top mounted PSU getting a little bit warm

[Guest]

So, my PSU is top mounted with the fan drawing air from inside the case. It's a micro tower mATX case and I have a top-down cooler for my CPU, which is below the power supply. Now, most air goes out my fast rear exhaust fan, including pretty much all of that from the graphics card, but I think some of the CPU air may be being vented out the power supply.

Now, I have a system that only (calculated) draws maximum of 290 watts under full load, and my power supply is a Cooler Master V550S 80+ gold, so obviously I have WAY too much headroom there. When I'm playing a game prone to upping my temps (battlefield 4 isn't one, yet battlefront 3 is) I can notice that the PSU back is kinda... warm but not a lot, and there isn't much air coming out because the PSU fan isn't bothering to spin up properly which is probs to do with the fact that it is 550w. It's definitely warmer than it is when idle, but not by a lot. When playing battlefield 4, the power supply sits at ambient temp. Is it something to worry about? I don't have enough money to buy a better case with bottom mounted PSU, and it's probably nothing, but I want to hear from someone who knows.

It's nothing to be concerned about.

You're right, some of the warm air inside your case will be vented through the PSU. This is because PSU fans act as intakes rather than exhausts. Also remember that hot air rises.

You could mitigate the issue (although it really isn't one) by purchasing a tower CPU cooler, such as a 212 EVO. This will push the warm air generated by the CPU toward the exhaust fan at the rear of your case.
