Question 1

What is the input current, or ampere rating, of this fan? My motherboard header allows 1 amp max and I'm wondering if I can put two of these on one header using a splitter.

Accepted Answer

I'm sorry, but I no longer have the packaging for this product; so I can't provide the manufacturer's specifications.

Since this is a PWM fan, I wouldn't trust an ammeter reading.

I would recommend using a powered PWM splitter like that available from SWIFTECH.

Question 2

I have a question about the power inputs. If I use only the 12V connections, will this operate in both speeds based on temperature? That is, does it have a built in thermistor, or does it need voltage control through the wires. I'm planning to use these for Solar applications, and my previous fan choice  ( a CPU fan) only needs 12V, because the thermistor and built in circuitry control the fan's speed based on temperature. Thank you, Jerry

Thanks Dmitry, I'm more interested in having the capabilty of two or three speeds, this matches the rising temperatures well. Are there any fans, that have the circuitry built in, that only need
a 12v source? For example the fan I was using is a DC brushless MODEL 3610KL-04W-B66 (Dell CPU fan). Is there a 140mm fan that matches that spec? Thank you

Question 3

How long is the wire? Is there an extension wire available for this fan?

Accepted Answer

it is a 4 pin pwm type connector, so any extension you use would need to fit that connection.
*I used a 3 pin extension and cut out the right sidewall on the extension connector to accommodate the 4 pin pwm, works great. I used a razor knife and a flat tipped pliers.

Question 4

Where can I buy more rubber connectors or "screws"?

Question 5

would this connect to a 4pin motherboard hook ups?

Accepted Answer

Yes it has four wires coming out of it.
