Accelero wrong rpm reading ?

[Soulkeeper]

Anyone else experience erratic rpm readings after putting an Accelero twin turbo II on (or any cooler) ?
Just going by ear changing the fan speed via software seems to work, but the rpm readings are insane ie: 1-50,000+ rpm

I'm just wondering if this is a common problem.

Yes, I've had this issue, I've just ignored it. I'm using the 7970 Accelero Extreme and I assumed because it's 3 fans, and not PWM.

I think the highest mine spiked was like 79,999 RPMs haha.
