I doubt it, but you seem to have physical evidence of it. I actually don't think it's (supposed to be) any different than CPU_SUSP_HLT, and I'm a bit mystified as to why VCool seems to make a difference on my W2K system. I didn't know about CPU_SUSP_HLT before, so I'll put that in the kernel and see how it works. >(For the thermal paste, get a piece of hard plastic with a smooth straight >edge just a bit wider than the chip and spread it real even but real >thin.

I'm >guessing that putting it on both surfaces is more apt to leave bubbles.) I used a razor blade, but the plastic sounds easier to handle. Problems with the thermal paste application may have been caused by my manipulating the rather large heatsink and fan combination so as to get past some nearby capacitors on the motherboard, and then get the @# $%^*! clip seated - I did some wiggling, which may have introduced bubbles. Hopefully, practice will make perfect. Jud To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
