DigiTimes reports ultrabooks are boosting demand for 4mm fans, the smallest micro fans that current technology can produce. These fans were originally designed for handsets, but were found unsuitable for this application due to noise issues when making calls.
The sources pointed out that 4mm is the thinnest size that current technology can produce a fan, and the micro fan was originally meant to push into the handset market; however, because the fan's noise is not suitable for handset products, which users place near their ears, the micro fan is being pushed in the ultrabook market.

Currently, most existing ultrabooks either adopt 5.5mm or 7mm fans, with Acer's S5 ultrabook being the only model known to have adopted 4mm micro fans. As for pricing, a standard fan is usually priced between US$1.15-1.20, while micro fans can be priced at more than US$1.60-1.70.
