hey guys,
My Cabinet does not have an air-went on it's top side( only on back side)...its an hp pavilion p6140in. My old PSU used to get fixed in the upper corner of the cabinet but had a vertically mounted fan( unlike Corsair's Horizontally placed fan).my old psu is this-a bestec 250 12z and my new one is a corsair vs 450...ive checked their dimensions and they are the exact same but the fan on the new one will have no outlet...will i have to keep the side of my cabinet open? or is the technology made to dissipate heat either way?
