So I just built this PC like one maybe two months ago and I was wondering if I did right matching the M5A78L-M/USB3 with the FX 6350 and the R9 270x.I searched a lot and they told me that the 760g chipset was enough for the FX 6350 if I am not overclocking.To be honest I am not really that much into overclocking,I don't like it at all,so I said that it's cool.

Now my problem is that I tried using different programs for monitoring the temperature and the one that I trust the most is the one that the motherboard came with.It says that my motherboard is going like 60 degrees celsius under 2-3 hours of heavy gaming.I have only one fan that works as intake at the moment and to be honest here in Greece it's really hot in these summer days.

My question is,is it save to keep this system running? I don't want to risk burning my CPU or GPU just because of this motherboard,I thought about changing it selling it along witht he FX 6350 on the summer and get a Asus-M5A99X-EVO-R2-0 with a FX 8350, but if it's safe to keep my system running the same I will not do this and wait 2-3 years for something better.I want your opinions on what I should do,thank you very much.

While 60C is a bit high for a motherboard, i don't think it would do any damage to your components as long as you keep it below that, and monitor your GPU and CPU temps are not getting extremely high. You do need to get a couple more fans in there. One intake will just blow the air in, but then you will have hot air sitting around. You should have at least one outlet fan. You can get fans online for less the n $15, and one more intake fan, and one outlet fan should cool your system down considerably.
 
Yes, the M5A78L-M/USB3 is good for the fx6300 in the most situation, but you need consider the room temp, and the case cooling, etc. too. The 60C is the high side for the MB.
If you have only one fan, I recommend to try to use it for exhaust fan, because if you use it for intake, that means your PC cooling is the positive pressure configuration, which is the average cooling performance. Also you want to make sure the cool air will be intake from lower/front part of case, and exhaust in the upper/rear case. Like http://www.extremetech.com/wp-content/uploads/2012/05/Air-flow.png

Someone test the cooling performance by placing the fan in different positions, from what I read if you have one fan then put it in the rear of case for exhaust fan, here is info: http://icrontic.com/images/draco/articles/pc_airflow_heat_cooling_guide/systemtemp.gif

If you still have problem then try to open the side panel and use one fan to blow the air into the case. Or get the aftermarket cpu cooler (at least 110mm or 120mm fan/heatsink) like in the link http://www.legitreviews.com/images/reviews/1927/cnps_8900_extreme-025.jpg

Thank you guys,I will just buy two 120mm fans one for the side of the case and one for the back of the case, but could you answer one more question? You think it's worth changing motherboard at the moment or should I just keep it as it is.The PC is working without problem,it never shut down cause of big temps and I can tell you I closed like 6-7 hours of non stop Battlefield 4 and DayZ.
