tmpfs, to clean every x min files older than x min

Im just doing some tests.
To setup a cron job to purge outdated cache files that are more than 8 minutes old every 10 minutes on disk its an easy task.
*/10 * * * * root find /tmp/diskcache -type f -mmin +8 -delete 2>/dev/null
I want to move diskcache to tmpfs. My idea with tmpfs (otherwise tmpfs eat half ram of default) is:
/etc/fstab
tmpfs /dev/diskcache tmpfs nodev,nosuid,size=2G 0 0
The new cron will be (correct?) but, most important, is it the best approach ?
*/10 * * * * root find /dev/diskcache -type f -mmin +8 -delete 2>/dev null
Thanks

Probably depends what is cached there. Pruning every 10 minutes files older than 8 min makes lifetime of the cached something between 10 and 18 minutes which seems quite a range, but rather short at all...
Also keep in mind that the linux filecache usually works very well and there shouldn't really be a need to try and circumvent or replace it.
Its a test about private cache (OpenLitespeed, Cache Module) so i dont need to cache object for a long time because everything is cached for a single person.
Not /dev/ ! 
(http://www.tldp.org/LDP/sag/html/dev-fs.html) but maybe /tmp/diskcache 
My goal was to try to find out (and correctly ofc) if this is a good approach to lower server load after the classic "tricks".
Anyway i wrote something .... meeeh...
Lol
