Sapphire HD7970 6GB Toxic Edition is the hottest running of them all, holding around 75c when gaming.
