Coolerguys Dual 80mm USB Cooling Fans

Great for managing home theater center’s heat
I’ve been using these fans for years in my home theater setup. I bought them when I noticed my Xbox was generating enough heat that the top of my entertainment center was extremely warm from the Xbox, which was in the first cubby directly below it. I bought these and initially just set them up standing on either side of the Xbox, one pulling air in and the other pushing it out, creating a circulatory airflow. It worked great, and after a few weeks, I was satisfied enough with their performance that I cut out a couple of holes in the back of the entertainment center and mounted them to the back. You could definitely feel the heat in the air these were pushing out, but the temperature difference around my Xbox was a major improvement. Plus, these things are super quiet! If you were in the room with no ambient noise and you really focused on them, you might be able to hear them… maybe. Even right next to them, they’re practically running at a whisper as far as noise level goes.We eventually got a new entertainment center cabinet, and I relocated my Xbox to my man cave, but the new cabinet was fully enclosed, and I was sure that the lack of air circulation would not work for our receiver, so once again, I got my hole saw out and cut a couple of holes in the back of the cabinet, directly behind the receiver. For power, I just borrowed one of the eleventy-billion USB power cubes that seems to be multiplying around the house and let them run 24/7. I suppose I could use a thermostatically controlled power supply or something, but I haven’t gotten around to it.Now here’s the kicker and the reason why I would buy these again without a second thought: I’ve been using these fans for probably 8 years now. Remember how I said I didn’t have them thermostatically controlled? They’ve been going practically all day every day over that time. No noise, no slowing down, no problems at all, and all for less than $15. If they up and died on me tomorrow, I’d be on Amazon ordering up the exact same fans to replace them, I’m that happy with them. Outstanding value and performance like this is hard to beat.

Better than expected. Solved problem immediately.
Exactly what I needed. I bought a new wood entertainment center with slots for dvd, amp, ps4 etc… that are pretty normal in size. I noticed about a couple of hours in while playing my PS4 that it was running all the fans, even the auxilliary fans in high mode. The noise was not normal since I’ve had my PS4 for over a year and never heard them kick on like that before. I could tell the unit was hot to the touch as well so it obviously was not getting the proper ventilation it required now that it was in this new cabinet. The fans are perfect for this and solved the problem immediately. I placed one fan on each side of the slot in the entertainment center where the PS4 sits. I used one as and intake and the other as an exhaust to circulate fresh cool air in and push it out the other side. No more extra heat. No more fans running on high. Also these things are virtually dead silent unless you have your head right up to them. Very simple, cheap, and effective. No additional power supply required, no funky wiring, just plug it into the PS4 USB port and tuck the wires aside. love it!

Honnêtement, je m’attendais à des performances de bas niveau. Mais je préférai prendre ces modèles, car pas chère, et que je ne voulais pas charcuter d’autres ventilateurs, prise, transformateur…Au final les performances sont bonnes et les ventilateurs silencieux (comprendre ici, que j’aurai eu aussi bien pour plus chère avec des Noiseblocker). J’en reprendrai sans hésiter si j’en avais besoin.

montate su un modem router tim, funzionano bene e sono silenzioze e spostano una buona quantità di aria quindi per il momento fanno bene il loro lavoro speriamo che la durata sia altrettanto buona spedizione e imballo tutto ok
