Played a crap load of Apex Legends today along with a bit of Battlefield V. After I was done, I just randomly checked the inside of my case and saw white stuff on my graphics card. I quickly shut off my PC and opened the case. It was like white power and if I blew on it, it would vanish. Not sure if this is a coolant leak or something else because coolant is usually oily as far as I know. Anyway, I've had this cooler for 6 years and want to play it safe by replacing it. I'm looking at the Corsair H100i Pro. I guess it will support the 3930K I have? Also, should I just use the fans that come with the cooler or go for something better like Noctua fans? If I should go with better fans, any recommendations for what I should go with?
