ThermaltakeMassive V20 Steel Mesh Panel Single 200mm Blue LED Fan Adjustable Speed Control 10"-17" Laptop Notebook Cooling Pad CL-N004-PL20BL-A

I was looking for a cooling solution for my Asus AC3100 router and this did the trick. Generally, you don't need active cooling for a router. As long as a router is located in an open area where air can circulate, it'll be just fine. Most newer router CPU's are designed to operate at temperatures between 70-80 degrees Celsius and even slightly hotter with little trouble. The problem I had was that the interior room in which I keep my router is always warm. Even though I keep my router in the open, the ambient temperature of the room drove up the router's CPU temperature, which routinely hit more than 80 degrees Celsius during heavy use (gaming and streaming). That's something the computer nerd in me needed to fix.After see a bunch of fairly ugly hardware hacks, I figured a laptop cooling pad would work. This was inexpensive enough to try out and it did the job. The single, large fan more than covers the footprint of my router and feeds air into the vents on the router's underside. Within fifteen minutes of positioning the router and turning on the fan, the router's idle CPU temperature dropped almost 20 degrees Celsius. CPU temperature now hovers between 49-55 degrees Celsius even under heavy use.At full blast, the fan is fairly quiet. I'll notice slight noise if everything in the room is quiet from about 10 feet away, but it's certainly not overwhelming or disruptive. I've never operated the fan at less than full speed, but you can adjust it. Lowering fan speed all the way shuts the fan off. The unit runs off of USB power, but I have it plugged into its own outlet using a mobile phone adapter. It absolutely can be powered by my router via USB port, but I'd rather avoid the potential interference doing so may create. The LED lights can be shut off if they're not your thing. Note that the entire unit does have a somewhat large footprint and works best on hard, flat surfaces. As with all active cooling fans that suck in air from the bottom of a device, do not place the unit on carpet. That's just asking for trouble.If you have a router that runs a little too hot and your router also is ventilated on the bottom, this will do the trick. Inexpensive, well built, and quiet.

I got this cooler for my Lenovo Y40 14 inch cos it’s battery had to be changed couple of times due to quick wear-out (thankfully I had 2yr extended warranty). Since the Y40 was coming to the end of warranty and usually battery wear has something to do with the heat, I bought this to keep in my office (I had another brand cooler for home too).In short:Pros:- Well built, especially for the price- Barely audible (if any)- Blue LEDs (although they’re hard to see when there’s a laptop on it)- Adjustable fan speed- LED on/off buttonCons:- Maybe a bit small for any laptop over 15 inchesUsed it for some months now, so far so good, just working as it supposed to be. Only change I had to was adding a USB cable extension (since I was plugging it to my external monitor instead of the laptop itself. But if you plug it to the laptop cord length is more than enough).Since its only one large fan it is supposed to be quieter than ones with multiple small fans. TBH I’ve not noticed it working (and my office is not a noisy place either).Only concern I can think of is the size; although they advertise it “Compatible with 17" notebooks and below”, even my 14 inch Y40 is almost the size of the cooler.Anyway, I’ve moved to an Alienware 13 now and the cooler still fits and works fine. I’ve not done any extensive testing with measuring temps with and without, but will update if anything goes wrong.Especially for the price, I cant think of anything bad about it.Please click the ‘Yes’ button below if my review helped you. Thanks!

Honestly, for gaming laptops this cooler pretty much useless even at full speed. The fan is not powerful at all, and the effect that this has on temperatures while gaming or doing even regular tasks is almost nonexistent. This is one of the cases where you get what you pay for I ended up buying a more expensive cooler and it is 100 times better than this. Don’t waste your money.

The 200mm adjustable speed fan provides a great deal of cool air - keeping my laptop cool under load. I keep the fan around 30% speed and that keeps my laptop cool. Very low dba.However, my 17" MSI gaming laptop is a bit too big. The feet on m laptop are only half on the edge of the cooler. My laptop slips around.I used some Scotch brand bumpers to make contact with the underside of my laptop to keep it in place. Cheap and effective solution.I also use this same type of cooler with my HP EliteBook 850 G6 - 15" and that is a very good fit.
