test of thermal pad on AMD
amd's web site recommends pads, not grease.
If grease is better, why are they recommending pads? |

If you'd run SETI for a week with the pad, checked temps, then tried goo it would have been valuable data, as it is, it's junk science. -- It ran 24/7 for 2 days, how long does it need to run to -start- working right? 48 hour should be getting close, *if* it was under 100% load for that time, say, running Prime95. It's phase-change material, meaning it needs to get hot for a while to do it's thing. BTW have you ever looked at the surface on the bottom of the newer HS's they give you in the retail box? Looks like it was surfaced with a 40 grit grinder. Yep, they're pretty rough alright. -- ~misfit~ |

Cheap smoke alarm with a relay? Maybe you'd want some help with keeping the relay contacts connected - I suspect it would eat batteries. The other concern is of course fail safety... no point in having a battery open circuit the relay - when the battery runs out, it'll close again. Besides, if the thing is on fire, there seems little point in switching it off. Kind of a bit late? I was thinking that cutting off the power might help stop feeding the fire as the fan was going up in flames. I actually observed this happen with a house fan a few decades ago. |

Yep, they're pretty rough alright. Maybe that's the real reason why they are saying not to use paste anymore? The retail HS's are so rough it wouldn't work? Seriously, I would bet a lapped HS would cool as well as this rough one did with a pad. But no, I'm not going to test that on this machine. :-) -- Stacey |

I was thinking that cutting off the power might help stop feeding the fire as the fan was going up in flames. I actually observed this happen with a house fan a few decades ago. Why not just put a solenoid valve on a fire extinguisher and connect that to the fire alarm? I'm trying to get somewhere in that direction. Since I think we would agree that the probability of fire is very small but we want the probability it will successfully work if there is a fire to be very high then I'm a little hesitant to believe in a hobby-modification project to make this work. I am still looking at all the possible solutions to this though. Thanks |
