Fan for volcano7+

I was wondering what is the best fan to switch with. THe one that comes with is too loud. I want something quieter but will still give me ok good cooling. I was also wondering if i can use a one of those fan adapters.

Well, not being familiar with the Volcano series coolers, I can't say if a fan adapter will work. If the fan is screwed onto the heatsink then yes, a fan adapter will work. But if it uses clips to hold the fan down, a fan adapter won't work. As for a good quite fan, I would reccomend a Vantec Stealth, or a Sunon. I am a little partial to the Sunon fans though.
