zomg:eek:

If you already have as5, what I would do is put a small amount of as5 on the chip, and push the heat sink down hard, turn it slightly, and lift it off. Make sure everything is coated but the outer perimeter of the chip. Then, use a small, small, amount of super glue and apply pressure to the ram sink until it sets up.

If you decided to go with an AS epoxy, remember, very thin on that shit y0!

Don't get the shit in your eyes, and make sure you got some goof-off near by in case you get too much on whatever you are doing. The shit is conductive.
 
Did you apply some pressure for a few seconds when putting them on? Those Enzotech's ramsink have really good thermal tape on it (3M), but you need to hold it for 30 seconds with some pressure to let it stick. I just recently took mine off and nearly bent all the pins from trying to nudge it off. Believe me It sticks like a mofo if you get it on right.
 
Really AS5 and some super glue will work? I have plenty of it. So I can put it on all of the GPU ram and mosfets? Do i remove the white thermal adhesive tape thats on the Ram/Mosfet sinks right now?

Ill check to see if they have become more sticky. I pressed them really really hard for a long time and they still seemed easy to take off. Would warming them before sticking them on be better?
 
Yes, you need to remove the tape. And clean the surface afterwards.

No, AS5 is not an adhesive. They make varieties that are. You should get one of those.
 
Thermal Tape + TIM = ruined tape.

Yes, if you decide to go with TIM, remove the tape completely.

My experience with thermal tape is that is does need some curing time provided the part STAYS ON while it's trying to cure. Once it's cured, it's a pain to ever remove it. It sticks that well.

Also, make sure that the ram, mosfets, etc. is COMPLETELY clean, even from finger oil when working with thermal tape.
 
what does TIM stand for exactly?

(So basically what im getting out of this is either buy the AS Adhesive, or press really hard and let them sit a while to cure.
 
TIM = Thermal Interface Material

Just dab the tiniest dot of AS5 on each of the ramsinks, then dab the tinest bit of superglue on two of the corners and stick it on. To remove the ramsinks just twist them, but if you use the epoxy TIM, they'll stay on forever.

Your choice.
 
I like to mix a 60/40 of AS5 and the AS adhesive..... the 40% adhesive is enough to keep the sinks stuck....but not enough where they get stuck permenantly...usually they pop right off with a twist.

You can do this if you want, but you really shouldn't. The AS epoxy isn't the strength it is for giggles. Doing this sort of thing will substantially weaken it. Improvising with superglue is also not really a great idea.

AS epoxy can usually be removed with a hair dryer, gentle twisting, and some patience. The epoxy is very strong when used properly, but has very little way to resist torque. It's amazingly weak when you combine this principle with a little dry heat.

ive done the mixture on over 100 ram sinks.... it works perfectly.
 
Improvising with superglue isn't generally a great idea? News to me since it is generally the easiest and most effective way to stick on ramsinks in price, and cooling, because AS5 blows the epoxy out of the water.

Except when it falls off and fries your card.

I'm not saying that it'll never work. It's just a bad idea given that it's being recommended to people that don't know AS5 has no adhesive properties, and that you can easily remove the actual epoxy once you know how. Likewise, the superglue technique gives a more brittle bond and relies on proper execution of the technique to avoid a nasty surprise.

Moonshine's great fun until it turns out you made methanol instead of ethanol. Same issue here.

Its not that it "might work". It ALWAYS works. Its not like ive done it once. Ive done it on over 100 sinks... In fact ive done it on over 200 sinks...perfecting the %....during the 1st 100...when i used less epoxy some did fall off, and they never once, "fried" a card, or a mobo.

And its the best of both worlds, becuase the AS5 has much better themal props than the epoxy.... and the orginal OP gets to benefit from my testing.... and i dont have to use a hair dryer....

try either quoting my WHOLE post, or reading the whole post...

the 60/40 mix ALWAYS worked... in fact 65/35 ALWAYS worked too... i only got the occassional falling sink at 70/30....but at 60/40, it ALWAYS worked...but I always reccommend 60/40 just to be safe.

JUST like I said in my post.

Nah, I think just quoting the parts where you contradict yourself and demonstrate my point was sufficient. The rest of it is just above, why pollute?

Anyway, I'm not interested in arguing it. Obviously it works fine for you. I just don't see any reason why anyone doing their first ramsink application should be trying it when there's a more reliable method at hand, or any justification for recommending it.

And theres the beauty of it, i DIDN'T contradict myself...

if you actually read it, you would see, I said it ALWAYS worked at 60/40.....

but of course, that didn't work for your reather innefficient arguement....

In fact the 60/40 method is much better than "your method"

1. Better thermal properties than your method.
2. Dont need to use a hair dryer to remove it, a simple twist will do.
3. Wont need to try and get off that epoxy, which is a pain in the butt, the 60/40 method cleans up much nicer.


The 60/40 is much better than pure epoxy in every way.
 
the first time i met my girlfriends uncle he offered me moonshine from a jar and i turned him down cause that week in pharmacy school they told us it makes you blind. anyway i'm curious about this also since i want to get an accelero s1 for my 8800gt. ultimately what is the generally accepted best way to get the ramsinks on?
 
If you don't want to improvise:

http://www.newegg.com/Product/Product.aspx?Item=N82E16835100005

The two more common alternatives are using an improper mix of the above, or using non-adhesive thermal grease + superglue as detailed above. The first is usually done to make the ramsinks easier to remove later (pointless IMO since they can already be removed easily). The second has the advantage of giving somewhat better heat transfer, but relies on proper application and uses an adhesive that is less suited to the application (as above, I don't think this trade-off is worth it, and you have to be careful to apply the right amount of AS5).

Note: usually they come with preinstalled thermal tape. For some reason they like to sell the ramsinks with this stuff attached, even though it often can't hold on for shit. You'll need to thoroughly clean this off before attempting any of the above.
 
Well I just realized now that sticking shouldnt be a problem in regards to falling off. Its more of an issue with full contact and heat transfer. See I have a Lian Li 1200 case so my motherboard and all components are upside-down from a normal tower setup. So that means my GPU ramsinks/mosfet coolers will be facing up, no risk of them falling off, gravity will keep them right where they should be. So does this mean its the perfect situation for simply using AS5 and AS5 only? It would provide a perfect seal between the cooler and the chip and theres no risk of coming off. This is a good plan right?
 
In general distilling grain alcohol to make moonshine isnt deadly. It got its bad rap from the old days when people would pour whatever into it to give it more "kick" since that was the "in" thing back then. Gasoline, methanol, rubbing alcohol, bleach, whatever would give it more "kick". That and using lead containers, pipes, and coils to distill it.
While it is legal to make your own wine or beer in our country, distilling alcohol is illegal both because of the bad rap it got with the earlier idiots, and because its explosive. Also any bad stuff that does happen to get formed, gets distilled as well. Wine is idiot proof. Screw up bad with moonshine and you very well can end up blind.
Yes you can get methanol in your moonshine and it does still happen, but its not the norm.

Anywho: http://en.wikipedia.org/wiki/Moonshine


Now that the history lesson is over :D
If your ram sinks fall off during operation, they would only get hot enough to burn up if doing something like, oh... intense 3d gaming. If your ram is spazzing out during intense gaming you will likely note the massive artifacts appearing all over the place long before the ram will toast.

It always works here as well, though I use Alumina adhesive with equal part Ceramique to keep it non-capacitive around traces. Decent hold and comes right off when I want it to, also faster and easier to clean as you said. If I didn't already have the adhesive, I'd use the superglue method though.
