Clover C3 Latency Issue?

I posted this as part of the Clover general discussion, But I think it might get lost over there so I'm posting here also.

 

I'm having an issue with C3 Latency settings on an older Bloomfield CPU (i7 950). I set the C3 Latency setting in the Clover config.plist to 0x3E8 and speed step started working, which at first was great. Unfortunately my CPU temps started rising, all cores running over 90. I then tried 0x3E9 (speed step off) and also tried just deleting all the SSDT settings in the Clover config.plist, but speed step is still on and my CPU is still running super hot. I also tried 0x00FA, didn't help the situation.

 

Prior to this I was getting simply the 12x and 24x multipliers for the CPU speed and temps around 60.

 

Beyond those settings I'm not sure how to switch it back off. I blew out the EFI partition and reinstalled Clover, the same problem persists. I'm now starting to think that something got "turned on" in El Capitan and is not getting switched back off by changing the Clover config back.

 

​I also dumped and rebuilt the kext caches, no luck.

 

Just to make sure it's not a fan / cpu cooler problem, I plugged my old drive back in with Chameleon installed and the CPU temps are back to normal.
