The CG miner shows the temp for me :/
Also, what driver package are you using for these cards?
Windows 8.1 using 2 monitors on it. 13.251 drivers.
Temp shows in top left corner, simple google img search should show you how it looks with temp
Interesting, so hooking up a monitor to one of my two R9's, and now temp shows up! I want to run this headless, I wonder if a DVI to VGA adapter with no monitor, will be enough to trigger the temps.
