Reference 5 and 6 series fans

post #1 of 4
Thread Starter 
This is for the reference design radial fans. Has anyone attempted trying a higher rotation fan on a 5850? I have a 6970 which will have a non-used fan.

5850 fan is a 1.2 amp AVC branded piece.
6970 is a 2.0 amp Foxconn model.

Both are PWM, and I'm pretty sure the 5850 would be up to the task, but eyeballing alone hasn't given enough info, so I'm wondering if anyone else has tried (or even thought of) this. The 6970/6950 fan seems to be the same unit the 5970 uses. I imagine a little extra airflow on the 5850 wouldn't hurt.

I've put a 4870X2 fan in a 5870 before without any problems (worked better).
The other fan died out of nowhere.

Both fans are plenty good...the only thing I worry about is the amperage draw on the card. The cards are similarly designed for fan control, but not identical, and I haven't gone through dissecting them.

What amperage is that 4870x2 fan?

I don't remember, but the 4870X2 fan had a higher amperage.
I'm sure putting a 6970 fan in the 5850 would be fine (variable power draw for aftermarket fans).
