maklabouhlel Posted November 5, 2010 Share Posted November 5, 2010 I bought the obsidian and realize that the psu can be installed in one direction only. I would have liked the psu fan to face the motherboard and not the floor. Was there a reason for this? I see the other Corsair case does not have this problem.

FlawlessSoul Posted November 6, 2010 Share Posted November 6, 2010 It is due to the compartment design for airflow - air for the PSU is pulled in the bottom and then straight out the back. For what reason do you want your PSU to be the other way up? Link to comment Share on other sites More sharing options...
maklabouhlel Posted November 6, 2010 Author Share Posted November 6, 2010 Cause the pc is going to be on a carpet and I don't want it to suck up. Also I do not believe the space under the pc is adequate for airflow. Link to comment Share on other sites More sharing options...
FlawlessSoul Posted November 6, 2010 Share Posted November 6, 2010 I have mine sitting on carpet - it's not a shag rug, but the filter at the bottom is fine and it gets enough airflow. Link to comment Share on other sites More sharing options...
McShack1 Posted November 6, 2010 Share Posted November 6, 2010 My 700D is sitting on a 6" high stand that I built to keep it off the floor a little, but you could make it higher. The top of the stand can be a simple 10" wide board or something with vents to let air in if you like. :idea: I have also added a Scythe Kama Bay Plus SCKB-2000BK 5.25" bay front intake fan to draw cool air and blow across the RAM memory portion of the mobo before being sucked out through my top exhaust case fan. :D: Link to comment Share on other sites More sharing options...

gweasner Posted January 14, 2011 Share Posted January 14, 2011 I have the same question and I'm wondering if someone from Corsair will sound off: What way to put PSU in case. I don't know if I should put the PSU with the fan facing down, or the fan facing up? My LianLi caes is a bottom mount PSU case, so if the fan is up it would face the motherboard. I suppose it would pull air hot/cool off the GPU and the CPU. My case has a vent at the bottom, and there is about 1/2 inch space under the case on the outside between the feet and the floor, and 1/4 inch from the PSU mount rack to the vent on the inside of the case.

Wired Posted January 14, 2011 Share Posted January 14, 2011 Either way is fine. Link to comment Share on other sites More sharing options...
denydog Posted January 15, 2011 Share Posted January 15, 2011 I sometimes get the impression that there is a misconception among some, regarding how much space is required under a case's bottom intake. The way I see it, every case I can think of with a bottom PSU intake grill probably has sufficient clearance provided by the case feet. I know with the 600T, the clearance from the intake filter to the desk surface is about 5/16 in., which seems like it might be restrictive, but the air is drawn in from all sides, 360 degrees, so maybe there is more area for airflow than it might seem. Unlike an exhausting fan which has a tendency to expel air in one direction for a much larger distance with greater velocity, an intake draws air equally from all possible directions with lower average velocity. I think of it as air just filling in the negative pressure created directly in front of the intake. The differences between intake flow and exhaust flow is also why I don't think a PSU intake facing the GPU or MB will draw much heat away from these specific components, unless they are located very close, say an inch or two. Though it would function like any other case exhaust fans to help draw air out of the case. If I intended to place a case on a carpet, I'd definitely have a hard surface, like a board with the same dimensions as the case bottom, on top of the carpet.

gweasner Posted January 19, 2011 Share Posted January 19, 2011 As I think about this if airflow isn't an issue with the fan facing the vent, I can see an issue with the fan at the bottom of the case facing up. If for some reason something falls in the fan and makes it past it could damage the fan, as well as the rest of the PSU. I'm going to try mounting it with the fan facing down at the vent. On the link under installing the PSU the fan shows facing the ground, however the PSU for that case is top mounted not bottome mounted, hense nothing will fall into the fan.
