Motherboard Temp: BIOSTAR TA970. Three temp readings(C). 20,28,45 under IDLE.Under load these temps are: 44, 29, 61. I'm worried about that 61.

CPU/GPU temps under idle: 17/30. Under load: 50/50.

The motherboard temperatures don't seem right to me. I checked the temps with Open Hardware Monitor AND CPUID hardware monitor and they show the same.

My mobo is brand new. Is there a heatsink that isn't seated properly? Here is a link to my mobo for further information. Thanks you in advance!

Well 61C is high for a motherboard, not dangerously so, but still high. What kind of fan setup do you have? How would you describe your airflow?

I would describe it as pretty good. I just bought a nice 70-120cfm Cougar fan.

I have that fan on the front pulling air in, one fan on the upper back pulling out, and another on the rear top pulling out. Furthermore, the temperature where I like is around 60-65 right now and I have my desktop sitting between two open windows to flow the cool air through it.

What does HWMonitor give as the titles of those temps? Are they named 'motherboard' or 'south/north bridge' or something like that? Or is it just TMPIN0/1/2?

Just TMPIN0/1/2.

Do any of the heatsinks on the motherboard feel hot to the touch when the PC is under load.

Just to be sure, there are 3 heatsinks on my board, right? The one in the middle, lower right, and top left (based on newegg overhead picture)?

Also I want to say thank you, I appreciate what you are doing!

No problem :) 

Yes, there are 3 heatsinks in the places you described.

I just put it under load, and while the temp readings were 41, 29, 61 I felt all the heatsinks. They all felt to be about the same warm temperature, bordering a hot feel (far from burning skin, but uncomfortable to the touch). Keeping in mind my case was wide open during the entire test.

Well that's a bit strange considering that the temps are so different and yet feel similar... I wouldn't be too worried about it. The reason for the temps is probably your CPU; A 125W 8-core really takes its toll on a board with 4+1 power phase design.

Alright, then I'll not worry about it! Thank you again, Eduello!

Hey.. sorry to bother you again. Based on the newegg reviews it would seem this is a pretty common problem. Do you think it would be a good idea to replace the thermal paste under the sinks?

Well it can't hurt the temps if you do it properly. Do you have experience changing heatsinks?

My preferred method is as follows:
1. Remove the heatsink.
2. Wipe off all the old paste.
3. Use Q-tips soaked in isopropyl alcohol to completely remove all of the remaining thermal paste.
4. Use the dot method for applying the paste (depends on the shape of the heatsink,). Here's an example with a CPU:

5. Attach the heatsink.
6. Check if there is any change in the temps.

Only for my CPU, not a motherboard heatsink. Are they much different?

When I was doing it I decided to research it a bit and saw that the cross method seems to get better coverage from videos like this one: https://www.youtube.com/watch?v=EyXLu1Ms-q4#t=133

Just thought you might find the video to be interesting.

Differences between motherboard and CPU heastinks shouldn't be that big; They're both just basically hunks of metal attached to something to keep that something cool.

The cross method is good too, but too much thermal paste is not a good thing either. The cross/line method might be better for the motherboard heatsinks since they allow you to control how the paste spreads.

Hello again! So I bought a infrared thermometer and removed the side panel of my case to get to the underside of the motherboard and tested the temperature of roughly underneat my CPU and THAT is where the 61C reading is coming from. So, since it's just under my CPU and my CPU temp reads normal, I'm fine right?
