Thermal Sensor?

I have a Turbo KT133 board and it has a southbridge chip made by VIA. The southbridge is VT82C686B. i was using Motherboard Monitor and it says that there is 3 thermal sensors on the motherboard. I know one is for the CPU temperature but I'm not sure what the other 2 are measuring. Does anyone know where the other 2 are? Where is the thermal sensor that measures the CPU temperature located at? Thanks in advance.

Assuming you're referring to one of MSI's original K7T Turbo models, only two temps are monitored, CPU and chassis. The CPU sensor is a thermistor mounted on the circuit board under the socket-a. Hope that helps.

Will Not Boot from Install Disc & 4SNS/1/40000000: TG0D - Thermal Sensor?

*Will Not Boot from Install Disc*
I used the "option key" approach with the gray start up disk. At first it ejected the start up disk. Then I nudged the disk back in the machine and it showed on the screen as an option. I clicked on the start up disk image and it finally loaded.
But, it won't accept the start up disk when holding down the "C" key at restart.
*4SNS/1/40000000: TG0D*
I did an Apple Hardware Test and received the following diagnostic:
Version: 3A121
Test Suite: Extended Test
Loop Count: 2
Result: Failed
Failure code: 4SNS/1/40000000: TG0D
*Thermal Sensor*
A search for the failure code 4SNS/1/40000000: TG0D brought up an Apple Discussion topic entry stating: That error code indicates a problem with a thermal sensor. It could be not working or possibly not connected. You will need to take it to Apple for repair.
Would a thermal sensor have anything to do with it not starting up when holding down the "C" key at restart? What are thermal sensor problem symptoms?
*User File Folder Opened Up*
The machine also starts up with my user file folder opened up rather than with a blank screen as it normally should
I completed a DiskWarrior rebuild on the disk and verify disk shows it is fine.
Any suggestions on what to do next with these issues?

The answer was in your post: "You will need to take it to Apple for repair."

Where can I buy a new 3.5" SATA HDD with the extra thermal sensor port for my late 2009 imac?

Depends on the original drive. According to OWC, at least last time I checked some months ago, any current WD drive they sell (up to 2 TB?) will be able to be swapped directly. I am unable to confirm this personally. But, even so, that was a while back. You should check with them again on this. As for Seagates, that might not be so simple.
This is the original article on this from them.

If you find a drive that OWC sells and is certain will swap in directly, you can see if newegg.com has it for less.
This one that OWC sells will swap in directly, according to them.

Mac Mini Mid 2010, thermal sensor question...

Hi,
So after having opened my Mini a couple of times already (out of warranty) I sadly have to announce that I have joined the "Oops I damaged the thermal sensor club".
The DVD broke down, it was no longer accepting discs and I thought I would replace it with a second HDD bay. So I did and obviously forgot how fragile these thermal scukers are and snapped it in half. I know what I need to do but I'm having issues finding the optical thermal sensor 076-1370 at a reasonable price (including shipping). Does anyone know if any thermal sensor will work, e.g one of the HDD sensors for the mid 2010?
It's not a problem if the cable is too short. I can just re-solder it to fit but I'm unsure wheter it's the same thermal sensor for HDD's as it is for the optical sensor. They look the same to me.

Non thermal sensor RAM

Greetings,
From the OWC memory upgrade page, it is stated that its DDR3 RAM are with thermal sensors. I wonder now whether RAMs without thermal sensor are compatible. I'm looking at Kingstion value ram at the moment. Thanks

George, you didn't mention you have special needs and a vendor that ships to Asia. You mentioned OWC, so thought that was where you were thinking of buying or have used before.
Australia and Japan, So Korea, and you haven't found a vendor?

X230: thermal sensor locations

Hello all,
Does anybody know where can I find information about physical location of all 6 thermal sensors on X230? I tried to google and look in the user guide, but no luck...
Thanks!

morgwai,
which sensors are you talking about? Test tools say about core #0, core #1 sensors you've mentioned. Also we see memory banks, CPU Package, IA/GT Cores sensors. Or do you mean sensors on the systemboard manufacturer adds - under CPU/GPU, near wwan/wlan, on the board covers?

Thermal sensor physical locations

Hello,
I searched the forum for this information, but could not find any information. Please excuse me if this post is redundant.
I have a K7N2 (MS-6570) MB. I am using Motherboard Monitor and am trying to find out which thermal sensors are used to monitor which devices. I am also wanting to know the physical locations of these sensors. My current assumption is that sensor 1 in the Athlon core diode, sensor 2 is the CPU Socket, and sensor 3 is the general case temp. Can I be confirmed or corrected on this?
Thank you.
Shoes
You talk better than you fool!

Thanks for the info. I've got bios 3.7 and I don't get the deal with the temp. Is the the corrected version or is it still off? My temp used to read 57*C and now reads 37*C. Should this be 47*C?

Enabling Thermal Sensors on Conky

Hi everyone, Im having a hard time enabling the thermal sensors for my conky. I get only a cpu sensor which uses this script.
${color #888888}CPUTEMP:${color #CCCCCC} ${acpitemp}C
I've already installed lm-sensors and hddtemp.
What's the command for enabling them?
And by the way, the script above doesn't even move or rises...It stucks on 4O C...And I assume that this is a System Temp not the cpu temp..Correct me if I'm wrong.;)
All help would be appreciated... Thanks...all

Dunno about that specific one (acpitemp gives me nothing), but do you have anything in /sys/bus/platform/devices? Like:

fan3_min in2_input in5_min pwm1_enable temp2_alarm
fan4_alarm in2_max in6_alarm pwm1_freq temp2_input
My ambient temp reading, and root HDD are gotten with:
${platform it87.656 temp 2}, ${hddtemp sda}
The exact names may vary.
DE panel plugins may be helpful in figuring out which exactly is which. FI, I got a bunch of temps showing w/ XFCE's sensors plugin, then loaded my PC for awhile, to get what was what (except CPU and HDD). Quicker and easier than using conky or sensors for figuring them out.

Replace mid 2010 mac mini hard drive(s) and thermal sensor(s)

TL;DR: How do I swap SSd for HDD in Mid 2010 Mac Mini without Fan problems.
I'd like to replace both my Mac Mini HDD's with SSD's, but removing/repositioning* the factory thermal sensors will default the fan to full throttle! (I've had this happen on my other mid 2010 test machine). Has anyone successfully swapped out their drives and not had to deal with a system fan on Afterburner mode?
Note: on my test mac mini, I tried SMC fan control as well as SSD Fan Control apps and neither is able to change the fan RPM.
SMC Fan control (this is what I use on my macbook)
https://www.macupdate.com/app/mac/23049/smcfancontrol
SSD Fan Control: (suggested by others with similar thermal sensor/fan problems)
http://exirion.net/ssdfanctrl
* the position of the thermal sensors on the factory hitachi's is apparently important. In a test, I moved one a few millimeters and the fans defaulted to full speed.
Cheers!
Ken

I replace the HD on my 2009 Mini with no fan problems.
From your description I think yo have either a sensor or logic board problem. If the sensor was not attached to the HD and was "cold" then the fan speed would not increase if the HD got hot.
When you played around with sensor position what what the temperature of the sensor when you go the "right" fan speed and the runaway speed.

AMD K10 cpu thermal sensor

Does anybody know about K10 thermal sensor support in lm_sensors? In theis svn changes it's listed in 3.0.0-rc2 (http://lm-sensors.org/svn/lm-sensors/trunk/CHANGES), but I have no modules in my Arch x86_64.
Where could be the problem?

I installed the package, and sensors-detect says:

K7N2 delta thermal sensor / dual channel

Hi all.
I was wondering for what purpose my k7n2 delta ilsr has a thermal sensor (tape sensor) underneath the CPU, right in the middle of the socket... shouldn't the board read the temps directly from the CPU diode? Anyone knows?
I have also seen an interesting thing... I had 2 sticks of 512mb kingston in that board, in dual channel mode and last week I ran doom3's timedemo demo1, and I noticed that I got a 10fps lower result than those I had earlier, when I was running single channel with only one stick.. so I pulled the second stick out and installed it in the other dimm (didn't change anything in BIOS), wich uses the same mem controller that the first and ran timedemo again... As you might guess i got about 10fps more than the previous result I went searching it and i did find one article confirming this - http://www.theinquirer.net/?article=10384 And a LOT more saying the contrarylike this one! http://www.digit-life.com/articles2/nforce2-1vs2channels/
I found some potential explanations but I think 10fps is still a lot for those explanations, besides nVidia sold this as a high-end feature on this chipset... what the hell???

Quote from: dOP on 04-October-05, 05:20:51
The modules are kvr400x64c25/512, and they are at default timmings. I´ve been using one of them for about 1 year and it works perfectly. The other one is recent but it works flawlessly too. Howerver when they're together this thing happens. I'm not sure if this is a problem with the modules/kingston because it's so weird. I can't find any logical explanation, I'll keep looking... As you say Stu, kingston is a hit or miss, but hit and miss at the same time is strange. I'll do some research on those mushkin/crucial modules. Thanks.
They are not matched... Ill bet 1000 dollars that is why
Kingston absolutely requires the sticks be purchased in their "DUAL CHANNEL" (2 stick) package. I already went through that with Kingston a year ago with the K7N2-D2-P

Thermal Diode vs Thermal sensor ???

Hi there,
i have just fitted a coolermaster cooldrive to my pc. I am using the included thermal sensor wires to monitor the surface temo of my WD 1200JB hard drive. I am consistantly receiving at least 5 degree higher temp readouts from SpeedFan over the integrated thermal wires of the coolermaster unit on the hard drive. Ok so here it is.. which is the correct temp ? And where is the thermal diode sourcing its temps from the hard drive.. ?? Inetrnally or what ???
Thanking all in advance...

Yes speedfan does give temps for the HD's but I'm not sure where it senses it from, I would tend to think that your thermal diode would be more acurate.

Unable to detect a thermal sensor: lm_sensors and ACPI

HP Pavilion ze5600 laptop, latest Arch kernel, ran sensors-detect and this is the result:
Sorry, no sensors were detected.
This is relatively common on laptops, where thermal management is
handled by ACPI rather than the OS.
I tried "sudo modprobe thermal" and although successful there is no thermal entry in /proc/acpi . I also tried adding "acpi_enforce_resources=lax" to kernel boot line without success. I also attempted to insert the i2c-dev module before running sensors-detect, without success.
As I have not tried any other OS on this laptop I am unsure whether it does actually have a sensor but googling around others seem to have been successful. Any suggestions on how to proceed would be most welcome.

I'd love to see this thread solved as my Dell XPS L1502 has the same situation. A sensors-detect brings the same module as you but the sensors outputs temperatures for just 2 cores for an i5 should be listed, which are about 50°C (normal?).

The pwmconfig returns an error "no pwm-capable sensor modules installed".
Thanks for everyone contributing to this thread.

Macbook pro 13 2011 thermal sensor issue ,fan is making a **** lot of sound

I hav run the system hardware diagnostics it showed the thermar sensor issue .what would be the cost of it to be replaced

if you plan on getting it repaired at a repair shop, you would need to bring it there for an estimate.

Mac mini mid 2010 fan/thermal sensor connector issue

Hi,
so, the fan wont' power down in my mini (always on max when power on, smc reset no help, cpu not running hot); i opened the case and noticed that the connector for the heat sensor for the optical drive seems to be missing (cf. picture, if I have understood correctly, the connector should be where the red circle is, but there is just a wire that has been sittign under a piece of black tape, there is not even a housing for the connector.)
Now, two questions for the gurus:
- given that the housing also seems to be missing, is there any point in trying to get a new connector?
- is it possible to run the mini without the fan?

Yes, I know, but with these instructions http://forums.macrumors.com/showpost.php?p=5266108&postcount=144 the fan speed can be controlled; the warranty is gone, I suppose, and so could the CPU be, soon, but like I said, there seems to be no temp sensor present, and with full speed fan the mini is unusable anyway.
