I have a FX-8320 stock with a Hyper TX3 cooler, Asrock 970 Extreme 4 and Shappire 7870. I have the latest drivers for CPU and Bios

When i play a game the CPU run at 3.7 Ghz (normal) but every minute it downclock itself for few second to 1.4 Ghz. This give me about 10 fps in the game for few second and it is very annoying.

The CPU get about 60º while playing, max 70º.

That temperature is a bit high, sounds like it is throttling down to prevent overheating.

In your OS, Control Panel > Power Options try setting it to high performance and see what it does.  You might want to try and remove and reapply some new TIM on the CPU heatsink.  Could have too much or too little on it.

Yep.. It's seems very high, considering you have an aftermarket cooler, and you're not OCing it..

My guesses:

1.- Bad case airflow + high room temps. Well, regarding the first, you could add more fans. I don't know what to propose to you for the second one...

2.- CPU cooler not properly seated/bad TIM (thermal compound). Solution: desassembly it, clean both surfaces with alcohol very carefully, and then put good TIM (like MX-5), and then re-seat the CPU cooler properly. While you're doing it, clean the aluminium fins too..

3.- Bad PSU. Since you don't listed it, a bad PSU could deliver improperly voltage, which leads to an overheating.

 

Check this things out, and then come back again...

 

Best regards...

I reapplied the TIM (i put too much TIM the previous time) and i reduced the temperature 5º, but the CPU was still downclocking to 1.4 Ghz when get around 67º, so i disabled the CPU turbo and now it only gets 3.5 Ghz but its around 52º while playing so it doesnt downclock and i can play.

Anyway i will need a new CPU cooler and 1 or 2 more fans for improve the temperature.

Thanks

I would suggest a closed loop liquid cooler such as the Corsair H series. They are quiet, efficient, inexpensive, and you won't regret moving away from air one bit.
