Kingston came to the market with the KHX-FAN with hopes of adding additional cooling to their memory lineup. While the design borrows some ideas, it incorporates a few of its own. The huge flood of blue LED's is one thing, I have seen others in action and the Kingston memory cooler has by far the brightest LED's. While the KHX-FAN isn't black as most on the market would probably prefer, blue is my personal second choice and Kingston's blue is a fine shade to use.
This cooler not only offers what to me is a sexy looking cooler, with bold lighting, it also offers a seven degree drop in temperatures in a critical and usually overlooked component in the PC. I have been cooling my RAM since the DDR PC3200 days, due to a propensity to overclocking, and have continued to cool them ever since as I tend to punish my memory pretty hard. Kingston seems to offer the total package of lighting, cooling, sexiness and a competitive price of just $23 dollars and I'm having a real hard time finding reasons not to buy the KHX-FAN from Kingston.
I did run into one snag; the height of the KHX-FAN blocking the CPU coolers intake. Now this isn't such a problem with 120mm coolers, as they tend to sit a bit higher off the motherboard than my Noctua cooler, so the issue isn't as pronounced then. Secondly, a lot of us who tend to abuse our hardware a bit more than most, we have the option to water cool the CPU and then the fan has all the real estate it needs with no effect to the CPU. As I mentioned before, this height issue plays to your favor if your RAM has the taller spreaders, as the KHX-FAN will allow for most of the tallest heatspreaders.
