If the lot number starts with "1227" or higher, then it should be a new unit manufactured under the new process

I've PM'd George from Corsair and still no response after a week...terrific.
It's safe to many of the H100 sold in stores/online will still be prone to the problems in this 100+ page thread.
It's bad enough the only decent closed-loop water cooling solution I can have with my case is the H100 so I urge Corsair to speak up now before losing loyal customers.Edited by twitchyzero - 8/6/12 at 9:34pm
