Penny Ram sinks....

First off all, i know this isnt my origional idea. I give credit to the person who hosts the Ghetto Mods site (maybe Afroman i think). But seriously, if you sand them smooth and glue them to each other off center (to make fins) with thermal glue or just as3 and superglue, you have a copper ramsink for like 5 cents plus cost of as3 and glue. It seems like performance would be the same as the ones you can buy for like $20 for 5. Is it a looks thing, just dont want to take the time to make them thing, or do they really offer performance over the penny sink? Thanks

Pennies aren't 100% copper (too expensive) they're actually only copper plated.

Thus, I don't think pennies are anywhere near as thermally conductive as even aluminium!
 
See the thing is that pennies from before 1984 or something like that were like 95% copper so the conductivity would be good on those.
 
But are you gonna go to the bank and get a roll of pennies and pick out the ones that are before 1984? 😕

Also, even a little bit of impurities can destroy the thermal conductivity of metal, from my memory. Anyone care to correct me on this?

Haha the reason why i ask it becuase i have two huge jars of pennies that i have been collecting since i was like 3. When my dad would empty the change out of his pockets when i was little, i would put his change into a big jar. I did for a while and eventually sorted them out and i ended up with like 40lbs of pennies. I just recenetly rediscovered them when i was cleaning my closet and it got me thinking about the penny sinks. So i have alot of old ones that i could use.

Try it out and let us know! Overclock too .. 😉
 
pennies made before 1982 are mostly copper.

edit; you'd also have to clean the hell out of the pennies anyways, and make sure theyre smooth to get good contact with the ram (which is illegal anyways - modifying money - but i wouldn't get scared over it)
 
Sure cant hurt anything since ram sinks are pretty much a gimick anyways.

I disagree, I've seen computers with ram getting too hot, especially the Ti4200 boards, and a set of ramsinks allows for greater stability, even at stock speeds.

Only if the secret service raids your house looking for their lost pennies. 😀 But if they raided your house, they would probably get you for all that illegal music, and those movies, and all your burned software, and in the process, forget about the pennies stuck to your video card.

You have a sensible point here... 😀
 
When I was sanding down a penny for a spacer on my P4m, Iwent through about 3 of them before I found an all copper one.. circa 1964
 
I was about to say... what do you need heatsinks for on RAM? You didn't say you were talking about video cards... video card RAM gets pretty warm, sometimes... kinda... well maybe... Why don't a lot of 9700 Pro cards have heatsinks if heat is such a problem? 😉

If you're puttin heat sinks on your system RAM... I have a bridge to sell you too...
 
i stuck dimes on the ram of my old v3 2000 using the method described here. it got me an extra 5 mHz, so i can't complain. of crouse, my method was 10 times as expensive as the penny method, so YMMV. 😉

Actually you'd be doing the Federal Reserve a favor by destroying the old copper currency, since they destroy all the stuff that's over a certain age anyway, and 1984 is plenty old enough. Of course i'm sure if you want to get nitpicky you could say the government would see it differently, but ehh...
 
No bc id have to use more than one penny. I probobly stack 5 on top of each other. I was thinking about putting the sinks on my video card and the mosfets on my mobo.
 
The Lincoln penny was introduced in 1959 and minted until 1982, when the rising price of copper dictated a change in its makeup. The penny's composition was changed from an alloy of 95% copper and 5% tin and zinc to 97.5% zinc and 2.5% copper.

The Federal Reserve destroys paper currency when: it is damaged or too worn to continue being circulated : the money supply needs to be decreased in order to change the federal reserve holding ratio. While the average life of a $1 bill is only about 18 months, older bills in good condition are not destroyed because of age alone. Or so I was old at the Kansas City Federal Reserve in the late 80's.

They do not destroy coins. In fact they don't even count them or judge their condition, value of bagged coins is determined by weight at the Federal Reserve.

The Secret Service has a few hundred thousand tacky jewelry shops to raid for cutting up Mercury dimes before they'll get to you.

On average the Federal Reserve shreds about $75 million worth of old bills. If you'd like some destroyed money, write them.

If you want ramsinks, buy them or dig in your pockets. 🙂
 
I know You think that this is a way to save money... But just remember that time is money too... And I myself rather have the time... That's alot of work.🙁
