Today on my test bench I've noticed some white marks on my CT3900 AWE32. Never noticed it before. Only appears on the backside, I tried to clean it with a Qtip and some IPA, it instantly disappears when I touch it with the alcohol but reappears exactly as it was after a few seconds.
Card works fine as far as I can tell. From the opposite side it is a small cap, picture attached.
Sorry about the potato pics, it's late here and my room isn't very bright 😁 I can try and provide better pics if necessary.
