Hi, I have read how to bow the D-Tek cpu block and I understand what needs to be done, but jeez how do you get the replacement o-ring to fit? I am trying to use the thicker ring from the Swifttech GT but how do you get it to stay in there so you can reassemble the block? The ring is in a circle and the block needs a square one and has to be stretched very tight to fit but the groove in the D-tek is so small it will not stay in there for more than 2 secs. Whats the trick? There some other o-ring I should use or do you need to heat the ring up a bit to get it to strech more or something? I even tried putting a weight on it to get it to stay for a bit but I cant even flip it over and put it down without it popping out of the goove. Already spent like an hour messing with the stupid thing lol... Thanks
