Ralph asked: Hello guys, i am using this board with an FX 8320 and a Seidon 120V AiO pushing out air in the rear side of the Case. My problem is the thermal throttling at 65 degrees, how can i disable it or volting right to make it work at least stock and safe? When i disable everything in BIOS in the CPU Configuration (eg. Power Now, C1pe states, Acpi...) it still throttles. Can you help me? May 14,2014
Andrew H: It's your NB. I'm having the same problem and I've found the solution. Now realize I've replaced the TIM on the NB HS and added a fan. It didn't really improve the temps by much. It would reach 65c regardless it just took a bit longer. It just isn't enough cooling. Regardless. If you go to Hardware Health Configuration and change PWM Processor Hot from Auto to Disabled it will stop it from throttling down at 65c. My NB will now get to about 75c and settle there. I know this is hot. Poking around the internet seems to reveal that critical temperature is 80-90c. (one place said up to 105c) Jun 03,2014
Ralph: 75 degrees with no nb cooling and prime95 - stable under load? Jun 04,2014
Andrew H: Ok looking into it more today it seems it's the mofsets. (VRMs as you said) I'm using OCCT large dataset which is basically the same thing with better monitoring. I forgot I put some small memory chip heatsinks on the VRMs and that may have slowed the heating. Yeah it's completely stable and doesn't throttle. I'm prob going to add some bigger heatsinks to the VRMs. (later) Jun 04,2014
Ralph: If i turn off PWM Processor Hot, can't it fry my motherboard and components? I'm just afraid of burning my components in case water cooling might fail or the summer temperatures affect too much. I will try your suggestion and report back with my temps under prime95. Also i let turbo enabled, trying to run it out of the box. Jun 09,2014
Andrew H: I know they say no links but this may help. (this is totally non commercial) [

] None of the HS on the VRM and PWN chip had little effect on the temps. Thus where I surmise where the sensor is. If I turn the fan pointing towards the NB all the way up, it will climb to about 62c. If I turn it off or down too low or off it will climb to or past 80c. (I don't let it go past that. If I keep it at a quiet but effective medium it will go to 70-75c. I think the additional cooling dropped the cooling by about 4c. BTW I'm running in a 26c room with a very small case with crappy ventilation. Do a search for [Everything You Need to Know About The Motherboard Voltage Regulator Circuit] and you'll find a article that explains all this. As far as I know this does not effect the shutdown temp so loss of cooling could still be mitigated. This does allow for the voltage system to work at a level such that the processor can run at full speed. Jun 10,2014
Ralph: Okay, i disabled it, reaching 80 degrees playing metro last light, 30 minutes of prime get it to about 90 degrees...it seems it settles at about 77 degrees at gaming...is this okay or even risky? i also have to say that it´s summer. Jun 11,2014
Andrew H: Your best bet is to put a small fan or some sort of air blowing on the north bridge half way to the audio headers. This seems to mitigate most of the heat and at least in my case keeps it around 70c under heavy load. I would not let it go far past 80c as the sensor in this area is near the audio chip. 77c in my opinion is acceptable, 90c would have me shutting down. Remember the VRMs can handle 100c, but the components near them can't. (audio and NB) Recapping my temps with small fan not enough to really hear.
