I got the H110i GT and love it. If your case says it supports radiators then you will have clearance.

I've got an H7 personally, and it has no issues with super tall vengeance modules 

neither does the R1 universal (not ultimate)

Did you check the cable connections? I have the same monitor and it did something similar to that when the cable wasn't plugged in correctly/all the way.

Try using integrated gpu and see what happens 

Still listed on 144hzmonitors' recommended monitors.
 
There have been more recent releases of cheaper Freesync monitors, but those don't attempt to match monitors like the XG270HU.

Stick with what works IMO, if you have never had issues with it i dont see why not just stay with whats comfortable. the 502 is one of the highest rated mice for performance so you dont gain anything other than trying something new which isnt bad but might not end up the way you want.

You upgraded two things at once? Then we need to eliminate one of those two from the equation. I'm guessing you don't have a second monitor to test, so plug the old graphics card in with the new monitor and see if the problem persists.

Ok thanks, I thought samsung 950 pro also works as a ram, I will buy some ram tomorrow. But is a heatsink really neccessary? Because the case already comes with 3 fans, one above the power supply and two in the front.

This is how I feel about this build along with the builder:
 

When I read that and imagined what would happen if he didn't. I got a rush of adrenaline.

*see's a person who has built a dual socket box, yet thought their SSD was also RAM and didn't know that heat sinks would be necessary*
