CPU and GPU fans reversed on m17x R4

Okay, so a few months ago I installed a 8970m card in my system. It runs well, but the fans stopped working after I installed it, so I've been using HWiNFO to control them.

Well, I've been having CPU stuttering ever since. The problem's gotten worse lately, and I'm thinking that either HWiNFO is the culprit, or it has something to do with whatever caused the fan problems. I upgraded to A13 bios just prior to the upgrade.

So I booted into the system diagnostic tool today to try and get to the root cause of the issue. The "CPU Fan" test flexes the CPU fan and the "GPU Fan" test flexes the GPU fan properly. This was the case when I first ran the diagnostic after upgrading the GPU. Since those tests ran fine, I missed the reversal, and assumed that the operating system was having trouble spinning up the fan entirely. This time, though, I noticed that during "CPU Stress Test" the GPU fan begun to spin up faster and faster. It also happens to be the case that the GPU fan is the only one spinning at boot, before I load up HWiNFO.

I've been testing, tweaking, checking my system and babysitting HWiNFO for months. Please help me. I'm at wit's end, but I think that just maybe, if I can solve the fan reversal, then my system will work as it should again without CPU stutter or the need for HWiNFO.

EDIT: It occurs to me that the problem might not be a total reversal, as I cannot prove that the CPU fan would spin up in a case when the GPU fan ought to. It's hard to keep the system up for long without HWiNFO because it will just cut off abruptly. (THERMTRIP, I think.)

 

All I can add is that is very weird.

When I tried out hwinfo (an unsupported GPU messes with the fan control firmware) both fans operated as one. I had a table set on the GPU temp so if for some reason the CPU got hot when the GPU was at idle, the fan would not crank up .

I asked around and was told that one of the drawbacks with HWInfo fan control is loosing individual component control.

 

I've found a temp/fan control table that works for me, and I've tweaked HWiNFO to have as little impact on system performance as possible. It's also important to disable all extraneous monitoring for performance/stability reasons, as I've learned through months of trial-and-error.

I just wish I could take the program out of the equation entirely. At least the new catalyst drivers have solved a lot of the stuttering for me. It must have been GPU stutter I had mistaken for CPU stutter. An easy mistake to make, as HWiNFO has caused me CPU stuttering in the past. That was an agonizing month.
