For less than $100 each I'm set for nearly a decade.ĬPU and gfx card now that affects fps and is over $1000, actually the most important part to me. PSU and MB are insignificant to me and I can blindly pick one by reviewing user comments from newegg in about 5 min, and it will last for years. I disagree with the importance you place on this and all of the references you made to this being crucial knowledge. I can't even read all of the chapter titles in this article. The lubricant in FDB fans is pumped up to the whole surface of the bearing through a spiral groove, and this feature makes these fans a better choice for horizontal mounting, since the lubricant covers the whole surface of the shaft in all cases.ġ6589602 said: I'm glad there are people dedicated to this but I'm not. This means friction is kept at very low levels even after prolonged usage, which can easily exceed 50,000 hours and in some cases reach up to 300,000 hours. Fluid Dynamic And Hydro Dynamic Bearing Fansįluid dynamic bearing (FDB) and hydro dynamic bearing (HDB) fans are in essence highly modified versions of the sleeve bearing fans, where the design of the bearing is different and also the lubricant fluid is kept intact with the use of seals (some good-quality sleeve bearing fans also feature seals to keep the oil intact). Some manufacturers use magnets in order to keep the shaft balanced on all cases and avoid this issue. In general, ball bearing fans have an increased noise output compared to sleeve and fluid dynamic fans, especially at low speeds, when the rotor assembly balance can be affected. In the last photo, the two ball bearing rings are depicted. They can become annoying at this point, so users will probably change them long before they completely break down.Ī quality double ball bearing fan by ADDA. But in most cases, long before the fan stops working, its bearings will start to produce increased noise due to wear. The typical lifespan of a good ball bearing fan can reach, and in some cases even exceed, 50,000 hours at very high ambient temperatures. This is in contrast to the sleeve bearing fans, which are seriously affected when they are mounted horizontally, as is typically the case with PSUs. This type of fan can be mounted in any orientation without affecting its longevity. Higher-quality fans use double ball bearings to reduce friction. Sleeve bearing fans aren't designed for horizontal mounting since oil inside the bearing moves to one of the shaft's sides, so it doesn't provide uniform friction protection. Their major advantage is an affordable price, which makes them popular in low-cost PSUs. After-sales services are available on select models.Good sleeve bearing fans can last up to 30,000 hours (and even more in some cases) at temperatures reaching 50 degrees C.
