StarTech.com Expansion Slot Rear Exhaust Cooling Fan with LP4 Connector (FANCASE), Black, 1 Count (Pack of 1)

Threw it on top of my GPU and it dropped my temps by 4C under load. Way more than I expected for how inexpensive it is. Moves more air than either of my other exhaust fans.Super easy to install. You'll need a molex to 3pin adapter if you want to hook it up to a fan controller.You can also easily take off the little metal mounting piece and put it back on upside down if you'd rather have the fan intake from the bottom.As to how loud it is, it isn't nearly as bad as other reviews led me to believe. It's definitely audible, but nowhere near the jet engine I was anticipating.It's a little thicker than I thought it would be, but I was still able to mount it in the PCI slot directly above my GPU. It would probably be even better if I could move the fan up a slot and have an empty PCI slot between it and the GPU, but my configuration doesn't allow for it.Would definitely recommend for any niche air cooling application.

It’s a little on the noisy side but I’m not the kind to complain about it, nowhere near as bad as some Dell fans I’ve had from the factory. I’ve got it in my Dell Dimension 8300 in an effort to help keep the FX5200 cool, and soon it’ll help keep the Radeon HD2600 PRO I’m getting cool. Works well and I have no complaints.

I love that it supplements the cooling of my Graphics Card. It moves a good amount of air, yet it's very quiet. I don't like that it doesn't seem snug in it's slot. The one screw holds it in there but it has some play going side to side. Not alot. My current build doesn't have the luxury of too much space. I keep my machine laying on it's side so it negates any possible collisions inside. Good quality affordable supplement to your machines cooling setup. I'll get a bigger case and purchase a couple more of these.

Previously I've used 40mm fans mounted by forcing screws in to the heatsink fins, but I recently upgraded to a 16 drive controller that has a giant heatsink with smaller fins. These controllers are designed for high volume server fans. I tried using a dual 90mm pcie fan mount bracket, but it was just pushing hot air around the case and not really doing much good. It was better than nothing but I went on the hunt for something better.Then I came across this fan. Like everyone else, I wish they would update the design and get rid of the molex connector but I dug out the cable for the PSU and hooked it up. For the people claiming its loud, sure it's louder than a noctua fan running at 1000rpm, but it's not THAT loud. I have a spare bedroom where I keep all my pc's and I don't notice this fan over the other fan noise in the room. With the door open I can barely hear the pc's running, and this fan doesn't stick out above the rest.It does move way more air than I expected it to. When I put my hand behind the case I can feel the warm air it's sucking out from the sata controller I have it mounted next to. It has lowered the temps of the controller. It's not substitute for having a 3000+rpm fan blowing air over it, but it's enough for me to be comfortable with it. If you need something to keep the temps in check for a card like this I would recommend it, if you don't have access to a 3d printer so you can make a proper fan shroud. The fan takes up exactly one pcie slot, so you aren't giving up more space than that.

I bought two of these fans to cool my Samsung 980 PRO SSD temps (55C) in my Asus ROG Strix Helios case. It looks very pretty but airflow is very poor, causing higher temps on my SSDs. I already had a (3)120mm fans as intake and a 360mm Corsair H150i AIO and 1 other rear fan as exhaust. First attempt to resolve the temperature problem involved moving my EVGA RTX3090 GPU from Horizontal to Vertical mount. This helped reduce temps by ~ 3-5C as it allowed for better internal airflow.Then I added these fans and for faster air movement and now my SSD temps are 35C- 40C which made me happy. Slight caveat ...1 fan is ok as it drops temps just as much, depending on placement of device you want to cool. Noise is almost inaudible from my location.I added a second one to cool the boot SSD next to my CPU (i9-13900K) and now both my SSDs are very cool (literary!)...but the added noise of the second fan is the price you pay.Give the fan about 10 minutes to do its work. You wrong be disappointed.

I had an old legacy graphics card running on my dual-boot Win 10 Pro 64 bit & Win XP Pro 32 bit. The card, and motherboard, started creeping into the high 70s, even with mild internet browsing or video watching - NO games or intensive power-hungry programs. While watching videos, or with more than two browser tabs open, the PC would crash.Installed two of these fans and the graphics card and motherboard are now operating around 40 - 50 degrees under load.The packaging was minimal, which is great for the environment, and the install was easy. I flipped the fans the opposite direction by inserting a narrow, flat-head screwdriver under the frame and using the screwdriver as I pry bar while simultaneously depressing the tabs which attach the frame to the fan body with a secondary screwdriver - you'll understand when you look at the units. Even with flipping the fans, install, including powering down and rebooting the PC, was less than ten minutes.Although there was a mild whirring sound, that soon faded. In fact, I no longer heard the fans after a couple hours; probably I had become inured, but it was a fairly quiet drone, nothing annoying.Purchased two SATA to LP4 adapters to power the units, an additional $14 total, with my entire outlay being less than $35. My system no longer crashes due to overheating components and my graphics card will easily last a few more years.Highly recommend the seller and these specific fans. Even if you've never cracked a PC case before, these fans are easy to install.
