Using pennies as ramsinks?

aolforbroadband · December 20th, 2003

I read somewhere that using all copper pennies on as video ramsinks to dissapate heat works well, especially using arctic silver compound. I was just wondering if this was true (gets pennies ready)

**hushypushy** · December 20th, 2003

well pennies arent solid 100% copper, just to let you know.

Chinoz · December 21st, 2003

I recall Hanamichi suggesting that idea once some time ago, but the surface of the penny ain't 100% flat, so unless you pound it with a 5kg hammer or something, you might not be getting a good contact point

Get a 486 HS, Cut it into 4 with a hack saw, file and sand... Easy Ramsinks...
Nice for those VideoCard Ram (almost all use 4 pieces of ram)...

it'll work but you would need to pound them flat and then if possible use flatten as many pennys together on top of each other as you want to get the maximum possible surface area

I think a blowtorch might be needed to change them into proper ramsinks

op3n_skill · December 21st, 2003

isnt copper hard to melt/Work with? IIRC, it's a reason why Copper HSs are damned expensive...

Player-X · December 21st, 2003

Or a welding iron

**hushypushy** · December 21st, 2003

but pennies arent 100% copper, are they? i dont know about other countries tho....

which reminds me, canadian pennies are really small....

>>but pennies arent 100% copper, are they? i dont know about other countries tho....

yup.. Copper coins have a mix of other metals (look at the side of the coins, Some have layers altho some not visible)..
Older ones tend to have more copper than other metals...

One thing i observed in my coin collection is that Pre-WW2 Copper coins tend to have the green-rust while newer ones (subjected to same conditions, yeah i have too many of them that i dont care about some of them, and they get ketchup once in a while) Take longer to do so..

If pennies would work, how would they stay still?

**hushypushy** · December 22nd, 2003

you would put some artic silver on em or something

Arctic Silver is thermal paste not glue. If you used it for holding pennies on RAM, what most likely would happen is that the pennies would drop off, shorting something and frying your mobo.

**hushypushy** · December 22nd, 2003

well i figured paste = glue. thats what i learned in kindergarten anyway

You should probably lap the pennies first. Then solder them together somehow. I would rather spend $7 on a pack of cheap ramsinks.

Edit: Oh, and its against the law to deface legal tender.

green-rust

welll..... it must be some copper compound.... certain reactions turn coper into a greenish substance (don't remember which one...... haven't studied inorganic chemistry in ages) one thing I remember quite well is that nitrogen radicals turn copper into a blue substance.

the reason for older coins to "rust" faster is that they have more copper per coin than newer ones.... and those metals included in newer coins act as a protective shiled for that reaction.

That's an Americanism, I'm afraid. The only paste that is like glue in English is Wallpaper paste. Thermal paste's only defining property is that it conducts heat well. It does not make things stick well. If that were true, you'd never get your HSF off the CPU once you put it on.

Copper oxide is green. Rust = oxidisation.

dammit i guess i shouldnt have melted together 4 bucks worth and stuck it all over the inside of my computer .....

anyway, yeah you're right Kane. America will always make more words to mean way more things. American is the hardest language to learn

was it the green tone?.... I swear i thought copper oxide was silverish.... but then again, I haven't studied inorganic chemistry in ages

op3n_skill · December 22nd, 2003

Yes, Copper Oxide is Green... It's one of the main problems concerning Copper HSFs and WBs (One of the biggest headaches in my collection of mint coins)....

I think what szl is thinking is a form of heatspreader, not heatsinks.... So the ram can dissapate the heat faster....
Just take some pennies to the railroad tracks to get them nice and flat...
