This fan blew me away. I was making a cooling system for my laptop and wanted to run a 4 inch hose trgough the desk to the underside of my laptop. I purchased a random4 inch fan that was not very good so I decided to go larger. I happened to see this fan on sale and thought it may be too good to be true. Well it is not, i was going to go 6 inches but the 8 inch was less than other 6 inch fans so I bought one. The first time I turned this fan on I actually thought my laptop would lift off the desk. I coul only laugh at the amout of overkill for my needs I got. But hey overkill can be good. The little control unit that comes with it is a little chunky when trying to navigate but i like the fact its lit up and you can read it in a dark room. Tge speeds range from 1 to 10 and each one is a clear and progressively higher step in fan speed. I put a 6 inch reducer on my since I had 6 inch ducts alreadynand it was only going two feet from being mounted on my the underside of my desk through the desk to a cistom duct holder and stand for my laptop. I use a custom filter to try and minimize the dust being pumped into the laptop vents. It works really well and i never have to turn it up past 4 and it moves a lot of air. This fan is worth every pennyand it moves so much air that I buy a second one for my den to circulate the ac cool air since i only have one vent in a very large room..Short answer is this fan is powerful and moves a ton of air!!! You will not regret your purchase and sometimes it half the price of other less powerful fans. I paid 25 percent more than what i paid for my 4 inch fan that wont even blow a piece of paper.The fan can get louder at around the 7-10 range but i was surprised at the quietness in relation to the amout of air being passed through. Over good fan!

I just got this fan a few days ago to replace a noisy relatively power hungry inline fan i already had. My first impressions are pretty good. I haven't installed the fan how I want yet, but I have messed around with it. First off, the description says it's 68 watts, I hooked it up to my kil-a-watt, and at maximum speed, it only draws 59-60 watts. So that is deffinately a bonus. While down at speed 2, it draws about 11 watts and still moves a decent amount of air. I do not have an anemometer or anything to verify flow rates. As far as noise, I haven't checked it with a decibel meter, but it's not the loudest fan in the world. Speed 2 you almost can't hear it, at 3 you start being able to because the Humm it creates is sort of a higher pitched Humm, not a deep lower tone. At speed 10, it gets kind of loud but not the loudest fan I've had. This review could possibly be premature, but overall I'm satisfied so far.

I have only been using this fan (8 inch w/ controller) for a few days so this is an initial impression. For those interested, read on later for tests that I conducted. The fan comes with a controller and a temperature and relative humidity sensor. The fan alone WILL run without any of these hooked up, but it will be at full speed. The amazing part is the controller that will allow the fan to be run at ten different speed settings. It appears to draw a lot less current than the fan I replaced, although that was 10 years old or so, and it runs quieter even though it moves the air 12% faster than the old one. It also can be run with only the controller attached but not the T/RH sensor, so unless you need to have it turned on/off at specific T or RH settings, it does not need to be hooked up. I can't imagine buying the model without the controller, which is nearly the same price.Following is the technical information. Speed setting 10 - full: 67 watts, 2800 ft/min (all readings are at no load/resistance right at the fan outlet. Ducting friction will reduce the air flow. For my situation with 3-90 degree elbows and 50 feet of flexible spiral ducting, the outlet is 1600 f/m at the 10 setting); 9: 57 w, 2500 f/m (89% of full speed); 8: 47 w, 2300 f/m, 82%; 7: 41 w, 2200 f/m, 79%; 6: 35 w, 2000 f/m, 71%; 5: 29 w, 1900 f/m, 68%; 4: 24 w, 1800 f/m, 64%; 3: 19 w, 1600 f/m, 57%; 2: 12 w, 1350 f/m, 48%; 1: 6 w, 1000 f/m, 36%.For comparison, another fan I have with a variable speed L to H controller, the lowest speed is 73% of the maximum. If you want a wider range of speeds available, particularly at the slower end, this fan is a fantastic option at an unbelievably low price. I have already ordered several others. Even if it fails in a year or two of nearly continuous use, it is still a great value.
