Is one rear fan enough for a basic build?

[Avenger17]

I'm making a cheap rig with a pentium 6850, hd 6770, h61m/u3s3 mobo, 8gig ram. Is one rear fan enough, or would I need to bump the case up to the HAF 912 for two fans?

NZXT one fan: http://www.newegg.com/Product/Product.aspx?Item=N82E16811146061&Tpk=NZXT%20GAMMA%20Classic%20Series%20GAMA-001BK%20Black%20Steel%20A

Thanks guys

I assume thats a Pentium G850, not 6850

you should be fine with one rear fan, but both of those cases are overkill.

get the Rosewill R102

Yeah I meant the G650 lol. So I would never have to install another fan or have any other source of cooling?

No, the SandyBridge CPUs run nice and cool, especially the Pentium/Celerons. Neither of my SandyBridge PCs have any fans other than the CPU HSF and they don't get too hot.
