Are very fast fluctuating temps on the 4790K normal?

I used to have a 4670K with an NH-L9i, it kept it cool enough, and temps always rose or decreased steadily, with a few exceptions.

Now, with my 4790K and NH-U12S, my overall temps are lower, sure, but they fluctuate a lot more. BF4 on a 64 player map hits 64C max, Dragon's Dogma hits 76C max in one area specifically, every time, but stays below 66C most of the time. GTA V stays below 60C, Skyrim gets to 64C. Even at idle, I see it jump from 26c to 48C and then right back down. In games it jumps from 50C to 60C, etc. This did not happen on my 4670K. Is this a bad paste job?

64C seems to be an overall max. Is this ok for stock clocks on a 4790K?

Make sure you have tighten down the screws enough.

i havent yet seen my 4690k at 4.1 hit more then 62 degrees while under load on my 212 evo with noctua nt-h1 thermal paste, thats under a full aida 64 stress test, but before i didnt have a great application and i was always at mid 60`s and my temps were always a max of 72 degrees,

It could be a bad paste job, especially since you suggest it as being an issue meaning you think you did a bad job of it. I'd sitting 64C idle is kind of normal but the 26C to 48C is not.  Could be faulty software, but I'd suggest reapplying the paste see where that gets you.  Also, check the temps of the individual cores, because that can be a strong indicator of bad pasting.

They were tightened until I was afraid I would destroy the threads.

It just jumps to 48C at boot and rarely jumps that high when at idle anymore.. Individual cores are all within 1-4C of each other. Is that ok?

If they all jump up to around 48 then back down its because something is using ur CPU dude

Run a stress test and watch the temps they should reach a limit and stay there

Yes that's fine, but the 20 degree C jumps are not very normal, could be extreme CPU stress make sure everything you don't want running is off and I'd try re pasting.

I'd rather not re-paste right now if this is safe. Once my leg is all healed up I might give it a ago. I mean it does only happen at boot most of the time, when everything is booting with Windows it seems.

Then it's probably fine.

But during gaming the fluctuating temps are normal? Is this just a thing with Haswell i7s?

if I start a stress test temps just from 15 straight to 60 they don't gradually increase

His CPU is fine it's just something running in the background, especially if it's at start up
