Try spreading a thin layer accross the surface just enough so you cant see anything but silver then add a rice grain size in the middle might help create a better contact and tighten those screws until its hard to turn them anymore by hand.From what you say it does sound like it's not making proper contact and is not fitting properly on that board ? have you tried taking the board out and seeing what the idle temp is when it's run outside the case
Which case have you got out of interest ? if heat is building up in the case it will be like running it on a hot summers night and we all get high temps then.
Also are you sure the fan is running ? as 50 idle sounds like what it would be without the fan on.
To see how concave your chip is get a straight edge on it and hold it up to the light.
