i dissasembled my watercooling for a bit and came back to air cooling till i get my new case finished. well, after some complaints about my room smelling funny i decided to investigate. my swiftech hydrx coolant was a year old. when i was emptying it into the bathtub my brother complained that it smelled very bad. my mom said thats what my room smelled like. so im assuming, the "coolant" went bad and began to reek? ive finally gotten the smell out but i will never use that stuff again. thankfully, ive gotten a bottle of fluid xp+. kind of a useless post but i thought it was interesting. what do you think may have caused the liquid to "smell"?
