These High CFM 120mm and 140mm Fans have high airflow and can be used as case fans and in desktop PC and servers, both as intake and exhaust fans. Ultimately, the option you choose depends on how the fans are plugged into the motherboard. Since i dont have a fan controller on my case, and my fans are running a bit to slow. Notice that the power load for the low speed fan motor passes through a resistor. About Lenovo + About Lenovo. DC is for Direct Current (or Continuous Current), distinguishing it from AC, which is for Alternating Current. Thanks again. Ceiling fan speed control switches are usually wired such that the switching sequence runs Off - High - medium - Low - Off, so that the fan starts up with the full-speed capacitance to get it going. I have seen two different kinds of regulators in my life. I owned the 4790K and had it OC to 4.7Ghz at 1.225V and with my 280 AIO temps where around 65-70C during gaming even in GTA5 which pushed the CPU to 60-75% usage. Most commercially available variable speed fan controllers on the market are not designed to handle the heavy loads that come with a fan like the Lincoln Mark VIII. Just seems like crazy high temps with a water cooler, i mean at stock he should not be seeing those temps unless he was using the stock heatsink which was crap. Fans produce air flows with high volume and low pressure (although higher than ambient pressure), as opposed to compressors which produce high pressures at a comparatively low volume. REPEAT the self-test. View solution in original post. It has 2 speeds: Low speed is 60% and high speed is 100%.
