I just installed an i5 4690k with the CM Hyper 212 Evo Cooler. I'm using the original fan and thermal paste. And I had some high temps compared to my previous build and thought I'd ask about it.

Normally it's around 30-33C idle, that is, when I'm not doing anything. Basically AFK.
But just browsing the web or downloading something over Steam can cause the temps to go up to around 37-45C which I thought was quite high for just downloading something in the background. But even though it's in the background the CPU usage is around 20-40% in Windows 10.

I played BF4 for a while and temps maxed out at 59C. Fan maxed out at 780RPM, normally at 600RMP.

Is this normal behavior? Are these normal temps?

I've ordered new thermal paste, Artic Silver 5 and a new fan, Noctua NF-F12 PWM.

It's normal for haswell temps to fluctuate like this, mine does the same. It's due to the sudden voltage changes and quicker temp readings, apparently. Oh, and a max temp of 59c is pretty good, don't know why you would order a noctua fan. it cost's almost as much as the cooler itself (at least thats the case in Norway). The stock fan is actually really great. And unless you want to do some heavy OCing, in which case I would order a better cooler, you don't need a new fan.

Those temps are nothing to worry much about.

My old 3570k would run 25-27C pretty steady at idle, overclocked to 4.6ghz using a set voltage and a custom liquid cooling loop. Unfortunately I ruined it trying to delid and further decrease temps.

The replacement 3570k I got runs around 40C and fluctuates a lot while idle. and I can only get it to 4.2ghz before the temps get way too high.

My point is, two of the same processors, and way different temps on both using the exact same cooling and in the exact same case in the same conditions. Even set to stock voltage and clocks, this new one runs way hotter than the old ran while overclocked heavily.

Your chip just might run hot. Though, your Noctua cooler and thermal paste you ordered should drop your temps a bit.
