There is nothing the matter with sleeve bearings. Most internal combustion engines use similar bearings.

I have some TY-140 fans that have been in use for a long long time pretty much running 24/7 .. I think about 6 years now. They are still as quiet as they were to start with.

Fan Vibration Dampening With Grommets like used for Electrical Work
One of the best ways I've seen and used is with old fashion wiring grommets.


The case usually needs the hole drilled out so grommet will fit. Drill hole big enough so grommet is a nice loose fit. This way when screw snugs up it does not force the rubber hard against the edges of hole.

Also solves the problem of blind mounting of screw through a rubber wash without it touching the case. A vibration mount only works if it separates the vibrating object (fan) from what it's mounted on. If any part of fan or it's mounting hardware touches what it is being mounted to, the vibration is transmitted through this contact.

Additionally, the screw must not be tightened into fan too tight or the 'vibration mount' is compressed, becomes more dense and transmits the vibration. wink.gif

Doyll since I'm attaching one PWM fan (one of your recommended Noctuas, the NF-A14 Industrial PPC-3000 PWM)
to my Zotac GTX780 PWM connector using a mini 4-pin PWM adapter I don't want to cut any of the wires on the
adapter right?

If that is the only fan on GPU than leave it connected. thumb.gif

And for what it's worth, I use Thermalright TY-143 fans, not NF-A14IPPC-3000 PWM fans. Plenty of oomph and much lower priced. wink.gif


Fan Bearing Types; Ball-Bearing Versus Sleeve Bearing and It's Fluid Dynamic Variants

For all intent and purpose, we have 2 kinds of bearing fans. Ball and Sleeve. It doesn't matter what fancy names fan companies put name there sleeve bearings, they are still in the sleeve bearing family. Fluid bearings are basically just sophisticated sleeve bearings with slightly different ways of using the lubricant in the space between the bearing sleeve and shaft. The lubricant between the shaft and sleeve is what they are referring to when the call these bearings 'Fluid Dynamic Bearing". But almost all sleeve bearings require lubricant too. After all, lubrication is what keeps bearings from getting noisy and seizing .. even ball bearings. tongue.gif

Bottom line is the quality of bearing is far more important than what kind of bearing it is, be it ball or sleeve. Poor quality ball bearings will fail before good quality sleeve bearings. Yes, a good ball bearing has a longer life expectancy, but we are talking 80,000 to 95,000 hours @ 25c, or 52,000 to 75,000 hours @ 40c. That is almost 6 years of use without ever being turned off. How many of us will be using the fans we buy now for that many years?

The crankshaft bearings in a V8 have oil being forced into their
bearing surfaces under high pressure, a fan sleeve bearing
doesn't.

Many internal combustion engines don't use rod bearings, single
cylinder engines and V-twins commonly use needle bearings.

I've also read sleeve bearing fans don't work well in horizontal
mountings.

Most internal combustion engines I've worked on (thousands of them) have rod bearing, crank shaft bearings, etc., and few of them are using needle bearings / roller bearings.

But please feel free to believe what you want.

And for the record 2 of my original TY-140 fans are bottom case fans. Oh!, and the TY-143 has ball bearings. wink.gif

Ever worked on 2-strokes? Ever worked on any singles?

Thousands of engines? WHERE?

Just one engine every two weeks is over a thousand. biggrin.gif But my background in internal combustion engines is off subject. We digressed in your attempt to paint all sleeve bearings as the devil's seed.. and they are not .. in fact some are quite good. After all, most fans do have some form of sleeve bearing. Some are excellent .. some are quite bad. You paint them all bad with a single brush stroke, I don't. This ends here and now.

Fractal Design Define R2 (& other Define cases) modified to 140mm fans, bottom & back grills removed, front refitted to 140mm fans

I have left the Titan and pci bracket area alone. Still thinking about upgrading to a 980ti or 390x in the near future. If I decide not to, I will work on the bracket of the Titan. Considering it was the first time I took on a project like this, I am happy with the result. Before & After Images (Click to show)

It is not the temperature, but the noise that was bothering me. Never had good results lowering the the temp/noise by using a sidepanel fan. It messes up the airflow in the case as well.

I had recently purchased an Air 540 in Arctic White to do my black/white (mostly white) themed build. I am running an Asus Mark S Sabertooth with the Avexir Sabranco limited edition ram sticks and a Galax GTX 980 Hall of Fame gpu. I know some of that seems irrelevant, but I kind of wanted to give an idea on the theme I have going on here before I ask my questions. I was wondering which black/white fans would be optimal for my case? I am trying to further understand your guides to help choose and set up my fans. Also, I would like a matching cpu cooler that will still allow me to show off my blinking white LED lights on the ram without sacrificing cooling performance? I hear that the mounts for the front intake on the air 540 can slightly restrict the airflow when using two 140mm fans instead of 3 120mm fans. As far as cpu cooler goes, I know there is a Dark Knight II Frostbourne Edition that seems like it may fit well with my theme - http://www.techpowerup.com/180801/xigmatek-dark-knight-frostbourne-edition-cpu-cooler-announced.html. Any suggestions on case fan choice/setup would be greatly appreciated. What is your opinion on the Aerocool Dead Silence case fans? I am also considering the TY-147A fans. I live in the United States, but I don't mind having anything shipped from overseas. Thanks in advance!

Sorry for the delay. Busy weekend chasing bunnies. biggrin.gif

Some of this you already know, but here goes.

Your Mark S Sabertooth has about 50-52mm center CPU toward RAM.
Avexir Sabranco is 30mm tall

Cryorig R1 Universal is mostly white and is 48.5mm center CPU to front of 13mm front fan.



Stock fan clears no problem. Using TY-147 or TY-147A fans or some other white fans would move fan over RAM a little.





Not many white coolers out there. I'm not impressed with the Dark Night coolers. Have you considered using white light gray spray paint on a cooler? As long as the top is color matched to your system, the fins hardly show. And by spraying at a steep angle the edges get colored when painting the top of cooler without hindering cooling. We just don't want a lot of paint going between the fins, but on the edges it no problem.

I have never used Aerocool fans so can't really help there. I do use TY-140, TY-143, TY-147 and TY-147A fans and love them all.
