In some extreme cases, ram coolers might help during maximum oc. For 99.9% of the time, I see heatspreaders on ram about as necessary as big cooling fins attached to usb slots. Removing the top fin off the tridents makes little to no difference since it doesn't remove the entire heatsink if you were concerned about it. Just the taller than normal fin area. What remains are the typical heatsinks along the sides found on low profile ram actually in contact with the ic chips. I have a feeling all the multicolor, various fin designs were more or less marketing hype/gimmicks. Plain ram is harder to sell than uber turbo l33t racing ram. Just like motherboards are focused on the 'bling', they're no longer plain boring green - they have all different shades of anodized aluminum heatsinks with heatpipes and water cooling ports, light up logos, light up led trace paths on the audio, pcb's come in every color just about, there's even a motherboard out with a sort of shield over all the components (can't be ideal for passive cooling) with arctic camo all over it. Granted vrm's can get hot while overclocking, but it's pretty easy to tell. Carefully touch your finger to any number of components, vrm's get hot, northbridge on older boards gets hot, southbridge gets a little warm - beyond that, I've never felt hot ram.
