is paint a problem on HS?

[DatHak512]

oaky... i've just got a random question...

if i've got an older-ish HS and it's got that baked-on black paint on it (it's called something, but i can't remember what exactly) does that impede heat transfer from the sink to the air signifigantly? if it does, is there any way to remove it, short of some sorta high-tech acid bath???

just curious... thanks

Paint is very rare on heatsinks, and it does impede heat transfer. Are you sure it's not anodized?

 

[DatHak512]

hmm... all i know is that it's black paint on an oldish heatsink (i think from an early model eMachine ) it may be anodized, but i don't know how to tell the diffrence.

taste it

 

[DatHak512]

lol uhhh... what am i tasting for, exactly?

"plafstik schtaste. orf acidsch taste.
just thried mihne... acidisch."

*Allow the heatsink to cool down.

heh... yeah i 45C heatsink might burn a little.... : ) i'll give that a shot anyway... lol

so next question: (the winner gets $20...) (okay not really)
how do i get this crap off?

lead...? if it's REALLY old

no, it's probably not paint, I've never seen a painted heatsink. It's almost definitely anodized. and it will be pretty hard to get that off the fins. you can easily sand it off the base though...

 

[DatHak512]

yeah... i guess i'll have to live then. i was thinking some kinda acid bath, but hey... i think that's a little outta my range here. 'sides: don't want to melt off any hands or anything!
they made heat sinks outta LEAD?! (or was that just the paint?!)
i'll sand the hell outta the base. lap it. i used to know a good lapping guide, but i guess it sorta fell through the cracks... anyone have a good one or know where to find a good guide? thanks.

no, i was referring to the old lead paint that kids used to eat because it tasted good...

you can blowtorch it for a while. just don't leave the torch in the same palce for too long or the heatsink will melt. (i tried it. its fun)

ummmm, ok, guess you like playing with fire

doesn't everyone???

really though, the blowtorch i have is probably the coolest thing i have except for my computers, though that is debatable, as you don't get cool flames and melted stff with computers. well, as long as you do it right...

the only problems i can tell with blowtorching aluminum to de-anodize it are it can melt it and it discolors it a bit. (it looks yellow-gray. ish.)

ya, but i ain't taking a blowtorch to a hs for no reason

besides, i prefer big explosions than a whimpy blowtorch

 

[DatHak512]

that sounds like a pretty good idea... with the blowtorch and all.... besides it's fun : ) i'm not sure where i could get my hands on a blow torch, but i think i could manage that somehow.... is it possible to just use a low-temp, clean burnging flame to do the same thing?
but... would the crap left over from the burnt {whatever it is} impede heat transfer more than in the first place?

This happen to one of my old TB's when the vcore kreeped past 2volt and a cheap alu heatsink didnt knew what he was expericing.

LOL, but i didn't relize the old athlons had a heatspreader?

 

[rogue_jedi]

kllrnohj: i think that's a k6-2, which do have heatspreaders on them. dunno why amd dropped the heatspreader on the socket a chips.

Dathak512: lowes has a micro butane torch for ~$20. should work great.

Buy two. Use one to blow the other up... Er, better not.

i hav a few of those heatsinks, assuming i understood what your description meant

i hav two slot PIIs with those heatsinks and also a pentium heatsink

i kno its paint because it has a few scratches on it and the deeper ones show bare metal

thanks for the tip, im sooo gonna try that now....

anodizing does the same thing... i'd think it would be anodizine because it is easier to get a uniform coat that painting would give (just requires giving the thing an electric acid bath)

Please realize that I'm poor and will not be capable of paying your medical bills...

BTW, when a heatsink is anodized, you can scrape down through the anodiziation and get to 'bare metal'. So, yeah, it's anodized, not painted.

Speaking of painting, I have to go at my hood ornament again.

lmfao That's the perfect way to do that, too. I should have thought about that while I was still in High School...

Anodizing is using a chemical process to change the color of certain metals, including aluminum, without using paint.
