Hey guys, I’ve got a problem with using my RAM … I used the thermal tape to attach my heatsink on it yet it’s still very hot. Sigh … seems like my cooler doesn’t cool down the RAM properly. My card was almost ruined when I tried to remove the heatsink. Please help !!! Is there something like a thermal pad that can resolve this problem?

pressure, via spring-clips, to hold the heat spreaders on each side of the DIMM.
If you don't have mechanical mounting of your heat sink, and the thermal tape isn't working out, the other choice is thermal epoxy. Properly applied, it's a good bit better than thermal tape. It is, however, more or less permanent. That being said... just what are you doing that your RAM is in danger of being destroyed by heat? That would have to be not just a serious overclock, but a serious over-volting as well. -------------------- "Sometimes I can't tell the difference between thinking and being quiet, but I'll try."

Best thing to cool a ram? A cooperative ewe.
Note that for any cooling unit to be effective, a very close fit between it & the ICs is necessary. Including thermal compound of one type or another. Even a few hundredths of a millimeter space is enough to prevent proper heat flow. -------------------- Trouble rather the tiger in his lair, than the sage among his books.

Now i am using the AMD HD 6970 VGA card with a non-stock cooler. Besides of the heat dissipation, i am also looking for the product that can used for attach my heatsink onto the VGA RAM but not very sticky. Because i heard some one said when they remove the heatsink, the VGA RAM has peel off together, then the VGA was death.

a link to the card would be good .
the best method (all things considered) is to use thermal heat sink compound and mechanical mounting of the heat sinks . undo the clips, nuts and screws , etc and you can replace the ram chips easily . another method is a "thermally conductive adhesive" . the big boys use this stuff . it is not a very "strong" adhesive ... this will allow you to remove the heat sink by heating it above the normal operating temperature . -------------------- "Know how to solve every problem that has been solved"

ARTIC G-1 is a thermal glue that has higher heat dissipation rates than thermal pad and easier removal than thermal tape. Check out ARCTIC G-1 Thermal Glue
Hope that helps. |

If the heat sink is hot then it is getting heat from the RAM.
The heat sink needs a fan. |

How about something like either of these?

did you notice a lack of specifications for those heat sinks ?
sure , you can have a bunch of surface area but that is half the battle ... the interface between the component to be cooled and the heat sink itself is the other part of this story (airflow asides) . "sticky goo" is not always efficient in thermal transfer characteristics . you could wind up with the ram chips actually running hotter with a lousy thermal interface that just running in free air as-is . you might think that they are running cooler because you measure the temperature of the heat sink but in reality the chips are boiling . think about (albeit an extreme example) a pot holder ... you wrap the potholder around a cast iron skillet to pick it up because you just found out the handle was hotter than the hubs of hell . -------------------- "Know how to solve every problem that has been solved"

I use vaseline to conduct the heat to the heat sink from the device.
I did an experiment with the CPU in my desktop because the BIOS can show the temperature. No problems .CPU temperature was normal. The vaseline is liquid at the operating temperature but surface tension holds it in place even though it is in a tower computer.. It worked OK for a year then I changed to a new computer. |

think about it ...
if vaseline really actually worked as a solution to the transfer problem ... then why do all manufacturers use heat sink compounds ? obviously , vaseline is cheaper than heat sink compounds ... surely the bean counters would be happy as this would increase the bottom line . "It worked OK for a year then I changed to a new computer." think "long haul" . basically what you did was akin to the person that stuffs a differential full of sawdust to get rid of the "howl" of worn gears ... and then sells the car to someone else . -------------------- "Know how to solve every problem that has been solved"
