I have a GTX 570 and it doesn't downclock when idle anymore. I thought this was due to adding a second monitor, but when I disable my extra monitor the issue is still there. My power settings in the nvidia control panel are set to adaptive, and as I mentioned earlier, it was working when I got the card.

Other specs for my system include:
AMD Phenom II 1100XT
8GB DDR 3 RAM
ASUS M4A88T-V Evo/USB3
Geforce GTX 570
Corsair 650W
2 HDDs, one 640GB and the other 500GB

I have the latest Nvidia driver as well, maybe I should try  one of the betas?
EDIT: Actually it does downclock without the second monitor. So it doesn't downclock with dual monitors. Are there any known fixes or workarounds for this?

PowerPlay saves power via engine voltage, engine clock, and memory clock switching. Memory clock switching is timed to be done within an  VBLANK so that a flash isn't seen on the screen when the memory speed is changed. This can be done on a single display, but not with multiple displays because they can (and in 99% of the cases, will be) running different timings and virtually impossible to hit a VBLANK on both at the same time on all the panels connected (and when we say "timings" it’s not as simple as just the refresh rate of the panel, but the exact timings that the panel's receivers are running). So, to keep away from the end user seeing flashing all the time, the MCLK is kept at the high MCLK rate at all times.
With regard to power savings under multiple monitors, we have to trade-off between usability and power. Because we can't control what combinations of panels are connected to a desktop system we have to choose usability. Other power saving features are still active (such as clock gating, etc.) so you are still saving more power than peak activities. Note, that in a DisplayPort environment we have more control over the timing and hence this issue could go away if all the panels connected were DP."
