havit HV-F2056 15.6″-17″ Laptop Cooler Cooling Pad – Slim Portable USB Powered (3 Fans), Black/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

Quiet, Effective, and Truly Worth It — A Cooler That Delivers for Work and Play
This Laptop Cooler has become a staple in my workstation and gaming setup. Slipping my laptop onto it feels like giving it a breath of fresh air. The triple-fan design really does make a noticeable difference in surface temperature, helping prevent overheating during long sessions.What really impresses me is how quiet it operates. Even under load, the fans hum softly without competing with my keyboard and game sounds. The slim, lightweight build makes it easy to carry between rooms (or even to a coffee shop) without adding bulk. It’s USB-powered, so there’s no messy extra cable. Just plug it into your laptop and go.On the few occasions I’ve pushed my machine with rendering, heavy multitasking, or gaming, the cooling pad helps keep performance more consistent. My laptop remains cooler to the touch, which feels safer for internal components over time.If I have a slight nitpick, it’s that on extremely soft surfaces (like a thick blanket or cushion), the airflow isn’t as effective. But that’s a trade-off with all external coolers. For desk use or on firmer surfaces, it works flawlessly.In short: this cooler works just as well for work laptops as it does for gaming rigs. For anyone looking to preserve performance, reduce heat stress, and keep things quiet, I highly recommend this with confidence. Very easy to use, easy to clean, and durable. I’ve used this for several years without any issue.

No es un secreto que a todo portatil le llega su San Martín en cuanto a los problemas de calor se refiere, sobre todo en verano. El prolongado funcionamiento y la compresión de espacio en su vientre hace que el procesador y el disco duro alcancen temperaturas excesivas y provoquen malfuncionamiento e incluso el degradado de la pieza (dispersión de pasta térmica, etc).Me decanté por éste modelo, principalmente por su tamaño adaptable a mi portátil de 15,6”, sus 3 ventiladores (mirar siempre que os coincidan con vuestra rejilla de la carcasa para mayor efectividad), y su “ergonomía inclinable” (unos 20º aprox), no resbala y la rejilla mantiene el equipo bien sujeto. Además, tiene un puerto adicional USB para no perder el que ya se usa para su funcionamiento (aunque lo mejor es usar un HUB para ampliar puertos). Es muy liviana y menos aparatosa que otros modelos más robustos que he visto.El resultado es una base que refrigera el interior del equipo, unos 12-15 grados aprox según marca mi monitor CPUID, en rendimiento normal, y unos 8-10 grados en alto rendimiento de procesador y gráfica. Suficiente como para que ventile mejor gracias a la inclinación de la base, y para no “quemarme las manos” al escribir sobre el teclado. Se nota mucho. Además, es ultrasilencioso, hace menos ruido que los discos duros externos que tengo. Cumple su cometido para bajar apenas unos pocos grados la temperatura habitual.Como curiosidad (ni buena ni mala, según gustos), desprende luz azulona mientras está en funcionamiento (tipo “gamer” llegué a leer), que si es cierto no se puede elegir que luzca o no, pero que no supone ningún problema, ya que cuando hay luz apenas se nota, y a oscuras ilumina los laterales de la mesa, como el ratón por ejemplo. Vale, no es ideal si vas a ver una peli por el efecto “ambilight”, pero no deslumbra la vista tampoco. A mi no me molesta.Muy recomendada.

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.
