I was digging thru my vast collection of dumpster dived electronic and computer parts when I came accross 2 types of 5 VDC fans.
(1) Is a subminiature "Pancake Fan" it's slightly less than an inch square and about .40" thick...
Made by Densitron corp. PN# OPF25A05E DC 5V .2A
It came out of a Notebook docking port was a power supply cooler....Fan is very clean looks unused.
(2) Looks exactly like the type of fan that came on some types of the old 486 Gold anodized heatsink CPU cooler.
It's made by Shicon engineering co. LTD and called ICFAN PN# 0410N-5V
This was salvaged from a External SCSI CD-Rom drive enclosure and also was a power supply cooler.
Both have leads attached with a 2 pin female socket just like the Tennmax only the Densitron is 3" long and the Shicon is same length as Tennmax.
Just thought I would share this info in case others have older parts laying aroung collecting dust or just want to see if there local electronic supply has these.
(some time back somebody posted they got a good deal on a quantity of submini fans...
Hmmm Q16 coolers.....)
