Sapphire Vapor-X R9 280X TRI-X OC Testing:
Temperature testing will be accomplished by loading the video card to 100% using Unigine Heaven Benchmark Version 4.0, with MSI Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920x1080 using 8xAA and a five-run sequence to run the test, ensuring that the maximum thermal threshold is reached. The fan speed will be left in the control of the driver package and video card BIOS for the stock load test, with the fan moved to 100% to see the best possible cooling scenario for the overclocked load test. The idle test will involve a twenty minute cool down, with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running overclocked.
- Monitoring with MSI Afterburner
- Unigine Heaven 4.0 1920x1080 8x AA
- 5-run sequence
- 20-minute idle duration
- Temperature measured in degrees Celsius
Where Sapphire earns its keep with the Vapor-X cooling solution is when you put the card under a load. It is the coolest running card under load in the comparison field and is much cooler than the other factory overclocked and custom cooled R9 280X cards. Sapphire's Toxic Edition R9 280X uses a similar cooling solution, but the Vapor-X design takes that concept to another level by using three same sized fans and adding a massive vapor chamber to the base of the heat sink that really pays dividends.
Ramping up three fans is going to generate some noise. In this case the noise at 100% fan speed is not bad when compared to the squirrel cage fans used on reference cards. When the VBIOS controls the fans, the card is dead silent under load locked away in the chassis.
