Default 300R: starting voltages of the fans?

Hi,

I got a 300R a few months ago and I was really impressed of the good quality of this case, but the fans are a bit too noisy, especially the front one.

Because I do not have any resistors etc. here, I cannot check the starting voltages of the fans in the 300R and I don't want to waste money on buying a 5V adapter but the fan doesn't spin up.

So my question is: With which voltage the fans will spin up? 5V, 7V, 9V, 12V?

Thanks!

I am sorry but you would have to check that with a fan controller but normally they will be 7-12 Volt fans. I will ask the Case PM for a fan spec but it may be easier to use the fan controller built into the MB and try and slow the fan down to minimize the noise.s

Hi,

thanks for the reply! But I have no fan controller here and I also cannot regulate the voltages whith my MB UEFI/Software and it doesn't lower the RPM low enough, just a little bit.

Hi,

thanks a lot for your help! I think I will just use the 120mm fan with a 5V adapter and get an AF140 for the front!
