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

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.

I'm neither gamer nor road warrior, and my relatively stationary customized, non-OEM laptop sometimes runs warm, noticeably during sustained use or when recharging. (The laptop vendor said, "That comes with the chip," and I couldn't rightly argue.) This device looked interesting on paper and in pictures; I'd to date used an NZXT Cryo LX that appears no longer in production but is undeniably sturdy and demands a non-USB power supply.You can indeed hold this device in your hand and pocket it. Simply slip the appropriately sized silicone shroud (a choice of four sizes) over the device intake and do your best to mate that with your laptop's primary exhaust vent, plug the device into a USB port for power, and turn it on. It lights up in blue and a four-digit number displays that appears adjustable with the twist of a knob. (On this run the number varies but stabilizes in the high 2200s/low 2300s; I infer that means RPM, and no real need to run that up yet.) Runs quiet enough. No software involved.But...does it truly work? Time will tell, and on the question of power usage and durability as well. I'll update this as the need arises.(UPDATE: It helps to keep the device intake level with your laptop exhaust vent, and Klim provides plenty "shivs" to support the device. I've also since determined that it demands a non-USB power supply. If I can find a suitable US5VDC-AC adapter and cord plug I'll report same.)(SECOND UPDATE: And the winner appears the combination of a Dericam 5V 1000mA AC to DC Power Adapter with an [I]BERLS Universal 5V DC [5-foot] Power Cable, USB to DC, 5.5 x 2.1 mm [its default] plug. Still something of a juggling act, though, and I'll see what results of prolonged use.)

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!
