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

Moves more air than I expected. It does make some noise, but it is mostly the sound of the air being pushed through. The fan motor itself is quiet. I added this to help cool down case temperatures while gaming. Goal is to add another path for the air to flow from the front case inlet fans and exit out the back. So far it seems to be helping!

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.

If you have a hot videocard that is not a blower this thing can really work wonders, very powerful! But running at full speed it is noisy and likely will not last as long as it could. Get a Molex to 3-pin adapter wire. You will want to plug it into either a fan controller or a PWM case fan that has a 3-pin piggyback. If the device is speed-controlled by either of those means you may find that it is significantly more powerful than most conventional case fans and not particularly loud for the amount of work it gets done. I highly recommend this for any conventional ATX/MATX case but with a dremel you can even fit it in that grill to the left of your PCI slots and the mounting bracket does come free from the fan meaning you can change its direction. This configuration instantly took 10C off of my peak GPU temps. A more complete kit would get five stars from me but I absolutely do not regret buying! Be aware that you might want to rethink your fan layout after adding this because it will likely create a negative pressure environment and this means more dust in the case. Upgrade to the best intake fans you can find and you'll be glad you did. If the day ever comes that they make a PWM version of this unit I will buy several of them. Please make a PWM version!!

Works great. Installed below my gpu. Def keeps the heat down. Not too loud either.

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.

This is what I needed. EXACTLY what I needed. I have an IBuyPower built gaming computer that's a couple of years old (A great computer by the way). I've been updating/upgrading it recently and needed to find a way to cool it down internally. I was going to install a couple of internal fans to move the air around and one external fan to blow the cool air into the cabinet itself. I jumped online to price things out and saw this StarTech Slotfan so I thought I'd give it a try. It's doing the job and doing it very well! I've only had it installed for several days now so if anything goes haywire on the ol' 'puter because of it I'll post another comment but I don't see that happening anytime soon. Now the specs... I have a gigabyte motherboard, an R9 level GPU, 16 gb RAM, 2TB HDD, Rosewill 850 W power supply and a bunch more I've tinkered on and upgraded, Windows 10, the entire BF series (except Hardline), Titanfall, Inquisition, etc. and before the fan it warmed up fast... after the fan it stays below the high threshold. It's a bit noisy but not near as noisy as the external fan I was using to keep the whole thing cooled off in the interim. I noticed an immediate 7-10 degree (F) drop internally. Which is good! Long winded but there's my review... I recommend getting it if you're looking for a cheap, simple resolution to controlling the internal heating of your computer.

This fan moves air very well. This unit is also very loud. It was louder than tri-cool 120mm and 92mm blue fans. I ended up removing power from the unit because it was louder than the other 5 fans in my case combined. If you NEED cooling then this will help to get front to rear airflow added to your case. If you have other case options then I suggest using them first. For graphic card overheating issues you should add internal fans in the case to move the hot air away from the graphic card. This can be done by adding a fan to push extra air across the cooling fans of the graphic card. Using the "pull" system of this rear exhaust fan to take away hot air from the card is very inefficient. First task is to cool the card then the second task is to remove the hot air. This fan will remove the hot air from the case. Try using a dual 70mm card slot fan or a fan pointed at the graphics card to push air into your graphic card. I used the vantec card for that purpose.

Does well for its size. Compact to fit most anywhere. Take note on where the fan is located so that you're pulling heat out from the space in your case and not blocking the fan up against anything else.
