I installed one above and one below my gpu and my gpu is very quiet now. No more racing fan noise.Easy install. Worked as expected in an HP desktop PC.This is amazing, my temp gpu dropped from 56C to 36C. And now after overclocking while running games, my temp can be under 83C. It's a life changer!Haven't been able to test it yet but was easy enough to install. Waiting on power adapter to complete test but I will update if anything of interest comes up.This thing blows air out pretty well. A real good assist to my overworked gtx 1080.I like computer HW made by Star Tech. They are all high quality.These definitely keep things cool, but they are LOUD. Had three of them and it sounded like there was a vacuum on in my room. If noise is not an issue for you, then they work great.fixing my old pc from early 2010, and it's a decent 32 bit system that works wonders with old games that don't run very well on 64 bit pc's, but overtime it needs some maintenance, one of my biggest issues was obviously cleaning and restoring the motherboard, graphics card, cpu, heatsink and fans. the fans are the generic ones that do the job, but airflow is kinda weak by comparison to the more powerful ones, i don't really need them because it's an old pc, kinda expensive and not really necessary. When i finished cleaning/fixing my pc I did some testing to check if there’s any issues and thankfully it works perfectly fine but the air flow especially around the bottom of the graphics card is very weak, so people have recommend this Exhaust Cooling Fan to me. for 8$ its a steal, very easy to set up, the only thing you need is a nail that fits into the metal fan case. works perfectly and now the pc finally has proper cooling that prevents overheating.Cada vez que el ventilador arranca, se detiene, o cambia de velocidad - hace unos silbidos bastante molestos y muy perceptibles. En mi caso se estaba usando como ventilador de CPU conectado a la Placa Madre que lo controlaba a través del conector 3-pin subiendo y bajándole el voltaje dependiendo de la temperatura del CPU. Debido a que de este modo, la velocidad del producto variaba constantemente (a veces la PM lo paraba por completo), se percibían este tipo de silbidos bastante desagradables.El producto es mejor usarlo a velocidad FIJA (tanto en el papel de ventilador de CPU como del gabinete) y a menos de la mitad de su potencia, ya que al máximo (12V) es muy ruidoso, pero a 5V del Molex (para mí) también es perceptible, y a 3.3V del SATA ya no arranca (ya que su voltaje inicial es de aprox. 3,5V).Por lo que como solución tuve que instalarlo en el gabinete conectado a la línea de 5V con una resistencia de 2W y 35 Ohm (RJ), que finalmente suministro al ventilador unos 3,5V y aseguró su funcionamiento silencioso y más o menos eficaz a velocidad fija.Este articulo es un extractor de aire (saca el aire del gabinete), cumple su función muy bien, pero el nombre del mismo te puede confundir, yo pensaba que aventaba aire al interior del gabinete (como un abanico común) y por eso lo había comprado.Si lo ven en esa posición en mi gabinete es porque lo desarmé y lo adapte para que aviente aire a su interior y enfríe un poco mi tarjeta de vídeo que parece un horno y los abaniquitos comunes no le dan abasto (Ya no quise devolver el articulo)The sales pitch said 0dB which is impossible, so I had my suspicions. The fans are way too powerful and EXTREMELY noisy at 12V, but run with sufficient flow at 5V which can be achieved by inserting a 39 Ohm 2W resistor in BOTH lines to drop 7V. 5V is above the fan's starting threshold, so no need for a starter capacitor. Still very good airflow, but practically inaudible. The metal plate is rubbish! One of the locating slots in the mounting ledge is too short causing the ledge to foul with the PC case locating lug so the fans cannot be seated the whole way down! That slot needs to be filed out to another mm to clear the locating lug. Cheap Chinese garbage! Once these VERY SERIOUS issues are sorted the fans work fine, BUT WHY SHOULD THE BUY NEED TO GO THROUGH THE HASSLE? GET SOME ENGINEERS! HOPELESS!Bajo 4-5 grados Celsius la temperatura de la tarjeta grafica, en m caso esta se ajusto perfectamente debajo de esta, basicamente ayuda a recircular el aire de adentro del gabinete hacia afyera de este mismo. Es importante que se use asi como se indica, de esta manera evitas que entre polvo dentro del gabinte.A fan is supposed to draw air in or pull air out depending on the blade shape, rotation, and which side you install it. This one has a manufacturer defect in that the blade touches the plate it is attached to, resulting in a fan that does not spin. I had to give it a slight offset in order for it to keep spinning. I'm still within the return window but it's too much hassle to go through the RMA process so instead will avoid StarTech next time.
