Just upgraded from a 160w junk PSU to a 350w Imix Atx power supply. My other PSU had a distinct fan on the bottom of it and some vents on the outlit side. This one seems to only have a vent/fan looking thing on the outlit side. Is this bad? do i need to grab another fan for my comp or should i be all set? I was actually thinking about just leaving my case cracked open if i needed a new fan (of course i would shut the case when i turn it off). i don't wanna overheat or burn something out :0
