Havit HV-F2056 15.6-17 Inch Laptop Cooler Cooling Pad – Slim Portable USB Powered (3 Fans) (Blue)

Very Nice Cooler but not for Gaming or Heavy CPU Use
I bought the Havit HV-F2056 Laptop cooler and was pleasantly surprised by how nice it fit under my Lenovo P15s LT. My only complaint is that the supplied cord is a bit short, but one can easily order a longer one for a few dollars on Amazon.For general use, internet browsing and so on, it works very well. Exceptionally quiet and provides a decent amount of airflow. I don’t care for the blue LED’s, but they are hidden under the laptop so it doesn’t matter.However, if you are doing anything that max’s out the CPU speed or the number of CPU cores used, then this unit is not your best option. I am keeping it anyway for day to day general use because I like it, but purchased another cooler for when I am doing intensive CPU work.Liangstar (on amazon) has one with 6 fans, 3 larger ones, and 3 smaller ones. The controls allow you to set the 3 larger fans on, the 3 smaller fans on, or both sets on at the same time. The specs in the ad tell you the # of RPM of each fan (how fast the fan rotates) so you can get an idea of its cooling. The higher the RPM’s, the greater the cooling in general.The Liangstar fans are (3) 1400, (2) 2200, and (1) 2600 RPM, compared with just (3)1400 RPM for the Havit. So one could expect maybe double the cooling from the Liangstar unit.I am using a utility program written by CPUID (a very well know software company) that measures several of the temperatures inside the CPU and on the motherboard. My CPU was running at 95 degrees C with no fan, about 87 degrees C with the Havit, and we will see what it does with the Liangstar unit when it arrives. This is with very intensive optimization routines that max out the # of cores and CPU speed and in an office environment. The temperatures run much cooler with the Havit cooler running when doing more general work, such as using Word, Excel, PowerPoint or just browsing the internet.Generally speaking, the hotter electronic components are running, the SHORTER their lifespan so keeping everything running cooler inside the laptop will definitely make it more reliable and have a longer life.The Havit HV-F2056 is a recommended unit for general computer work.RegardsBobztEngineer

A well performing, no nonsense cooling pad
I’ve had this cooling pad for around 6 months now. Here are my thoughts,The cooling pad itself seems to be of decent quality. The box includes two rubber pads that you have to stick onto the pad surface to help prevent your laptop from sliding. Unfortunately, the perforated aluminum face causes these pads to slide out of position over time. A better design would have the pads pre-installed.I opted for the blue color. I like the look, but there’s no option to change colors or even turn off the light, which may become distracting while using at night.The fans seem to be of good quality. They spin fast enough to effectively cool my laptop while gaming, but slow enough to be pretty quiet. It would’ve been nice if this pad had the ability to adjust the fan speed, but for what it’s worth, I think it’s been set just right for my use case.On the back of the pad, there is one USB to power the cooling pad and another USB for passthrough. I haven’t yet tried this for data transfer, but I can imagine it’s not ideal. The included cable is, at least in my case, way too long, since my laptop has a port directly above where the cooling pad connector sits. For some people, this may be helpful, but you may want to consider getting a short cable.The pad is easy to use, lightweight and fairly comfortable in my lap during long sessions. The pad also includes two risers at the bottom for adjustment, which may come in handy for some.Overall, when you consider the excellent cooling capability, the lightweight construction, and then the price, it’s honestly a good value. It’s missing some features that you may find on more premium cooling pads, but it still has everything you need to keep your laptop from turning into an oven and that’s good enough for me.

I purchased this a while ago and wanted to give it some time using it before writing a review. It has now been years and this little gadget is still going strong. It definitely works wonders in keeping my laptop cool. When it sits on the table it feels really hot but as soon as it goes on this cooling pad it cools right down. I highly recommend. It will help keep your laptop going strong for years.

It works just fine. Cools off my new Dell Plus DB 14250…. surprised me to find it can get warm, not even a gamer ..I like not losing a port, the onboard one functions just fine for me, with a non powered hub. Not soft..not loud, but you can hear it running. With a video on, not so much, but there’s a definite small wind hum when it’s quiet and the wind blows out the front end somewhat on my set up…so the on/off is handy, because it gets used a lot. But the USB A out port works great without the switch on.It’s like a wire mesh type deal….not cheap but not heavy, solid enough…your laptop might slide off a bit like my bigger laptop did ..without the rubber stops in..those help a lot .. I hope to get 10 years out of this like my wooden one with no switch did.I like having the back raised up a bit..the set non height adjust is perfect for me. You get flat, or elevated , no in-betweenThe video gives you an idea what you get here .Works for me
