Question 1

Would it be wise to use this to replace the stock fan on my stock heatsink for my AMD FX-6300? I really would like it to have a quieter fan. If not, can anyone recommend a low cost replacement?

Accepted Answer

I have put 3 of them in my computer case. 2 are of the pwm type (variable speed) and one is not. If your cpu cooler uses 80mm fans then I would suggest using the non pwm type  (so you will max rpm's all the time). they are very quiet and seem to do a very good job (I use a program called hwmonitor to monitor the rpm speed and temps of all my equipment and have been very pleased with the results).

Question 2

Does this product come with 4 Pin molex to 3 pin adapter?

Accepted Answer

No.  It comes with 3 pin, you can connect to motherboards cpu fan plug if you have an extra, (cpu_fan2) or cha_fan2 or pwrfan if you have those on your motherboard.

Question 3

I am looking for a quiet fan for a future project, i realize no fan is quiet at full speed, but will run undervolted @ 5v and still move a little air with a filter?

Hey chad I'm using four of these in a silverstone ml03b htpc case with Intel I3 setup and they move decent a  though the case at 5 volt . I tried the bgears 80mm fan filter but not a good combination cause the kill the air floor.

Question 4

Being a 3-pin fan. Does it come with a resistor / voltage reducer to reduce fan speed?

Can all motherboard control fan speed for 3 pin fans? Or do I need 4 pin PWM?

Accepted Answer

>Does it come with a resistor / voltage reducer to reduce fan speed?

No.  As you mention, the speed of the fan is controlled by the voltage supplied by the mainboard.

>Can all motherboard control fan speed for 3 pin fans? Or do I need 4 pin PWM?

The ability of each mainboard to control fan speed varies significantly from model to model.  Some allow you to associate fan speed with temp levels, some have a few presets (ie low, medium, high).  If your mainboard supports PWM fans, I recommend using them as they are much more dynamic.  Also, if you connect a 3-pin fan to a PWM header, you may not be able to adjust the fan speed at all.
