cpu Is this normal? CPU Ghz and temps i79700k

[HyperLynx]

1. I recently changed my motherboard from a Gigabyte B360 HD3 to a Asus Rog Strix Z390-E, I had a i79700k in my old board and moved it to my new one. On start up I noticed that my CPU would randomly ramp up to 4.9ghz and back to say 0.8ghz or 1.2ghz rather erratically under low cpu usage % while idling, Is this normal?

 

 

 

The images are it sat idling with CPU cooler fans at 100% is this normal?

 

2. My old board didn't have Intel boost technology 2.0 on it so my CPU would not boost to 4.9ghz or anywhere near due to my old board restrictions and would sit at around 70c/80c usually with my Coolermaster Hyper TX3 Evo . Now my new board does have Intel Boost tech 2.0 and so when playing games like GTA it will boost to 4.9ghz and my cpu temp will also shoot right up to 100c when using the same cooler as before is this normal to see such a high temp on boost and should i change to a better cooler like the NZXT Kraken M22 aio?

 

I think I can solve the cooling issue with a new cooler but I am not too sure about the erratic up and down of my CPU speeds at idle.

Its normal for the boost to act like that but if you're getting 100*C its time to upgrade your cooling as well

Is it normal for it to boost even at idle? nothings running and it will go up to 4.9 and back down almost immediately and constantly?

Yes. There is always something running, even if it's only for a fraction of a second.

yes, just because you're not doing anything doesent mean there are not some random processes runing in the background in Windows

Ok, you guys definitely helped out there. Thanks!

 

Could you recommend any good coolers?

I was thinking of the NZXT Kraken M22 120mm AIO as a 2 rad AIO doesn't fit in my case as my ram is quite tall and for the same reason a large air cooler probably wont fit either.

dont bother with 120mm AIOs, they are a waste of money, just grab any decent air cooler you can fit in

I decided to go with the Be quiet Dark Rock 4, will this be suitable?
