i know its an easy way to hold down ramsinks and such.
but when it comes time to take them off(for whatever reason) will any electronics come with it? i dont think the bond is that strong. is it?

i just use super glue. hot glue seems like it would be too messy to control
Uhmm.. Hot glue melts when it gets warm.. hint hint?
With a bit of heat you'll get 99% of it off. Just heat up, wipe off with a old credit card.
That darn last 1% isn't worth quibbling about.

exactly my thinking... how are you using hot glue to secure ramsinks?

:confused Hot glue is a plastic (insulator) and I would think that it would insulate the ram from the sinks?!? (If it dosent melt off first)

I woudn't use hot glue.
I would use arctic ALUMINA epoxy, with some AA or AS in there to dillute it, so that you can get it off later.

I agree with this 100%. If getting it off is important dilute it like funk said. This is probably the best stuff to use as opposed to hot glue because you know your bonding the stuff with a proper heat transfering material. I wouldnt trust hot glue on my card.
Although I dont recommend diluting it with AS, use AA, because any AS that gets on any traces may cause the card to short out.

i dilluted with AS on my GPU, but yes, dillute with AA on ram.

lol, are you serious?

I use silicone sealer because it sticks better than thermal tape (I'm afraid to pry off any heatsink attached with it) and decreased the temperature drop between my graphics chip and its heatsink by 1.5C. But the heatsink can be can be removed by slicing through with a razor, and it can take temperatures of up to something like 200-250C.

well the hot glue does work...i just put a dab of hot glue on each side to keep it there...the sinks stay on like a charm and temps are way down...
the question was.....
When pulling the excess glue off after you remove the heatsink, will it pull electronics with it?
and for the others...it takes 80c to melt the glue...and around the core and around the memory chips, it only gets to like 26c max.

only thing ive used hot glue for is to hold vid cards from comming off mobo

I hope you use some AS or something aswell...

Heat it up before you yank it off. Then peel off as much glue as you can using your fingers or plastic tools or toothpick. To remove more glue, heat it up wipe it off.

Just curious:
How do you know that temps are down?
And where do you get the data for max temps on mem and core?

Just spray or pour isopropyl alcohol on the glue and board and it will peel right off. (I do this all the time at work.) It dries quickly too. I'd put the board in front of a fan for ten minutes or so though, to allow the alcohol that gets underneath components to get dried out.
Be sure to use alcohol without additives. (like wintergreen oil)
The alcohol just breaks the adhesion though. If the glue has gotten wrapped around something, it can still be a problem to get off.

I used Artic Alumina and it worked really well. its only like six bucks online or something

The whole purpose of installing heatsinks of any kind is for heat dissipation...primarily. So how do you figure hot glue is a good thermal conductor? Isn't hot glue plastic/rubber compound? Those are bad thermal conductors. I'd never think of using that on electronic parts.

hot glue....better off using a chunk of the sole on your sneaker

man you guys dont think do you....geesh..
for thermal paste im using AS alumina and the hot glue is put along the sides to hold it there.
you were thinking i was using hot glue as thermal paste? :eek: :eek: :eek: :rolleyes:
the sinks are on solid and can be pulled off if necessary for selling or RMA purposes

If your vid ram doesn't get that hot, then sure, hot glue will work. It will be easiest if you just tack it in the corners, prefferably on flat circuit board (no components there).

That makes a bit more sense thank you for the clear up I thought you where crazy or something.

Well guys I repaired a laptop that was rendered dead by a local PC shop. I had to use a hot glue gun to repair the power input in the back so I gobbed it on a WHHAALLLLAA, it's still rockin 6 months later after I sold it for 350 BUX!!!!!!!So as far as strength goes it's decent and when it comes off it releases like a mold without damage to the board. Maybe a luke warm haiedryer to soften it a bit. The heat from the laptop doesn't seem to loosen it either.

of you can supercool it with an upside down can of compressed air. that causes it to shrink and get brittle. it just falls off. try it. put some glue on a table. spray it with the liquid from the compressed air can. it just comes off the table

Yeah, good idea! :)
It works with chewing gum of carpet, it will work with hotglue, cause both are a bit rubbery.
I would go for this idea since I got the spray.
