Pros: It is great if you modify it to be put above your GRU and blow down on it. That way it cools your GPU from the top.

Cons: it takes 2 PCI express slots. but I just used tin snips and cut the useless exhaust one off.

Pros: I used this as 2x case fans. I wanted the splitter.
* 400-1450 RPM (within 10%)
* Slim design allows them to fit within top space in the Bitfenix phenom mATX, allowing for multiple GPUs easily.

Cons: * A bit louder than advertised at max speed. Not significantly louder, low hum.

Overall Review: Screws provided were good for PCI mounting, but I would have preferred that screws provided were good for case mounting as well. There are 2 long screws for the PCI bracket to fan, and 4 small screws for fan to fan.

Pros: These are almost comically thin, I didn't use them as gpu coolers but I have a spot on the bottom of my case and these were perfect to suck air and not get in the way of wires, oh and they come with long fan screws, like twice as long as normal ones

Cons: If possible they could be thinner, I guess they work for some people under the gpu but I have a crossfire setup and it doesn't fit between them or under because the plug for the internal usb 3.0 is in the way on my mobo, but this wasn't the reason I bought them for to begin with

Pros: the half profile lets them fit in tighter spaces where I need them to

Cons: they're probably the loudest fans I have, and I have some serious fans. The pci slot mounting bracket is a double slot which makes them nearly impossible to mount in a pci slot in my system because I only have one open slot at a time

Overall Review: I would've appreciated other mounting options or if the included pci bracket attachments had been drilled on both edges, they also could be slimmer, half profile is nice but I know there are even slimmer designs out there

Pros: Two near silent 120mm fans seated directly adjacent to one another provide a ton of airflow, comparable to dual 120mm fans on a GPU cooler. This product can and will replace a GPU fan, provided that you have a heat sink and room to install, and it should reduce temps or at least provide equivalent temps depending on "how good" your card's stock cooling is. They move air upwards in the case, although I believe you could just flip the fans over and screw them in like that if you needed downward airflow (I don't know if that would compromise the integrity of the fans, so do it at your own risk).

Cons: It's quite flimsy once it's been installed in the PCI slot and hangs down slightly towards the end, however it does not move once set in place and the fans kick in so it's not an issue unless there is a cord directly underneath it or something like that, which can be moved anyway. Not enough to take away an egg

Overall Review: My HD 7870 fan crapped out so I took off the plastic fan housing and re-attached the stock heat sink and then installed this GELID slot fan underneath as an inexpensive cooling solution (25 bucks instead of 50 for a whole new VGA/GPU cooler and avoiding a complicated installation). It brought down my standing GPU temps by roughly 6 degrees and brought down stress temps about the same. I almost bought the Vantec dual 70mm fan PCI card, however the reviews indicated that it was very loud on high settings. I was in need of a quiet solution because I have this installed directly below my HD 7870 as a GPU fan and it works fantastically even under 100% stress. Best of all, if/when either of the fans die, I can simply buy another low profile fan and screw it into place! Keep in mind that it has a 3-pin adapter that must be plugged into the motherboard, so your GPU will not be able to monitor speeds if you have fan control software for the GPU. On the other hand, you should be able to control it with any Motherboard fan controls with all the rest of your system fans! Otherwise I believe it will just run on high by default when plugged into the motherboard. It's a great and very simple product that can solve a large number of cooling issues
