I'm at a toss up between these two coolers. I do plan to try some overclocking and have no idea which would suit me better. I also don't want something super loud, but i expect some noise to cool the processor. I like the fact hte big typhoon comes with a fan, but i would just purchase one if i decide to go with the Sl-120. Any advice is appreciated. Also, will i notice a big difference between these and the stock opteron heatsinks with the heatpipes when overclocking? -Rob
