To steal and warp the lyrics from a popular Broadway musical of yesteryear, "It's gotta be thin." It's hard to believe that "a little more" thermal paste is a bad idea. I added a bit of AS--for safety recently. After getting un-lazy, I removed all the AS from the HS and
CPU and re-applied a paper THIN layer on the top of the
CPU. Shazam, my
CPU temp dropped a solid 4C. Less can indeed be more.
I hope this aids your temp sitch. If not, I also have a Vantec CCK-6035D that I haven't installed yet. Two unhappy campers? Argh.
