What to do with these copper wires?

I Got some copper wire or you can say i got it from the wire and it's all copper(Not sure if it's 100% copper) but is it possible to do something with it to help cool my CPU down? I got i7 950 with Tt V1 AX cooler and it's not doing well of cooling my CPU as it not going down or under 54*C(Lowest i ever seen even with the lowest voltage and speed and 1 core with HTT off which cant even go down 55*C)
BTW, Those aluminum on the Tt V1 AX heat pipes, can it be removed, Can i scrape it off? because i plan to put it on the heatpipes by making a whirl line around them to the next, it's about a yard long or probably a bit shorter...

heat sinks are made with copper pipes because copper heats fast and also transfers heat very quickly. aluminum on the other had absorbs and cools down very fast. thus you see copper pipes in aluminum fins.

the copper tubes are hollow with very very thin walls, you want heat to transfer fast not slow so you need very little material to acomplish this.

I have soldered copper pipes into laptop heatsink fins to install water cooling, thats the same premis as what you are suggesting but i dont think its needed.

55c is well with in safty margin for a i7, hell anything below 90 is fine. i would go and spend 30 bucks on a new heatsink like an arctic-cooling vs trying to build your own out of these parts.

if you have lots of copper i think they give you 4c per oz of it at the scrap yard.

I'll plan to get a CM212+ and give this back to my brother or to one of my brother that have a LGA 775 CPUs since it cant even cool the 1st Gen i7... BTW Im lapping my CPU, im not done but IDK why it's so hard but I been doing it for an hour every few days and it barely got all the aluminum off still a bit left, first day i tried it was 5 hours straight, got tired but still doing it now, i got so mad, i started pushing it down so hard that it got through quicker lol...

oh god why are you trying to scrape all the aluminium off?!?! lapping is just making the surface flatter so that the contacts between the heatsink + cpu are easier, and in testing it only helped temps by 1 - 2c at most....

please please please read up on pcs and what you are trying to do before doing it :)

my i7860 is lapped... and yea a 2c difference is pushing it, more like 1.5 in my case
October 9, 2011 4:57:59 PM

also i see reports of lapping only taking 2hrs ... so ... why is it taking you days and days... for the love of god dont expose the innards of the chip o.o

i doubt he is doing it right. laping needs to be one on a very very very flat, stable, smooth surface but it only takes seconds of time with the CPU on the disk I used an old pottery wheel i had in the basement and bought some very high end polishing grit plates and held my cpu on the large disk with a small track to stabilize it while i turned it with my foot at a slow but steady speed. works great for me. the key to this is its a hell of alot easier to put the CPU to a large sander vs putting the sander to the small cpu

My sand paper is very small like probably 5 inch in high and 2 1/2 inch wide... It took me long because i dont got the lapping tools or those 200 through 2000 grip sand paper... Im currently pushing it down pretty hard on a(Probably) 800 grip sand paper and it's doing well but it'll take awhile since im so tire of lapping it... I do it at least 20 minutes to 1 hours in every few or once a week lol... My bro my PSU because his dies plus he need to do his CS5.5 and stuff as well as my Video Card lol... I Still got till next year or in Q1 2012 which he will get a new PSU and GPU... BTW, when i lapped my CPU a little bit, it helps by 1-2*C and after im fully done with it, it should probably drop by 5*C at least since the heatsink was touching the top and the bottom in a little square(Like bumbs and there's 2 on top and bottom) so it didn't tough the sides or the middle nor the corner, just a little spot where heat barely transfer through lol... I also got all the Aluminium off the CPU just recently like an hour ago from now lol(Except a little bit on all sides/4 sides)...

BTW, Should i sell my computer now(Since it's out dated and i bought it like the end of 2010 or early 2011 where i didn't know anything about SB) or wait till 2013(Intel's 22nm CPU/Intel's Haswell) or 2017(Where i graduate from school) to get a new computer because right now im planning to keep my computer for gaming and for browsing and for homework(school) and i might go to college

what do you mean you got all the aluminium off.... can you take pics, im really worried about that cpu :p 

and selling it is up to you, if you think you can get a decent enough price to buy a new one then go for it :)

the 'aluminum' is what transfers the heat from the dies to the heatsink. its not meant to come off... that's what is meant to be buffed or lapped. you need very very very high grit sand paper, well above 2000 for a proper lap job and i dont see how anyone could do such a thing by hand to a proper degree to make any difference in temp. 800 grit sand paper? i dont even use that to sand a car body... you need to get some higher grit paper...

as for a new comp it depends on money. you can build a comp tomorrow for under 1300 that will last you a couple years easy.

Lol... Same... IDK What i just read lol... Also i'll try to get a 2000 grit or higher sand paper but IDK where to find them -_-... My bro being an ass not buying(Buying from online) or using his money(Credit Card Account) on these $10 sand paper(For lapping) even tho i gave him $10(Which i would if he bought it) but he wont so i'll have to go to the store to get some myself because im at age 14 right now and IDK where or have anything to get the lapping sand paper... I'll upload a video of it soon probably in a week or so because i got school and i wake up early every morning on school day to do this because at weekend, my family use computer 24 hours a day and when i get home from school i still dont get to use it so i wake up early to do it and to upload what i got... It's 5:55 AM right now on my time and i wake up at 4:00 AM...
