| 820632 | 2009-10-14 23:42:00 | Hi All. Are all CPU fans & PSU fans capable of speed (Noise) control? If so, controlled from where & how? Thanks.. PJ |

| 820633 | 2009-10-15 00:06:00 | I wouldnt connect anything to a CPU or PSU fan to control it. Only case fans. Otherwise if it gets too slow, it'll probably shut the system down. To stop it from frying. If the PSU supports it, there maybe a switch on it. | Speedy Gonzales (78) | ||

Then you can set it from the BIOS Alternatively, you can use a fan controller Speedy: That isn't true-Depending on the HS usually decreasing the fan speed by 20% does not make the CPU temperature high at all. |

| 820635 | 2009-10-15 02:10:00 | cpu fans are best left to the built in motherboard support and require different fans. PSU's have there own built in system. nothing needs to be done. other case fans do not need to be a special type but the best way to control the speed is with PWM contoller. some are manual control (requires you to set the speed) others have temp sensors. there is also a few fans around with built in temp sensor and speed control. |

| 820636 | 2009-10-15 06:55:00 | Ok so the general opinion, as I see it , is to leave well alone if you dont know what you are doing. Bios changing is a case in point, I will not go there. Looks like I will have to look for quieter fans. Thanks anyway. PJ | Poppa John (284) | ||
| 820637 | 2009-10-15 07:51:00 | Hi Poppa John Speed Control of computer fans are possible but it is not the best way of doing things . You can leave well alone and suffer the noise problem . The best way of controlling fans is by switching on and off as required, electronically of course, ie temperture control . If you know how to assemble an electronic circuit or know someone who can, then it's amazing cheap to do so . Goto HERE ( . heatsink-guide . com/content . php?content=control . shtml" target="_blank">www . heatsink-guide . com) . Made this many times and the circuit works great . Hope this helps .

| 820638 | 2009-10-15 08:10:00 | Or get a fan controller, someone needs to install it on the front of the case. (And they'll also have to open the case and wire it up) | Speedy Gonzales (78) | ||
| 820639 | 2009-10-15 09:33:00 | Aimco Speedfan is the way to go. It just takes a little settting up to identify and lable the fans. | apsattv (7406) | ||
| 820640 | 2009-10-15 22:55:00 | Instead of just firing a shotgun at it, wouldn't it be a good idea to find out which fan(s) was/were causing the problem? It could be just a stuffed bearing in one fan, for example. Or clumps of fluffy stuff on the leading edges of the blades. I suggest you troubleshoot to find the worst culprit. Is the noise bad at startup but get better after running a while? Testing the PSU fan is easy - stick a pencil or thin stick (non-conducting) through the grill and stop the fan. What happens to the noise? Can you slow down/stop other fans to hear changes in sound levels? If you do this to the CPU fan be careful as overheating can occur quickly. May be best to leave this one! But if all the others are OK, then the noise must be the CPU fan, presumably. Of course, if you find stuffed bearings in fans, the next question is what to do about it!! But, at least, they should be de-fluffed. |
