Before trying the SK6 I was using a large aluminum Taisol heatsink with a quiet low rpm fan. This would keep temperatures in the 40's with the 1.2 GHZ cpu running at default, but simply couldn't handle the increased voltage and heat that came from overclocking. I knew that a higher output fan would only be a stopgap solution on the Taisol. FANS: The SK6 came with a Delta 8000 rpm/50 CFM fan(see pic below) that was very loud. I could here it upstairs. I ran the benchmarks using that fan. The fan requires a 3 to 4 pin power connector. I forgot to use the adapter the first time and had to reset my CMOS!

These fans will burn out a motherboard fan header very quickly. These fans can also shred fingers so be very careful if you have any small people in your house. Installation: The SK6 uses a standard two slot clip which attached to the center posts on the CPU housing. A screwdriver is a must to get enough tension on the spring to fasten the clamp. The clip is asymmetrical, so if you put it in the wrong way, you will get very poor contact with the CPU. The fan is held on by a very simple and effective system, two wire spring clamps that hook on the heatsink and then snap over the fan. This is much easier than screws and makes it simple to swap fans.
