Fan control on accelero IV (1660ti) Help

[Perm1]

Hello all hope all is well. Was hoping someone might be able to help with an issue I having.

I currently have a Accellero IV cooler on my 1660ti, the fans connect to 7v or 12v via molex. I recently bought an adaptor so I can control the fans by plugging them on the GPU pcb.

I installed the cable the other day just to test and I am certain I seen GPU fan speed 800rpm on NZXT app when it open on startup and fans worked ok.

Anyway today I went to install everyting properly and do some cable management but I noticed the adaptors red wire was loose. So I removed the pin and reattached it and applied a tiny piece of solder to wire/pin.

I reinstalled GPU with cable and fans seem to be running near or at full speed. I tried to use Riva tuner and Asus tweak to change the fan speed but it never seems to change at all.

Do you think me reconnecting wire could cause this or has anyone else controlled a accelero extreme 4 via the GPUs pcb fan connector with adaptor?

If it were an issue with the red wire they'd not be running at all.

The PWM wire, sometimes blue or green would more likely be where the issue lies. A non connection on this circuit would mean the fan would run at full speed.

I'm not sure what this adaptor you speak of is doing. Is it a mini PWM to normal PWM with all 4 wires?

Hey thanks for reply. Its adaptor that connects the mini fan connector from the accelero fans to the graphics card. 6pin to gpu mini, it has 4 wires for PWM. Fans connect to molex 7V but am fussy and like to be able pull molex. Thanks again

Ok. It might be the yellow wire then.

Check the connection. You could route power from a molex if you want but it should be 12v directly and it'd be a right fiddle.

Using the adaptor the card should cope with the 3 small fans without messing around with voltage reducers.

Hey just to close the thread. The cooler connects by default to molex and has a 7v and 12v plug for fans. I got another cable made and it now works I can set fan curves and hear the RPM changes.

I still puzzled why it didnt work on previous adaptor when I reattach it.

Thank you for taking time to reply.
