View Full Version : Superglue! yuck!
#1- Let's see my vid card is running a littler hotter than I like, hey! got some nice sinks I salvaged here in my junk box. Let's put em on. Dab of asII in the middle, drop of superglue on the corners of chip. Bingo! Dang, It stills runs hotter than I like, guess I will order those sterling silver sinks from stuffIwannabuy.com. Now let's just pop these others off. CRAAAACCCKK! SONOFA!
#2- Well, got em off without breaking anything, what I got here?
Looks like a dab of asII in the middle and some raised superglue dots on the corners. RAISED dots! Run your fingernail over the glue and see how if you can feel it.
The point is I don't like gluing sinks, fans, etc on. Pretty much when you glue it,it's there for a long time. Also for max heat transfer, max surface area should be contacted. Ever taken any glued sinks off? They are minutely raised off the surface of the chip by the adhesve. Plus you didn't get the thermal compound over the FULL surface of the chip.
Max contact = good
I have used various methods, one of which is some tiny wire ties to hold the sink on. Will post some pics this weekend when I take the puter down. Any thoughts?
:eek:

what about artic silver epoxy?
I haven't tried the epoxy, but it is still introducing a substance other than the thermal compound. Is epoxy a good thermal compound? Doubt it. The epoxy is even stronger than the glue so you better hope that neat little fan/sink doesn't stop and need replacement. When you glue something on better be sure it is the best solution as it does not lend itself to replacement/experimenting very well. I prefer, when applying sinks, etc., to have the absolute best contact I can get. If I put a sink on a vcard ramchip,etc. I lap and get the best contact possible. I don't want ANY space if possible between my chip and my sink. Would you glue a sink on your cpu?:D
I love zip ties! :D
Take the sink and make slots for the zip tie and pull dang tight works great for sinking ram anyway!

Arctic Silver Epoxy is thermal adhesive. The epoxy is part of the thermal material. It's not quite as good as straight Arctic Silver, but it's better than superglue in most of the cases I've seen. Agreed on the 'make sure it's what you want before glueing it down' comment. Also, do you lap your heatsink only, or heatsink and GPU? I'd think a bit of sanding would take care of the raised sections that had glue on them, and I've heard that a lot of GPUs aren't anywhere near perfectly flat as well...

I've had good success with the Arctic Silver epoxy. This stuff comes in two tubes that you mix and is permanent. Some of our members claim that if you mix 1 part each of the two epoxy mixes and 1 part regular Arctic Silver (1/3 each), that this is ideal and sometimes you might actually be able to remove the sink at some point in the future.
I lap all my sinks, but not necessarily to a mirror finish. If you start sanding on one I bet you will find there are not many that are flat. I just go until I get an even surface across the sink and then slick it up a little. My ram chips and gpu , northbridge, etc., I just use some 1200 grit and get them smooth.(unless they are really bad). I am not looking for glasslike smoothness, just smoother than it comes. Re: thermal adhesive, I am sure it is better than just epoxy but it is still "stuck on". How thick a layer are you using? It will still raise the sink above the chip even if minutely. I prefer a mechanical connection ie: some type of clamping device. Granted we are talking about a small amount of space between the chip and sink but remember: Every little bit helps! If you go to great pains getting your cpu cool, why skimp on your other chip cooling? After all that's what you are trying to accomplish in the first place putting extra cooling to it.;)
Most newe boards have special considerations for the chipset. They usually have 2 pins holding the heatsink to the northbridge. so that takes care of that portion. Like I said zip ties work great for mounting ram sinks. Go around the outside with two longer zip ties pulled together. workes great for me and they are snug. get thin ones though. you usually have to make grooves in the edges of the sinks though.
And as for GPU's the newer cards usually have some type of mounting holes you can use to mount heatsinks or fan sinks on them. Then in all cases you can use your AS2 without having to worry about the epoxy raising problem.

Yep, I have a geforce 2 ultra and it has holes at both ends of the ram and about 6 or so holes around the gpu. Remember wire ties can be your friend!
You could try 3M Thermal Tape. Not as good as ASII or Thermal Epoxy, but it'd get the job done, and its not permanent or messy.
Good point! The 3M tape will work as well.
Oh, BTW those wire ties....be very careful. Don't let them touch anything they shouldn't. Otherwise say chio to your hardware. ;)
That's why I use the plastic ties myself.

I use plastic ties,guess it sounded like "breadwrapper ties" I just call them wire ties. A point I am trying to make is if you are gonna work your butt off to get a few degrees off that cpu, then why not use a few of the basic things you learned with that to cool the rest. How much more did that cpu cost than that geforce 3?

Are you going low budget to make a point, to keep your coins or are you not aware that there are vid card hsfs that attach to the card through those holes. All of the fasteners come with the fan.
AS Thermal Epoxy is your best bet to stick the RAM sinks on. No ifs & buts about it. A lot of people forget that you actually need a good deal of pressure if your attaching the sinks with a clamp. The plastic ties will not get anywere near the pressure that you nead. AS Thermal Epoxy is designed exactly for this purpose. Even the super glue on the corners & ASII in the middle will give poor results compared to normal metal epoxy mixed with an equal amount of ASII.

yeah, but making an old 496 fan into a nice Geforce2 fan is fun....ill never buyt an orb....never.....

Actually, I am going to get one of those nice copper coolers. I am just presenting some alternatives to some of the fastening methods I read about. Also, not everyone can afford new stuff and probably has some old fan and sink lying around. I agree wire ties are not the best, but if that's all you got it's better than superglueing them on. I would just hate to see someone ruin their northbridge or graphics card ripping off a glued on item.

Ram sinks I could see, but glueing a blorb on your gpu I couldn't.
Just wanted to get this back up front since I put a pic on. (thread, look ma no glue). Yeah I know, I didn't use wire ties. (but I have!)
I know, I know I should have posted pic on reply to this stead of a new thread. Thought about it when I hit "submit" key. :eek:
At least I didn't delete camera yet.
