KLIMTempest | Laptop Cooler With Vacuum Fan | Innovative Design for Rapid Cooling | Temperature Detection + Automatic/Manual Mode + 4000 RPM | Compatible with Laptop Cooling Pads

Love this! Works extremely well on its own or in conjunction with a pad-style cooler. The temperature display lets me know when I need to up the rpm for increased cooling. It is very satisfying to watch the temperature drop once it's been activated. All of my laptops over the last few years have had heat issues that they weren't able to deal with. I wish I had this gadget earlier as it would have saved me some true heartache. It is a little noisy but I consider it a minor inconvenience and well worth keeping my laptop cool. The compact size makes it great for travel purposes...no need to lug a cooling pad around. You have to be a little more cautious when moving your laptop around but it beats having your laptop die from a warped motherboard.

It makes sense that instead of trying to push air through the bottom of your laptop with a cooler pad (although I do have one of those as well), using a method that sucks the hot air out of your laptop, and thereby pulling cool air in is a better solution.I bought the Klim Wind cooler pad and this Klim Tempest in the hopes of cooling down my overheating laptop that kept crashing on me with the blue screen of death.The Tempest is easy to set up (I have stuck mine onto the cooler pad) and it is whisper quiet, much quieter than my laptop fans which seem to not run so much now.I love the auto setting, which monitors my laptop temperature and adjusts the suction if needed. You can set it to manual if you prefer.I have an Acer Aspire V17 Nitro gaming laptop, which has rear facing heat vents on both left and right. I have an aluminium "chassis" on my laptop and since I have attached the Tempest to the right-hand side, this side of my laptop is cold to the touch, not just cool, but cold, even when I am running processor hungry programs.The intake vents underneath my laptop are basically tiny holes dotted all over the bottom. Blowing air towards these vents (by means of the cooler pad), can't do that much on their own, but I believe by having the suction on the outward vents, cool air is more readily pulled through my laptop. In other words, I think the combination of cooler pad and extractor is a winning formula.I am so impressed with this thing, that I bought another one to go on the left side.Ensure that you check whether your laptop is suitable before purchasing, but if it is (as I am sure most will be) then go ahead and buy it. It's great.

I have bought two for a 17" laptop. These two are unacceptably noisy, I regret the purchase.Edit: KLIM resolved the issue and sent the substitute. The new fan is silent.Customer support at KLIM is highly professional, friendly and efficient when you need a resolution. They work with you even at weekends.

I've had one of these hooked up to my MSI gaming laptop 24/7 for the last 3 years and it's been working perfectly.

More efficient then my laptop cooling pads and far quieter.The auto temperature sensing for the fan speed is useful as well, so it only revs up automatically when needed.

I bought two of these to use on the exhausts of an Acer Nitro gaming laptop, which can get quite warm to the touch on the panel above the keyboard (under which the CPU and GPU lie).System: 5800H and 3070 GPUSystem cooling set to Auto, with Acer NitroSense CoolBoost enabled.Test #1 - CPU Stress Test at default speedPutting things under CPU stress load (100%) and no GPU utilisation other than basic windows, CPU temp was at 90C before I connected both coolers to separate exhausts.After several minutes, everything was still at 90C, so no effect for me whatsoever. Failed on the CPU cooling.No noticeable impact on the temperature of the warm area above the keyboard.-----Test #2 - CPU Stress Test at max speedExhaust fan noise is significantly louder - from quiet at default to clearly audible at max speed.And yet ... still, everything remained at 90C, so no effect for me whatsoever even at max fan speed.No noticeable impact on the temperature of the warm area above the keyboard.-----Test #3 - Gaming at default speedRunning a game, without either CPU or GPU being overly stressed. CPU load ~17%, GPU load ~60%Without coolers:CPU temp 69C, GPU temp 58CWith cooler:CPU temp 67C, GPU temp 56CNo noticeable impact on the temperature of the warm area above the keyboard.Remember that is with not one, but two of the coolers - delivering 2C on both CPU and GPU. Not really cost-effective cooling.-----Test #4 - Gaming at max speedRunning a game, without either CPU or GPU being overly stressed. CPU load ~17%, GPU load ~60%Without coolers:CPU temp 69C, GPU temp 58CWith cooler:CPU temp 67C, GPU temp 56CNo noticeable impact on the temperature of the warm area above the keyboard.So as with the CPU load testing, the fan rate did nothing to change cooler performance, whilst completely cranking up the noise levels.-----I thought at first there may be an issue with the contact on the cooler, but upon a touch test, despite the volume of air going out the back of the cooler (as if its shifting something), there's really no sensation of air flow or suction at the intake - blocking the intake with the length of my finger diminished, but did not remove the air exhaust, so it seems as though a lot of air movement is not coming from the source of the heat, but is ineffective pass-through.Beyond the poor performance:Easy to setup, though would be awkward for use on-to-go. But in theory, not a problem for gaming at home on a laptop which isn't being moved about much (*if* the cooling was actually effective, which it is not).Contents are well packaged, and the units are lightweight.The digital temperature display looks cool (though it didn't reflect the temperaute within the the laptop - the 60-90C internal temperature being reflected about 32C on the digital displays - which is another indication of how ineffective it is at processing the internal heat).

Easy to set, up and remarkably, it stays on the surface pro- very effective- on a sweltering hot day it reduced the temperature of my Surface pro by 8c in a few minutes.

The KLIM Tempest has breathed new life into an ailing and now rarely used HP laptop almost 10 years old. Originally with OS Windows 8 then upgraded to Windows 8.1, I further upgraded it to Windows 10 and it's been running hot (and slow) ever since.KLIM Tempest has certainly solved the temperature issue but I don't think the limited-time free upgrade to Windows 10 was a good idea from Microsoft.I might just get another KLIM Tempest to save moving it around. It works well and looks good - and is quiet.
