Bought new GPU, Installed it and now my CPU is running hot.

So I got my new GPU, the GTX 1070 Gaming z. I installed it, and ran a few test runs on some games. It all seemed fined at first, until I noticed every fan in my PC ran at max speed (Except for the MSI).

When I installed my GPU I accidentally made a small bump on my intel stock cooler on the CPU, so it feels a little lose now? Could that be the problem?

At idle the GPU sits at 30 c (boot) -> 41 c after a few minutes of running.
At idle the CPU sits at 45 c (boot) -> 80-95 c, when I try to start a game of League i.e.(Which I shut down right after)

Any suggestions to what I could do?

Since I didn't install it myself, I have to ask:
1) It has to be solid? No wiggle room right?
2) Does it matter which thermal paste you buy, also would you recommend buying thermal surface cleaner?
 

1. It has to be solid, no wiggle!
2. There are several different kinds of thermal paste. All are within a degree or two of each other. Arctic Silver 5 is well thought of here.
Just use Isopropyl or rubbing alcohol as a solvent and a coffee filter paper or other lint free cloth to clean the old paste off.

The bottom 2 "screws" were a little lose. I tightened them and now it seems like the cpu runs at 75-80 C, it doesn't surpass 80 as it did before.
Would it help to buy a after market cooler?

I'm just asking, since apparently thermal surface cleaner is quite expensive in the stores, and rubbing alcohol is not.

Woops spoke to early, it goes to 84 - 90 c some times now. - Is this dangerous for the CPU?
 
Not necessarily dangerous as the CPU will throttle down if it reaches a certain temperature to protect itself. Your performance will then suffer. 84 c is quite hot. If it were me I would clean both the surface of the cpu cooler and the cpu with rubbing alcohol and re-apply new thermal paste. If that doesn't lower your temps significantly, then you should look for an aftermarket cooler.

Just go get some rubbing alcohol, it works fine. Order you some good thermal past like NT-H1 from amazon. After market coolers are much better, the cheapest Noctua will be better than any factory cooler.

You should provide some more info on your system too. Like CPU it has. That makes a big difference in temps. My 5930K naturally runs much hotter than my 6700k.
