Computers get hot. If they get too hot, they dont work right, and some manufacturers don't put heatsinks on all of the chips on the board. Some of those un-heatsinked ones get hot. Too hot. This instructable will focus on putting a heatsink on a chip that doesn't have one and doesn't have mounting holes for one either. All you need is a heatsink, some sticky tack / mounting putty, and some petroleum jelly. (Also known as vaseline)
Here is how you do it.
Step 1: Materials
For this project, you will need only a few things, all of which are very easy to get.
-Vaseline / Petroleum jelly
-Sticky tack / mounting putty
-A computer heatsink, i got mine from a dead motherboard's GPU
-Cotton swabs / Q-tips
Step 2: Roll the Sticky Tack / Mounting Putty
First, you need to roll the sticky tack / Mounting putty.
Roll it into a long thin snake, like pictured. Make sure it is about 3mm thick
Now would also be a good time to clean the bottom of your heatsink.
Step 3: Put the Snake on the Heatsink
Now you need to put the snake of sticky tack / mounting putty on the bottom of the heatsink. Make it into a square, but make sure it is smaller than the chip you are putting it on, or else it wont hold the heatsink on it.
Step 4: Add the Petroleum Jelly / Vaseline
Next, take the cotton swab and get a little bit of petroleum jelly / Vaseline on it.
Put a little gob of it in the middle of your square of sticky tack / mounting putty
Step 5: Put It on the Chip
Now you just put it on the chip on your motherboard. Make sure that the sticky tack / mounting putty square is on the chip on all sides, and the press it on. Hold it for a few seconds to make sure the sticky tack / mounting putty gets a good bond. If the chip gets quite hot, After a few minutes, (about 5) the heatsink will be warm. If it is, you know you got it on right.
And thanks to Junits15, for telling me about using vaseline as a cheap thermal compound
