Happy New Years everyone!

better go with Swiftech Helix (some magical Z-bearing, hell knows what that is) or just get Scythe GT Ap-15 1,850rpm with Sony Fluid Dynamic Bearings (lasts forever) and be done with it!
I'm a little drunk so bear with me.
Sleeves are fine in a vertical orientation, and as long as you lube them well (I use Tri-Flow teflon light oil), sleeve bearings will last a good while horizontally mounted. Sure, they aren't ball bearing or whatever black magic fluid suspension method is currently in vogue. Although sleeve bushings are technically fluid (oil) suspension types too. However, they certainly don't seem loud to me. But then, I've ran 38mm Delta's/Mechatronics/etc many times in the past. That's subjective opinion though. They don't bother me a bit, & the Aquaero throttles them down very nicely at idle. At 50% fan rpm, the MCP-35X on my AD II is far, far louder even @ 15% of it's rated rpm. That said, I'd rather hear the fans than the high rpm ddc pump any day.
As for the durability: Idk yet, I'll get back to you on that one. Xinrulian makes quite a bit of fans, not just sleeve bushings (which is what they really are) models. Although the ones that XSPC markets are, the company that manufacture's them from makes many different models, and not just geared towards computers.
As far as the specs, Ehume seems to think the world of them, and claims rated specs are accurate. Although he didn't test the static pressure rating, they do quite well according to him, outperforming the AP-15 for a pittance.
Not to mention they are pulling fine through my UT-60 right now, a rad with very high tube density & 9.6 FPI density. Finally, if they do in fact kick off, my Aquaero will auto shutdown the system while giving me a nice alarm for a warning. I still have a box full of Mechatronics BB 150 cfm 120 x 38's to back them up, just in case. Although, I really prefer the quiet environment that doesn't sound like a shopvac... No harm, no foul.
