actually i've never used those fluids... but i'd like to give a try someday... i've heard good stuff about primochill's on their duration, but not for fluidXP... ?? have no data for this one in specific but OcUK don't sell primochill

if you have colored tubing (i have black ones) you can use distilled water + cooling fluid for cars > looks kinda faded but you can't see it (i use a 50/50 ratio and it's been like this for over 18 months now... in my cosmos s... 2 years in the first build)

the good thing about primochill or fluid XP is the fact that they're non conductive!!!
had two leaks in the past and got my graphic card full of water (in both build... gotta check this on the next one ) ... i got lucky 'coz it started back again once everything dried, but it's rather scary when you get that BSOD !!
