Review: Cooling my modem and router - My last cable modem up and died after just one year, I'm pretty sure because it got so hot all the time. It was a modem+router so extra hotty-hot-hotness from all the circuitry packed into one case. My son thinks this is sort of normal lifespan for routers and modems - he expects only 3 to 4 years. Well I got 8 years out of one of my last modems and 10 out of the other (same modem, WTGS54 whatever that was, it was a very good modem for its time and I got more than enough throughput from it for my needs, including streaming video, I was still running one up until 2 years ago). So *I* was shocked at its short lifespan (especially given the cost, over $200) even if he wasn't. There is just more electronics involved in these tasks, packed into less space, than the older modems. They are GOING to get hot. So in order to keep that from happening again I bought this USB fan kit, comes with 2 fans hooked together, to replace the floor fan I had aimed at the new modem and separate router. I was getting some of these anyway to put on my LED grow lights to cool them (they will ALSO last longer if you keep them cool) so I took one of those and shoved it under the router (because its a flat design, give me vertical any day) and stood the other one up next to the cable modem (which is vertical). I've got them on low and they are cooling both devices very well. On low the router gets barely slightly warm, and the better design of the vertical case for the modem leaves it totally cooled down with this little fan. If I had it to do over I'd look harder for a vertical router as well, its easier to keep them cool. AND they take up a lot less space! I've got a bunch of old computer cases with fans going to waste, I will likely make some USB fans from all those old bits and pieces, but they are likely to be a lot louder. This fan is extremely quiet even on high. I can't hear it at all on low. Also these fans in particular are optimized for humid environments so I wouldn't use anything else in my grow room. A lot of people use the other dual fan kit with the larger fans but they are using them to move air over microgreens to cut down on mold and fungi, I don't have that problem, I just need to cool the lights to improve their longevity, so I'm trying these smaller fans (take up less headroom over the lights, giving me more space under the lights because I can move them further up). I highly recommend cooling your router/modem/game console whatever electronic devices you have sitting around generating heat with some kind of fan, and these are very quiet, easy to assemble (as in plug them in), and very effective. I've seen some people insist that you shouldn't do this because it might "blow dust into the case" - where do these guys live, in the middle of death valley? LOL! Just do it. I've had a floor fan blowing across my very very ancient laptop to keep it from overheating for about 5 years now (even laptop coolers can't cool it enough) and its still going strong. I can even play (very very old) games on it still. Heat will kill your devices WAY faster than whatever tiny specks of dust these fans probably won't blow into the cases anyway. Also, if you have one of those stupid refrigerator closet things where they've built an enclosure all the way around the fridge, that is trapping heat and shortening the life of your expensive stainless steel fridge - you can use these fans to draw hot air out of that too (though I'd go with the larger version for that). Personally I'd tear that crap out but failing that, install these in a side or back wall and pull that heat out of there. Your fridge will thank you. Your bank balance will be the better for it over the long haul.
Review: Excellent fan, very quiet, fixed my slow/overheated PC issues - Excellent product. I was honestly not expecting something that works so well for so cheap. I have my surface pro 4 and dock stuffed into a slim drawer at work, it powers 2 4k monitors and does a LOT of heavy computing so it gets very hot, even the dock gets hot. Of course it doesn't help that it's stuffed into a drawer. It was to the point where the CPU was being throttled and everything was running slow as molasses, and probably causing long term damage as well. I cut out a hole the size of the fan, got some #8 32 2" machine bolts and lock nuts and attached it to the bottom of my drawer. The long bolts were so I could use the rubber mounts. The fan blows outward, there is plenty of air coming in around the drawer. I immediately saw a difference in performance, PC ran as it should be running. In terms of noise, there is none. My office is fairly quiet, but I can't say it's funeral parlor quiet, but still I can't hear any noise at all. The fan is solid, no rattling, no ball bearing noise, and this is at full speed. Air output seems excellent, I can feel a strong output at about 4 inches or so away. My surface pro is cool to the touch so I know it's doing it's job. I also like that it comes with a daisy chain output USB port, so you can daisy chain multiple fans. I initially thought it was a USB bypass, but it doesn't work with peripherals such as a usb mouse. In the instructions it only references it as a fan daisy chain. I'm completely happy, but if I had a wish list I'd say consider making this a usb bypass because usb spaces are highly limited on my surface pro/dock setup. My only caveat, but this isn't the hardware's fault, is that when my PC is locked the fan stays on. That's just how USB works. I'm in search of a program that can allow me to change the hours the fan runs, as I don't need it to run when the PC is locked as it's not being used heavily. I also cannot put the PC to sleep because I need remote access to it, although I have considered wake on LAN as an option. My concern is I don't know how long the fan will last being used 24/7 like this, but even if I replace it once a year it's cheap enough.

### ⭐⭐⭐⭐⭐ Miracle Fans
*by C***R on March 14, 2020*

I just bought a used Onkyo TX-SR805 receiver already knowing that they run hot from reading reviews. When I arrived home I immediately set it up and liked the sound. Within 30 minutes I put my hand on the top of the receiver and could not believe how hot it was. You could fry an egg on it. I knew this was not good. I then noticed that the side vents, one on each side, housed a fan each. The fans were not working. I believe this is one of the reasons Onkyo has a reputation for very hot receivers, inefficient cooling system. Replacing them would probably not be cost effective. I purchased this set of fans from Amazon and set them up vertically at the rear of the receiver, one on the left and one on the right, to push the air towards the front of the receiver and out of the cabinet (I have an audio visual cabinet with doors. I keep the doors open). This setup produced cooling and the fans were powerful enough to push the air out of the cabinet but the cooling was only fair. I was not satisfied since the receiver top was still hot, though not as hot as before. I now proceeded to lay both fans on the hottest sections of the receiver venting the hot air out of the receiver and was amazed at the results. The receiver cooled down so much that when I touched the top of the receiver I felt no heat. I ran my hand across the top of the fans and I felt the hot air being drawn out completely. By the way the setting I have it on is HIGH. I didn't try medium or low since this receiver produced atomic heat. The receiver remained pretty cool with this second setup. I just purchased another set to stand up at the rear of the receiver (as was my first setup) to push the hot air forward away from the front of the receiver, as I plan to elevate on 4 columns (4 black pepper shakers from Dollartree-perfect size-about 1/8" taller than fans) my turntable. It remains pretty stable. As mentioned previously, I have my audio visual components (8 in total) enclosed in a cabinet with doors. There is an open back and the doors swing out and to the side and back, out of the way, making it perfect for my rig. Will probably update with photos once everything is in place. Definitely recommend these fans. Especially for the price. I was going to buy AC Infinity's more expensive setup with the 3 fans that lays on top of the receiver and vents out the rear but didn't want to spend $119 for it. I read in the reviews that it was a little noisy and that thermostat is inaccurate. Two sets of fans for $30 and 4 black pepper shakers from the Dollar tree (come in a set with salt) for a total of $34 Will actually do a better job because you are using 4 fans this way, which can be Daisy chained compared to only 3 fans with the $119 rig. As a former Marine we are taught to improvise and improvising can save beaucou bucks. Wishing you the best and God bless. UPDATE:. Just received the second set of fans and set them up at the rear of the receiver to push the air out of the front of the cabinet. Fan setting is on high for all the fans. Works marvelously! Haven't purchased the pepper shakers yet from Dollartree (was there today and forgot-set it up earlier with two of the shakers-one salt white and the other pepper black-work perfect!) so I have the turntable set up on empty medicine bottles. Supports the turntable steadily. Bottom of turntable is not hot as air extracted upwards from receiver vents is immediately being forced forward by rear fans and forced out of the front of the cabinet. These fans are GREATTT! I can feel the hot air being pushed out the front when I stand in front of the cabinet. Feels like a furnace is on. Really glad I found these on Amazon because this is really a great receiver and was concerned that it would sizzle out on me. Now I have to figure out how to hide the wiring on the floor. Pictures enclosed for viewing fan setup and turntable elevation. Wishing you all the best.
