I dont understand how people can pop the fan part off of the metal and electrical parts like nothing. I broke 2 blower fans at the part that joins the triangle plastic thing to the PCB (actually, just before it, it leaves a circle piece of plastic left in the PCB part)

I think the key is to raise all the parts of the fan at the same time, since you do not have access to all the parts of the fan at the same time, some parts will be lifted first, but only marginally, if you lift one part too high, then the spool will get high tension from that side and becomes more difficult to lose

I guess another solution is to use 5-7 strong string to evenly tie the fan blades at different parts and drag the fan out slowly

Same here.

I once tried to take this fan apart and I could not pull it off with all my force.

Maybe the 3 screwdriver trick can do it ( but I have not tried that myself ) Huh

Another type of fan from 5870, this one is much easier to remove, and there is a black heat pipe on the back of the VRM cooler part, so that it can run easily at 900+ mhz

Care to provide some more details with how you applied pressure. I tried it on a fan which was already "noisy"/failing and just ended up breaking it.

Running 5970 24/7/365 isn't "normal" wear and tear so ever fan will eventually need to be re-oiled and/or replaced.

Which part did you break?

At first I took the fan down, using the method from the video: 3 screw drivers from each corner. But that did not work, the red triangle plastic base on the fan bended a lot, almost reached a point of danger, so I remounted fan firmly on the cooler, and raise out side of the wheel (close to the end of the cooler) using a 5mm diameter screw driver shaft, and push the inside of the wheel from the back of the cooler through that long opening, slowly increase pressure, not very easy, but it will eventually pop out. I guess if you push too hard too quick, the spool will get destroyed, so it is best to push through all of those holes on the cooler at the same time, maybe 5 small fingers or something like that will work

My first lubricant was very fine graphite. I then tried the sewing machine oil. So far the graphite has worked great for helping fans in the past, but someone recommended the sewing machine oil and I figured why not.

I just took mine out to try the fix. Adding the lubricant helped for about 15 minutes of running. So I just ordered a replacement from ebay.

Yeah. I think if the bearing is shot / damaged then there is no point adding lube.

What lube did you use ?

Thanks !

I don't know what he used but sewing machine oil is a good choice for oiling fans. Never use WD40. It isn't an oil for some reason people think it is though.

Is there any thing better than sewing oil ?

Is this FanLube stuff just marketing ( expensive too ) or really worth it and better than regular sewing oil : http://www.noisy-computer-fans.co.uk/

See here the last points comparing this and sewing and 3 in one oils : http://www.sunbirdmanagement.co.uk/FANLUBE/FanLubeFAQs.htm

As always, I appreciate your detailed and researched insight D&T !

Ahahaha! That is great. I just did that, playing with a ~~jet engine~~ Delta fan from a server PSU.

damn you.

i just tried it on mine, and the spool part snapped off. Angry

Sorry to hear that, maybe there is a safer method. There are lots of openings on the cooler under the fan, I guess it should be easier to push the fan through all those openings at the same time using same pressure, thus the spool will not get hurt

luckily, it's the one i already replaced.

i also found out the fan has shitloads of cat hairs in it.

After seeing the video, I decided to do it myself. It seems the most easy way to pop up the fan is to keep the fan screwed on the cooler, raise the outer side of fan wheel with screw drivers and push the other side of the fan wheel from the back of the cooler (through the long opening on the cooler base), you can apply enough power with this method without worrying about damage the fan, it will pop out with a "click" sound (first make sure it is a brush-less fan)

As seen from the fan wheel part, the root of the axis are thinner than the axis, under normal operation this part is locked by the black plastic bearing well on the hub, apply force will push the axis out through that plastic bearing well. The metal axis bearing in the hub is totally sealed, oil can be contained inside for a long time, the only possible leakage is from the black plastic bearing well, which will certainly get lose every time you pop out the fan wheel. So I added some mineral oil inside the metal axis bearing house and put some bearing grease on the root of the axis, hoping that the grease will seal the black plastic bearing well

In principle, such a construction will almost never need re-oil, unless the fan is always running at high speed in hot weather, thus the oil vaporized
