HAHA- oops, I meant 3.84
The t-line is a long story, but in the end, it's eaier to drain.
My r50s were getting pretty warm before I put those ramsinks on- They also stopped the squealing sound from the chipset area.
Thanks for the warning about the pump- I didn't know there was a bad position- I've been planning on bolting it to the inside wall, but haven't gotten around to it.
I've also been planning on removing the T-line to reduce clutter but I don't feel like draining the system for it- and I guess it doesn't hurt anything.
