HELP!! What is the best product for cooling a RAM?
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?

hello hang19840324!

these are my suggestions:

the ram heat sinks work best with good air ventilation in your cpu case.

the thermal tape used on ram heat sinks were purposely made difficult to remove. they're for permanent attachment purposes. the thermal tape is specially manufactured to efficiently transfer the direct heat from the ram chips to the heat sink. then its up to the air cooling in your case to dissipate the heat.

Is your ram heat sink like this:

Or are they more like "heat spreaders"

while there isnt much to be very technically correct on the topic of ram heatsink or heat spreaders, they both have the same idea of trying to conduct the heat from the ram chips, and spread them out and further using the corrugated design of the sinks.

again, ram heat sinks or ram heat spreaders will work best when you have good cpu air flow.

**In my experience so far, we've encountered few defective ram chips -- our desktops and laptops take a good amount of abuse and heat. ive encountered a burnt processor due to a malfunctioned cpu fan, but ive not had any defective ram chips due to overheat/burning. the ram chips that gave out and had to be replaced were due to electrical problems (a curious case of a strong lightning-thunder strike and sudden power fluctuation that killed the desktop's motherboard and ram.)

Shown below is the ideal cooling and air flow for cpu cases. The front of the case may have airflow vents, next to it would be a fan for intake -- sucking cool air from outside of the cpu, and blowing it inside the cpu case.
the first passage of the cool air would be the hard disks, and then on to the ram chips, and then to be further blown and circulated by the processor fans. at the back of the cpu should be an exhaust fan.

It is becoming more common on cpu case designs to include more intake and exhaust vents.
Notice the side fan on the removal panel. The side fan is set as intake to suck cool air from the side of the case and blow it to the cpu processor, ram chips, and video card. The top exhaust vents also contribute to even better airflow.

Of course, having more air vents in the cpu case will suck in more dust and dirt to the cpu. dust filters that come with cooling fans/ cpu cases work best in this scenario. and finally its a good idea to set a schedule to dust and vacuum the cpu innards :)

good luck, and happy gaming :)

Thanks for your detail advice! Now i am using the AMD HD 6970 with a non-stock cooler. I know the fan can solve my problem, but i am still looking for a product that can attach my heatsink on the the VGA RAM but not very sticky, because someone said when they are removing the heatsink, the RAM will peel off together, sound easy to damage my VGA board.

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