These are 120x38mm fans and are very quiet when undervolted like this. They have a better airflow vs noise ratio than even the Nexus fans and do better against backpressure. They do have some vibration to them so it's best to mount them with vibration isolators. They are heavy metal frame fans, but only cost about $9 from http://www.alliedelec.com/Catalog/pf.asp?FN=551.pdf |
How have these worked for you in the long term?
Any overheating or other issues at 120v?
