Need some help with temperatures.

[Nilangan]

I have a Core i7 2600K (not overclocked, hyperthreading is on) with Intel DH67BL mobo,Gtx 1060 3GB EVGA, 2 sticks of DDR3 2GB RAM, and 1 stick of DDR3 4GB ram 1333Mhz. I have only started looking at temperatures few days back. I have few questions, on open hardware monitor I can see temperature 3 going around 80 degrees, I am just seeing this today, I dont think i noticed this before. Also I didnt notice this on other tools. CPU temps are around 45-55 degrees while using chrome. Screenshots from 3 tools http://imgur.com/a/vk5mM . Also I noticed that temperatures shoot to 70C after playing syndicate (just opened the tool after closing the game. Didnt check while in game). Is this safe? I see the limit for my cpu is 72 degrees in google.

In BIOS, I can see the CPU temp shoot up from 60 degrees to 80-85 and on default it is set to throw an alert at 88 degrees. Should I change this to 72 degrees? The CPU is 6 years old. Also if the limit is indeed 72 C , is it safe to game at that temperature? I see no throttling.
EDIT- I am seeing this same temperature 2 from open hardware monitor as SYSTIN on HWinfo64 around 87-90 degrees now. But on Hwmonitor I can see the temperature around 41 degrees. Should I be worried?

I have a Core i7 2600K ... I see the limit for my cpu is 72 degrees ...

Nilangan,

Unfortunately, it's not quite that simple. 72°C refers to Intel's "Tcase" Thermal Specification, which is a misleading specification, because Tcase is not Core temperature ... Core temperature is considerably higher. Intel's Thermal Specification for "Throttle" temperature is "Tj Max" which is a Core temperature of 98°C for your i7 2600K.

Here's the operating range for Core temperature:

Core temperatures above 85°C aren't recommended.

Core temperatures increase and decrease with Ambient temperature.

Read this Guide, but pay close attention to the explanation concerning Tcase in Section 7: Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

Check while gaming to confirm temps. HWmonitor is not very reliable. I have had some of CPU's report 170c with HWmonitor

Your CPU can safely operate at 80-90c although it is quite high. The maximum for Intel CPU's is 105c (at which point they will be damaged).

Changing thermal paste and upgrading to a better cooler or more airflow could help get the temps lower.

Respectfully, that doesn't quite work as a blanket statement. Click on my link above and read that Guide so you can get yourself up to speed on this topic. It's always more helpful when you provide other Forum Members with accurate information.

Throttle Temperature

Also called "Tj Max" (Temperature Junction Maximum), this is the Thermal Specification that defines the Core temperature limit at which the processor will Throttle (reduce Core speed) to protect against thermal damage. Throttle temperatures are shown below for several popular Quad Core processors, including Thermal Design Power (TDP) and idle Power, which are expressed in Watts (W).

Core

7th Generation 14 nanometer i7 7700K / i5 7600K (TDP 91W / Idle 2W),
6th Generation 14 nanometer i7 6700K / i5 6600K (TDP 91W / Idle 2W):
Tj Max (Throttle temperature) = 100°C

5th Generation 14 nanometer i7 5775C / i5 5675C (TDP 65W / Idle 2W):
Tj Max (Throttle temperature) = 96°C

4th Generation 22 nanometer i7 4790K / i5 4690K (TDP 88W / Idle 2W),
4th Generation 22 nanometer i7 4770K / i5 4670K (TDP 84W / Idle 2W):
Tj Max (Throttle temperature) = 100°C

Legacy Core

3rd Generation 22 nanometer i7 3770K / i5 3570K (TDP 77W / Idle 4W):
Tj Max (Throttle temperature) = 105°C

2nd Generation 32 nanometer i7 2600K / i5 2500K (TDP 95W / Idle 8W):
Tj Max (Throttle temperature) = 98°C

1st Generation 45 nanometer i7 860 / i5 750 (TDP 95W / Idle 12W),
1st Generation 45 nanometer i7 920 D0 (TDP 130W / Idle 12W):
Tj Max (Throttle temperature) = 100°C

Core 2 45 nanometer Q9550 E0 (TDP 95W / Idle 16W),
Core 2 65 nanometer Q6600 G0 (TDP 95W / Idle 24W):
Tj Max (Throttle temperature) = 100°C

]Tj Max specifications may vary with TDP. Certain low TDP processors Throttle below 85°C (185°F) but many 3rd Generation processors Throttle at 105°C (221°F). Low TDP Core i 6th and 7th Generation CPU's have Configurable TDP (cTDP) and Scenario Design Power (SDP) which can trigger Throttling below Tj Max. Although most processors Throttle at 100°C (212°F), it’s not advisable to run your CPU near the thermal limit, just as you wouldn't run a vehicle with the temperature gauge pegged in the red "hot" zone.

If your hottest Core is near it's specified Tj Max Throttle temperature, then your CPU is already too hot. The consensus among highly experienced and well informed system builders and overclockers, is that cooler is better for ultimate stability, performance and longevity. Experts agree it's prudent to observe a reasonable thermal margin below Tj Max. So regardless of environmental conditions, hardware configurations, workloads or any other variables, Core temperatures above 85°C aren't recommended.

That is quite high but it isn't anything to panic about just yet.

That CPU will automatically throttle when internal temperatures get too high - the 72 degrees is the external temperature max. The internal max is a bit over 90 degrees.

I wouldn't set the alert temperature that far down - those defaults follow intels published guidelines.
Maybe just set the alert a bit lower to give you a little headroom, like 80 or so degrees.
I have seen a few forums where overclockers run that cpu at 80 degrees and say you should not go over 82 during heavy use.

It might also help to try improve ventilation, blow any dust out the fans, see if they all still work nicely.

 

[CompuTronix]

... The internal max is a bit over 90 degrees ...

Please read my posts above. Intel's Thermal Specification for Tj Max (Throttle temperature) for the i7 2600K is 98°C.

Woah guys I cant thank you enough. Wasnt expecting so many people to reply this fast. So in short CPU temperature around 70 degree while gaming is nothing to worry about? Btw none of you replied to my second question. The temperature 2 (on open hardware monitor) and SYSTIN on HWinfo go to 80-90 degree C . Just while browsing chrome. Is it safe?

PS- Thanks Jason too for your reply. I forgot to quote ur post. Sorry

Thanks CT

I read through your excellent educational post! Great info. My takeaway from it is that as a general rule of thumb Core temps should be kept under 85c? Would you recommend that as good default advice for Forum Members?

 

[CompuTronix]

Nilangan,

It would be nice if you would tell us what your ambient temperature is, as well as what cooler you're running.

Temperature monitoring utilities often don't correctly identify and assign values to sensors, so it's not uncommon to see bogus values on sensors with ambiguous names, such as "Temperature 2"or "SYSTIN" which read values such as -127°C.

You need to focus on Core temperatures during heavy loads, which are most important. Anything under 85°C is OK, but personally, Core temperatures that begin with "8" make me uncomfortable.

... as a general rule of thumb Core temps should be kept under 85c? Would you recommend that as good default advice for Forum Members?

Actually, I've already said so in the Intel Temperature Guide. It's a Sticky near the top of the CPUs Forum in which this Thread is located. The Guide has been there for several years, but most Members don't notice it since they don't bother to look at the Stickies. I keep it updated, so the information in it is current. You might want to give it a read - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

Room temperature should be around 30 degrees C. and I am using the stock fan for the CPU and a fan in the case. The rig is 6 years old. I dont game much. Maybe one hour in a day sometimes. So I shouldnt worry about the "Temperature 2"or "SYSTIN" ? anyway to know if the value is correct? my board is DH67BL. Even if the value was correct, is it safe? HWmonitor shows SYSTIN to be around 50 degrees but the rest show 80-90

 

[CompuTronix]

30°C (86°F) ambient temperature is quite a toasty environment for a PC. Standard or "normal" ambient is 22°C or 72°F, so you're 8°C above normal, which also runs your Core temperatures 8°C hotter than normal.

I recommend that you replace Intel's woefully inadequate stock cooler with an inexpensive aftermarket cooler such as the excellent Cryorig H7 - https://www.newegg.com/Product/Product.aspx?Item=9SIA4UF2DZ6565&cm_re=Cryorig_h7-_-13C-000U-00005-_-Product

Concerning "Temperature 2"or "SYSTIN", the monitoring utility "Hardware Info" is typically better than most other utilities at correctly identifying sensors - https://www.hwinfo.com/download.php

Nevertheless, I wouldn't lose any sleep over it. As I've pointed out, your biggest concern is Core temperatures, so my best recommendation is to replace the stock cooler as soon as possible. The 2600K is still a great processor. Sandy Bridge was the last Generation to have a soldered Integrated Heat Spreader, so unlike 3rd Generation and newer, they're thermally well behaved.

With decent cooling, most will overclock from 4.6 to 4.8, with a few even reaching 5.0 GHz. Replacing the stock cooler will give you the thermal headroom to overclock, if you wish to do so at some point in the future. For the present, a decent cooler will at least seriously drop your Core temperatures to respectable values.

SYSTIN on HWinfo is 80-90 degree as I mentioned earlier. Is thik okay or will I need to do something about it. And abou the core temperature, they are generally around 45-50 degrees and go to 60-70 degree while CPU intensive gaming, it's still okay right?

 

[CompuTronix]

I was still editing when you quoted me, so please read my post again.

 

[Nilangan]

I was still editing when you quoted me, so please read my post again.

thanks again,. my question still remains the same as I cant change the cooler atm. I spent all the money in upgrading GPU RAM. Also I dont want to overclock yet, my current mobo doesnt support it anyways. The temperature 40-50 degree around normal usage and 60-70 while gaming will not be an issue for now? And will I need to do something about high SYSTN?

 

[CompuTronix]

You've tried Hardware Monitor, Open Hardware Monitor, SpeedFan and Hardware Info ... none of which have accurately identified "Temperature 2"or "SYSTIN".

If those values are consistently high and don't appear to correspond to changes in Core temperatures ... OR ... if they fluctuate wildly but again don't appear to correspond to changes in Core temperature, then it's likely the utilities are sampling unassigned or open sensor inputs.

If, on the other hand, Temperature 2 or SYSTIN change with Core temperature, then it could be the thermal sensor for the CPU's Integrated Graphics Processor Unit (IGPU) ... OR ... the motherboard's voltage regulators.

Either way, it's likely that the values you're seeing are uncalibrated or otherwise inaccurate, since the hottest sensors are always those which are located within the Cores.

That makes sense. Thanks. You're the best. Only HWmonitor shows the stats at around 45-50 SYSTIN. Maybe thats correct.

 

[CompuTronix]

Do you have a temperature which is clearly identified as your Graphics card? I didn't see any GPU on your screenshots.

http://imgur.com/Kk73Tjc here. the GPU temp is low, even the fans are not moving so I thought i didnt need to mention it.

 

[CompuTronix]

Thanks. We can rule that out. The 1060 is a nice card.

So it's back to Hardware Monitor that's most likely giving you a plausible sensor value, which could also be the motherboard's Platform Controller Hub (PCH) chipset.

So.. what do you say? Will i need to do anything about it?

 

[Nilangan]

BTW an update: I kept the pc turned off for two hours and after turning it back on I see temperature 2 at 45 degrees. I think I remember seeing high temperature at temperature 2 sometime in the past. Any idea what may cause the spike nd anything I need to do about it?

 

[CompuTronix]

Nilangan,

If your "spike" or temperature anomaly is due to, for example, a faulty or intermittent PCH thermal sensor, then there's nothing you can do about it other than replace the motherboard; not a practical solution for hardware that's otherwise functioning properly, and 45 to 50°C is nothing to worry about.

On the other hand, if your "spike" could be more accurately characterized as a gradual warming up that corresponds to workload, then you can improve cable management and install additional case fans to remove excess heat from your case, which will in turn reduce temperatures across all components.

If your temperatures drop more than a degree or two when you remove the case covers, then it's a sure indication that your case has poor airflow. Looking at your motherboard configuration, and depending on which EVGA GTX 1060 card you have, hot exhaust may be blowing on the PCH heatsinc during gaming.

Your motherboard's PCH heatsinc is positioned close to the PCIE x16 slot. The single fan 6.5" 1060 has longitudinal cooling fins that exhaust heat from the case. EVGA's dual fan 1060 has laterals cooling fins that exhaust heat onto the motherboard and PCH heatsinc, which would cause high PCH temperature.

Section 14 in the Guide is all about "Improving Temperatures". You might want to check it out.

Sorry to bother you again. I wasnt gaming. Just using chrome. I have the single fan EVGA 1060 and the fan wasnt spinning. I continued to use the pc for four more hours and the temperature 2 remained at around 70-80 degrees, I restarted and saw same temperature. I kept it turned off for 2 hours and the temperature decreased. The day before yesterday I gamed but didnt see this spike. As far as I remember I think I periodically see this spike and it stays before I cool it. I started my pc today few mins back and the temperature 2 is around 35 degrees. Will see if it rises after I keep using the PC.
