Hi all,
White ceiling fans come standard as part of my build, but for $10 extra per fan, I can get the stainless steel coloured fans which look a little smarter.
Are these worth the extra money, or just a bit of a waste?
Many thanks,
Dale

I would have imagined that a thinner steel blade would make less noise as it would 'slide through the air' with less restriction ? I'm looking at buying my ceiling fans now for my build, so I'm rather interested in this thread. Owner Building at Jimboomba Woods in Logan City Qld.

Re: Choosing Ceiling Fans 6Dec 19, 2014 9:43 pm I have gone stainless only in alfresco and living/dining, so if there were more noise it wouldnt be a major issue. Still interesting if they did produce more noise. Standard white fans in the bedrooms. I only went stainless purely for the more refined/modern look Dale - Building Newbie Proserpine, QLD Re: Choosing Ceiling Fans 7Dec 22, 2014 5:51 pm We have also been advised that steel blades are noisier especially in bedrooms. We have purchased a couple of white ones with wooden blades for our current rental we're living in - for noie and also to match era of house... For the Alfresco we're going marine grade steel. Re: Choosing Ceiling Fans 8Dec 23, 2014 7:51 am We have both steel and wood blades and there is no discernible difference. Unless the fan has excessive mechanical vibrations or electrically induced harmonics within the motor, the majority of noise will be simply from the blades striking the air. Steel blades may carry electrical resonance (hum) a little better than wood, however it's unlikely either material will have a noticeable impact on the loudness as most of it will be emanating from the body of the unit. The blade design and profile is far more likely to be a consideration in fact. Re: Choosing Ceiling Fans 9Dec 23, 2014 11:06 pm Is it possible the louder noise from the steel fan before was because it was a lower quality fan that was simply noisier because of quality of it, rather than simply steel blades ? I just don't understand why blade material would make it louder. Owner Building at Jimboomba Woods in Logan City Qld.

Re: Choosing Ceiling Fans 10Dec 27, 2014 7:53 am CC101 dolphinblu I have been looking at ceiling fans at the moment. I have been advised that fans with a steel blade are noisy. Particularly if you are looking at installing them in a bedroom. yes - I agree. + 1 steel blade are noisier. We experienced this with our reputable branded fans. Not what's it's offensive but we could hear it Re: Choosing Ceiling Fans 11Dec 27, 2014 9:07 am Crazyk + 1 steel blade are noisier. We experienced this with our reputable branded fans. Not what's it's offensive but we could hear it That's what we're asking about, was it brand or blade type. In your case it was steel blade type. What brand was it that had the noisier steel blades ?

Ceiling fans are the product I use as the classic example of a product (mostly) designed for point of sale visual appeal rather than technical excellence to best perform their intended function. Air noise is mostly a product of blade tip speed and more noise results from larger swept areas. An efficient fan blade will also have less spillage and reduced wing tip vorticity induced drag. Wide and thick flat blades are inefficient due to their greater surface air flow separation (pressure drag) whereas multiple narrow blades add to the swept solidity ratio without increasing drag. Four blades are better than three and so on. Blades with a well designed 'twist' increase the effective aspect ratio without materially increasing the span plus it keeps the blade's angle of attack relatively constant along its length as well as reducing hub spillage. Is is always better to have a fan that operates with greater aerodynamic and energy efficiency at lower revolutions than one that relies on greater speed (that generates more noise) to combat poor efficiency. Having negative rather than positive or neutral rake for greater throw is also better. The next time you are in Bunnings, look up and look at their BIGASS Fans (trade name). You will see their multiple narrow slow moving blades with winglets that reduce spillage and parasitic drag caused by wing tip vorticity. You will also notice that the fans are above open areas for greater swept boundary layer efficiency. The only mistake BIGASS Fans seem to have made is their unfortunate choice of ISIS as the trademark for one of their smaller fans. 3in1 Supadiverta.

Re: Choosing Ceiling Fans 14Feb 08, 2015 3:44 pm The BigAssFans are brilliant. They do a slightly smaller-assed fan called the Haiku, which in my humble opinion is a masterpiece of design and engineering. Basically, to choose a good ceiling fan you want something that moves big volumes of air at a low velocity. To do this you need bigger blades, more of them, at a lower pitch angle. Your cheap run of the mill 1200mm 3 blade fan with ribbed steel/aluminium blades is going to be noisier and less effective than a 1400mm 4 or 5 blade fan with smooth timber or polymer blades. I highly rate the Hunter Pacific Concept fans, they are very good quality, they look slick, are whisper quiet and move air very effectively. I used to be an electrician so I have installed a lot of ceiling fans in my early career! For what it's worth, I really don't like the look of stainless steel fans, downlights etc. Very 2005!! That is just my subjective opinion of course - choose whatever you like the look of!
