In seconds no, over a couple minutes yes. Does this happen when you enter a level after a cut scene or when you first load a area? It could just be a spike like for example if you watch task manager and right when you first open a program your cpu usage spikes.

With newer smaller high performance Intel cpus, the temps do go up very quickly under load. (they also come down quickly). Which cpu/cooler combo do you have? Overclocking/extra voltage?

Which cpu do you have - the old core 2 chips had a lot of surface area and a better way to get heat out of the cpu - solder as opposed to thermal compound.. Because there was more mass they did not fluctuate in temp very much - everything was more gradual. My Devil's Canyon I7-4790K will get up to beyond 80C when I stress it with Intel's XTU:

When I'm done my temps go back down very fast.

I say you have quite a bit of room for OCing available. You are at 4.2Ghz with 1 core and 4.0GHz with the remaining 3 cores. I would think 4.4GHz for all cores would be quite easy to achieve and possibly a little higher. I looked at the OC guides at

I have one more question I noticed while gaming although I have around 40 % Cpu usage I have sometimes temp spikes to 75 C (once for second everyminute or so and comes back to around 50-60C ), my mobo is also getting around 60 C - 65C is it ok?
Btw is it normal that sometimes one core is hotter then others? Not the same always but for example i have sometimes single temp spike in first core, then forth, then third and so on. What do you think? Im sorry for that many questions ;d

You have an intel cpu. Those have on-core temp sensors so yes, as cores see almost instantaneous usage, you'll see very quick temp changes. This is perfectly normal behavior.
It's also perfectly normal to see @5° difference in cores either direction. This is due to differences in Silicon, differences in TIM thickness, differences in cooler paste thickness, tightness of cpu cooler etc. This would be if all cores ran exactly the same material at exactly the same usage.
On top of that, Windows and apps assign different cores different chores, so today easily see a primary core under 100% usage with a secondary at 50% and 3rd/4th cores only using 15%. This will definitely put the primary core at high temps, over 70°, secondary at 50+° and 3rd/4th cores at 35°.
Again, normal behavior.
ITU isn't exactly the best stress tester as it uses a variable on cpu load, which means usage changes. This is true of most of those testers. The best to use is prime95 v26.6 (not the newer versions) which under small fft will give a 100% usage across all 4 cores in a constant rate.

I have a 3570k and a 3770k. Both sit at 31-32 idle but occasionally jump to 35-45 depending on exactly what Windows decides to run in the background. Antivirus, backups, Web updates, all those and more will run on a core in the background, causing temps to momentarily raise. Perfectly normal windows idle behavior.
you guys were really helpful.I have one more question. It might a bit out of topic but look. http://i.imgur.com/CQKVT65.png
Thouse are mine mobo temps, aren't they badly high? Whats funny they look exactly the same as the intels cpu measurement. What do you think? Its during stress test (memory test?). Idle it is around 25 C.

That's the mobo temp? That's the area around the socket, the voltage regulatory circuitry including the old Northbridge chipset which now controls the pcie lanes etc. During stress tests, either memory or cpu or even gpu, that area will be doing considerably more work, so temps will go up. At idle, you aren't doing much work at all so temps will be lower. Package temp is the entire cpu temp, so it'll usually run somewhere around the same temp as your highest core.

Hwmonitor is a pretty good piece of software, but it does have limits. It'll not encompass every single motherboard as there are always changes in design, addressing etc so exactly what that temp is is anyone's guess. It could be the Northbridge chipset, VRM's, or even a now defunct Southbridge address reading the temp on a sata port. On my pc I've got Hwmonitor that reads 256°C for 1 temp and -120°C for another. So for most of what you are looking at you can take with a grain of salt. As long as cores/package etc are all within acceptable ranges, you'll be fine.
