i7 4790K temperature fluctuations

[Xer0x1337]

Folks,

I've bought the i7 4790k (stock voltage, no o/c) processor recently. All seems fine, but the thing that worries me are the fluctuations in temperature. In idle state the temperature changes every second with 1/2 degrees celsius around 30 degrees celsius. Under full load it's steadily around 60 degrees celsius, which seems to be OK. The cooler I'm using is the Scythe Mugen 4.

Do I need to worry about these fluctuations? Will it degrade my CPU over time? Is it likely that the fluctuations are caused be faulty montage of the cooler or thermal paste?

Thank you so much!

A CPU is only going to sit at true idle if you intentionally shutdown any and every process that might require CPU input or management. Background processes are going to be constantly making low-level demands on the CPU, which can explain those small fluctuations.

Xer0x1337,

Temperature fluctuations are completely normal. As volcanoscout described, the loads on your processor cores are constantly changing, and temperatures respond instantly to even the slightest changes in load.

Just right-click on your taskbar, click on "Start Task Manager", click on the "Performance" tab, then watch "CPU Usage History" while also observing the core temperatures on whatever temperature utility you're using. After awhile, it'll all start to make sense when you see how core temperatures exactly and instantly correspond to changes in load.

I'm so sorry for my late reply!

Alright then, I guess it's fine then!

Thanks!
