Can my PSU run a 48v fan at full capacity?

post #1 of 15
Thread Starter 
I was looking at putting 2 of these in a push/pull on my cooler. I know they would spin, but would I get full speed outta these fans? They're so cheap for the power that I'd love to have them.

'course you would.

Seriously? I wouldn't think 12v would be sufficient.
post #4 of 15
Starting Voltage : 24 VDC (25℃ POWER ON/OFF)

No, it wouldn't start spinning.

I am afraid you wont be able to run those fans on your PSU.

THe PSU has 3.3V, 5V and 12V outputs.

You could get an external PSU with a 48V output but to be honest - those fans will be very loud!

You can do it by attaching the ground (black lead) to the -12V of the PSU and the VCC (red lead) to the 12V rail.

But that would be dangerous, and a really stupid move to make.

Just get some regular 12V fans?

I'm sure there are plenty of quality 12V fans out there suitable for rad use. And I mean REAL 5,000RPM 120mm 12V fans, with ball bearings.

Just get 12v fans. A converter or separate PSU is a waste of money.

You would need at least this. 24vDC will get it running.
