Well, I have the coolermaster elite 130 tower and it's mini-itx, and the cpu fan is just underneath the PSU, so I flipped the PSU to act as an exhaust fan, Also, there was a 80mm fan on the side but I managed to put a 120mm (120x120x25) on it, it's a bit strained but it helps alot more than the 80mm fan, but the thing is, most of the hot air goes to the PSU becuase it's just ontop of the CPU, and it's kind of hot If I put my hand on the back, so, if I flip the psu, the 120mm fan that it's like 2cm away from the cpu will take out the hot air, but that would mean that the bottom side of the psu, the one that has no fan, may get really really hot, but at least the PSU will get fresh air, usually my CPU runs at 60 ºC, and I probably will buy a liquid cooler, but for the mean time, what do you think

Is it better to have those 60 ºc going mostly into the PSU that has no fans to take air out, just the one that takes air in (s12 620w seasonic psu) and the rest through the 120mm fan, or flip the PSU and let it's bottom part heat a bit so the hot air goes to the 120mm fan and out of the case? (the gpu fans can also help pushing some air from the cpu to the 120mm fan)

Yes, it won't get THAT hot, you'll be fine. And the PSU fan bringing in cool air will counteract it.

So you say it's better to let the metal to heat up a bit instead of having hot air going into the psu? becuase it might get hot and I won't be able to notice, and the heat will go past it and maybe get some of the lower parts of the things inside the psu heat up
