Lian-li PC7USB Case Fans

[spluff]

What kinds of fan is in Lian-li PC7USB - this is case is around 5 year old now....... but it still looks cool..... it has 2 front fans and 1 rear....

I have 7volted them but they do sound a bit loud still and i wonder

a. what size fans they are?

b. what size fan can i replace it with (does it have to be like for like size wise?)

c. recommended fan that i can use
Cheers

thanks yewen - did you find out the size?

i dont really fancy modding the case - seems to hard

would getting another 80mm fan sound quieter and be more efficient?
i couldnt find sticky on fans in this section - does it exist in another section?

what 80mm fan would you recommend me if i bought from ocuk today? something quiet but with decent airflow........
