I am very happy with my v3 performance wise. Been running it since it was shipped as one of the first replacements for the v1/v2s. I put about 5-6 full packs on it every weekend at the track. I temped it this Saturday and it came off the track after 20 minutes at a whopping 69 degrees. Of course, it was only about 35-40 degrees inside the track area, but still kick ass temps.
