Introduction: How to Add a Heatsink to a Chip Without Mounts

Picture of How to Add a Heatsink to a Chip Without Mounts

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.

Materials:
-Vaseline / Petroleum jelly
-Sticky tack / mounting putty
-A computer heatsink, i got mine from a dead motherboard's GPU

Tools:
-Cotton swabs / Q-tips
-Your hands

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

I wonder if ordinary double sided tape would not also work? It's quite thin.

Believe it or not, a simple tiny drop of clear silicon (GE silicon II or whatever) or even 2 part epoxy (like JB Quickweld works great...just make sure you use a VERY thin layer, once bonded, they ain't coming off and thermal resistance is minimal (heat has to go thru the plastic case anyway) if you use a thin layer.

Can I use thermal paste instead. I bought stuff to make my desktop as I want it and proccessor is kinda expensive so I don't want to risk burning it :)

You could use thermal paste in place of the petroleum jelly for sure. Aside from that, you could consider a thermal adhesive to mount the heatsink

Heh, I remember when I was 14 years old and superglued heatsinks on my graphics card, Riva TNT2, replacing main heatsink. It worked... For about 4 seconds. Awful smoke came out and I was taught two important lessons:
#1. Superglue melts when exposed to heat and makes it impossible to remove the all glued up video card from motherboard without breaking both.
#2. Use causion or protective gloves while handling melted glue... That was the day I became a cyborg...
Great tip using vaseline by the way!

im sorry it took me so long to post back buti lost the notification of this comment amongst all the others :s

i actually have a riva tnt2 agp card, its rather useless since every system ive plugged it into refuses to send video through it for some reason even though the card is fully functional :P

yea if anything i would probably try some sort of epoxy like jb weld or the sort and see how well that would work if you really wanted the 'sink to stick.

why the vaseline?

zack247 (author)sharlston2010-12-09

it acts as a thermal conductor between the surface of the chip and the bottom of the heatsink. without it the heatsink would not be very effective, you could use some thermal paste / thermal compound, but vaseline works just as well.
