Passive cooling 2 3870s

[Jatisogi]

My case is a P183 with 2 quiet Yate Loon intakes and 1 exhaust. the cabling is clean so there's no obstructions. Would it be okay to put Accelero S1's on my crossfired 3870s?

If it will fir on your case and doesn't mess with anything inside then why not? make sure it will fit and doesn't conflict with another hardware inside your case...
can u show us the link for this accelero S1?
