| Cheap ways to attach chipset heatsink? |
| (1/3) > >> |
| Tiger-Heli:
Here's the deal: I have a 16M TNT2 AGP card with a dead fan that should be sufficient for how I use the computer. I have a northbridge heatsink from a dead mobo that will cover the chip. I have Arctic Silver Paste to use between the chip and the heatsink. Question: How do I hold the heatsink to the chip? There are no good places for drilling holes and using plastic clips. I know there's Arctic Silver Adhesive, and/or Frag Tape, but I can't find it locally. I could order it for about $10/15 (with shipping), but considering a refurb Radeon 64M is $20-$25 from www.newegg.com, this is not a cost-effective option. It looks like I can glop some glue outside the corners of the chip and hold it on. (good places on the PCB for this). I am considering the following options: Wellbond wood glue from Home Depot, should work, but is pretty much a permanent attachment, if that matters??? DAP adhesive caulk (like holds bathroom sinks in), should work. My wife's hot glue gun and glue - if I can find it and get it to work without dripping glue through the arctic silver, never used one before. Clear Silicone Adhesive - should work, but I would have to buy this ($4) Any recommendations on which way to go, other options??? |

Dont' use anything not ment to be used. it will do one of the following. 1) not stick under heat. 2) not transfer the heat well... (really) 3) be conductive and blow your chip 4) eat away at the chip. Instead... try and find another way... If there is a heat sync on it, try pressing some of the metal 'fingers' of the heat sync together, and screw the fan into these. this is what I did and it worked great! |

And TNT's don't get extrememely hot. The heatsink will overlap the chip and the glue will not go on the chip but outside the corners of it between the PCB and the sink, so . . 1) Kinda a concern, but the silicone at least should be high temp stuff. 2) Doesn't matter, the artic silver transfers the heat, the glue just holds the sink in place. 3) I don't think the items I mentioned are conductive and it won't be directly on the chip, but otherwise, that could be bad. 4) That could be bad also :-( So . . . |

I wouldn't do that if I were you... I know Arctic Silver. It's supposed to be applied in a razor thin layer, and then the heatsink is supposed to be held to the chip surface tightly using springs. If you spread the Silver compound on the chip, and then apply superglue to hold it on, you'll probably end up with a small gap between the compound and the heatsink. (and you won't be able to easily try again.) If you apply the Silver compound thickly, I don't think it will transfer heat as well. But I haven't tried it that way. If the chip had a graphics card heatsink with a fan on it before and the fan blew out, I don't recommend using a chipset heatsink with no fan. You should just get a new fan, they're usually pretty standard, and screw in to the heatsink fins just like Lilwolf said. Or you can just aim a fan at it from somewhere on the case. |
