Not very familiar with PCs, however having been working with electronics for
quite some years, I would say (guess) the temperature sensing of your PC is
ok, based on your observation that it works over a range from 80 degrees down
to 50, which is assumed to be a "working range".

Cooling of electonic devices in general is however an interesting animal.
First part of it is proper given requirements and following design performed
by the manufacturer.

Secondly are the environmental aspects of significance, with respect to
space and temperature. Some kinds of fans may stall i.e. reduce capacity,
sometimes by a great amount, when ducts / airflows are changed with respect
to original design. I assume the “- large fan at the back -” of your PC is a
kind of tubeaxial, which wouldn’t stall, however is it important that there
is some free space behind the outlet to allow maximum airflow. “- taking all
the sides off the case –“ may not be a good idea, presuming that cooling of
your PC was well designed, in accordance with the manufacturer requirements.
I also assume that there has been made no hardware changes to the PC, which
possibly could have made the two fans to point the airflows towards each
other.

Thirdly is it important the the PC is working within environmental
temperatures, as specified by the manufaturer. The tower of my PC is situated
in a separate space of a PC furniture, which is not really smart, as it
accumulates the “local” environmental temperatures a lot on warm days.

Hi, Thanks for that.. I have now (touch wood) fixed the heat issue.. idle at
40 degrees celcius full load bearly reaches 60 degrees, it probably wouldnt
get that high if my lazy cpu fan got of its arse, it still sits at 3100 rpm,
when the temprature is at 60 degrees even with my settings set for it to run
at full speed? anyway I can live with that.. however that did not solve my
issue.. I've had 3 more random BSOD's all starting 0x000000 then one ending
in E7 another 24 and lastly A .. and since then I tested my ram again.. as i
had tested it before with windiag at normal settings which runs 6 tests.. but
this time I set it to run extended test and this time it found errors, after
3 passes it found 54 seperate errors, but still passed most of the tests? on
the previous test as it passed the first 3 tests I assumed it was ok and
ended it early.. this time it still passed those tests but after the 6th test
it started to fail a few.. So if anyone reading this has had similar
problems, I urge you to you windiag, windows free memory tester, and let it
run for a minimum of 3 passes on extended tests, you'll know what I mean when
you get it up and running.

With regards to the heat issue, I now have one large and two small fans on
the side of my case, which had a perspex window in it, which made cutting the
holes for the fans easier :).. they are blowing air against my motherboard
and obviously also my CPU and the large fan at the back is drawing air out..

I know have an old RAM stick in, and as of yet have had no BSOD's.. it seems
crazy to me how all these differently coded error messages could have been
the result of a RAM stick gone bad? Windows should really have been able to
diagnose this, and report the error correctly. I will post again in a few
days if all is well, which would mean it was definately the RAM, if not you
will hear from me soon :( Thanks to all those that gave me advice :)
