Temperatures
We're using Metro: Last Light for our thermal benchmarks. This should be a good representation of a high-end graphics workload. As a bonus, it's incredibly repeatable and easy to loop over and over through the built-in tool.
After publishing Does Radeon R9 290X Behave Any Differently In A Closed Case?, we decided to test these cards on an open bench table and in a closed case, since we found that dropping them into the right enclosure helped lower temperatures thanks to optimized airflow.

Temperature Graphs
These graphs slow how the temperatures change over time, influenced by the heat sink, the fan, and the firmware's fan profile.
Asus' R9 290X DirectCU II OC has a bit of a problem; its cooler was actually designed for the larger GK110 GPU on its GeForce GTX 780 Ti board. You can see this in the image below, where two of the heat pipes don't tough Hawaii at all, and two others make partial contact.
Sapphire solves this with a group of three heat pipes that better fit AMD's GPU. The result is made clear in our testing.
