Question New intel I7-14700K build - temp. difference, repaste or not?

[BenjaminP]

Hello everyone,

I have noticed a "big" difference between the max temp in my newly assembled cpu performance core's , this happens while the system is running on standby.

6 P-cores are between 36°c and 40°c
1 P-core at 45°c
1 P-core went up to 58°c

Should i worry about the 22 degrees difference in temps, and try repasting the cpu or is this normal on 14th gen ?

System spec's :
CPU - I7-14700k
Cooling - Artic Liquid II 360
RAM - 64GB Corsair Vengeance DDR5 6400
MB - MSIPRO790A Wifi
GPU - RTX 2070
PSU - RM1000e
SSD - M.2 Samsung 980 1tb
Windows 11

Thank you,

how hot is it while gaming?

Depends on what the cores are doing, if only 1 is active, it might sit at 58C while the others are lower.

Run a stress test and see how it does core to core then. Sitting on the desktop is a measure of basically nothing.

The lowest at 56°C highest at 69 °C

I will try to run a stress test to test

Here are the results after running prime95 for some time

86°C on lowest 100°C on highest with 1 core almost always hitting 100°c

That might be worth looking into. If a re-mount doesn't do it, that may be cause for an RMA, but that would be for Intel to judge.

Haven't kept up with recent versions of Prime 95, but the last I heard it stressed a CPU well beyond what users are likely to experience in actual day to day use.

But that might not pacify you if you are HIGHLY concerned.

There are background tasks that may have one or 2 cores active, so the cpu is seldom doing nothing.
Plus, with how turbo boost works, sleeping cores practically 'jump' out of bed regardless of the level of the task, and go right back to sleep.

Prime95's settings matter, so this doesn't really tell us anything, and P or E cores weren't specified.

I have this cpu and I am not sure I would even look at core temps unless I was investigating an abnormal package temp situation confirmed by a couple apps. If you aren’t doing stability tests I wouldn’t be doing stress tests either. I don’t do anything more than World of Warcraft at the moment but the highest temp I‘ve had since I bought it was 86 degrees in CPUz and Intel XTU benches. At idle the package temp flips between 26 and 36 degrees.

Prime 95 was tested using Small FFTs (L1/L2/L3 caches, max power/heat/Cpu stress) with all 3 avx options disabled

After about 5 min the cpu package hit 100°C -

1 Pcore 100°C @ 5.488MHz max
1 Pcore 99°C @ 5.586MHz
The rest was between 86 and 94°C @ 5487/5488 MHz max

E-Cores package was 88°C and individual cores ranging from 83 to 90°C all @ 4.290MHz max

Tell me if you need any more specifications,

Im mostly wondering if i did a bad paste job, (i will repaste later today and i will post if anything improves/changes) if im experiencing warping or just have bad luck with the cpu and should try to RMA it.

No, that's good. It's what I wanted to see.

So i repasted the cpu i noticed that the paste seemed to be slightly thicker on 1 side of the cpu.
Then i ran Prime 95 again and got similar/slightly better? results

After about 5 min's the cpu package hit 100°C

1 Pcore 99°C @ 5.586MHz
1 Pcore 99°C°C @ 5.487MHz max
The rest was between 85 and 94°C @ 5487 MHz max (-1°C on lowest and highest core)

E-Cores package was 88°C and individual cores ranging from 83 to 88°C all @ 4.290MHz max (-2°C on max temp)
