GUIDE - Nerd cooking for you and your friends

post #1 of 4
Thread Starter 
Hello OCN ! biggrin.gif Let me preface this by saying this is my first guide and I am looking for input and critiques to help me along with becoming a more helpful member of the forums.


This guide will show you how to create your very own key chain, necklace or other accessory form a broken graphics card. Let me say it again, USE ONLY A BROKEN CARD. There are many more useful applications for an old or under powered card. for instance give it to a friend who want to build a PC or there are plenty of console gamer who live in denial and would like to upgrade.tongue.gif but in all seriousness please don't use a functioning card.

End Product

WHAT YOU WILL NEED

Broken/ non-functioning graphics card
Oven
Screwdriver
Fork or some other heavy metal ONLY item
Pizza pan or cookie sheet (preferably old)
Oven mits
paper towels
Large screw driver or butter knife
about an hour of free time (YMMV)

STEP 1 : DISASSEMBLY

So after you have acquired a broken card you need to first take apart the card. for the GTX 295 that I used this was a simple task, start by removing the metal heatsinks for the vRAM on the back of the PCB, after this remove the rest of the screws on the back of the PCB and on the I/O bracket.

The heatsinks simply unscrew and come right off. however this will be different from card to card.

The next step was to remove the plastic shroud covering the GPU heatsinks. I'm sorry that I have no pictures to show this, but it is a quite simple. you use a screwdriver to pry open the shroud by poking it into little openings on the top and bottom of the card.

Now you see the fan assembly covering the PCB. Just remove the remaining screws and this comes right off.

Disassembly Complete, ready for step 2

STEP 2 : PREPARING THE PCB FOR COOKING

After breaking the card down to the PCB it is NOT yet ready to be cooked. The first thing you should notice after taking off the fan assembly is a number of little white or blue squares of gel covering the vRAM and possibly the VRM..The Thermal pads come right off by wiping them with your finger or a paper towel. Same goes for the TIM on the heat spreaders/GPUs .

The next step however is easy to look over and forget about so i will repost it in the cooking section of the guide. REMOVE ALL PLASTIC. this is where the large screwdriver (or as I used , a butter knife) Come into play. The PCIe power connectors are plastic and will melt in the oven, as will any fan headers. This my seem barbaric but to remove them just use a screwdriver and pry them off. PLEASE USE CAUTION. the Power connectors are made of a heavy plastic and the metal that provides power to the board are heavy duty. Be careful and pay attention to what you are doing and you should be fine. More importantly, you won't poke your eye out ,kid.

PCB Prep Complete, ready for step 3

STEP 3 : COOKING

Before we start the cooking process, MAKE SURE YOU HAVE REMOVED ALL PLASTIC FROM THE PCB. please refer back to step 2.

Now we get to play Alton Brown. Set your over to 550 degrees F (~300c) . let the oven heat up. In the mean time we have to get what we will put in there ready.

Get your pizza pan or cookie sheet out , using a fork or another similar ALL METAL item, place the PCB with the GPUs facing down on to the pizza pan and use the fork to prop the card up.The goal is to suspend the card so that when the solder melts the components fall right out and you can tell when to cooking process is over.

Now more than ever I must emphasize safety. use oven mits. remember that you are working with very high temperatures and the components may be hot for sometime after cooking.

Cooking the card took us roughly 15 min to complete. This will be a very odd time for you as there will be noises and components dropping off of the PCB. Just sit back and watch carefully . DO NOT LEAVE THE KITCHEN DURING COOKING

For us the capacitors fell off first, followed by some vRAM and one of the heat spreaders. This is all okay but be sure that the actual GPU(s) come out, as that is what we are actually after here.

The heat spreader on GPU 2 fell off, however the chip is still attached. keep waiting your patience will be rewarded

When the GPU falls Out Continue To Step 4

STEP 4: COOL DOWN

You now see many things have changed sense we have put the PCB in the oven. You may feel the need to poke around and move things, DON'T. just dawn your favorite pair of star wars oven mits and take the pan out of the oven to cool down. I recommend setting it on the cook top so nothing gets burned. Turn off the oven as we have no use for it now. Wait about 10-20 minuets for everything to cool down , before you touch it .

The GPU will look horrible at this point, nothing is wrong. Look at the picture provided below , you see many large bubbles in the PCB around the chip and the chip looks smudged. the bubbles go away with time (and better camera work / lighting rolleyes.gif). Simply wiping off the chip with your shirt fixes the smudging.

Not as pretty as you thought ?

STEP 5 : DRILLING

This step I do not recommend doing at home, unless you are quite handy with tools and have a drill press laying around. We used a drill to put a hole in the heat spreader/GPU As it turned out we ended up just melting through the copper heat spreader, separating it from the GPU and breaking a drill bit. As well they where not kidding when they said heat spreader , this thing got piping hot and we used a oven mit to hold it !

I DO however recommend going to a local auto shop and asking them to do it for you. it should not be expensive and most shops would be happy to help.

Drilling melted through the heat spreader rather than "drilling" it out

CONGRATS ! you now have the nerdiest friendship ring possible ! thumb.gif

thanks to ttl for the idea

Good job.

However using a CPU might be a lot easier ninja.gif

That's true lol. I should try it out sometime in order to see what little quirks it might have.
