Hello everyone,

I just built this new budget Gaming PC but I believe is very noisy. I had an old HP pavillion and to my surprise the old one is quieter than this new PC. I thought this one should be quieter. Here are the specs;

Power Supply : Cooler Master eXtreme Power Plus 500w Power Supply

Motherboard: ASUS M5A97 R2.0 AM3+ AMD 970 SATA

CPU: AMD FD6300WMHKBOX FX-6300 6-Core Processor

Memory: Corsair Vengeance 8 GB ( 2 x 4 GB ) DDR3 1600 MHz (PC3 12800) 240-Pin DDR3

HDD: WD Blue 1 TB Desktop Hard Drive: 3.5 Inch, 7200 RPM

Video Card: Sapphire Radeon HD 7790 OC 1GB DDR5

Case: Cooler Master Elite 431 Plus - Mid Tower Computer Case


is this normal? is there anything I could do to make the fans quieter?


Thanks a lot for all your help and suggestions.

I forgot to mention that I added a radeon 5450 HD to the old Pavillion.

Well, is not that super loud, just louder than the pavillion.

Your gaming rig is throwing a lot more heat then the HP. You can fix that.

Turn down the fans if you don't need the cooling. There are several techniques to lower the voltage to fixed RPM fans that silence them. Underclock the video card to reduce card fan noise by reducing the heat from the vide ard that the expense of some performance. You can get 80% of the performance for 50% of the heat.

If you don't want to go slower then you need to get a case designed for low noise and high heat removal. Google it then build in new case.

If you want to stay in your current case and not go slower then try to find which fans are the noisiest. If it's video card you are stuck (replacing heat sink / fan is a pain on video card). If it's case fans then google quiet case fans - they are easy to swap in if they are the same size.

Yes, I guess I need to add the big luminous case fan.

The case fan is connected directly to the PSU.

Should I buy a fan controller or I can just lower the RPM of the fans. How low can I go without overheating? can I use a program like speedfan or just adjust the speed from the BIOS?

The only fans connected directly to the motherboard are the CPU and Video card Fans. Can I lower the speed on those or not recommended?

The strange thing is that sometimes I can hear the fans when they're not needed ( just running a few windows of Firefox, IE and Chrome), and go crazy when I play a regular game like left for dead 2... Maybe I can play with the BIOS settings.

Which cable should I use to make the case fan longer to be able to plug it into the motherboard?

re: "..You case fan CANNOT change speeds because it id plugged into the PSU...."

Many case fans like mine plug into 4 pin MB connectors where fan speed is controlled by Pulse-width modulation. A tool like 'speedfan' can read the RPM of many MB controlled fans.
