TMPIN6 sensor Temperature is high using two different Utility software

i did scan the motherboard with my infrared camera and this temperature is accurate which is located in small area near the SATA port. the left bottom corner of the motherboard

should i worry about it

4,5,6 are all high. Ish. But thats also normal behavior for parts of the board under different conditions. Also you must take into account software. It's not perfect. It was written years ago, and at the time was great for what it was. Since then, there have been multiple vendors, multiple mobo's, multiple changes etc, all of which can easily add up to incorrect addressing. What is a sensor on one mobo, might very well be the Northbridge chipset on another board, according to address, so temps will be totally inaccurate. I can use that same software as you, my tmpin6 reads -125°C, tmpin4 reads 255°C, both of which are physically impossible on a mobo. SpeedFan does the same thing, as hwinfo64 or Hwmonitor. According to any software run...

According to any software run other than the bios or native MSI software, my psu has a 12v output of either 8.2v or 10.2v. Neither is accurate, the 12v output under loads is 12.18v according to my Fluke meter. 12.2v in bios.

That said, with 3 temps all running high, and you finding 1 spot that reports similar, and knowing there's no way to determine exactly what tmpin4, tmpin5 and tmpin6 are actually addressed to on your specific mobo, it's entirely possible, even probable, that those numbers are not accurate to that specific spot. A mobo as such only has a few sensors, very few actual components have built in sensors (like the cpu, gpu etc)

More than likely, that hot-spot next to the Sata port is part of the voltage regulatory circuitry to the Sata ports, of which your drives are running from. It's going to get warm with usage, the more the demand for voltage, the warmer it'll get.

Take the results with a grain of salt. I'd keep an eye on it, especially if you duplicate the conditions under which it was tested, or exceed them, but if you test again, when the pc is idle for a few minutes, and the temps are much lower, then chalk it up to normal usage.

ASmedia chipset in that picture. Those chipsets are all about usb and Sata control, it's what ASmedia does.

If you do not have ASmedia motherboard drivers loaded, but are using windows generic drivers, this can be a slight issue as the chipset will work, but struggle, causing it to work harder. The ASmedia drivers will streamline the process.

But either way, as your 67°C shot shows at idle, when you use the drives associated with that chipset, it gets hotter. Totally normal. If it bothers you, you can move the Sata drive. Your drives should be in 0/1 anyways which are Intel Sata3 6Gb, the other Sata ports being the ASmedia.

Seriously doubtful your sata/usb controller chipsets have thermistors capable of reporting temps.

What I'd like to know is where these programs are taking these temps. I'm running HWMonitor, and TMPIN5 and TMPIN6 are both reading over 110ºC in idle state (the other 4 are normal, whatever that is). I'm okay with ignoring the data, but how is the program recovering these temps? Are there thermistors all over the new MOBOs?

Some new mobo's yes. I just looked at a new asus board, and even the website shows 5 or 6 sensors spaced strategically around the board. This will have more to do with asus software than Hwmonitor etc. Old mobo's, lga1155 - 1150 are lucky to have 2 or 3, the general attitude being that of 'you supply airflow case temps will be fine'. But with gamers and temp perfectionists really wanting to 'know' vendors are listening finally. Currently the biggest temp culprits are m.2 SSDs as these don't really have much heat shielding, so sticking a sensor there is a great improvement.

The sensors don't read temps, as such. They read a digital signal. Algorithms in the software take that digital signal and convert it to a temp you can read. However, this signal comes from a specific address. So let's say TmpIn6 is coded to read that signal from fff001 to ffx999. The address of the mosfets might be ffn234, so falls in the right place. But, the digital signal on the mosfets is not a sensor reading, it's something else, the algorithm still figures it is and you get a defacto temp reading of 255°C. Or 110° or -125°. Basically the software is adding 2+2 and the answer you get is 5.
