Antec 75009 92mm Case Fan

Pros: Variable speed control for a good price. Quiet. Good airflow. Multiple power connectors (see below).

Cons: Slightly less thick than Dell stock, which uses plastic tabs instead of screws for the fan, so its a little loose.

Overall Review: Has 3 power connector options. 3-pin for MBs without built in fan speed control. Then an adapter that (optionally) connects to that and splits to a 3-pin and 4-pin. You can use 4-pin to PS, then (optionally) use the 3-pin to make your MB's built in fan control happy, to avoid POST errors about "no fan connected" on systems like Dell.

Comments: I installed one of these in a new P4 3.0c system two weeks ago. After lots of research, I came to the conclusion that unless you need significant airflow (i.e. 40+ CFM), this fan actually has the lowest acoustics while still moving adequate air. So far, that seems to be holding true as my temps idle at 32c with the fan still spinning 300RPM under max. And I can't distinguish the noise from the power supply and the stock Intel heatsink/fan. It's definitely worth the money.

Pros: It fits physically and electrically. It is quiet, and causes very little noise, but does cool adequately.

Cons: None.

Overall Review: Antec products are high quality items. My only contact for service with Antec was earlier on another product, and I received a prompt and correct answer, which included the information that I requested. Other manufacturer's sometimes only give a "canned" reply, which has nothing to do with the original inquiry.

Pros: Says what it is and does what it says.

Cons: Wasn't free and doesn't come with a Dell MoBo connector.

Overall Review: There's a lot of confusion among the reviews here. If you have a three-speed fan, it's possibly a TriCool, but it's *NOT* a SmartCool. The SmartCool is a variable speed fan. The humming/whining others have reported is because it uses PWM to control the speed. If your fan has an LED, I dn't know what it is, but it's *NOT* a SmartCool. The fan fits my aging Dell 8100 perfectly. But I did have to splice the old MoBo connector onto this new fan. No problemo.

Pros: Thermally activated speed change. Supposed to be quality.

Cons: Supposed to be quality. I bought 2 for front intake of Antec P150 case (great case). After about month, I'm getting a noticble high pitched whine that my ears can pick up from over 15 ft away. I disconnected them and confirmed them as the source. It's irritating to have a quiet system and hear high pitched fan spin noise. I'm going to buy 2 others from another company.

Overall Review: I'm not that picky about whooshing sounds, but I am picky about high pitched sounds reaching my ears.

Pros: Works well, Lowered my CPU and Motherboard temps. Does as expected. I have two of these installed on the front of my case and even with two it is very quiet.

Cons: When I first installed these they made a very very loud clicking noise. After some inspection I realized that the fan blades were hitting what appeared to be the temperature sensor on the center of the fan. So I just bent them back a bit and it worked perfect.

Pros: works with Dell Dimension 8200. Does not connect to cpu fan header on motherboard though as the dell connector is proprietary. All you have to do is go into the BIOS and disable keyboard error reporting. Connected to spare connector on power supply.

Cons: no cons really

Overall Review: beats having to spend three to five times as much on a hard to find original Dell fan

Pros: it works thats about it

Cons: the 3 pin motherboard connecter would not work on mine so i had to use the one that goes with the powersupply so far its ok
