Yup, it's awful. No, I won't check the thermal paste in both of my now out of warranty GPU's (not to mention that I've never done so in my life) because I have no thermal pads. I don't have much thermal paste left either.
I need to clean mine out as well at some point, i already noticed a layer if dust laying on the floor of the case. I think i'm gonna wait a bit longer cause i'm thinking of putting in another ssd while i'm at it.
