they have the thick jelly insulator between the cooler and the heatsink. where can i get more info about them? What are they called? How can i clean it? Is bubble gum better?

1st - who or what has jelly?
2nd - between the COOLER and HEATSINK? I believe that two words describe the same object.
3rd - what cooler/heatsink?
4th - Name/brand of the product.


?are you referring to thermal paste, thermal compound, goop, thermal interface, thermal tape?

Thermal paste?

they just help transfer heat

those jelly things between the video card memory and the cooler. some of the mother boards have it too

don't know what they are made of, but it is called a thermal pad.It is the worst way to couple the CPU to the heat sink thermally. Just use white silicone past,
unless you are over clocking, and need the extra 2 or 3 degrees you gain from the expensive ones like Arctic Silver.

what can i substitute it for? if i remove it, there is a huge gap between them

be careful with it. Just put another thermal pad (3M is the best). If you use normal liquid thermal interface or nothing you might have a little electrical discharge on the chips since they have no heat spreaders and they are very sensible to discharges. Don't f*** up the card.

im getting bad overclocks with this cards memory. there are no after market cooling for it so i have to find ways to make this work. how abvout a copper coin or a flatted copper tube?

discharge wise that would be the same as putting it on bare, thermally the coin would have to have a mirror finish on both sides to even have a prayer of working.I wouldn't even consider it.

Edit:Even a mirror finish has thousands of microscopic holes and scratches, that is what the past or pad is for.

It's not an insulator it's a conductor.

No offense but if you have no idea what you're doing it'd be best to leave it alone, those memory chips are VERY sensitive to pressure, I ruined a 9800pro AIW trying to put on new heatsinks about a year back.

oh lord.

Conductor - transfers heat.
Insulator - Keeps heat (or cold) from getting away.

Try checking your air flow in your case. If you have better air flow your video card will cool better. Unless you know what your doing I would not mess with the factory installed pads.

BTW what kind of video card are we talking about here :?:

my x1950pro have those jelly pads too, and also the crazycool back plate of the gigabyte board.

and my case is thermaltake armor series with the 250mm side panel fan
