Case Fans

[ssu101]

I recently built a computer using the In Win Dragon slayer micro-atx case. For those not familiar with it, it contains 4 fans inside it. My only problem with the case is its so damn loud. It seems as if all of the fans are running full speed at all times (even when I boot). One of the fans is connected to the mobo, and the other 3 are connected directly to the PSU. So, my question is, should these fans be going full speed at all times (If not, how can I fix this)?

Thanks in advance

Disconnect all but one rear exhaust fan and see if your temperatures remain acceptable.

what is an acceptable temperature, and what should I use to measure the temps? I have an ati gpu and amd processor btw.

Also, I havent overclocked anything and dont plan to

Download SpeedFan and measure your CPU, GPU and motherboard temperatures. You can buy fan speed controllers so your fans are not running at 100% all the time, but if you do this then you must keep track of your temperatures. You also probably invalidate your warranty.

I bet its the 80mm and 90mm fans that are making all the noise and not the 140mm fan on top of the case. http://www.alpha-electronics.net/pro...p?prod=CSIW-DS. Do as glc suggested by unplugging the two smaller fans and see what happens. If that does not work then is there any chance of changing the two small fans out to 120mm fans and slowing them down?

These are the numbers that came up when I ran speedfan while browsin the internet (idle temp?). Can somone explain how high the numbers should be, and what the important numbers are in the picture?

Forgive me for my ignorance, but why would swapping out smaller fans for bigger ones decrease the noise? Also, do you think I really need the 80 mm hdd fan, or is it pointless.

What brand and model are your motherboard and video card? What is your CPU? You are better off running manufacturer's utilities to monitor temperatures, Speedfan quite often can't read sensors correctly. Use this for checking hard drive temps:

Download HDD Thermometer 1.3 Free - HDD Thermometer monitors you hard disks temperature and prevent overheating. - Softpedia

Larger fans generally run slower, moving just as much air and running quieter in the process.

MOBO: Asus M4A785TD-M EVO
GPU Sapphire Vapor-X HD5770 1GB
CPU: AMD Phenom II X4 955 Black edition

What temperatures do you think are acceptable?

[ssu101]

HDD Thermometer says my hdd temp is 37C(98F).

That's fine, a reasonable HDD limit is 50. Install Asus Probe - it's on your motherboard support CD/DVD. ATI or Sapphire should have something that will report GPU temps.

A reasonable CPU limit is 60 and motherboard 50. GPU depends on the particular GPU, I prefer to see them under 80.

here are the results on asus probe II when browsing the internet.

After stressing the system for around 10 minutes (by playing counter strike source) the cpu temp shoots up to about 51C, and the mobo temp remains at 41C or so. What tool to you recommend to view gpu temperatures?

[glc]

Those temperatures are fine.

A 5770 is safe to 105+c but I wouldn't want to run it over 90.
