in some screenshots of atitool there is a temperature readout in the bottom. my ati tool running on a aystem with a 1900xt doesnt show anything. does the pure ati 1900xt not have a temp sensor?
Of course it has a temperature sensor. Hope yours is not borked. It should show the temps in the "Overdrive" tab in ATI CCC. Or try using ATITool from atitool.techpowerup.com. Good luck.
