bare naked RAM is better, and adding a fan to blow around it will definitely much better

somehow i am still sceptical about the heat transfer provided by thermal tapes. i don't see how well it does the job.... doesn't look like it can absorb the amount of heat and transfer it to the heatspreader effectively.

heatspreader will be very efficient if there weren't any thermal tape used, and the heatspeader touches the chips directly... just like a heatsink on a cpu.
