Sabr Posted April 7, 2007 Share Posted April 7, 2007 Yeah, you should trust your BIOS temperatures. My BIOS reports 23*C. Then I go into OSx86, and it has jumped up to 52*C. Definitely not correct. Link to comment Share on other sites More sharing options...
bigcletus Posted April 8, 2007 Share Posted April 8, 2007 Ok, I feel better now I did check the bios and it was reporting at least 10 degrees cooler than in osx. I think I might still get a better heatsink and fan later on though as I am using the stock one. Link to comment Share on other sites More sharing options...
domeproject Posted April 10, 2007 Share Posted April 10, 2007 hello guys...i have one question: how can i read the temperature of a AMD CPU? It's a Turion64 X2 TL-52. In windows i've checked the sensors and the thermal zones and they were called TZ_1 , TZ_2 and TZ_3. I also checked a thermal kext in OSX and it shows that those zones are recognized and "something" is read from them (a decimal number with 4 digits). Can they be used to monitor my temps? Thank you Link to comment Share on other sites More sharing options...
mrheat Posted April 11, 2007 Share Posted April 11, 2007 same here, using a intel915 btx shuttle SB86i xpc.. since 10.4.9 i see "thermal-zone" in ioreg and a value that changes if under load but it updates just every 5 minutes or so, and theres no matching "HW-Sensor" i think thats the reason why we cant use all the temperature tools? this stuff seems to be top secret, no docs to find about this on adc or somewhere else.. my front and ps fan have changing values too, post up some screenshots later.. "smart" temp regulation works pretty good, although it gets a bit too hot for my opinion.. Link to comment Share on other sites More sharing options...

thysm00 Posted June 25, 2007 Share Posted June 25, 2007 It does work perfectly for me, I get Disk temperature (sata2 spinpoint disk 250G), and temps of both cores (i'm using a 4300 core 2 duo about 42° on IDLE). BTW i'm under 10.4.8. Link to comment Share on other sites More sharing options...

thysm00 Posted July 20, 2007 Share Posted July 20, 2007 Hi all, I changed my motherboard from a asrock 775i945gz to a msi 945gm3-f and the temps increased from 40-50 to 60-70... I'm using the same heatsink and fan, the same case, same processor, same everything, and i don't overclock or anything, so maybe there is really something wrong with readings in temerature monitor.

rahulmac Posted July 23, 2007 Share Posted July 23, 2007 i have installed Mac OX on my HP dv 1677ea. The Temperature Monitor shows Between 55-63 C always while in windows its about 30-35C i want to know whether its harmful for the CPU or whether the temperature monitor is showing wrong temp. when i just boot my PC temperature monitor shows 28C and its goes upto 67c in 5min and then comes down and settles around 60 always.Whats the Max. allowable temp. for my processor?

Thanks. Max temperature for _continious_ work is usually around 75C (depends of CPU), but I saw Intel's processor with dead fan working flawlessly at as high as 95C! Most modern CPU have thermal protection (throttling etc.) built in them, but they will work with the performance penalty in such circumstances. In extreme situations the CPU will shutdown. Even so, processor average life at operating temp (defined by manufacturer) will be decreased with raised temperature. Some components will die two time faster on average if temp is raised by 8C for example. On very high temps (above 100..120C) average CPU will be permanently damaged in very short time. I think that root cause of your problem might be non-fuctional CPU power management and Volt/freq scaling. Do you have AppleIntelCPUPowerManagement.kext loaded? Some kernel dont work with this kext - and my CPU is much hotter without it! Some settings in BIOS can also make CPU hotter (QuietFan etc.) You should also try to enable SpeedStep if you can (especially on laptop). There are people with much more knowledge than me about this topic, and I am encouraging them to join this discussion - and to correct me if I said something wrong.

blagec Posted July 24, 2007 Share Posted July 24, 2007 Great too. My CPU shows about 20-25 °C, but I thinks this can't be. System is about 34 °C. Is this real or does the tool make mistakes by reading temperatures of my MSI board? Although the Sys temp is fine, I never saw an oridinary CPU working on 20C (excluding short period of startup). I think that temp reading is aligned for Intel CPU, and since you have AMD readings are lower. Anyway, you can make simple correction: - Enter BIOS: single core CPU in bios is at 100% load, wait for 5 min, and remember max CPU temp(T1) in BIOS. Remember m/b temps & Vcore also. - Boot OSX, open console - Leave machine idle for 5 min to reach lowest temp - type thermo-oneshot (or thermo) in console (CPU temp in the response should be same as displayed by the widget) - Apply 100% load on the CPU (this can be achieved by typing: while true; do echo 1; done) and see if temp is rising fast. If so, that is CPU temp, but should be recalculated. Wait for another 5 min under heavy load, and record maximal temp (T2). NOTE: On full load M/B temp will rise as well as CPU, but much slower. You can easily change widget source to multiply reading by factor of K=(T1/T2) and display approx AMD temp. K should be around 2, I think. You may place Intel/AMD checkbox or correction factor sliders (multiplier K and constant C: Treal = K*Treported + C) in widget settings for example.

Stony Posted July 24, 2007 Share Posted July 24, 2007 Well, with about more than 73 % to 80 % CPU load, CPU temp don't gets over 23 °C and System dont over 35 °C. I didn't added any multiplier or similiar yet.. but the temp don't rises much.. strange.. any other way to add new sensors or something? Link to comment Share on other sites More sharing options...

ej25power Posted April 12, 2008 Share Posted April 12, 2008 Seems to work pretty well with my GA-EP35-DS3P and Q6600. Sometimes the temps will blank out on some of the cores, but when they are there (for the majority of the time) they look fairly accurate. BIOS reads the temp at 31° at idle and Temperature Monitor reads each core 26°-30° at idle. I'm not sure if the BIOS just looks at one core or averages the temperature.

DannoXYZ Posted April 21, 2008 Share Posted April 21, 2008 Remember with the built-in CPU-sensor in the Conroe and later chips, that it's actually reading core-temperature as opposed to surface temperature. This will be about 10-20 degrees-C higher than what the motherboard temp-sensor reads (on those boards that actually have a CPU temp-sensor).
