How do I change CPU temp in windows 7?

Asus Z7s ws motherboard
September 28, 2010 at 18:56:58
Specs: Windows 7, X9775/16
My BIOS shows correct temperature around 47C but any software in windows shows only 17C.
It's impossible that my CPU's temperatures gets much colder than air temp (26C) after booting and running OS...
Didn't found nothing about it on the web.


Using:
ASUS Z7S WS
2x INTEL XEON X9775

HWINFO32 http://www.hwinfo.com is very good software and reliable

It has been helpfull somehow! tks Great software!
But I still have diferent readings between sensors and my cooling manegment software. Actually any software that reads cpus temps shows bugged readings. Even Asus probe catches wrong readings trough windows.
With HWinfo I could get redings from Windounds sensors, one tree shows CPUs 1 n 2 with arroun 45C, reasonable. Another shows 110C, possible but unreliable since I've got 24C readings on the coolant.
The CPU Digital sensor shows temps from 8C to 20C to the eight cores, unreliable, it couldn't be colder than the coolant.

What I need is to make windows or any other software to get the redings from sensors witch I believe now are acurate. (not sure)

How I do that? Tks again!

i doubt it is a problem with your windows, it maybe that your sensors are not very good, that your bios sensor is misreading..are you sure all the sensors are reading C and not also fahrenheit?
your cooling management maybe using different sensors, in fact probably..it also depends if your coolant is only hitting the cpu, or going to the gpu and other cooling points, i assune you are using some sort of liquid cooling..the cpu can be cooler than the coolant, as the cores give their heat to the cooling block and the coolant take the heat from the cooling block, if the cpu is not getting warm or doing and work, it can be 8degrees because any heat is dissipated into the cooling block, but the coolant is been cooled by the ambient air through the radiator, so will run at a temp slightly less than the ambient as the metal of the radiator will also dissipate some heat from the coolant and if the coolant is not getting warm..
you have to decide which temps you want to use as a true indicator and work with them..ignore all other readings.

i hate computers!
but cant help myself....

ok I understad and agree with you.
But here's what: I'm reading 24C~26C in the coolest point of the liquid cooling tubing circuit, right after the radiator. It means liquid is traveling from this point at 25C straight to CPU0 and to CPU1 right after, then splited between 3 chipsets.
That only would bring CPUS temp to round 25C even in hipotetic full idle. Its heat change, even with dissipation without heat production.

The system has a high flow with two CoolIt Boreas Active TEC Radiators beiing capable of bringing down the coolant temp to 19C~20C, but I'm using it only at 40% power because of noise and water condensation (I live in brazil, higher humidity and hot dew point here).

When I turn on the machine and go into BIOS it shows reasonable temps for a cooling device as mine, shows RAMs (not liquid cooled) at 58C, and CPUs arround 36C as Motherboad Chipsets.
When in Windows the manegment sofware seams to read 30C less tha the BIOS. I've tried other CPU temp reading software but all with the same bad reading.

And I'm quite puzzled cause I deal with computer hardware since 6yo, learned from my father in the 80's assembling x86s and Novel networks with 10 Base-T devices. (quite a novel)
I'm up since BBSs and MMX Videotexting.
More than 25 years assembling high-end for consumer workstations. I'm also Civil Engineer and Architect.
Never saw a issue like that...
Searched all corners of the web but all people have is trouble with "overtemp" missreadings.
I Have:
-re-burned BIOS;
-re-instaled Win OS from zero;
-re-mounted CPUs;
-changed PSUs (2x1000W now)
-made some praing for St. Expedito (brazilian saint of the impossible causes);

Realy think the only thing is if someone knows how to change windows reference for temp sensors.

I have found that most sensing utilities require some tweaking. One thing is the identification of the sensor is sometimes in question and you must choose from a list or even supply it.

Then there are offsets in most utilities to adjust the readings to reflect the BIOS readings, which of course are considered the most accurate. I have seen to sensors switch the two main readings and assign system temp to CPU temp.

If you have simply downloaded a sensing utility and installed it then try searching for updates.

Consider all the above to just be comments and may be of no use.
