Is there any tool that can help me to monitor the temperature of my ATI Radeon HD 5870?
I think it is overheating, but to be sure I'd want to monitor the temps of the card.

How can I do this? (I'm running Mavericks)

None of the two apps showed me the temps for the graphics card... :(
Very strange that there is NO WAY to monitor the GPU temps, not even from the Mac Edition GPU's! Why? :confused: I've been searching a lot on forums for a tool that does it. I use iStat, but only CPU's are monitored...

So, Dr. Bresink said that SMC in MP does not communicate with GPU sensors at all. OS X graphics drivers also do not provide sensor reading (Windows ones do), so monitoring software can't access it in any way.

So, if you want to see your GPU temp in OS X, you got to bug Apple to add sensor support to graphics drivers...

Thanks for your update! But very strange indeed that such a vital organ can not be monitored in MP/OS X. I could not come up with one good reason for not monitoring GPU temps... :confused:

Does it change itself under load? I'm asking, because Unigine Heaven 4.0 has GPU monitoring as well, but it always shows 39-42C, like on your screenshot, no matter what card I have installed.
42C would be pretty low for Q4000, usually it idles at ~55C and goes up to 90C under load (CUDA).

Installed Magican:



NOTE: I have both the PC GTX-670 and 8800T Mac installed, while only the GTX is listed.

idle temp -> ~52C
gpu load under BF4 for Mac -> 53C :confused:

Can't be right? When in Windows temps go up till ~80C when card is stressed with i.e. Tomb Raider 2013.

Certainly not. Seems it does show "something", but same as Heaven 4.0 it doesn't work as it should.

MacBook's GPU Diode is read by SMC, unlike MP's GPU sensor, so sadly it's not relevant to this thread.
