Fans & Camshaft Deviation QUestions

[AKnowles]

After getting my drivers side tire patched today - I found a nail in it while filling it up with gas - I decided to check out the car with my handy dandy PST2 for other prevative maintenance. While I was there I noticed two potential oddities:

Fans: I was checking the fans and fan 1 runs at half speed during the test, but fan 2 runs at full speed. Does this mean the resister on fan 2 is bad? Assuming both fans should run at the same lower speed (based on prior searches).

Camshaft Deviation: At idle both hold a rock steady ready, but cam 1 is at 0 and cam 2 is -6. From what I have been able to determine (yep, more searching) it is within specifications. But the question I have is ... is the -6 a camshaft timing issue that I can adjust using the DIY camshaft timing (which is what I am thinking) or is it an issue between the two cams (intake/exhaust) and needs to be adjusted by removing the valve cover?

Of course, the other question would be ... should I even bother and if I do should I take it to a Porsche shop to do it?

Any feedback apprecaited. This one is out of my normal comfort zone for determing the cause/issue as I'm just not that familair with the tools and motor yet.
