Question All temps are good except for "TMPIN2" - 81º C (177ºF) - - - Why ?

[Motaro47]

Hello all. Was checking temps via HWMonitor randomly in one of my slightly older rigs tonight and noticed this temp was 177ºF/81ºC. Every other temp in the list seems fine, besides tihs. I looked through full version OF CPUID and could not find this temp, even while searching the printout file, nor could I find it in Everest. I assume ITE87 is a sensor chip on the MOBO? Perhaps it is reading inaccurately, and some part of the chip has gone bad? 177º sounds astronomical for my room in the cold New England winter when desktop is on ground floor where coldest air is and every other temp reading else is 140s or lower.

What/where is this temp, why is it so high, and how to bring down? Thank you.

(temp is under the ITE IT87 tree under the first 'Temperatures", leading to TMPINS2: 177º F/81º C )

Update your post to include full system hardware specs and OS information.

Include PSU, disk drive(s), and case.

EVEREST Ultimate Quick Report

*Was not sure if you wanted me to reply, or to EDIT my original post.
*Also was not sure if you wanted simple manual type-out of basic specs, or full CPU-Z printout, so used Everest to print out something that is not 20 pages long which has all info required, I hope, without being too lengthy.

Case is simply a 15+ yr old white generic case that I re-used to build this PC several years ago, and has 1 large fan, in addition to CPU fan which is an upgraded "Dark Knight" heatsink+fan. In addition, there is PSU fan, and GFX card fan - GFX card I replaced only about 6 months ago since the prior one died on me, although it looked fine, visually. Not sure what killed it or how. Current card is a GeForce 1650 Super. CPU is AMD Phenom Black Edition Quad Core 3.2 GHZ "Deneb". 16gb of ram - 4 in each bay. The rest of detailed info is in attachde .txt file.

Long Report (CPU-Z TXT Report)

*IMPORTANT* I left the PC off all night (~10 hours) and woke up to a vert cold room, approx 65ºF - AC cord unplugged from pc - so all of PC must have been ~65ºF. I turned it on, and sure enough, by the time it reached Windows(80-90 seconds), all CPU cores were only 106ºF, and nothing else was above that - not any of the 4 storage drives, not GFX card, not TMPIN0 or TMPIN1; nothing except that TMPIN2 #2 sensor, which was reading 172ºF.

I was a little surprised that in, max, 90 seconds, the CPU core temps went up from room temp 65ºF to 106ºF, though. I'm not a hardware engineer, but a 40º jump in 90 seconds seemed like a fast spike -- maybe normal? Maybe it needs removal and new thermal paste, or maybe it's going...or maybe it's normal, lol.

Thanks so much, please ask for any other info required.

have you looked at that sensor before? Or is this first time?

Not all sensors on boards report right temps. I had an old Asus motherboard that used to show negative temperatures. rest of the temps seem fairly normal... just ignore it.

No I have never looked at that sensor before, either physically/visually or otherwise; I don't know why, it just eluded me - I built this pc but TBH I have no idea what that 'row' of 3 sensors correlates to. The others listed, of course I know - it says it in programs like Everest or CPU-Z - but how is one to know what apparatus the TMPIN0/TMPIN1/TMPIN2 sensors refer to?

Ok, thank you very much for this info, I truly appreciate it; sets my mind at ease. Thank you Colif

TMPIN0 = Motherboard
TMPIN1 = CPU
TMPIN2 = Northbridge

HWMonitor.. what are the TMPIN#?

www.overclock.net

motherboard - Gigabyte GA-MA770T-UD3P
So the Northbridge is a chip marked AMD 770

Not a lot you can do since its got a heatsink on it already - https://www.guru3d.com/review/gigabyte-ga-ma770t-ud3p-motherboard-review/
Make sure its not clogged up with dust is one thing you can do.

its been integrated into the CPU on newer boards. I mistakenly thought it was refering to the chip marked SB 710 but thats the Southbridge.

looking at this, sensor is buggy as people get all sorts of recordings from it - https://forums.guru3d.com/threads/gigabyte-ga-ma770-ud3-northbridge-heat.323463/

Thank you for that info, and the rest; you went above and beyond with my question, appreciate it greatly.

1) Not that I'd want to, but, is it possible to remove that heatsink over the Northbridge?
2) I have an old point-and-click Duratrax temp reader I used/use with my R/C Cars, for reading and maintaining temps on the aluminum-head ABC nitro engines. Since so many of these metal computer parts also seem to be alum, like this heatsink on Northbridge, I was able to get a clear point-n-click @ it, and I took the mean idle temp over 10 readings to get around 110ºF.

From what I've read, diode vs heatsink temp difference is usually about ~10,º so actual temps are probably ok/safe, with sensor very likely being completely faulty?
