I am never going to lube fan bearings ever, same as I will never use again sleeve "bearings" of any kind ... just google user reported fan longevity of brands/models you like and I do and let's see for how long an "average user" (NOT the one who lubes bearings) enjoys them
S-FDB seems to live the longest while being very quiet (aka Scythe GT fans), then you have ball bearings (more noisy) with their long lifetime ... on the very end of that list are sleeve "bearings" the cheapest and crappiest of designs ... they die very quickly when compared to ball bearings or (S-)FDB ... I had sleeve fans on CPU heatsink (Xigmatek) before, it silently died when I was asleep, not fun to wake up in morning and see 90C+ temps on idle CPU - same goes with rads, my CPU (and GPU) life depends on it, I am not going to use el cheapo fans to save a few bucks and find them stalled or performing at half speed max when I need them most. my rig runs 24/7 and have always been no matter what parts are inside (they change over time), it's been many years like that, I need reliability for that.
by all means, keep lubing them, that is fine with me if it suits you, but it doesn't work for me LOL! if bearing starts stalling then it's done, unreliable, worn out and I replace it (e.g. in my car) or replace the whole fan assembly since it's relatively cheap ... and I don't want to spare my precious time on repeatedly fixing a $3-5 fan(s) every few months ...
I'm not going into discussion of locations of corporate factories around the globe, it's meaningless - what I meant it was the DESIGN (NIDEC) that matters most, not the factory assembling parts according to the design and specs (however that does matter to some extent too).
That being said we have a few Toyotas in family, and as long as they are Japanese designs (very reliable cars given proper maintenance since they are years 2000, 2002, etc.), the OEM/replacement parts come from Japan, Thailand, Canada and USA .. all that doesn't matter much as long as they are made to original Japanese specs
You don't have to agree with me, I don't have to agree with you, it's called democracy
to each its own!
A piece of advice if you run 24/7, and I do to. Get an Aquaero 5. Even the least expensive LT version will shut down your system w/ nothing more added than an inexpensive 12v relay if anything goes out of spec. From fans, to pumps, to just plain good old temps, it covers it all.
You're right, we're not going to change either person's mind. That wasn't the intent at all. Just expressing that your bad experience doesn't mirror everyone's experience. No doubt sleeve bushings aren't the best, but that doesn't make them a bad option either. I bought mine because they were the best spec fans I could get with a build I was running out of budget on. They are not a permanent solution for me. However, you made it sound like every sleeve bushed fan is going to fail in a matter of months. That is an exception, not the rule. If failure rates were as common as you imply, no one would ever buy them, including the OEM's that use them (sleeve bushing fans) all the time with little ill effect.
You take much liberty with what I said in exaggerations. There is no further maintenance aside from filling the oil well one time at the beginning of their service life. In case you missed it, that is the point of using a PTFE based lubricant entirely. My old home server is a perfect case in point, 4 yrs running a set of Yate Loon's, with no issue or extra maintenance. For the record, I toss any fan that gives me the first sign of trouble too.
To whit, I haven't seen any posts or articles complaining about these XSPC Xinrullian fans aside from yours. Google searches shows nothing that I have seen, aside from one person whose OEM pc had lost a fan, & not even the same model. Another claiming the the fans in OEM psu's were failing in 2003 (also without proof). So forgive me if I seem a little incredulous with an in absentia proof of failure, or performance being overstated, presented in a case you bring against these specific models. Without which, it is a moot point.
Consider the matter dropped. Good day sir, I truly wish you well in the new year.
