Cpu package temperature hotter than individual cores?

[jasonkang93]

Hi, so ive been running prime 95 and ive been noticing that (through hwmonitor) that my package temperature is always 8 degress celcius higher than the hottest core. All four cores are actually consistent (+/-3) but the package temperature is what has me worrying. Some people have suggested deliding but i would really hate to void my warranty. Could my problem be that ive applied the thermal paste wrong?(only hesitant because im almost all out of my thermal paste)
Thanks for any input!

Rig specs? More info is better than less.

You didn't mention what temps you are actually seeing, but Ivies run hotter than sandies or haswell. Try a couple of different monitor programs - hardware info, speedfan, etc. It's not unusual for there to be some variance between reported temps in the monitor programs, and it's not unusual for package temps to vary from core temps. It all depends on where the sensor(s) are placed on the die/package. My 2500k runs about 3* higher in pkg than the cores, but never exceeds about 60* with the Hyper 212 cooler.

You may also want to check and/or redo the TIM, especially with an Ivy. Any bare areas, bubbles, etc will show up in higher temps. Make sure your H60 is seated firmly, and make sure your airflow is good, especially around the gpu's - sli 670's are gonna pump the hot and they could easily influence your cpu.

In prime 95 all my cores are just around 70 degrees while the package is at 75, however in intel burn test all my cores are around 80 while the package is at 88 so i quickly turned that off. also, i have very good airflow on my case (got 2 fans on the side and 2 on top for exhaust and two infront of drive cage) which applying method for thermal solution do you recommend? ive tried pea sized but when i open it up it always fail to cover all sides so currently i did a small line and set the pump on top and removed it again to fill in little spots
EDIT: do you recommend any temp monitoring programs that show cpu package temperatures? i remember coretemp only showed individual core temperatures and that program in my situation wont be helpful

I personally like hardware monitor for temp monitoring - it will cover all the bases.

As far as TIM goes, I'm old school - I use a credit card to spread a very thin layer over the entire lid. I also fill gaps on my older Hyper 212. Every time I try the "pea/rice", "one line", "three line" I get worse results than hand spreading. I can't say I'm up on any differences you might encounter using the closed loop, but I've always been happy with my air cooling.

You temps on P95 are in line for an Ivy, but do seem a little high on Intel, although Intel stresses the cpu harder.

On your airflow - you need more intake than exhaust - if you can't get the air in (which you can't since you are creating a negative pressure with no opportunity to fill), you can't get the heat out. Use positive pressure (more intake) to force hot air out, aided by the exhaust.

ooops sorry i meant i have only 2 on top for exhaust and 4 for intake (side and front)
and ill try your method! it seems the only plausible explanation for really high temps in intel burn test is because of bad appliance of thermal paste. When you do your finger or card spread method how to u start off? just a random blob in the middle then spread?

 

[markwp]

Yep - rice grain in the middle - I've used credit cards, or my finger wrapped in a baggie. The secret is to get a thin coat on the entire surface - that way you don't have to hope your pea/line/dot will spread correctly.

Thanks for the update on the fans - you should be fine - just be sure you have really good flow over the gpus.

Thank you so much for your help! you saved me a warranty 😉 and put a heavy load off my heart

Last thought - make sure your H60 pump is working correctly. That's why I use air - I can see when the fan dies.

Good luck!!
