I am on my second fan in 2 weeks, the first one did not turn on at all, the second is not balanced and vibrates and will vibrate across the floor , is it worth trying for a third fan? Do your fans vibrate?

My fan works perfect for almost a year and a half in a Florida garage. Hot as blazes and on low speed. High speed would suck the doors in. No sign of rust either.

Cody.. Which fan did you end up purchasing. Doing the same thing. Current fan I am using is not powerful enough.

The internal fan is broken, same with mine. Opened it up and its a cheap computer fan. I replaced it for 4 dollars at a computer store and it works. If you're under warranty, send it back or take the risk and replace the fan.Good luck

I would honestly contact Noctua support. IIRC this cooler comes with extra clips for a second fan. If you damaged a clip or were shorted one, I'm sure these guys will replace it. The cooler comes with a 6-year warranty and I've read countless occasions about their customer service being second to none. So I'd say start there! http://www.noctua.at/main.php?show=support&lng;=en

@ SummerOneThanks for your input on this. Seems like the newer manufactured units are less prone to buzzing than the older ones. Also, seems like the buzzing on your first one was caused by the damage if it was a really loud buzz that you were hearing.I'm getting my panel replaced in January and will let y'all know if mine stops buzzing or not.

Hi, yes this is normal. It only polls one fan, the other fan is slaved to that fan. It cannot make them both spin at independent speeds.

Yes, exact same problem on two fans. Had first one die first week, then a second one after a couple months. If you reverse the direction, the fans turn off for a few seconds, then reverse. If you adjust the speed without waiting for the fans to kick back on, something goes haywire, and it fries the fuse immediately. If you replace the fuse, the fan continues to run, won't turn off or respond to controls, and the fuse blows again. Their warranty service cannot replace the fan, because "They don't have stock"... "Call back in 4 months". If you have one of these fans, give the fan time between changing direction and changing speed. Both fans died in exactly the same way. The fan is great until it fries.

I bought this fan (used) from low_baller and after a week it started to rattle a bit. I sent them an email describing the issue and in less than a week they sent me a new unit and a return shipping label. About to buy the combo pack as I need a 2nd fan and in bad need of a filter.

I've had the same experience. Can't get it apart again. I'm just going to buy another fan.

Either they have changed the specifications, or your unit is defective. The fan on my unit only comes on when I've had it under heavy load for awhile, then shuts off awhile after the load is reduced.

Return the fan.... only one blade works on mine on cool but I use it mostly for exhaust so I'm not gonna go and return it since both blades work fine on exhaust

The cooler part of my two fans are about the only thing that has kept on working. I have returned by fans to the manufacturer at least four times for repairs which is about the only thing you can do if you are having a problem. Wish I had a better answer for you. If you are under warranty, they will do the repairs for free but it is pretty inconvenient having to box up and return the fan. Give them a call and they will send you a UPS label so you can ship it back at no charge. Hope this helps.

Hi Nancy, I am on my third fan. They seem to last me about seven or eight years. After that they get noisy or stop altogether.

If the fan is not working, the fan is dead. The fans are really cheap to replace. Contact David Chan at AZZA COMPTER (714) 990-5625 for a replacement fan. The fan should be about $ 15.00. You will have to send him a personal check. He will tell you where to send it. Make sure you tell him you need him to send you the 230mm fan.

Sorry for your problem but I can't be sure my experience will help you. Mine was direct-wired and burned out in a thunderstorm. Replaced it with a different version. Fan still works fine.
