cooling fan?

[forest1]

hi can anybody point me in the right direction, I am looking for a cooling fan for the tm800hd I brought one recently and works fine but I can hear it spinning, I want a silent one like the one it originally came with, unfortunately I have lost it, help please

I have found the cooling fans in TM5402HD's particularly irritating, so I experimented. The old Pace3100 Sly+ boxes had quiet fans, but being 12V, wouldn't start up on the 5V fan supply in the 5402. So I bought a couple from China off the 'well-known auction site' and... OK the motor IS silent, but it seems to be quite efficient & blows quite hard, so I can actually hear the air flowing- but not nearly as annoying as the original effort- and at less than £3.....

But check the fan voltage on the 800 first!!
