Hello,guys. So my problem is that my cpu is throttling. It is the fx8350, I havent overclocked it. The cpu cooler I use is deepcool maelatorm 240. The case is define r5.

So when im playing bf4 the cpu (not the cores) reaches 60 degrees it slows itself down and because of that from 100 fpa my game drops to 20-30 for like 2-3 seconds,which is soo annoying.

Can you please tell me a way to reduce the CPUTIN temperature?

Thank you in advance. I have tried so many things but nothing seems to help.

What is your motherboard?

Kevern_11 · Dec 18, 2015

turn up the fan speed on the rad if it isn't high enough. Also make sure the pump is running at max speed.

Kevern_11 · Dec 18, 2015

If it isn't getting the full 12v from the fan header the pump is plugged into that could also affect performance and temps.

Mutkatt · Dec 18, 2015

I think the pump is at full speed. It is connected to the 3 pin headee of the mobo. The mobo is asrock 970 pro3 r2.0 and I run the fans at 80 %there is no difference if they are at 100. The temperatures of the cores drop to like 10 degrees when idle to 35, on load the cores temp goes up to 47-49 but very rarely.

Kevern_11 · Dec 18, 2015

but the 8350 doesn't usually throttle till around 65 degrees celcius...

DonkeyOatie · Dec 18, 2015

The motherboard you are using has a less robust power delivery system and is not really suitable for running a FX8350 at stock and certainly not for overclocking it. It is possible that your throttling is because of motherboard overheating. Going to a liquid cooler makes this problem worse because there is no motherboard cooling from the radiator fans. One thing to do would be to open up the case and see if it helps. Or you can temporarily zip ties a case fan to cool the motherboard. If this helps, then it is a sign that the motherboard is limiting your CPU.

Kevern_11 · Dec 18, 2015

if it is really running hot then you may need to underclock

Mutkatt · Dec 18, 2015

But the frequency of the cpu doesnt slow down when the CPUTIN temperature is not reaching the 60 degree temp. I will try this. I tjink the define r5 case fans do move some air but.. This throttling is really annoying.

DonkeyOatie · Dec 18, 2015

If it is a motherboard issue, the CPU core temperatures will not necessarily reflect this. Measuring temperatures is problematic because AMD uses algorithms and indirect methods, other than direct thermocouples. What does AMD's Overdrive say?

Mutkatt · Dec 18, 2015

I havent checked amd overdrive, will do tonight

Mutkat · Dec 18, 2015

http://prntscr.com/9ftkbc There is the pic of overdrive and HWmonitors current temp when idle.

Mutkat · Dec 18, 2015

The temperatures vary. when Im not using the PC ( like I mean its only the HWmonitor without me doing anything, the temps go to 10 degrees , which is perfect for me, and when Im browsing they go to like 30-40 sometimes and then back down to like 15

Mutkat · Dec 18, 2015

Ok, so here are some pics after playing bf4 for 10 minutes. the first one :

http://prntscr.com/9ftubw

second one ( at the time of throttling... this time it started at 59 degrees) :

http://prntscr.com/9ftvhd

and the third one - after I exited the game ( Look at the temperatures):

http://prntscr.com/9fty44

Mutkat · Dec 18, 2015

Ok. see what happened now. I think that is some kind of a bug in the software ( HWmonitor) cause... take a look:

http://prntscr.com/9fu0ke

FIrst: what is TMPIN4 and second - How come this will happen without completely destroying the CPU and it doesnt show in the other programs

DonkeyOatie · Dec 18, 2015

Forget HWMonitor. As I said, only Overdrive is vaguely reliable.

Look at your second pic. You CPU has slowed down, your voltage has dropped down to less than 0.9V. I think that's motherboard throttling.

Mutkatt · Dec 18, 2015

But the mobo temperature in the other program is just 33 degrees or smth like that

Mutkatt · Dec 18, 2015

Oh, I understand. It is not suitable for the fx 8350.. Sooo I have to change the mobo? Are you sure that this is going to fix the problem? Somewhere ive read that the 970 series are not good for 8 core CPUS and that im supposed to get 99series or 990 something like that

DonkeyOatie · Dec 19, 2015

1. NO. I'm NOT CERTAIN replacing the motherboard will fix the problem. I'd be more certain if you could cool the motherboard with a fan and see if it helps.

There are several possibilities, I'm working on the motherboard, Kevern_11 is working on your cooler.

The challenge with this sort of problem is to correctly identify it. It requires reliable data and careful testing and adjusting.

I KNOW that motherboard is not suitable for doing what you want (like using a Mini Cooper as a taxi-cab). The board's power phases will run the chip, but not at the levels you want (stock + gaming stress).

I'd like to get an idea of the throttling, if any. Could you please download the free 3DMark benchmark software and run all four parts, Ice Storm, Cloud Gate, Sky Diver, and Fire Strike, and report to us the Graphics, Physics, and Combined scores. We can then compare those with other similar systems and from the differences, identify the limits of your system.

What is your GPU?

Mutkatt · Dec 19, 2015

My gpu is the Sapphire r9 390 Nitro OC 1040 mhz. Non overclocked by me. I will run the tests tonight, cause im at work right now. And thanks for helping me

Mutkat · Dec 19, 2015

So, guys, here are the results. I will post some pictures:

Ice Storm 1.2 : http://prntscr.com/9g61vo

Cloud Gate 1.1: http://prntscr.com/9g64a0

Sky Diver 1.0 : http://prntscr.com/9g68a2

Fire Strike 1.1 : http://prntscr.com/9g6co3

Guys, I am almost sure that the northbridge ( if even possible ) is slowing down my CPU. It is absolutely hot to touch and now ( i opened up my case) the throttling or the fps drop appeared at 56 degrees of the CPU socket ! So Im definitely getting a 40mm fan and I will try yo put it onto the heatsink

DonkeyOatie · Dec 19, 2015

Thanks.

Looking at the Fire Strike and comparing to an 8Gb, FX 8350 running at 4.0Ghz with a MSI 390 (don't know exactly which one we have:

Graphics: 13497 vs 12402
Physics: 8457 vs 7420
Combined: 3252 vs 2871
Benchmark: 9610 vs 8657

What model of GPU and what speed is your CPU?

Mutkatt · Dec 19, 2015

Sapphire R9 390 Nitro OC edition at 1040 mhz and fx 8350 4ghz.

DonkeyOatie · Dec 20, 2015

Great. So you can see that your CPU, which drives the Physics is definitely running slow and throttling in some way. It may also be limiting the GPU. If you can get a fan blowing on the motherboard, give it time to cool and re-run the same benchmark and see what the difference is. Hopefully, you will get another 1000 or so on your Physics.

Hello,guys. So my problem is that my cpu is throttling. It is the fx8350, I havent overclocked it. The cpu cooler I use is
