18-Sep-99 - Dugedug (from the newsgroup alt.comp.hardware.overclocking) sent some pics of his watercooling setup:

Temps are usually within 2 deg C of room temp. Under load it is 5 deg above that. I have both my week 29/32 c400s at 600. 582 for unbreakable serving under nt 4.0, 600 under win98 for gaming(dual boot sys, the watercooling is on the cpu that gets the load under win98). My 3dmark 99 is 5470 @ 600. I'm available for questions.
