Corsair attacks OCZ heat spreader claims
 

Once you remove the heat spreaders on both Corsair's and OCZs memory modules you will barely hurt your memory performance and its overclockability.

look at G.Skill which shipped without and performed on par/better than the rest:)

Some products are designed to make people feel good; look good; smell good. As long as you are happy you live longer and healthier. I am glad the heatspreaders are making people live longer:)

I think, the biggest advantage is that the modules are less flimsy.

My Kingston Modules where hard to push in the slots, I almost felt like they would break.
