KLIMCool Laptop Cooler with Vacuum Fan - New Version 2024 - Gaming Laptop Fan with Display - Temperature Detection + Automatic/Manual Mode - Portable - Compatible with Laptop Cooling Pads - Blue

This is an early review, and so far I'm happy with the 2 of these I bought. My only complaint is that these don't turn on with the laptop, and that there is no Fahrenheit option.The major, significant TL:DR is that on modern gaming laptops that are subject to aggressive thermal throttling, the measure of success for your cooling strategy is not "significant temp drops" but increased watt draw by the CPU and GPU at the same operating temp or a few (5 deg C or so) degrees cooler. These Kilm fans, if you get a good fit, are great for this.I had 2 of the Opolar coolers I got with a sale, but the issue with those is that current high end gaming laptops are not uniformly flat on the bottom, and many of these computers are venting heat from the back, under the monitor lid. While the gripping feet on the Opolar coolers are ingenious for computers they fit on, for many rear exhaust computers the monitor lid will compromise the mounting.So there are three scenarios I'll lay out where you may thing you want this device:1) MacBook or Windows/Intel Surface format ultrabook: these computers invent new svelt places to exhaust heat from tiny high-speed fans. Additionally, the ultra book hinge may be a 1 piece design. Ultrabook processors use aggressive thermal throttling to avoid overheat situations, but are usually too thin to mount one of these coolers. It would be better to raise these computers up a bit so air can move around them properly. If you want to try a fan, a silicone baffle that is shallow and narrow is included with the Kilm. But your mileage will surly vary.2) Older laptop with 1 or 2 side exhaust vents: These previously traditional laptop designs mounted the motherboard with the cpu facing up underneath the keyboard and then dumped the heat to the nearest side exit. Some of these older computers have passive thermal throttling or at best a BIOS coded overheat cut off temp set to keep the laptop from melting down. The Kilm and Opolar coolers have rave reviews inches use to allow an older computer to serve a bit longer. Cooling pads also work great with these older laptops as fresh intake air was expected to come from the bottom of the computer, and usually does.3) Contemporary laptops with discreet graphics: The addition of a GPU to an already cramped laptop chassis meant some new and unusual gimmicks to cool the performance beast down. Notably, motherboards are mounted cpu and GPU side down, and close to the rear of the laptop. Any reasonable entry and exit for air will be utilized. I run an Asus A15 with an AMD processor, and heat is an issue, but not merely for wear and tear. The Asus also draws air from through the keyboard and passively from the bottom of the plastic chassis.On gamining and high performance laptops, as well as ultrabooks, processor and GPU speed ceilings are hard coded to the speed your fans to. Choose the Silent profile, the fans run unnoticed but the processors are capped. Choose Performance, more heat, more speed, louder fans. Choose Turbo, max speed, massive heat exhaust, loud pitchy fans.What I use 2 of the Kilm coolers to do is to draft the exhaust from the GPU and CPU heat sinks at the rear of the computers so that can run the Asus in its Turbo fan profile, allowing the processors to run at maximum speed and wattage draw without throttling (suddenly slowing down) while gaming. Because the heat is being pulled from the heatsinks more quickly, the internal fans run MUCH slower and allow my girlfriend to think in piece or for us to conversate at a normal volume. When my laptop is running GTA or Red Dead Online, the Klim fan at the GPU exhaust runs at 3600 RPM and the CPU exhaust fan runs at 3400 RPM. If the GPU and CPU process a demanding load (initial game start or stage changes for example), both Kilm fans are set to auto and will briefly run past 4000 RPM to respond to increases in exhaust temperatures and the quickly quiet down when the loading is done.The important thing about measuring the success of these exhaust coolers on contemporary gaming laptops is not significant temp drops at the cpu and gpu but increased watt draw at the same safe operating temps. Chip makers sell their products with expected efficiencies and specific temps. If a chip is too hot, the laptop will throttle down until the chip cools, with not user input and in a laptop few ways to override this behavior. So if 65 watt GPU runs safely at 80 degrees Celsius, i want that chip to draw 65 watts at 80 degrees instead of 55 watts at 80 degrees because ill get faster and more stable framerates atthe higher watt draw. This Kilm (or even the Opolar one) cooler is perfect for achieving this as long as the cooler fits and doesn't impead opening the monitor lid.On most of the current gaming laptops, there are entirely too many passages for air entry to ever achieve the vacuum effect that Kilm states is optimal for their product. Its is also why on these computers you are not going to see 20 degree F or C temp drops by attaching on of these fans. So don't fall for the slick marketing copy, from any laptop fan product. But if you want your laptop processors to run at maximum wattage without the chassis fans screaming, I can recommend these fans.Will update as I go.

Got this for my grand kids.They say it helps with keeping their gaming lap top cool.packaged well

This is FANTASTIC! I have tried SEVERAL laptop stands with fans for my gaming laptop. Nothing EVER kept it cool. I even recently spent waaaay too much on a metal one that promised almost "air-conditioning" quality but failed miserably. I saw this by chance (thank you Amazon algorithm :-) and saw that one person said it worked great and seemed to have a laptop like mine and said he bought 2. So I ALSO bought 2 and LISTEN!!!!! This has kept my laptop the coolest it has EVER BEEN since I bought it!!! I am so amazed. Just even as I type, it's sooooo cool to the touch I am flabbergasted. BUY IT!

I contacted the company before writing this post. Their response was as disappointing as this product. It doesn't work. I've stacked cd cases under it so it can be the same height as my computer. The plastic bit that sticks to your computer doesn't. The auto-fan must be switched to manual so my computer won't get so hot. It was a great idea but it needs more work. When I emailed the company about the various problems I've had I was told they will keep them in mind for future releases... Seriously? Perhaps we should all wait to buy this until they get the bugs worked out?Update:8/9/16I received a replacement, the fan was slower than the previous one the response from Paul was:"It's the big weakness of our product, its effectiveness varies quite a lot between different models.As far as the speed, it depends partly on the air outflow, the more powerful it comes from the laptop the faster the KLIM Cool will be able to go, that being said 3650 is normally sufficient for decent cooling, unless your model is not compatible as seems to be yours.I apologize for the unsatisfactory experience, unfortunately it seems our product didn't meet your needs but if you could change your review regarding the customer service it would be greatly appreciated!Best regards,Paul"I am concerned that the company knows their product varies from models (this was the only model when I purchased it) and their big concern is me changing my review about their customer service!Ok they emailed me back and sent me another product that didn't work (I was offered a refund or replacement product, for the one that didn't work). So as far as customer service goes, they do write you back & offer to replace or refund. As far as the product my Dell computer which has a side vent as it is a gaming computer isn't being cooled by this product.Paul isn't just some customer service flunky as it is my understanding he is one of the owners/inventors.I'm still not recommending this product.8-10-16This morning due to the owner/inventor Paul not liking my update from yesterday (I refuse to give a glowing 5 star review about a product that doesn't work & lie about what has been said by the company) wrote me a rather snarky email. I've written mostly 5 star reviews unless something doesn't work or something is seriously wrong. People that behave as this individual has I don't do business with. If he continues to email me asking me to change my review or with the snark I will contact Amazon & have a chat about Paul.

It’s too heavy to be mobile or elevated at all, so no matter what it has to be on a permanent flat surface. It works, but not great, you need at least two of them for it to not get too overheated. Also, the adhesive is not sticky at all causing loss of suction. It’s okay but at this point I’d rather stick with a cooling pad

This is a nice unit and is good at keeping the computer.I loved the little "extra gift" that was included; sure makes you feel like your order is appreciated and that customers are important to you.Thank you 😊
