I agree - fans don't draw enough current for that small difference to matter.

Question
Dell Poweredge Server 600SC - Replacement System Fan - Will this work?
Hi,
A few weeks ago I asked a question regarding a non-working Dell Poweredge 600SC rear system fan. The BIOS was reporting that the fan was not working, and upon inspection, the fan indeed was not functioning.
A forgot that Dell likes to use strange connectors, so I just picked up an Antec 120mm fan from CompUSA and installed it in the Dell. Since the Antec fan doesn't have the right type of connector to the motherboard to tell the motherboard that it is working, the BIOS still reports an error message that the fan is not working, but this new fan IS working. Since the wire connecting the fan to the motherboard doesn't fit, the computer is reporting this false positive.
Anyway, the fan in the server is a:
JMC/DATECH
1238-12HBTA-3
12V 1.5A
I called Dell, and this specific product they told me is out of its life cycle - no longer produced. Unsatisfied, I searched the Internet for replacement parts rather unsuccessfully. Off I went to eBay, and I was able to find a fan which to me, looks 99% like the broken fan from the server.
The fan I found on eBay is:
JMC
1238-12HBA
12Vdc
1.2A
The fans LOOK identical except for the slight model differentiation & amp difference. The new fan has the exact type of wire to connect to the motherboard, and agian, aside from a slight model name difference, they look identical.
My question is this:
The Antec fan had 2 wires; a power wire to connect to the power supply, and then the motherboard connector. Since the motherboard connector wire on the Antec fan doesn't fit, it's only plugged into the power supply. The old and new JMC fans only have 1 wire - the wire that connects directly to the motherboard. There is no power wire - I guess it gets its power right from the motherboard.
With the slight amp difference ion the fans (old fan 1.5A / new fan is 1.2A), is there a risk of damaging the motherboard, or am I worrying too much about nothing?

I would not worry about the Amp difference, particularly since it is lower. I've even cut the connectors off the the fans and switched them succesfully.
