xworm Posted December 11, 2013 Share Posted December 11, 2013 CPU T7500（2.2GHz）, SpeedStep works（from 600MHz to 2.2GHz with 200Mhz step），thanks for the article "Performance running with Fakesmc" CPU 42~46℃ （idle） under windows 48~52℃ （idle）under Mavericks GPU under Mavericks 65℃ （idle） 78~80℃ （10min 720P mkv） FAN speed doesn't show on HWMonitor, but from the noise, I'm sure it ran at higher speed than under Windows with same workload. Is the above status normal ? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted December 11, 2013 Administrators Share Posted December 11, 2013 I have roughly identical T° readings. my GPU T° can even get higher. I clean the fan regularly, I've renewed thermal paste and even used a copper shim over the nVidia chip but none of this made any difference as far as lowering T° is concerned. D630 keeps on running, so I just live with it... Link to comment Share on other sites More sharing options...
wern Posted December 13, 2013 Share Posted December 13, 2013 extract this SSDTs to your extra folder and restart, only for T7500 ssdt-T7500.zip 1 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted December 13, 2013 Administrators Share Posted December 13, 2013 What changes does this SSDT bring to the D630 because the T° issue is with the GPU, not really with the CPU? Link to comment Share on other sites More sharing options...
wern Posted December 19, 2013 Share Posted December 19, 2013 What changes does this SSDT bring to the D630 because the T° issue is with the GPU, not really with the CPU? CPU 42~46℃ （idle） under windows 48~52℃ （idle）under Mavericks I don't think that is an GPU issue Link to comment Share on other sites More sharing options...
Administrators Hervé Posted December 19, 2013 Administrators Share Posted December 19, 2013 nVidia GPU always runs hot in that machine, OS X making much heavier use of graphics acceleration than Windows. What changes does your above SSDT bring ? Better CPU power management, which OS X clearly handles less favourably than Windows? Link to comment Share on other sites More sharing options...
m3mb3rsh1p Posted April 6, 2014 Share Posted April 6, 2014 I replaced my Intel motherboard with an Nvidia version from ebay and have been successful in getting lower temperatures using copper shims. The motherboard came with a T7500.After much trial and error and following the "Performance tuning using FakeSMC..." article, my temperature readings are now:Lowest idle temp.: CPU - 36 deg. @796MHz; GPU - 55 deg. @168MhzHighest temp. Netflix HD: CPU - 62 deg. @2200MHz; GPU - 72 deg. @400MHzI used a 0.3mm shim on the CPU and 1.2/1.5mm?? shims (I don't quite remember) on the other two chips, all with Arctic MX-3. Hopefully this will keep my laptop alive for a long time.Thanks to everyone here for all their work. Link to comment Share on other sites More sharing options...
Axel-Erfurt Posted July 2, 2014 Share Posted July 2, 2014 Since the last Firefox Updates, my GPU temperature in Firefox is much higher than in Safari (+10) I have only 1 Addon in Firefox (Adblock) Link to comment Share on other sites More sharing options...
