KLIMTempest Laptop Cooler with Vacuum Fan - New - Gaming Laptop Fan with Display - Temperature Detection + Automatic/Manual Mode - 4000 RPM - Portable - Compatible with Laptop Cooling Pads

A few years ago I bought a nice gaming laptop. For the first time in my life I was turning graphics UP, rather than cranking them all the way down so they would be playable. Over the years, the laptop began slowing down... frame-rate drops at first, and finally games would slow down so much that they were completely unplayable.Since my laptop was getting hotter than the surface of the sun, I suspected heat was to blame. I bought all kinds of products - a lap desk with fans, I made sure the fans were dusted out and working, the works. I downloaded software which would allow me to throttle certain functions of the laptop to reduce heat... but then it was a race between how much the software was throttling my laptop and how much the heat was causing it to throttle itself. There were some games I gave up playing entirely, simply because they played so slow it wasn't worth it.One day, I happened to see the Klim Tempest on Amazon. Very cheap - only $30, and claimed to be universal fit. I figured, what the heck.. let's try it.And now, my laptop runs... almost like new.The Klim Tempest is a miracle device. Rather than lap desks which simply blow little puffs of air at the bottom of your PC, the Klim Tempest attaches to the exhaust ports of your laptop and literally SUCKS the hot air out and shoots it out the back. I have no clue where the less than exemplary reviews I see are getting their experiences - some say the fan isn't very powerful? Maybe you're just installing or using it wrong? When I hook up my Tempest, I can put my hand over the back of it and feel it jetting out hot air.Games that used to heat my PC up to the point that I almost couldn't touch the metal surfaces... now my laptop maintains temperature and performs as it should. No more burning hot laptop.. just high-end performance. I can once again play my favorite games - games that would overheat and slow my laptop to a crawl within minutes.The Klim is quiet and powerful. You can hear it spool up when the laptop is heating up, but trust me, if you're playing games, the sound effects will WELL overpower the sound of the Tempest - you won't hear it. You'll forget it's there.The mounting mechanism is a bit awkward. I have to be honest, I wish there were a better hook-up.. but the designers were trying to make it as universal as possible, and on that front I feel they did a good job. It might take you a few minutes or a few tries to find out what works best for you, but I've found a way of setting it up where it doesn't slip off all the time, so I'm good. Maybe in the future there will be better mounting mechanisms. Four stars out of five for being a good balance between working and usable on all laptops.It functions EXACTLY as it should. You can download software to monitor your laptop's heat level, and download software to run a stress test - give it a try: hook up the Klim Tempest CORRECTLY, (meaning make sure the seal gaskets are closing off that exhaust port and the hot air will be going exclusively into the Tempest), run a stress test to build up heat, and watch the little device work its magic.I could not be more impressed. If you find your laptop getting extremely hot and performance degrading significantly, THIS DEVICE MAY BE THE ANSWER TO ALL YOUR PROBLEMS. I can't guarantee that (you might have other issues) But for $30 how can you go wrong!? I can FINALLY play my games again, so I'm so happy.I sent the designers a kind note to let them know how much I appreciate it. They wrote back thrilled to hear that I was happy, and were even asking what kind of games I play - these are people who are not only developing an amazing product, but care about their customers.100% satisfied, would have paid twice or three times the price for the difference it has made. Absolutely amazing and so glad I gave it a try.

The cooler works quite well. Set up is fairly easy and instructions are straightforward. The cooler provides a variety of mounting options. However, make sure before you order this product that your laptop fan exhaust is on the side of your laptop. Otherwise this cooler will not mount on your laptop properly. (I ordered 2 of these fans and set up worked great on my Lenovo laptop but did not work with my HP .) I'm going to keep the 2nd fan as an extra because this is a great product. The digital display is quite useful as you can monitor the changes of temperature on your laptop in comparison to the ambient temperature of the room. Definitely would recommend this high quality cooler with vacuum fan.

Atrocious instructions. I had to go to YouTube to figure it out. Once "installed", it just flimsily dangles there on the side of the laptop. In other words - not by any stretch of the imagination - is this thing firmly attached. Any wrong movement, even if you look at it funny, and it could fall off. It's not ideal in that sense. Having said this though, it successfully cooled down my very old Dell XPS l702x in less than 90 seconds. So, it functions well and the principle is sound. I would say that it cools much better than a large cooling pad for my particular system. This is because it sucks out the heat in a very targeted manner rather than blowing. I don't understand why laptop makers don't have this sort of thing built in from the get go.

great for laptops during charging from less then 50% charge. keeps the battery cool so the battery can charge faster and reduce overall wear and tear on the system. I like it. easy to stow in my backpack and take to campus as well. glad I bought it.

the KLIM Tempest Laptop Cooler helps keep your laptop cool by using a vacuum to pull hot air out of your laptop quickly. I use it in tandem with a fan-powered laptop cooler under my laptop. The KLIM has 13 speeds to control the amount of vacuum pull. Installation is fairly simple, and as long as you are able to get a good seal on the side of your laptop to the KLIM, it should pull hot air out nicely. Even at the most demanding tasks on my GPU, the combo of the cooler fans and KLIM keep my laptop at around 100 degrees F.PROS: Creates a powerful vacuum to pull out hot air; effective at its purposeCONS: Needs a good seal to the laptop to be effective, which may be an issue for some laptop designsCan get a bit noisy at higher settings

Honestly, I'm not upset with the order. Worth trying out for yourself. The device is well designed, but I don't feel on my high-end gaming laptop MSI Katana 15 during "heavy gameplay extreme heat" is getting a benefit of pulling hot air out. This might be that the laptop has a high speed fan countering the benefit of having the vacuum design of this product canceling it out. The temperature would just drastically go up on the device overtime - I just didn't feel the benefit there. However, I decided to point the cooling fan towards the entrance vent of my laptop on the backside to help push cool air in. It's actually keeping that area of my laptop cooler to the touch! Overall glad I have the product, I'm just not using it as originally intended per say. I saw that you can also attach this product to other hot devices - so that's a nice plus.
