r/overclocking on Reddit: Are Core Temp numbers accurate? Or rather how long should it really take for proper thermal temps? First OC coming up soon.
October 10, 2018 -
(A repost because I was a derp and said HWinfo in the title instead of coretemp)
I'm doing thermal benching at stock so I have a baseline to read from.
I've seen it recommended to use all over the place but then I also see people say to check temps after and hour or two.
This confuses me because within a minute my 8700k sits at 67c max in P95-26.6 and 78c in P95-29.4.
It never gets any hotter. As soon as I stop P95 and I mean in under a second everything drops right down to low 30s.
Is this normal? Do chips really heat and cool that fast?
Do you actually need to run a long time for accurate thermals?
I have a Noctua DH-15 with one fan as a cooler. The dang second fan doesnt fit in my case. Hangs over my x16 slot for my GPU and it wont fit in the X8 slot. Wacks my hard drive bays hahaha.

Yes it does heat and cool that fast. You will want to maybe run it for 5-10 mins or even longer to get a stable temp reading. As the Noctua fan will spin up and also get to an equilibrium state.
Using the latest Prime 29v is higher temps because you are putting AVX load on the system. V26 Prime doesn’t give AVX loading.

Core temp completely stops recording temps once my i7 is at 100% load. Realtemp counts it correctly under full stress.

May 8, 2008 - Factory Calibration affects the accuracy of Tjunction, or Core temperatures. (C) Tcase and Tjunction are both acquired from Thermal Diodes. Tcase and Tjunction analog to digital (A to D) conversions are executed by separate devices in different locations. BIOS Calibrations from motherboard manufacturers, Factory Calibrations from Intel, and popular temperature utilities are frequently inaccurate. I hope this clears up any misconceptions. Comp ...

August 9, 2012 - I looked in BIOS and it said core temp was same as HM, 30c-31c with each core around 15c-17c. Now, Ive had the machine on all day. Played Diablo 3, Battlefield 3, and burned 3 DVDs. Plus played 10-15 rounds of MWO:Beta. Right now at this moment HM is reporting MB CPU at 30c, and indiviual cores at 13c. Edited by Quinn Allard, 09 August 2012 - 09:31 PM. ...

November 28, 2007 - It is very accurate. Most utilities that come with the motherboard read the CPU SOCKET temp (that little 1/2" square space at the bottom of the CPU socket) and aren't accurate. The problem with Intel TAT is in it's coding. That program DOES read from the digital temp probe, just like Core Temp.

Hey Guys,
Finally have my new PC up and running after beefing up the PSU to a Corsair rm850x 2018 White Edition. Even ran the new Call of Duty for a few hours.
I think HWMonitor is bugged though as it shows a package temp 20 to 30c below what it shows for Core Temps and at one point it showed max individual Core Temps in the mid to high 80s but Real Temp & CoreTemp stayed in the 40s to low 50s for all cores.
I'm running an Intel i7-9700k which my Aorus Pro Wifi stock OCs to 4.6ghz at 1.2V with Boost of 4.9ghz. I rolled back my 5.0ghz OC before I installed the new PSU and didnt change it back while I test ran things tonight. But I did have it at 5.0ghz 1.35V at 69c in HWMonitor 2 days ago stress testing at 100% CPU load.
While I was playing Call of Duty I noticed HWMonitor was showing a package temp in the 50s but each Core was showing around 85c. Real Temp and CoreTemp I pulled up to see what was going on but they showed idle temps in the upper 20s and 30s and temps in the game were in the 40s and low 50s.
I have a Corsair h100i Platinum AIO cooler PLUS 6 QL120 Fans that were all set to EXTREME setting while gaming which basically keeps all the fans up around 1500 & 1600 rpm and the pump was set to the highest setting all the time. The case has plenty of air space and I have an extra fan on the next desk blowing towards my PCs as well as my room fan running on the ceiling plus our house air is set to 68f degrees but the house is obviously cool with the weather.
So I'm not sure why HWMonitor is showing a 20 to 30c higher temp for each core than the other programs.
Is HWMonitor bugged? The package temp seems closer to matching the other programs and obviously wouldnt be showing a package temp well below the core temp by such a large margin.
Am I safe using Core and Real Temp or is HWMonitor still everyone's go to?
Thanks
-DJ
I would suggest HWinfo https://www.hwinfo.com/

... a few threads I read said even most BIOS dont report proper numbers these days ...
What you read is inaccurate and obviously wasn't explained in any detail.
CPU temperature in BIOS actually shows the hottest Core. Also, CPU temperature is higher in BIOS than in Windows at minimum idle, because BIOS boots the processor without power saving features and at a higher Core voltage to ensure that it will initialize under any conditions.
Keep in mind that like the term "full load", the term "idle" is used very loosely, which most users interpret differently because they've never seen the definition. Moreover, when attempting to compare temperatures, users often don't mention ambient temperature. So "idle" typically becomes a confusing comparison of apples to oranges thermal fruit salad in a blender.
The definition of "idle" is minimum software activity at 1% CPU Utilization in Windows Task Manager. Idle does not mean a light workload with multiple foreground and unnecessary background tasks with "tray trash" running at 5 or 10% CPU Utilization ... "idle" means exactly that; idle. No screen saver or email or dropbox or streaming ... off line, hands off, undisturbed idle.
If your rig is at 1% minimum idle in Windows, the temperature will be lower than BIOS. If idle is instead at some undefined elevated level of activity in Windows, then the temperature will be higher than BIOS. If you want to make sense of it, then it's always necessary to define the parameters, and identify and account for the variables so results are consistent and repeatable.
