Low profile ESC fan ?

[vrooom]

I am looking for a really low profile ESC fan.. say 5mm tall? if there a such thing?

It is for hobbywing xerun 60sd esc. it has already got 10mm tall fan but its too tall on my 22.

Does the such thing exist?

Lrp ones are approx 6 - 7mm tall

6-7mm are about as small as you will get.
There are a couple that do them
