i just got a new mainboard(Asus Maximus VIII Hero), cpu(i7 6700K) and a new cpu-cooler the Corsair Hydro H100i v2. I installed everything, also the Corsair Link 4 driver.
After i started it the driver, i was shocked by the strange numbers. Every Core of my cpu was at a different temperature and it changes so rapidly. For example 30 degree celcius to 50 and back. can somebody help me?
I might plugged the temperature cable wrong while installing, but i dont think thats the issue

Never listen to one program. Apparently Corsair may be too sensitive for one reason or another. I don't know why it would offer that info. One reason could be because of many background programs.When you say driver I think of drivers necessary for GFX cards, chipset and other hardware. Temperature variations are complete normal. You seem to be sorta new to temperature monitors which suggests you might also be new to your task manager and services. You can open your task manager and click on CPU. You will see what is using your CPU which would explaing why the temperature rose and fell. When you first build a computer Windows will be busy for the first few hours to days. It needs to Index a lot of information. There is also superfetch and prefetch to consider which improve your file explorer experience as time goes on(when using an HDD). Windows Defender may need to update it's definition list or it may be performing a security scan. Many reason why those temperature fluctuations happened. Windows also downlclocks according to the PC's needs. When activity slows so too will the CPU which in turn reduces temperature. They will rise just as quick if a user or background program needs to do something more intensive. I'd also look to HwMonitor http://www.cpuid.com/softwares/hwmonitor.html and Speccy https://www.piriform.com/speccy/download/standard to see what other health monitors/utilities are saying.

Thx for your answer. Yeah, im pretty new to watercooling
But i already used the HWMonitorve. Its the same there, every core spikes differently from 30 to like almost 60 in a different "pattern" within like 5 seconds. The strange thing is, that a friend of mine got the same cooler but with an i5 and he says that his cpu stays in the range of 30 degree celcius all the time. I havent done any overclocking yet.
What worries me the most is, that it flicks up to 60degrees without me running anything, since i wiped my ssd there arent many background programs. The load is about 18% of the cpu.
I understand Temperature variations, especially when my CPU has an turbo boost in it. But temperature variations from 30 to its double seems like somethings wrong...
This guy has the exact problem as me, and has about the same componements: https://www.youtube.com/watch?v=cFDbcOaUJn0

So, your CPU is jumps to 18%./ That's only part of the story. Why? What does your task manager say? Click on the CPU tab within the task manager to sort them by their individual CPU usage. It will tell the why.

Video response: He is seeing turbo-boost in action. It does take some resources to open a browser and start all of its plugins and everything else it depends on. It however is done very quick. It's obvious mhy his temperature spikes for a second. Turbo-boost kicks his CPU up to full speed so it getnerates more heat during that window. Okay, I got that carnival set up, says Windows. Break time people. Go ahead and relax. The Skeleton Crew can handle things. Then the temperature and CPU load goes back down.His H100i reacts accordingly. Okay guys, the 6700's making some heat let's get to work. What else would that guy expect? CPU spike results in more power to CPU which results in more heat produced which results in the fan spinning up to cool the CPU. A well oiled machine it looks to me. He then compares apples and twinkies. The 4770 and the 6700K. While their max TDPs may be sorta similar the electricity consumption, the resulting heat dissipation, performance and other characteristics will of course vary. YMMV. Your mileage may(or will) vary. John Doe's 6700K overclocked to 4.6GHz on air with a simple ratio change. May Jane's 6700K Won't go past 4.4GHz. She calls John and compares notes. WTF? Mine must be defective. Mary Jane would need a minor voltage change to get past her wall. That's a normal variation and not a sifn of teh chip being defective. Overclocks are not guaranteed(or protected by warranty in Intel's case)... Anyways that's just what is known as the silicon lottery. Not all 6700Ks are made alike. Think of CPU like snowflakes. Each and every one is going to behave differently due to each piece of silicon not being exactly alike. And obviously a Haswell and Skylake will react differently. If he doesn't want his fans to rev up when he opens a browser he needs to change his fan curve. MSI's afterburner has a GEAR next to fan speed. That allows the user to create his/her own fan curve. He can tell it to not increase RPMs until it reaches 45C. That would be a less aggressive fan curve. I'd send him over here https://www.youtube.com/watch?v=Nf9_DTKpPkY . The CPU and heat spikes are expected due to Chrome. Your spikes have yet to show their instigator. Your task manager has the answer.
