Question: How do I reduce or eliminate the fan noise?
Document: Good quality enclosure.Quiet - no fan noise.Easy to assemble.Good performance.Not sure what else I wanted. I would buy this again.
This product is extremely noisy. The fan makes A LOT of noise when operating.Handles well big hard drivers (mine is 3TB), and the case looks good, but the noise.... horrible.I do not recommend this product.
I am happy with the performance of this enclosure, but the biggest downside is the noise of the fan. Yes, the enclosure has a switch to turn the fan off, but I found my HD getting too hot and operating extremely slowly until I turned it back on. I returned the first unit I received because I thought the fan had a defective bearing, but the replacement unit is exactly the same.
We like to keep our office quiet. Other reviewers said the fan was quiet, but I was concerned it might be a bit loud in our low noise environment. No worries! The fan makes very little noise, almost none at all. My second concern was ease and speed of installation. An Inland branded enclosure was on sale for quite a bit less at our local computer store. But it requires 10 screws instead of the StarTech's two.
I had an almost new to but too noisy for my desktop WD black 2 TB hard drive which I swapped for another brand so had extra. I put it into this enclosure because it had a fan, power switch, and was SATA 3.0. I only run my offline drives when I actually am backing up or using those files so most of the time the noise that the WD hard drive makes doesn't make a difference as it's turned off. Perfect solution.
Very well built. Supports drive spin down after delay. I like how the fan has a switch, this is nice for reducing noise for drives that are not constantly being used. However the fan is nice and quiet to begin with so its not a problem to leave on all the time.Only thing that bothers me is unnecessarily bright LED. It lights up a bright blue strip up the center of the enclosure. I made sure to unplug it before closing up everything to keep my studio apartment dark at night.
I have bought other enclosures of late which also contain fans. They do not work as well - this one keeps the drive cool even when it is used a lot and facilitates the drive working well. For reasons I find difficult to understand, other brands of enclosures promote actual drive noise in such a way that the drives run quite hot.Since I'm a software engineer, I consulted with hardware colleagues to see how this could be possible.
This item is very nice. I love the build in fan. keeping the HD cool. Runs quiet and well build.
The enclosure is very similar in shape and size to a Western Digital My Book, but this one has a fan. I just hope it holds up. Only time will tell.
When my computer crashed I wanted to make sure the hard drive was okay. I love that this has a fan in it, so it won't get overheated. Very pleased with purchase!
Answer: There is a switch near the power cord inlet to turn the fan off
