AlanHo Posted February 20, 2008 Report Share Posted February 20, 2008 I have a Vista computer with a Q6600 processor, ASUS P5KC Mobo and Antec P182 case. I have Speedfan installed plus the third party Vista sidebar gadget called Speedfan Meter.My Antec case came with three 120 mm dia quiet case fans connected to the PSU via 3 speed in-line control switches - they are not connected to the Mobo and can only be speed controlled manually - mine are set to the middle position where the fans are whisper quiet but still move plenty of air.I have a Zalman cpu heat sink and cooler which is connected to the mobo.Question 1Speedfan shows an AUX temperature of 119C. I presume this is a false reading resulting from the fact that my case fans are not connected to the mobo - but what does AUX normally represent - the temperature of what? Also what does the SYS temperature represent.Question 2I would like to test my system and cpu temperatures when running the cpu at 100% load for a considerable time. Is there any simple freeware that will do this - or is there a trick available using software already on the computer - like Office, Vista, etcQuestion 3Do my temperatures look reasonable in the screen shot below?

Mike567 Posted February 20, 2008 Report Share Posted February 20, 2008 The fan I got with my antec slk3000b 120mm fan was crap but another antec fan I brought which alters its speed according to the temp is brilliant!hotcpu will test the cpu though but i dunno about temperature.

Gagaman Posted February 20, 2008 Report Share Posted February 20, 2008 Phantom readings.Speedfan gets its readings directly from the monitoring chip and not filtered through the bios. As a result it reports all the readings that the chip is capable of regardless of whether there is a sensor there or not. Just open the config settings and uncheck those readings.You could also try running another temp monitor tool like Pcwizard2008, CoreTemp, Everest, probably even a utility that came with your motherboard (Asus Probe???)I f the temps are measured correct, your temps are ok, I think. I got around 33°c on my quad6600 with 100%cpu load, running folding @home. This puter is watercooled. Room temp is 22°CTo stress your pc, folding@home is good and you are helping science with it Also prime2004 is used to stress your cpu Quote Link to comment Share on other sites More sharing options...
AlanHo Posted February 20, 2008 Author Report Share Posted February 20, 2008 Thanks gagaman.After playing with Prime 2004 I found that it only pressure tested cores 0 and 1. I found a link via google to set it up to run two copies - the second being configured for cores 2 and 3. It was a bit of a chore each time you wanted to use it - but worked fine once it was set.I then found on an overclockers forum a reference to the latest version of Prime 95 which now support 4 cores - I downloaded it and it proved to be much easier for me to use.I have been running the torture test for 3 hours and the highest core temperature reached was 41C on core 0 - which I am happy with. Core 0 is permanently about 5C higher than the other three - whether it is due to it being loaded more or the cooling is not as good in that area I know not.Mike 567I was aware before I bought the Antec case that the fans were not designed for connection to the mobo because a friend has the same set up bought a few months ago. He chucked out the antec fans and replaced them with 3 wire jobs connected to the mobo - but finds that the speeds hardly ever vary and he now considers it a waste of effort. Hence I decided to stick with the Antec standard which works fine.I would still welcome advice on the source of the temperature signal for the AUX and SYS references in Speed Fan.

Gagaman Posted February 21, 2008 Report Share Posted February 21, 2008 your temps on prime are good indeed.I have a q6600 procesor on an asus maximus mobo. Overclocked from 2400 to 3000MHz. Its watercooled.Here are my temps under full cpu load: Quote Link to comment Share on other sites More sharing options...
AlanHo Posted February 21, 2008 Author Report Share Posted February 21, 2008 your temps on prime are good indeed.There has been a development which has left me a bit concerned. I downloaded the new beta version of Speedfan and ran them both side-by-side. The beta version gives temperature readings 15C higher than version 4.33. I then downloaded and ran a programme called Core Temp - this tends to agree with the beta version of Speedfan.Here are screen shots of the 3 programmes with the computer idling - CPU at 15% . See next post for screenshot of temps at full load. Quote Link to comment Share on other sites More sharing options...
AlanHo Posted February 21, 2008 Author Report Share Posted February 21, 2008 Here are screen shots of the 3 programmes with the computer at full load - CPU at 100% .My dilemma now is - what do I believe and do I have a cooling problem.

Gagaman Posted February 21, 2008 Report Share Posted February 21, 2008 I did the test you did on my puter. Also a significant difference...Don't know really which is right... The new speedfan is beta so, there could be some glitches. On the other hand, pcwizard 2008 confirms these temps... EDIT: nevertheless, none of these temps should be very worrying. Depending on which core stepping you have, max. temps for the Q6600 are 71°C (GO stepping) or 62.2°C(B3 stepping). According to your coretemp information, you have a GO stepping.Source:http://processorfinder.intel.com/details.aspx?sSpec=SLACRhttp://processorfinder.intel.com/details.aspx?sSpec=SL9UM Quote Link to comment Share on other sites More sharing options...
Gagaman Posted February 21, 2008 Report Share Posted February 21, 2008 I also dl. Core Temp, this are my temps on 100% cpu load:Seems the speedfan beta is monitoring the temps far better than the not-beta version... Quote Link to comment Share on other sites More sharing options...
Raddy Posted March 18, 2008 Report Share Posted March 18, 2008 Speedfan is off by 15C for C2Q's, I'm not actually sure why. You can create a 15 degree offset manually in the configuration, or you can use a program like CoreTemp. I discovered it when my air-cooled, overclocked Q6600 was running about 10F cooler than room temperature B) Quote Link to comment Share on other sites More sharing options...

I too have Coretemp om my computer but prefer Speedfan because I have a sidebar gadget in Vista that continually displays the selected Speedfan data. Coretemp displays the info it in the task bar - but the text colours are unfortunate and do not show too clearly. Quote Link to comment Share on other sites More sharing options...
Big Elf Posted April 7, 2008 Report Share Posted April 7, 2008 Core Temp 0.97.1 allows you to change the colours of the temperature readings for each core in the system tray (Options, System Tray Setup, Set Text Color).http://www.alcpu.com/CoreTemp/CPUID Hardware monitor is pretty good for temperature readings too:http://www.cpuid.com/hwmonitor.php Quote Link to comment Share on other sites More sharing options...
