After constantly fighting with loud fans, heat, and dust with my computer, I stumbled upon PCC's video about submerging a computer in mineral oil. I researched it further and ultimately decided to try it myself. There is no noise at all, even my new computer in an Antec 900 case on lowest settings is unbearably loud after experiencing the lack of noise from this system. The only way to tell if its on is to see if the fans are spinning :) Total stability as the oil equalizes the temperatures from all components. And its completely dust free forever! In the second half of the video I purchased a small 70gph water fountain pump for $20 and a heatercore for a 1973 Ford F250 for about $14, 1/2" vinyl tubing and clamps $7.
Please comment! and I will try to answer any questions to the best of my ability.
