I purchased a computer a month or two ago (core i7, 24gb ram, geforce gtx 590, windows 7 ultimate). Within the last week it began to bluescreen regularly. I tried lots of things (check hds, check memory, reinstall windows etc..) but it still bluescreened. At the time my temps were as follows...

CPU - aprox 40/50c. GPU - arpox 60 idle, aprox 90 during heavy use. HDDs - aprox 55c after the PC had been on a while.

I thought the 55c was ok, but I have since realized it was probably too high and may have been the direct cause of the bluescreening.

I've installed a spare fan I had in the front of the PC blowing air in, (so there's airflow from front to back)

Since then, obviously, all my temps are down. Especially the HDDs - three of them reach 30c and one has been up to 47c (it is some distance away from the airflow, in one of the 5.25inch drive bays)

I haven't had the PC on for as long as it would normally take to bluescreen yet, but If it does I want to know what all the temps were right before the bluescreen. I have tried Everest but it only shows me realtime temps or gives me the ability to create one-off reports.

I want something that can record all the temps to a file at 30 seconds intervals. If the computer bluescreens I can load it up again and check the last entry in the file.

Side question: Am I right in thinking 55c was far too hot for a HDD? (It might have got higher than that before the bluescreens.. I don't know)

Another side question: Is 47c too high? This is actually why I am asking the main question - I am concerned that this one drive that isn't getting the benefit of the extra fan may still cause the computer to bluescreen.
