Macvidcards, I'm using uningine to stress test the Titan X you flashed for me. Do you know of an app to monitor its temps? Istat menus is a no go.
[doublepost=1463753755][/doublepost]So, I ran a 30 min geek bench stress test. CPU A got up 90c while CPU B topped at about 84c, what bothers me is the fan never went above 1600rpm. IOH stayed level throughout so no problems there. Any thoughts anyone?
That seems a bit high to me. The temperature usually stay at around 85C. Not sure if the dual processor model will allow the CPU temperature to go up for another 5C. Anyway, the 85 is observed from my W3690, since the X5690's temperature is 10C higher than my W3690. May be the system automatically adjust for that and allow the CPU run few degree warmer and keep the fan as low as possible. (This is normal, the SMC will try to keep the Mac Pro as quiet as possible, but just maintain the CPU at a temperature that not overheat)
Anyway, as long as it's stable, there is not much to worry about, the Intel XEON are very reliable. They will throttle themselves if require.
On the other hand, If you want better cooling, you may install the fan control software and setup your own fan profile.
For GPU temperature monitoring. You need FakeSMC in OSX, I personally won't recommend it, a bit too complicated to setup. Therefore, the next option is to run the test in Windows. Unigine benchmark software will display the GPU temperature in Windows automatically.
