Hey, this is my first and probably only thread on this forum.

Recently, I have bought a new motherboard to support the 4ghz my AMD fx-8350 can reach. My old motherboard could only use the CPU to 2.8ghz. I reapplied thermal paste in the new mobo and everything seemed fine, except when I opened the ASROCK Extreme Tuning Utility I saw that my CPU was at Temperatures ranging from 50c to 77c. The fans are now unbearably loud and it doesn't even help the temperatures at all. This is idle, bearing in mind. I am too afraid of running any games because of the pc in idle and I am just stumped on what to do.

I am getting a new cooler tommorrow, upgrading the stock one. "COOLERMASTER HYPER 212 Evo RR-212E-16PK-R1 120 mm CPU Cooler"

The stock one is incredibly dusty, could this be it? Could it be my application of Thermal Paste? I used Artic Silver 5 and the middle dot technique (with no tanning).

What are my options here?
 
Your problem likely was never the motherboard. Your stock cooler and likely lack of airflow was the issue. Unless the VRMs hit the throttle temperature, there would be no reason why the motherboard would max your clock at 2.8GHz. Clearing the dust will help but those idle temps are really high for an fx chip considering the idle temp normally shows as something silly due to the sensor only showing accurate readings as it approaches throttling core temp.

What was your old motherboard and what is your new one?

Clear all the extra dust and tidy the cables up. Make sure there is plenty of airflow. Take a picture of the internals and post here if you are unsure. How did you apply the paste? You could have bad coverage or poor contact, so the already poor stock fan is running inefficiently.

The new motherboard is an "ASRock 970 Extreme3 R2.0" and the old motherboard was a gigabyte one that was extremely bad, I couldn't find it anywhere on the internet. It was a gigabyte one and came with a stock PC somewhere from china that I got off Amazon. It is the PC I have upgraded since. It only supported 95w processors and that is the reason it was knocking down my clock speed to 2.8ghz. I believe reading a thread about it on this website.

My cable management is poor but there are no wires in the way of the CPU fan or any other fans.

How would I go about checking power saving features, should they be on/off? How do I check clock is stepping down at idle?

Forgive me, I am not that technologically advanced. I am used to just sticking in the components and it working straight away. I greatly appreciate your advice and replies.

Tomorrow I will be cleaning all dust in my PC and installing the "COOLERMASTER HYPER 212 Evo RR-212E-16PK-R1 120 mm CPU Cooler".

I had a feeling you ended up with that motherboard. Do yourself a favour and return it. That board is a typical example of flashy marketing that is not up to the job of the more hungry processors. The power phasing is 4+1 and has no proper heatsink for the VRMs to dissipate the heat that is being delivered to the CPU. The new cooler will fix your CPU temps and a better motherboard will sort out your throttling due to toasty VRMs.

What is the mobo budget if you can sort out a return?
 
I agree with Avenged7Fold, the power phasing on that board is poor and with inadequate VRM/MOSFET cooling it will get hot because the FX chips pound the VRMs. Especially so when the phasing is only 4+1. The Evo 212 will sort out your CPU temps, but the system will probably still throttle because the VRMs can't cope with the heat.

Looking at the Asrock site, the CPU support list specifies a top-down cooler which blows air onto the surrounding components. They're basically admitting their design doesn't have sufficient cooling for use with FX chips.

As an example, this board has a heatsink that covers both the VRMs and the MOSFETs, which get hot.
 
I'm going to have to wait until tomorrow to get my new cooler until I am able to make any decisions. I am likely not going to be able to return the motherboard because my mother is opposed to the idea.

Thanks for the input, I will update tomorrow.
 
This is Frenchcheese's dad (he's 13) and I understand the issues you are discussing here, but I would like to test the motherboard with the new cpu cooler installed before I consider sending it back. Does anyone here actually know how much it costs to send a motherboard back? I am liable for that cost, Overclockers will not refund me on that. But thanks for the advice anyway...
 
At least there is a heatsink there on the motherboard. There are some awful boards with just the bare mosfets.

4+1 phases is probably fine for running the 8350 at stock. I'd only consider returning the board if the processor doesn't work as intended once you re-attach the cpu cooler.

AMD processors have something called cool n quiet on by default which will downclock the processor when idle.

You need to put the processor under load with a stress test application like OCCT or Prime95. While that's running, you'd check the temps with HWMonitor and use CPU-Z to check that it's running at the correct frequency.
 
I have cool and quite enabled. When idle, my task manager said I was using 10% of my CPU and ASRock Extreme Tuner said my CPU was 50 degrees with the fans easily over 50 db. The RPM on my CPU fan was 4000rpm.

Below is an image of my CPU, would the dust have this significant of an impact?

Yeah, you're nearly getting into dust bunny territory! Dust like that can have an effect. A new cooler and a good clean out may well fix the problem to a point where the temperatures are satisfactory. The stock AMD and Intel coolers are notoriously poor with the higher-end chips, so it isn't helping.

Your cable management isn't actually that bad. There's good airflow between the front and the back in the CPU area. You should see my Pentium build...

It's a shame that the AMD chips hammer the VRMs, but bear in mind that the AMD chips aren't as efficient as Intel and need to draw more power. For the money though, they're great value. My dad's FX 6300 actually outperforms my i5 4670K in photoshop!

For thermal paste, I use the rice grain method, as a pea-size amouunt is just a little large.
 
Hi firstly what psu are you running, and secondly you are using the 4 pin atx power connector when the motherboard has an 8 pin socket. Does the psu have an 8 pin atx power connector, if not then you shouldn't really use an fx8 series processor using just a 4 pin due to current draw. The stock cooler is pretty crap but it shouldn't cause high idle temps apart from the dust lol.

As for your idle temps could you download hwmonitor and cpu-z and do a screen print of the readout in hwmonitor and cpu-z at idle.
I'd like to see what voltage is being applied at idle and at load.

Also your memory should be installed in slots a1 and b1 so that it runs in dual channel mode.

Good. Still worth checking how low the clock speed and multiplier go when idle. I usually just use CPU-Z but many monitoring programs will tell you this.

And get that dust cleaned out!
 
Alright cheers will tell you how it is later, thanks for all the advice and help. The PSU is really bad and I am probably gonna upgrade just so I can have a 960 next year (I needed to get a 750ti last year because it didn't have the necessary pins).

Again I really appreciate the help you are giving me!
 
Monitor your VRM temps, it could be the cooler can just about supply enough cooling power to the components. I understand that your mother might be against returning it due to delivery expense but Asrock am3+ boards gained a bit of a reputation of 'exploding' or 'burning' VRMs when paired with the toastier hungrier chips. The combination of an 8150 and your board was notorious at one point for causing issues related to throttling.

Though i doubt your PC is in danger of catching fire, if the cooler doesn't cool the surrounding components, you will likely throttle at stock and get much less out of the processor than it should give. Keep an eye on VRM temperatures with the motherboard software if you have it or with third party software. Make sure you keep it clear of dust too, VRMs can operate at much higher temperatures (up to 130 depending on the VRMs) than other components and no heat sinks cause them to settle on very high temps under load. Risk of something going bad is much greater if you have dust balls sitting on your red hot VRMs.

Your PSU is fine for now but when you decide to get a GPU, look at replacing it with something reliable with a good OEM brand.
 
99% sure its dust between the fan and heat sink that's causing the issues. The stock fan doesnt have enough blow to push air past that blockage.

VRM throttling won't kick in unless you are pounding the bench marks or playing a well multi threaded game.

Installing 212 will I believe fix your current issues, but a tower cooler is going to further exaggerate VRM cooling issues as the airflow will be directed over them.

4+1 sets CAN take FX chips using aggressive focused cooling on them. I managed to get a 8230 on that mobo to 4ghz stable by bracketing a 25mm high rpm fan directly over the VRM heat sinks.

TLDR: Take off stock fan, clean dust out properly, fit a decent higher flow rate fan. Send 212 back.
 
If he just bought the motherboard, then no point in messing around with ghetto mods just to make his board adequate. Better off spending the postage to get a more suitable one, its not like an adequate board would cost much more.

If OP is going to be sending anything back, i would send the board over the cooler, rather than the cooler to make up for the boards shortcomings.
