Which direction does the air flow to, does the fan suck air out of the laptop or blow air into it?

It sucks air in from the bottom and blows cool air onto the base on your laptop. It has two legs to elevate the back for more air flow.

The fan blows up at the laptop. In my case it doesn't blow "into" it, as there are no air intake vents on the underside - but my laptop has metal underneath the plastic across the entire bottom of the laptop, presumably to spread the heat, and this helps dissipate that quite well.

The fan blows into the laptop. And indeed, as E. Borah said it helps dissipate the heat very well.

It is on the bottom, which holds the laptop off whatever it is setting on. Seems to me that would promote better air flow!

Well all fans blow air in one direction... It's how you install it. You can install them facing in or out this is a standard with computer case fans.

The laptop has inlet vents on the bottom and exhaust vents on the top, so any air you pump into the bottom will increase the flow through all of the pathways. That's just how the laptop is designed. This has one large fan I the middle, which will definitely force enough air through to make a difference in all sections of the laptop.

It blows/pulls air off of the bottom of your laptop, thereby removing heat from the bottom. It works well if your laptop fan exhausts out the back. You'll feel it on your legs if you're wearing shorts.

pulls the heat down and out the sides, the bottom is solid, there are two twist knobs that open up the center for the air to flow out. So far, THE Best Laptop fan I've ever owned, and this is my 4th one.

Chances are it pushes less air than you're default fan, at least it did for me . I was debating between a new card or new fan, i should have chosen a new card because I've had to buy one anyways

Neither. The air does not flow in or out of the PCI case slot. The fan throws the air onto the PCI card next to it. In other words the air flows from the side shown in the picture to the opposite side keeping it all within the case.

You can mount this fan either way. Look for the molded arrow on the side of the fan to identify airflow direction. Its most efficient when it pulls air through the computer chassis and exhausts it out the back. If you plan to mount it to the side of your chassis to cool your CPU you'll want to bring cool air in from the outside.

I use my laptop while sitting in my bed or on the couch all the time. I've never had a problem with the vents getting blocked. It seems to circulate pretty well, sometimes so well that I don't have to plug the fan into my laptop (the extra space between the laptop and whatever surface I'm using is sometimes enough for the laptop's fan to circulate hot air away without the help of this fan, though I tend to plug it in after I've been using the laptop for a while).

There are two small fans (80mm) on the lower back part of the case that can be configured to blow air to or from the hard disk trays. In my setup I have installed two Noctuas NF-R8 redux-1200 and all my 4 HD's runs cool and quiet.

i own one i have never had any issues with the cooling fan, but there might be a defect.if you are setting the laptop on a hard surface and have an issue then there is a problem, but if you are setting it on bed,couch,clothe any no hard surface, that is the problem.check the cooling fan and the vents if they are clogged with dust vacuum all the dust of see if that helps, might have a defective part.

They designed this fan so that you can optimize the individual fan orientation to your liking. Although it can be somewhat limited you are able to freely adjust the fans' placement to your liking. If I were you I would change the fan position to cool that are of your laptop more effectively but ultimately it's up to you what you do with it.

Has a dual fan that forces air up to the bottom of the laptop, which makes sense because the fan on the laptop draws air from the bottom and exhausts it out the side or back. This way the fans work together and not against each other.

You should pull air out of the back of the case. If you look on the edges of the fan there are arrows that indicate air flow direction . use this to help you install.

It draws air up through the units fan to blow onto your laptops fan. My problem was this unit's fan is in the center and my lap top has it's fan to the left. While it did cool my lap top down a couple of degree's it was not nearly as effective as other unit's I have had.

You plug in you computer laptop to AC power. It uses one of the laptop ports for the fan and expands more ports on the back. Use the USB3 to power it so all the expansion are USB3. I use one lap top port for it and one for a USB light. Remember, if you use an attachment when you have it portable, to move any USB on the cooler to the lap top, unless you are taking it with you. You just have to make sure your carrying case is large enough to accommodate the cooler. If you have ever seen some one loose their lap top computer from laying it on their lap or bed where it can not cool itself, you will know why I bought this.
