[SOLVED] How can I stop my CPU temp from fluctuating?

[mtyms818]

I recently got a CPU temperature app to monitor why my cpu could be underperforming, and it seems that the issue is when the temp hits around 50 degrees Celsius, the computer will automatically cut down on performance in order to drop it to around 27 degrees Celsius. The other problem, other than the fact that it kill performance for 5-10 seconds, is that my computer can keep the temperature stably at slightly below 50 degrees Celsius. Is there any way to turn this feature off? I'm pretty sure that doing so will have little to no affect. As of the lifespan of the CPU, I'm replacing it soon, but want to make sure it's not a lost cause and may consider giving it to a friend.

I have an AMD FX 9590, and a MSI 760gma-p34(fx) for a motherboard (i've heard it supposedly can't handle this CPU, but please disregard, as I'm pretty sure this is not the issue for my case).

I would look towards the motherboard. 50c is not going to cause any throttling to loose performance.
Is your cpu overclocked?
What are you doing whe. You see the performance drops?

Your VRMs are overloaded. That motherboard is a very poor choice for a 125w CPU and you are trying to run a 220w CPU. It's not going to work.

^ Agreed, probably your motherboard.

To confirm it's not your CPU overheating, please use AMD Overdrive to measure thermal margin under load. Higher thermal margin is better, if you get close to 0 then the CPU may start throttling. What cooler do you have?

I believe I have a corsair H60

I'm usually playing video games when this happens(Rainbow Six Siege, Overwatch, etc.) Also, my brain is too small for overclocking, so I never did it.

No, you are NOT sure. Because the board is 100% your problem. Even with a top tiered Crosshair, Extreme 9 or 990FXA-UD7 board, which are INTENDED to be used with that unholy voltage leaking processor, and very high end liquid cooling or a top tiered double finstack air cooler, people STILL have trouble with those processors. Your board, can not, and could never, handle that CPU. No. Way. Possible. Ever.

Your board is not intended to be used with anything higher than a 95w TDP processor, and that's pushing it. Your CPU is a 220w voltage eating monstrosity. It's amazing that it even WORKS on that board, but there is no possible way the thermals are in check or the voltage delivery is stable, not to mention no possible way your VRMs are not overheating. It could never happen on that chipset. There is NO board from that chipset that could handle that CPU.

Those poor vrms. The 9590 would want a decent motherboard like a 990fx asus.

Even that Sabertooth board would not handle that CPU well. I have that board and have seen what an overclocked FX-8350 can do to the VRMs even with superb cooling configurations. I know other people who have TRIED to run an FX-9590 on that board, and other boards. The only boards that CPU should even be attempted to be run on are the three I mentioned earlier, and even then, success is poor at best. Using water cooling even seems to make it worse, because then there is no residual airflow over the VRMs.

Only a mono-block configuration where the VRMs are water cooled as well, or an air cooled configuration WITH a home brewed VRM cooling fan, AND a great board, stand any chance of even semi-properly running those CPUs. They are garbage voltage leaking piles of heat miser (See here, for heat miser: https://christmas-specials.fandom.com/wiki/Heat_Miser ) offspring and should never have been released. The ONLY reason they ever made it into production was so that AMD could claim the top Mhz production CPU title.

The ONE way these can SOMETIMES still be useful is by manually underclocking them to FX-9370 or 8350 specifications including frequency, boost and voltage specifications and they will still require a far better board than the one the OP has.
