After months of troubleshooting and going back and forth with Intel, I am still having overheating issues. Intel has replaced my cpu, MSI has replaced my motherboard, and I know that my cooler is working because the water temps are high and the tubes/rad are painful to touch. My pump is working, it displays 3000rpm. I have reset the board, turned off xmp, manually set the clock and voltage to stock, hw monitor displays safe voltages, I have re installed the cooler many times, and it worked in my friend's before I bought it from him. I have no idea what is wrong and none of the things Intel told me to do worked. I have tried not using the g.skill ram, still same problem. It is not windows related because the temps are high in the bios too. I have also tried lowering the clock speed and disabling multiple cores, none of these have had any effect on temps.

Solution
My guess is that your power supply is causing this. If you've replaced literally everything except it, then that's the only thing that is common between your RMA's and part switching.

That was the next thing I was going to try, literally as I got an email for your reply I was booting up my computer with a spare power supply and that seems to have worked. Load is now 60c and idle is 40c. It still seems a little high to me but I guess it isn't too crazy considering 32c ambient. None of the other threads I read said anything about a power supply issue so I hope this helps unexplained overheating to someone else with the same problem. Thanks for the input.

This is only the second time I've seen something like this. Situation was nearly identical. The guy had replaced literally everything except his case, PSU, and hard drive.
Your temps look good now. 4790k can run a little on the hot side.
