At first this problem was very subtle when i built this computer. I looked into it further and people told me it must be air pockets, so i did the whole tip your computer over for hours to let the bubbles work their way out. After that it seemed to go away. Now, 5 months later ive been dealing with this very loud clicking noise that i can hear from another part of the house, with the door closed. I thought the sound was coming from the HDD so foolish me gets an advanced RMA from Western digital, my bad for not doing a better inspection into this, because it was obviously coming from the water block.
So now I cannot figure out what to do next, if it is to deal with thermal paste, i have very little experience with replacing and applying thermal paste, what is the next step for me to do?
