It seems there's a lot of CPU coolers with different types of bearings. Some have what's called "Long-life Sleeve", others are "Ball Bearings", and there's a mix of fluid, magnetic, hydraulic, etc; I think Newegg lists 15-20 bearing types. And Wikipedia narrows the list to just 5 main types. My question is what is the difference between each bearing type, and are the differences minor or major adjustments? From what I read, sleeve aren't so great, rifle are more for budget-conscious, and ball, along with fluid are top notch? And is fluid bearing somewhat "similar" to liquid cooling in that some form of liquid is used? And is there a risk for this "liquid" to leak?
And I watched your "air CPU cooler" video. Is Xigmatek HDT S1283 the only cooler that offers Limited Lifetime Warranty? (according to Newegg). The 2nd largest warranty I found was 6 years for Arctic Cooling Freezer 7. But it seems most offer 30 days to 1 year tops?
Since that video was created 2 years ago, what would you say now is the "best" air cooler on the market right now?
the liquid bearings just use liquid to lower the resistance between the turning parts and the static parts. the fluid bearing is best when you don't stop and start to much because it needs to make a small layer between the moving and static parts. the ball bearings are also very good and use small balls to lower the resistance. hydrolic is the same as the fluid. magnetic uses magnets so the moving parts don't touch the static parts but there will be some resistance because of the magnetic fields but no damage when moving. the sleeve bearing are 2 meals that rub along each other and when they use the right materials than it will last long but it has higher resistant. i would say go for fluid or magnetic, ball bearings are also good at lower speeds.
the liquid can leak but it is oil and if it leaks than the bearing is bad or destroyed and there is only very little fluid in it. so no danger for destroying your pc whit it.
so ball bearing low to high-medium speeds many start stops
fluid medium to very high speed not so good for starting and stopping
magnetic low to very high speed dunno abouth starting and stopping. (i didn't learn it at school)
PS. i mean whit resistance friction
