#i7 7700k

So i recently got a i7 7700k. You might say that i have a bad cooler or not much paste on. I have a 360mm aio that runs at 2k rpms, It was used in my old friends pc, Same specs btw. I also have a good amount of paste on it, Idle at 30c 4.6ghz. But It goes up to 40-50 at 10-40% load, And over 40...
