AMD Phenom II x2 545
Ati Radeon HD 4830
4gb RAM

Speedfan tells me that after two hours of gaming my cpu reaches 60c and my gpu 65c. But my computer fans are so loud I can barely hear the game. When idle fans work silently. I am new here so excuse me if this thread doesn't belong here.

Then buy quieter fans. I suggest enermax silent or better yet, noctua silent. Those are very very quiet. but 60c is what you want your cpu to be at on max load. thats fine

I don't want to spend money on this soI'm lookig for other solutions other than buy new fans.

His fans change speed, so they're variable speed and managed by the BIOS in response to the temperatures it measures. The problem is they're running the fans at an unnecessarily high speed. Even if he got quieter fans, the motherboard would just run them at full speed and they'd still be noisy. Maybe not as noisy, but still unnecessarily noisy.

The first place he should check is his BIOS settings. Look for fan thresholds - at what temperature they kick up the fan RPMs - possibly under power management. Adjusting those so your fans go into hair dryer mode only if temps exceed 80 C should take care of the problem.

The better motherboards have this setting, but many do not. If yours doesn't, you've got four options:

- Since you already have Speedfan, see if its fan speed tweaking function works (that is the reason the utility was created in the first place). It doesn't work on every system I've tried, but it does work on most and lets you adjust the fan speed directly.

- See if there's a BIOS update - other users may have complained about the same problem (too-high fan RPM at low temps) and the manufacturer may have issued an update to the internal fan tables.

- If neither of those work, there are hacks online to swap the 12V and 5V leads to make your fan run at 5V and thus lower the RPM. Unfortunately this is often too low and some fans may not spin up, or they may now be too slow at low speed and your computer may run hotter when idle. There's another hack to move the ground lead to 5V so the fan gets 7V (12 - 5 = 7) which sort of gives you a middle ground. I think there's a device out there which plugs in between the fan and motherboard, and lets you dial in the voltage as well.

- Last recourse, buy new fans.
