Pros: I like the concept of a temperature controlled case fan.
Cons: I bought two for the price of one. Even at low speed, they are as loud as the 23 year old Elina fans they replace, while putting out much less air. The sound of the Vantecs I received has more of a "rattling" quality to it than the Elinas, which have more of a "roaring" sound. The rattling sound makes Vantecs sound older than the Elinas are.
Summary: Bought two of these to replace the stock fans in a Thermaltake Lanbox lite. They are whisper quiet, and move enough air to serve their purpose easily. I've never bought a Vantec product before, but the packaging and the product are both top notch.
Summary: I'll probably go find some pins or something and make the power leads run off the 3-pin connector instead of the Molex, but I'm satisfied for now.
Pros: Simple, cheap design that gets the job done. Quiet, too.
Cons: Vantec should have used all three pins on the 3-pin motherboard connector. Instead they only use the third pin so you can read the RPM's from the motherboard, but use Molex connectors for power. It's not a huge problem but it's an annoyance.
Summary: Added a pair of these to the back of an old case with new motherboard, processor, graphics card and RAM that generate substantially more heat than the case was designed for (ATX desktop box that dates back to Win95 Socket 7 ATX motherboards). Knew it would need better airflow before rebuilding it. Gave a great, heavy-duty steel case a new lease on life!
Pros: These are great fans to use for additional heat exhaust. Only spin up as much as needed based on air temperature flowing through them reducing noise factor when full airflow isn't needed. Just remember that the temperature sensor is in the fan body . . . and therefore it should be used as an exhaust fan pushing hot air out of a case. Given their 60mm size, they're still quieter, even at full speed, than other fans in the same size and bearing class. If you need quiete...
Cons: My only wish is that they could be powered by the motherboard instead of only the fan spinning sensor wire connecting to the motherboard. I will ultimately remove the bulky four-pin drive power connector and put the power connection in the same motherboard connector as the third sensor wire. Would have gotten five eggs if not for that.
Summary: I got this for my Tivo.... and it never really cools off enough to become very quiet. I had a Silenx fan in there before, which was much quieter than this model. It didn't move as many CFMs, but it worked well enough AND was quiet. It would do much better in a setup where the fan could be mounted away from the power supply, because then it could cool down enough to slow to quiet speeds. Unfortunately, that isn't an option in my setup.
Summary: For all those silly people saying this fan needs longer screws to use with their CPU, don't be ridiculous. This is a CASE fan, *not* a CPU fan. It doesn't produce nearly enough airflow to keep a CPU cool. But if you insist on melting down your processor, don't say you hadn't been warned.
Pros: Runs very quietly. Automatic temp sensor to adjust its own speed. Has wire for mobo to detect RPM. Even includes screws.
Cons: Not a whole lot of airflow, but this is a pretty small case fan.
Summary: I was concerned because some people wrote reviews that said this fan was noisey. So many others said it was quiet that I gave it a try. I bought two to replace ones that came with my case which have since gone bad. These blow just as much air, although I admit that's not a whole lot because they're so small. I give them a thumbs-up.
Pros: Nice and quiet. Reasonably priced.
Cons: Not a whole lot of airflow, but what more can one expect from such a small fan?
Summary: This little fan has the exact size for most AMD stock coolers. It also has a small thermistor that detects the air's temperature and will throttle the fan's speed to deliver adequate airflow. Ideally, this is for users searching for efficient cooling. It pushes a very good amount of air and is not too loud. Overall, a nice Vantec fan.
