Just got my u-120 X and I have to say I'm a little puzzled. The base where it should contact the heat spreader is not smooth at all, it's actually grooved! You can see a scratch which is where I gently ran my thumb nail over the surface; I could feel the rough edges. Is this normal? If you own a u-120 or u-120 X, is your HS like this?
