wrong temperature on macpro1.1 with x5355

[sak99]

Hi,

Macs fan control shows incorrect cpu core temperature on a apple macpro1.1 with upgraded cpu's (changed to xeon 5355). xeon 5355 is not recognized by apple firmware. Do you think this is a bug with macs fan control or a consequence of the fact that I use unrecognized cpu's?

Some more details: When cpu's are under load, macs fan control shows lower core temperatures.

Thanks

and this is a few minutes later with the same load:

At this point open hardware monitor (another software) shows temperatures around 77 degress for cpu a, and values above 80 degrees for cpu b which I believe to be more sensible.

Note: the machine has a forced install of newer (unsupported) bootcamp drivers for windows 7. Officially supported drivers are available only for windows xp and windows vista (and that was the reason that I have installed macs fan control - I dont think that unsupported new bootcamp drivers make a sensible control of the fans).

Note: An error message that appears at system startup which I believe to originate from macs fan control is in the attachment.

Thank you for the info! This issue will be fixed in 1.2 version soon

Please run this test now:

Hi,

Unfortunately the commands failed as follows:

sak99s-Mac-Pro:macsfancontroltest_runTest sak99$ sudo kextload macsfancontrol.kext
/Users/sak99/Desktop/macsfancontroltest_runTest/macsfancontrol.kext failed to load - (libkern/kext) requested architecture/executable not found; check the system/kernel logs for errors or try kextutil(8).

I don't know if I did anything wrong or if it's just that kextload failed because the OS does not recognize the cpu (all that it recognizes is that the machine has 2 processors and a total of 8 cores, but the processor is unknown.)

Thanks,

[Steven]

This tool requires OS X 10.8

Please post a screenshot of MFC window when CPU A/B is loaded at 100%

[sak99]

OK, let's see what I can do. Pictures are in the attachment.

The first one (which is displayed second for some reason) was taken roughly one minute after starting POV-ray with their benchmark image, and the second one was taken a few minutes later.

Kind Regards,

Here's another (at the end of rendering task):

Thank you, the issue will be fixed soon in 1.2 version

[suncatalyst]

im also seeing this bahavior on my Macpro3,1.

with the system loaded to 100% , my temps drop , when i unload the machine , at idle there Higher.

just like like the gentlemen in this thread with a Macpro1,1...
