[HELP] FX-8350 Heat issues

I am very unsure whether my temperatures are correct for my CPU, CPU Cooler, and Motherboard. I am very nervous at my temperatures if they're too high.

My computer starts at goes as low as 10 C then idles at 40 C (HWMonitor), 24-32 C (Core Temp - this varies a lot).

Under heavy gaming (Crysis 2 - Ultra settings) - It goes to 65 C (HW Monitor) and 50-55 C (Core Temp).

I am unsure what temperatures are real, and what I can do to lower it.

Also I now have recently noticed I have Overclocked without doing much? 4.0 GHz to 4.33 GHz, I might have accidentally clicked OC Tuner, will that do something?

Need to learn my Motherboard/CPU.

Here are my computer spec's -

MOTHERBOARD: Asus M5A97 LE 2.0
CPU: AMD FX-8350 Eight-Core (Stock)
RAM: Corsair 8GB (4 GB x2)
GPU: XFX Radeon HD 6950 2 GB DDR5 (Overlclocked to a 6970)
CPU Cooler: Arctic Cooling Freezer 7 Pro Rev 2
PSU: OCZ ZS Series 750W
Case: Sharkoon T9 ATX Midi Tower Case

(Image below is at start-up/wake-up, also from last night's gaming)


Thanks for any help provided.

I think you're good.

There is no official spec that I can find for the FX8350 -- I would suggest using the Asus utility, and keeping it (and your BIOS) up-to-date.

I am unsure because at idle now when the computer is warmed up and idle it is sitting at currently 45 C, when I go into a game it might rocket up to 65/68 C.

I am just hoping it doesn't burn up/damage the CPU.

Your CPU is a silicone processor. These things are tough, generally surviving temperatures of 90-100 celcius. You should be fine so long as you stay below 70 c, as the piledriver architecture begins to throttle if it gets above this temperature.

How can I go about keep it below 70 C? I am a very heavy gamer, as well as use Fraps to record game footage.

Hey fellow FX-8350 owner here and here's some advice. Open up task manager and look up your resource management. If you're able to see it not throttle the CPU's maximum frequency then you should be fine. It will throttle itself long before it overheats and if you ever get to the point of it overheating, it will just shut itself off. The only way to really kill it is to manually set the voltage to like 2.0 and keep forcing that into it until it dies.

The best way to keep it from overheating is to get a good heatsink, I recommend things like the h80/h90 from corsair or some of the other closed loop water coolers. I'm using an h100, and am pretty alright with temps.

Since it doesn't already crest 70 with what you're doing here, it should be fine. If you're worried about it, you could buy an aftermarket cooler. Here's one that people seem to like:

I am using the Arctic Cooler 7 rev 2, is it not good enough for my CPU?

If so, I'll purchase the one you suggested, and can you also suggest good thermal paste, I have TG-1 Thermaltake, but unsure if it's good enough (it is what I am using currently.

How do I find the resource management? Silly question possibly. Also what will that check?

Task Manager. Performance. Open Resource Monitor. I'm doing this on Windows 8, so the names of them might be a little bit different. Saw mine was throttling itself that way and I'm going to have to redo the thermal paste and make sure the contact is solid.

I am using Windows 8 too.

How do I know if my CPU is throttling?



I have taken an image.

Go into your bios and disable all forms of power saving. Then go into AMD Vision Engine Control. Go to Performance. CPU Power. You'll want to make it so the sliders are close together meaning 100-100. If you've overclocked the base speed then this is pointless, but if you've overclocked the turbo core than this is helpful. You'll notice how the maximum frequency dips there in the top graph. It's a small dip so I'm guessing you still have turbo core enabled. When you start cranking it up you'll maybe start to hit throttling issues. This could be from too much heat, too much voltage, or too little cooling provided. Too little cooling comes from either the cooler being insufficient, the contact being insufficient, or the airflow being insufficient.

Going through the process in reserve order, you'll have insufficient airflow is your intake or exhaust vents are obstructed or filled with dust. You'll have insufficient contact if you notice sudden spikes in heat or large dips in performance. This comes from heat rising getting trapped, still rising, and then eventually dissipating in a sudden large visible output. Insufficient cooling is when the temperature just sky rockets. The cooler just isn't able to handle all the heat and dissipates what it can for the rest to naturally build up until you've overheated.

If you're already using after-market cooling and not cresting 70, then you should be fine.

I really do hope so! Thanks so much for your help, and others!

I have a Sharkoon T9 Midi case, and it has no airflow at the top of the case , my fan is directly above that, what CPU Cooler or a cooler can I get to make sure it has good airflow or even something else, I can try change my cpu cooler around then it hits my graphics card, any ideas?

You can get any of the 120 MM closed looped coolers, so h80, h60, from corsair not sure about the names of the new Eiseinhowers or Seidon. Just pop on the cooler and replaced the fan directly beside the CPU with the the radiator. Wouldn't have to worry about ram and the like. Not sure about the exact dimensions of your case and most air coolers vary. So you just gotta make sure there's enough room. I used a V8 for my old fx-8150 and that hit 4.7. So it's up to your for your choice of cooler as any big tower will perform pretty well. I just like the h80/h60.

I'll go with what you've said, h60/h80 can you check if they both fit in my case comfortably? Price and will it fit, I need to be confirmed. Thanks very much.

I use the H80 with my FX8350 and it keeps it pretty cool. I do idle around 38c but I also I have a overclock of 4.8 on the chip. So pretty good idle temp considering, while gaming I hit about 55c.

I'll use that then, will it fit in my case? How about H60?

I just pulled up a picture of the inside of your case, it looks like it would fit but it will be a tight fit. You would have to add the radiator and extra fan and hopefully it doesn't extend out to far and you have clearance to put fan on the processor.

He'll be fine. There's enough space to fit H80 in there even H80i with push/pull, However, if you are concerned about noise too then you might as well grab the Noctua D14 as it keeps up with the best closed loop watercoolers and it has gone down in price. And right now your temps are fine no need to worry unless you plan to OC. going around 60-72 is ok so you have nothing to worry about.

H60 will fit fine?

So for now my computer will last a while with the current CPU Cooler and temperatures? How many months do you reckon before an upgrade to the H60? (Just only worried about the fitting for it).
