Motherboard heating up too high?

I checked my mobo temps and it was reading at 45Celcius. I believe that it's too high for any system? I'm using a A7V. I was playing Serious Sam and the computer hang. I rebooted and while booting into windows, there was a continuos beep and my pc went into standby mode till I move something. Could it be the mobo overheating? Where's the thermistor for the mobo anyway?

45C is pretty high for a mobo temp, but I think it should still be within safe operating temps. What kind of case are you using? If it's a mini or mid tower then you may need to do a little work to get the temp down. The only thing I can suggest is that you make sure you have all wires and cable tucked away so they aren't hindering airflow. Also, invest in some good case fans if you haven't already. Are you using Motherboard Monitor 5 for your temp readings? I suggest you use that program since it seems to be the most accurate. If you still can't get your temps down then you may want to try modding your case. I did and my temps dropped significantly.

What case fans are good? I'm thinking of putting two 80mm below the PSU. One taking in air the other channeling air out. I've tied all the wires together now and the temp dropped up till 10 Celcius. I'm using a mid tower case anyway. Using sisoft2001 to read my temps. :)

Hi there,

If MikeWarrior2 sees this thread, he'll give you the exact "thermistor-related reasoning explanation"...he's awesome. I'm not awesome, but I CAN tell you that Asus boards typically read higher than other boards. It's a well-known fact that others on this board will corroborate. Somewhere around 5C, I believe.

However, even 40C is way too hot for a case temperature. You have no airflow thru your case. That's your problem. Which case RU using?

What you need is a steady flow of air from the front, bottom of the case to the rear, top of the case. If you put two fans on the rear panel, under the PS, make sure they are both blowing out, not one in one out. That would get you essentially nothing. A much, much better solution is one fan on the front panel sucking air in and one fan on the rear panel blowing out. That will cool your case fairly well. Try it. Good luck.

EDIT
I just noticed that you said "using Sisoft to check temps." Do you mean SANDRA? SANDRA is notorious for bad temperature readings! Use either Motherboardmonitor 5 (MBM5) or the VIA Hardware monitoring utility that came with your mobo!

MichaelD is absolutely right about the fan placement. As for fans, I bought some Sunons from millisec.com. They're a good company to deal with and have pretty fair prices. Sunon offers many different speed fans, so just get the ones that suit you. I got the fastest ones because I wanted my case to be nice and chilly at the expense of a little more noise. Some people swear by the Panaflo fans, but I found them to be a little expensive for me. I suggest you go with the 4 pin fans that connect directly to the PS rather than the 3 pin ones that connect to the motherboard because some motherboards can't put out enough voltage to drive the fan correctly and you could end up frying a header.

If you put two in the back, one sucking and the other blow, all you have is air going in and out, cooling nothing.

Actually Michael, I have found Sisoft Sandra to be pinpoint accurate when reading the temps from my A7V133 BIOS. I have rebooted a few times to check and make sure it was returning an accurate temp. I like using Sandra for this so I don't have to keep a program always running in the background...I can just check it fairly easily when I feel so inclined.
