Pour faire avancer un peu le schmilblick, voir aussi la technologie de guidage utilisée sur le ventilateur (palier , roulement,etc.). Cela a des conséquences sur le bruit, la durée de vie du système. Sachant aussi qu'un guidage de piètre qualité sera peu sonore au début, mais pourra le devenir rapidement avec l'usure...
EDIT : éviter les ventilos à base de sleeve bearings bon marché et peu fiables dans le temps
Sur ma "Flex", c'est un double roulement (ball bearings). Sur la coolmaster U3, ça a l'air d'être du Rifle bearings ce qui expliquerait le faible bruit => https://www.coolermaster.nl/shop/product_info.php?products_id=754The type of bearing used in a fan can affect its performance and noise output. Most computer fans use one of the following bearing types:
* Sleeve bearings use two surfaces lubricated with oil or grease as a friction contact. Sleeve bearings are less durable as the contact surfaces can become rough and/or the lubricant dry up, eventually leading to failure. Sleeve bearings may be more likely to fail at higher temperatures, and may perform poorly when mounted in any orientation other than vertical. The lifespan of a sleeve bearing fan may be around 40,000 hours at 50 °C. Fans that use sleeve bearings are generally cheaper than fans that use ball bearings, and are quieter at lower speeds early in their life, but can grow noisier as they age.[3]
* Rifle bearings are similar to sleeve bearings, but are quieter and have almost as much lifespan as ball bearings. The bearing has a spiral groove in it that pumps fluid from a reservoir. This allows them to be safely mounted horizontally (unlike sleeve bearings), since the fluid being pumped lubricates the top of the shaft.[4] The pumping also ensures sufficient lubricant on the shaft, reducing noise, and increasing lifespan.
* Ball bearings: Though generally more expensive, ball bearing fans do not suffer the same orientation limitations as sleeve bearing fans, are more durable especially at higher temperatures, and are quieter than sleeve bearing fans at higher rotation speeds. The lifespan of a ball bearing fan may be around 63,000 hours at 50 °C.[3]
* Fluid bearings have the advantages of near-silent operation and high life expectancy (comparable to ball bearings). However, fans using fluid bearings tend to be the most expensive. The enter bearing fan is a variation of the fluid bearing fan, developed by EverFlow Technology Corporation.[5]
* Magnetic bearings or maglev bearings, in which the fan is repelled from the bearing by magnetism.

) donc je cherche une tablette assez grande mais je ne trouve rien !
