OT: Artic Silver Burns, and comes apart when you overheat it. Smells like black Coffee too.

First off, I am a total Idiot. Just thought you should all know.

I bought a mainboard from a buddy of mine ( ss7 ) for a k6/2 500 that I had laying around. I poped the k6/2 500 in last night, ran it for a while to make sure it worked, then left it on all night running SETI.

When I wake up ( about 1 pm. I love being unemployed :p ) my entire room smells like coffee. I hate coffee. For the life of me, I could not figure it out. after lookingg for the spilt coffee, I decided to check on that system. Low and behold, the frigging case smelled like someone dumped a bucket of coffee on it.

It is still working, but the CPU fan was no longer spinning ( looking at tit later, I see that some of the plastic melted! ) I turn it off, and go to remove the HSF from the CPU, and burned my frigging hand. It was like 200+ degrees! It was insane!

CPU pic Hard to tell, but the AS2 turned into a yellowish thick liquid, kinda like a thick cooking oil, and silvery powder.

HSF pic Little easier to see the seperation on here. The more interesting thing, is wherever the AS@ was not compressed by the HSF it was burnt.

what did we learn?

#1 Test a computer for more than an hour before going beddy by.
#2 AS2 will seperate under extreeme heat and pressure
#3 Don't touch a HSF till you are sure it is cold.
#4 Burning AS2 smells like coffee. Keep your nose open.
#5 Evadman + K6 series CPU do not mix. ( second one I burned up in 2 months. First one I welded to the HSF )


Good life lessons I think. By the way, I still am not sure what did it. I think it was being fed 5 volts instead of 2.2, but there are no jumpers on the board besides DIP switches for the speed. I assume it is done in the bios. Bad Bios.

Board = Trash now. And I almost spent money on it. :p

:Q :Q :Q

LOL!! :p
(or maybe the antithesis of LOL! :;)

The problem with those K62s is that big heat spreader on there that you'd have to goop the AS2 all over. Well actually, not goop it on but put a thin layer on there... But I don't understand why you had such a problem with yours.... I am OCing my K62-500 to 505 (lol :p) and I have AS spread on it under the generic HS and it has been running F@H pretty much non-stop for at least a year... Mine is in an old Compaq Presario. I haven't had the AS burn up like that on it though... :(

But, this post made interesting reading though... ;) :p

[EDIT - Did it really kill the CPU?]

poof: Yep, that CPU is deader than a doornail. Wierd, because the one that I welded together ( I had to pry it apart with a screwdriver ) still works. I had to sand the HSF down to get it smooth again, but it still works :p

My suspicion is that the fan failed first, precipitating the overheating problem.

One question: Why bother to run SETI on a K6-2? It takes like 2 days to do a WU!

1 day 2hours on a k6 266 that I have running. This is 2x the speed, and was going to be doing nothing but crunching. Everything else I have is doing somethign else.

Is there a DC project that would make better use of it? I would be happy to do something else. Well, when I get the next one up anyway :p

I run SETI on a P133 :p:p:p WU can be anywhere from 1 - 4 days :Q:Q:Q
It's not doing anything else, why not.

Tis a shame about the loss... ;)

My K62-500@505 can do WUs with the CLI and windoze 98 in about 25hrs, which isn't really that bad...

But I have it running F@H and you could probably do a bunch of different projects on these (at that 500Mhz speed ones) if you don't mind the electricity...

I feel for ya. I've touched a hot HS before and burned myself. :eek: The good thing is, you'll only do it once! ;)

It sort of does look like you put a bit much thermal paste on the HSF. You surt it was the actuall arctic Silver? There is a false brand.
