Chillers were quite popular back in the old days, these days I am not sure if they are worth the risk and power consumption for little gains.
WC was much cheaper though - I remember using old Vauxhall radiator, used water block and aquarium pump. Probably all of that cost less than a few fittings now.Yeah back in the early 2000's i had zero money to play with such ideas, i was on a prebuilt machine from Dell which i slapped a low end gpu in which lasted me quite awhile. Could only dream of going watercooling or buying a chiller.
