In order to test for the benefits of this cooler, I attached a temp sensor to my ram's heatspreader and did some ram-stressing benchmarking using Prime95. The ram I am using is OCZ XMP Extreme Series DDR3 1333 2x2gb overclocked to 1600mhz. After 10 minutes of stress, the ram had reached 51c at the sensor when the cooler was off. When the XTC was given 50% fanspeed, the temp quickly dropped to 44c. Then when I gave it 100%, the temperature at the sensor dropped to 36c. No doubt that the cooler does it's job, and makes it a valuable tool to the serious overclocker.
In closing, I have to say OCZ did overclockers a favor when revising their classic ramcooler design. With added function: speed selector switch, form: taller mounting, and looks: black brushed aluminum, this revision brings the old design up to speed. Seeing a significant temperature drop makes me sleep better at night, and this cooler is welcome in my case anytime. Although I had an issue with the non-adjustable mounting bracket, I would still suggest the OCZ XTC ramcooler to fight high memory temperatures, just be especially careful with the installation.
