Hey guys ,

I got this new x dream k640 Cooler,i installed it on my K8N mobo , when i turn on the power switch i get error message in BIOS says 'incorrect CPU fan speed' , i went into the bios and saw the fan speed 400 and increasing slowly, I know the cooler fan is controlled by Thermistor, the fan takes a while to reach the RPM of 1200, I want to know how to fix this issue.

Well, you can disable the bios warning for the cpu fan.

And since this cooler uses a thermistor, it will control itself.

How can i disable the message in BIOS and i want to know is it okay if the RPM of the CPU fan starts at 400 when i power up the CPU, and also the Cooler noise level in the manual it says 19decibals but its almost equal to the

noise of OEM fan.

Depends on what motherboard you have.

But if it runs at 400rpm and it's way to noisy, it seems like it's a faulty one.

On page 2-27 of the manual, which setting is activated?

But you say the fan is noisy? That means it's broken :(

(Also means, that you should apply for RMA)

I have enabled the following in the BIOS:

1. Cool and quiet enabled : Page 50 in the manual

2. Aperture size 512mb the bios default is 128mb :Page 52 in the manual

3. ACPI support 2.0 enabled: Page 58 in the manual

4. CPU fan speed as reported by the BIOS :Page 60 in the Manual

5. Smart Q-FAN Function disabled :Page 61 in the Manual

Rest settings are all factory defaults. And about the fan being noisy i think its my GPU fan not the cooler.
