ps3 ultra slim over heating?

Has anyone got a new ps3 ultra slim wanting to know if they have any heat issues with long extended hours of use? I have googled and not gotten anything from it so turning to the forums here to hopefully get some answers. Pleas if anyone has any info it would be of great help such as if you have one how many hours its used daily and or the area its in. Looking to get one just unsure atm. Plan on keeping it alone on second teir of my tv stand with over 2 feet of space in all directions and it would be sitting flat not a fan of standing it up.

as long as it has at least 30cm clearance around it in all directions, ur safe. the new slim is the lowest energy consuming model thus far.

I have the 500 gb model of the new ultra slim and no problems what so ever.

what kind of hours do you put in on it and area is it in open kinda closed in etc

thats what i am hoping for just wished sony would have put more vents on it than the back and the bottom of it any idea wich vents take in air and wich ones push out air i was thinking vents on back is in ones on bottom is out but not 100% on that.
