High Temperature Concerns

[OCC]

Just built my i3770k system (with Coolermaster 212 EVO) on an Asus P8Z77 board.

Now, so far all I have done is run the auto-overclocking functionality available via the Asus software and it has got me up to 4.4Ghz.

During normal usuage the recorded tempearatures are in the 30-40 C range. However, I started to run an AIDA64 Extreme stress test and within 5 minutes one of the cores hit 97 C, with Real Temp reporting a LOG. The other 3 cores didn't appear to get as warm, max of about 90 C.

I am slightly concerned how hot one particular core got after only 5 minutes of stress testing. And when I saw it go so high I killed the stress test immediately.

Am I over-reacting? Any thoughts?

If it's in Auto for Vcore it'll be giving it something daft like 1.4V.

I checked and it was giving it round about that.

Re-ran / made some changes and now at 4.2Ghz using only 1.3v max and all cores remaining around 70 C until full prolonged load.

Still slightly concerned that cooler fan never seems to really kick in and wasn't flat even when I was getting temperatures in the 90's. Now, even when core temps are reaching 70 C, the fan is only running at 600 rpm (when it has a max of 1800).

I let Asus Fan Xpert 2 software auto tune it. I guess I should be changing it (in the bios? or other fan controller software?) to be more aggressive when temperatures rise?
