Keeping your modern machine cool can be a challenge these days with 16GB of Memory and a 4GHz Processor

This cooler, with a single, centrally located fan, does not provide effective cooling to the lower and upper (first and last) memory modules on the RAMM stick because the non vented (cheap manufacturing process) metal brackets that attach to the memory slots block the ends, thus inhibiting air from flowing out and away from heat retaining memory slots

It's relatively quiet; and keeps my overclocked memory nice & cool.

So you probably won't need this if you have decent cooling in your case
