Seasonic M12 700w supposed to be blowing out warm air?

What's your rig?
Does the speed of your PSU fans run at a constant speed or throttle up or down?
Just trying to understand your concern better. My Seasonic S-12 seems a mild warm which is more than I would normally expect.
I have excellent airflow so my case interior is about 29C. I use a IR temp probe to take random spot checks.
I assume that the exhaust air is warm to the touch. Maybe the source of the warm air is coming off your mobo/CPU/GPU, or maybe not?
You can best answer that. We await your investigation.

The warm out is defiantly a mixture from the components in the PC(CPU mostly) and the PSU getting a workout. But when any power supply its being used its gonna get warm which is where most of the warm air is likely coming from. Don't expect any PSU to blow out cool air after the system has been turned on for a little while(even if its idling).
If your getting warm air and it idling try gaming for a little while and with the game running try checking to see how warm the air is.

Was the PSU the only change or did you add a bunch of heat-generating components like a faster CPU and video card?
Also, if the PSU runs the fan slower it will push less air, so I'd expect that smaller amount of air to be warmer. Same amount of heat + lower airflow = warmer air.

Dittos Dave. I think lots of PSU makers run their fans too slow on purpose in favor of low noise over optimum performance of PSU so I've taken to manually controlling them.

Seasonic PSUs are made to be quiet, they can't do that with a fan spinning very quickly, so the air in result may be warm.
The seasonic S12, M12 suck air thru the inside of the case and blow out air out the back in turn if your componets are hot or the air than warm/hot air would be coming out the back.

My M12 700W has a big fan on the bottom - it quietly draws air out of the case, and it "drifts out" out the back. There is nno rear fan. There is, however, an auxiliary fan in front which is thrmostatically controlled. It only turns on to push air out the back if it senses a high enough temperature within the PSU. Mine has never turned on, so silence is golden.
The S12 and M12 are some of if not most efficient PSUs available, that means less heat per watt of output power hence the fan can run slower. Also Seaonic has one of the best active fan controllers in any PSU; if the load is low so is the heat; no need to spin the fan faster and make more noise then is necessary.
I'd say if you run even a Seasonic a bit cooler it will help both the longevity and the efficiency (lower resistance rises due to heating).
