Been looking at the theads and it seems like people are having issues with the temperatures on the i7 7700K

My processor is not currently over clocked.
While my computer is idle (just background processes) the temps will jump around from a base of 30 C (summer heat in house) to 50 or even 60 C.

Is this normal or do I have a bad processor.

Thanks

Spikes even up to the low 70s are perfectly typical of most recent Intel CPUs.

The polling rate on the sensor is catching the CPU when it is under load, even briefly. Your cooling is all about sustained cooling, so the whole CPU can get a lot warmer for a lot longer, which makes the CPU cooler warmer, the warmer it is the better heat exchange it will have with the cooler environment (to a point) You can't expect instant heat transfer from the CPU to the cooler, thus the spikes. If you put your CPU under a heavy load and it sustains an average below 80C, you are still well within spec for the chip. More than that and you need better cooling.

Kabylake/Skylake can ramp up very quickly compared Haswell and previous generations. So it...

30 on idle is normal, 60 on load is normal

the problem people mention is sudden spikes to 90°c or some cores hotter than the other for no reason

in general, intel messed up that cpu, delid the cpu is what most end doing, but this voids warranty

others have returned the cpu

Kabylake/Skylake can ramp up very quickly compared Haswell and previous generations. So it runs up, does the work, and cools back down rapidly.

If you saw sustained high temperatures at idle, that would be concerning.

i7-7700k does run hot, but only because it is essentially Skylake overclocked just that much more. There is a price to be paid for the 4.5Ghz stock boost frequency. And, as usual, Intel has skimped on the thermal compound and its application, so some CPUs will run hot due to that. (Mine did, one core was significantly warmer than the others until I took it apart and re-did the thermal paste)

Even so it perfectly handle short term spikes, I think I saw a 91C once.
