GA-970A-UD3P r2.0 NB Running too Hot for Comfort

Howdy again everybody! My parts finally came in and after spending a day hammering and bending on my PC case to house the radiator in the top, I've finally got everything installed and running!
I've only run into a couple of issues for the time being, and once again my google-fu has failed me on finding a solid answer. BIOS all running the default auto settings for the time being, I'll hit a rare occasion of graphics driver failing on me when windows loads, but my biggest issue is that I think my NB is running a little too hot for comfort.

I've updated my sig with my current rig setup if you need any information, but I'll throw a few pictures out here so you can see what I'm looking at.


There's the final product, minus the LED lighting.


I took that reading down into the fins immediately after taking my side cover with fan off. Highest temp I got was 62c after I let it run under moderate load for 15 minutes with the side fan not blowing on it, but that still seems a bit high for no overclocks.

Now I've googled for the past hour and the only threads I've come across are hot NB for the MSI 970 chipset boards, nothing on Gigabyte.
Is the NB suppose to run that hot? I've considered adding a fan or two, or just reworking my airflow in the case to hopefully bring that temp down a little.

Thanks to some amazing MS Paint skills, I've mapped out what I believe to be my current airflow.

Side fan blows directly into the graphics card, and a little overlap on the top is the little bit cooling the NB.
Brown is just a dead air zone, nothing that requires cooling in there.

What would be the best course of action to take a little heat off that NB?
I've also been thinking about putting a fan on the VRM so I can ease into some overclocking in the future.

I haven't touched anything in the bios aside from setting boot order. I remember reading something about the TMPIN2 being the chipset temp, but again answers from people are conflicting, so I'm going to assume HWMon isn't reading that correctly.

Well, a possible option would be to get an Antec Spot cool or something like that and position it so its blowing over the NB heatsink. I would take a slightly more direct path, get a 80 or 92mm fan, rest it directly on the back of the video card, and set it so that it blows directly onto the heatsink.

Yeah thats what I was thinking too, our whole one local shop doesn't carry any in stock, and I can't take waiting another two weeks for newegg to ship one out with them still being bombarded with the holiday shipping rush. I'm still searching around to figure out if this temp is safe or not, MSI claims that their boards are safe running at 60c and that it shouldn't become a worry until you reach into 70+ if that's anything to compare to.

Edit: Ambient temp is 20c and with the side panel on for the past hour I just took a reading and the NB temp was only 47, which seems a bit more reasonable.

Well, my other suggestion would be to ghetto-rig a partial duct from the side 120mm fan so a chunk of its exhaust is driven directly over the heatsink.

Well that has its own set of problems for me, I had planned on modding the case with a better window and I would have to remove the side fan as a result.
I started feeling around in the case to get an idea how the airflow is, and it just dawned on me that the graphics card is blocking off a good bit of flow up towards the north side of the board, do you think a 120mm fan in the top-front could handle the flow even with the side fan removed?

It certainly wouldnt hurt. Eliminating that dead spot should get some air moving along the back of the card, and thus along the NB heatsink.

54C should not be hot enough to cause instability or reliability issues, but if the temperature bothers you, attaching a 40mm fan to the chipset heatsink is a pretty easy fix.

Alright so I'm thinking I can slap a 40mm ontop of the NB to disperse the heat everywhere while the new front fan helps move it towards the rear exhaust, and then I can stick another 40mm on the VRM to push that heat to the top exhaust.


Does this look alright, or do I need to drink another cup of coffee or two before I think about air dynamics? lol

Total power consumption/heat production of that chip is in the single digit watt range. You don't need to fuss over the case cooling to cool it or account for any trivial disruption of air flow resulting from cooling it. A hamster blowing through a coffee straw could knock 10C off the part, and a silent 40mm fan moving about five cfm would probably knock get the part into the 30s C.

Though, now that you mention it, the whole system and especially the CPU and VRM would be cooler if you turned the radiator fans into intakes and opened up the I/O slots.
