CXM has a sleeve-bearing fan and the Vengeance has a ball.

SO it's just as great of a choice as a seasonic prime?

Wait, the CXM series is tier 1 other than the fan/multiple vs. single rails? How does a fan and only a single rail knock a PSU down from Tier 1 to Tier 3?

How do you even grade these things?

  Hide contents

Quality and electrical performance. Value means nothing. No brand biases. Features don't matter.

 

Any unit with a sleeve-bearing fan will be deemed no better than Tier 3.

 

Solve your own audio issues  |  First Steps with RPi 3  |  Humidity & Condensation  |  Sleep & Hibernation  |  Overclocking RAM  |  Making Backups  |  Displays  |  4K / 8K / 16K / etc.  |  Do I need 80+ Platinum?

If you can read this you're using the wrong theme.  You can change it at the bottom.

Well hopefully someone who actually does the rating of these can reply to that :P  I just wanted to point out that point about why the bad fan knocks it down to no higher than Tier 3

No it has not:

And the overall capacitance isn't great eithter, as is the choice of the caps.

Because KY isn't low Impedance.

WHy is the Snow Silent in Tier 1 then? 

Or the Dark Power Pro, Bitfenix Whisper, Cooler Master V-Series, Corsair HXi, RMi, RMx, Vengeance. FSP Aurum PT, Seasonic Prime.

Newer Leadex have Sleeve Bearings as well.

None of those use sleeve bearing fans, they're either rifle bearings or FDB and while they are more akin to sleeve than ball, they're better than sleeve bearings.

Yes. And the reason why sleeve bearings are bad is because they don't handle high temperatures well and they don't like being on their sides. FDB significantly reduce those issues.

Still they are oil based Sleeve Bearings and not contact bearings like Ball Bearings or Needle Bearings. 


And why should it matter if they don't handle 'being on their sides'?! Where's that the case? And High Temperatures? Do you live in a Sauna or what?

 

Either Way, gotta watch Milo Yiannopoulos...

They're still significantly improved. 

 

Sleeve bearings have a significantly reduced lifespan when horizontal (like they would be in 95% of cases) and when temps get above 25ºc, which is a perfectly normal temperature for the inside of your case to get to.

Eeeeh from my sleeve and improved sleeved fans, they drop dead only slightly after a sleeve goes. They aren't anywhere near as nice as a double ball bearing based fan.

Ah, I got some bearings confused. Rifles are much better than sleeves regardless.

 

Also none of those have sleeve bearings?

They all are variants of sleeve bearings... Rifle bearing fans aren't that much better than a sleeve bearing.

FDB are a modified/greatly improved sleeve bearing.

Even OklahomaWolf  has his doubts on them, the bitfenix only got away with it due to it's warranty.

Personally, all my rifles died shortly after my sleeve bearing fans went.

Yes because there is more to it than the Name One thing everyone misses on is the most important thing of those fans:


The Lubricant!

 

As we all know there are huge differences in the lubricant, you can use mineral ones, synthetic ones, something inbetween and then there are the additives and so on...


So why should a simpler sleeve bearing fan with good lubricant die sooner than a cheapish FDB/HDB one with also cheapish lubricant?

And, as we all know, it's also important how much of the lubricant gets lost over time and how much the lubricant is designed for logivety...

And of course the sealing of the bearing is also something really important...

 

In the end, everything gets complicated!

 

Oh and don't forget the construction(quality)!!!

 

If they mess up the balancing of the fan a bit, it also dies sooner due to some vibrations...

I've never bought anything by RAIDMAX and don't know anything about them, but they make plenty of PSU's.  They also aren't on here.  Does anybody have any knowledge on the quality?

Make sure to quote or tag me (@JoostinOnline) or I won't see your response!

They're usually shitty, but they do have a select few good units.

Except for the simple fact that a sleeve-bearing wears out by design when positioned horizontally as most systems will require then PSU to be placed in.

But you do.


I have an EVGA GS550 here that BLOW UP! 

Because of Overload -> DC-DC Converter blew. When that happens there is a great chance that you have +12V on minor rails, wich can destroy everything on those rails.
