Antec Three Hundred Two - Side fans?

[winstainforth]

Will be building my new system this weekend using above case.

I've got a Cooler Master Hyper 212 Evo to add to my Asus P8Z77-V PRO and i7 3770k. Graphics card is the MSI Geforce 650 TI. Pu is an XFX Pro650W xxx edition.

I bought two 120mm akasa vipers for front intake.

My question is regarding the optional 2 side fans, are they worth adding, what benefits would they bring if any?

I forgot to add, I'm so excited about upgrading from my 6 year old core 2 E6600.

I added a side fan on my antec 1200, made no difference whatsoever.

iirc on my old nzxt hades with a 200mm side fan, it dropped my gpu temps by 1.C, so its not worth the expense imo
