Loud CPU Fan

[dvdmcehnry]

My CPU fan starts going around 5,000 RPM; after playing a game for about 10 mins.

I tested fan speed and CPU temp using CPUID HWMonitor:

• 
  CPU Temp:38 C
  Fan RPM: anywhere from 4,000-5,300 RPM

My build is:

• 
  NZXT Phantom 820
  Rosewill Capstone-750W
  ASUS Crossgair Formula-Z
  AMD FX-8350 Black Edition
  G.Skill 16 GB (8GBx2) DDR3 1600
  EVGA GTX 980 4GB GDDR5

I am not overclocking my build. So I did stick with the stock fan (now I know why that is frowned upon...)

Games that this happens to:

• 
  Arma 3
  Cities: Skylines
  Company of Heroes 2
  Elder Scrolls Online
  Skyrim (even without mods)
  Civilization V
  South Park: The Stick of Truth
  StarDrive2
  Total War: ROME 2
  Total War: SHOGUN 2
  XCOM Enemy Unknown
  Fallout 3 (even without mods)
  Warframe
  FarCry 3
  Sims
  Battlefield 4
  Dead Space 3

I did set my fan to Silent mode (after those number were taken) in the BIOS, and that helped a lot but now I am worried that the CPU will overheat.

Is there anything that I can do short of buying a better CPU fan?

Sorry this is so long.... Thanks in advance!

Buy a good aftermarket fan. It will be quieter and cool better.

OK, to be sure you are not overheating/throttling download AMD Overdrive and look at the thermal margin. This temp tells you how far away from throttling you are. Once the temp reaches 0°C, turns red and starts going up in the red your CPU will start to lower the clock speeds.

IF changing to silent mode hurts you, this will show it. As for quieter, this usually means a different CPU cooler. The stock coolers are barely enough to keep the CPU from throttling in a high airflow case. Usually when the CPU fan hits 5000 RPM it is reaching near its max speed and the CPU is hot. HWmonitor can not read AMD CPU temps properly. These programs use a mathematical algorithm that uses wattage drawn, core speed and load to calculate the temp and not a Temp sensor. This is why I mentioned AMD Overdrive for reading the thermal margin.

Thank you for this it was very helpful! A ton better than CPUID.

I will have to get a new cooling setup.

Looking for recommendations on a configuration:

Should I do a push-pull setup or would just a push or pull setup work?

Thanks again in advance

I'm not sure exactly what you have in mind for what you want to do so that may explain my next comment. A stock cooler can not do a push pull configuration. This would require a different cooler completely. As an example of a cheap cooler is the CoolerMaster Hyper 212 evo. These are usually $35 at there max price and can be found for $25 on sale and will cool much better than the stock cooler. On this cooler you could do a push pull configuration but there treally is no advantage to it as the temp drop is only 2° max.
