Pros: - Fits most towers.
- Comes with attachment for power supply, so you'll be set most ways you look at it.
- Fairly decent length cable, so good for wrapping around locations if needed.
- Relatively quiet.

Cons: - It is like most other fans you will get. Nothing necessarily impressive about it, except for the price-point.

Pros: These don't provide a ton of airflow, but are very quiet. I use one as an inlet cooling my hard drives and another inlet blowing over my graphics card in each build I do. Using motherboard fan control you can dial them in to the desired noise level and they provide enough airflow to noticeably reduce temperatures (even though I only run 2 as intakes, exhaust fan is always a larger fan). The ones that are in my own computer were purchased back in 2004. That's right, 12 years of almost 24/7 operation and still going. In my experience so far with these fans the bearings are good to 4-5 years of always-on operation and then they start to make a roaring noise. When they start making noise it's time to pull them out, remove the sticker on the stationary part, pry off the little plastic cap, clean out the inside (X-Acto knife and a can of keyboard cleaner does the trick), and then put in some kind of lubricant. I have used 6 of these fans over the years and every one of them has needed this fix after a while. I have used regular oil like you'd put in your car, 3-in-1 oil, gun lubricating oil, and even tried white lithium in one fan. The one with the white lithium grease in it does spin slower than the rest now but that was just an experiment to see if anything worked better or worse than the others. All of the oils seem to operate with similar efficiency (measuring fan speed via Speedfan's readings off of the motherboard) but I have yet to have a single fan fail.

Cons: Not terribly high output
There are other fans on the market that offer more CFM per dB.

Other Thoughts: These fans are cheap, quiet, and with a little bit of work seem to never go bad. If you're running a high end system that requires a lot of airflow I'd look elsewhere but otherwise I highly recommend them.

Pros: Blades spin without much noise

Cons: Nuthin'

Pros: Bought some of these to max out my case ventilation. I don't care so much how much noise it makes; goal is to get the heat out. Ran out of board connections, so have one (HDD) fan running at full speed. The others seem to be working well with the bios mapping (voltage mode.)

Cons: None. Will revisit if they decide to start squealing within a couple months.

Pros: - Very quiet
- Pushes lots of air
- Inexpensive
- Very good quality
- Screws included
- Molex adapter included

Cons: - None so far

Other Thoughts: - I highly recommend this fan. Excellent quality for price. Replaced a stock fan.

Pros: Bought two of these, they run basically silent. Would definitely recommend these fans to anyone. Decent cable length and can tuck them around the sides if need to bring up the slack for cable

Cons: None

Pros: Pushes plenty of air and are fairly quiet.

Cons: They could be somewhat quieter but not bad for the price.

Pros: Quiet. Cool. Cheap.

Cons: I ordered 2 of these fans. One of them came DoA. Not worth it to RMA. The shipping label will cost more than the fan.

Pros: Solid construction, standard 80mm case fan that runs VERY quiet and smooth. I replaced fans in an older PC case with these and it runs so very quiet and stays cool. (nothing outrageous inside that case).

Cons: None.

Other Thoughts: * If you can fit a larger fan, get a larger model of this fan, you will not be disappointed.

Pros: Nice looking Moved air well and were nice to add to any case for special cooling like putting at a side screened area of computer to move air out of case

Cons: Never had issues with Cooler Master fans
