Over two years ago I mounted a fan on an Adaptec 5805 as they are getting quite hot in desktop systems. Trouble is, I forgot what cooler I have used - all I remember is that it took me a long time to find that one so I am hoping someone here has an idea.
There are a few water cooling solutions out there which fit well, this one needs an active fan though.
This is the baby in question
The holes are 45mm apart
Big question, does anyone know of a fan with mounting holes 45mm apart and in the middle

LONG shot - I know .. but gotta try ey
