That is so interesting Tom,
I had wondered whether most of this attention to make and model would be mostly hype. I currently have an all ally evercool ND15-715CA it has a 70mm fan controlled by bios. I think the airflow seems good. No reason to think it is getting trapped.
The only thing about this heatsink that has me questioning it is the power of the retention spring clip itself. Compared to other makes and models I've fitted before, the retention clips are too easy to fit to the cpu. No, I hear you say, so what. Well the heatsink , if you notice carefully, sits in situe on 4 small rubber grommits about 3mm each in diameter.So the heatsink has to be held really firmly against them to make the heatsink BED down flush onto the cpu. If insufficient pressure is exerted by the retention clip there might be a possibility of the heatsink not fitting flush onto the cpu. I know, the heatsink paste ought to take care of it but maybe not enough ? It's only a thought.
I already have both the case sides off , don't make much difference though, about -1C is all I get overall on the case temperature. Case airflow is in at the front low down under the harddrives and out either through the PSU, or a vent in the rear of the case undet the PSU. Entirely conventional in layout. I have no means of removing the top. I don't know what else I can do without getting surgical . The computer sits on my bench beside me which means about as good a spot as I will get for general room airflow.
So what I'm reading from your experience seems to suggest I ought to be getting better general temperatures than I am getting, but with the one possiblity of the strength of the retention clips , I cannot see what I'm doing differently from you and yet I would feel more comfortable if my cpu temps were held well withing the 40 to 48 range under all load conditions. Hmm.

I agree with what Tom is saying. But a CPU that isn't overvolted or overclocked should be OK at an idle temperature of 48C. I would still suspect a PSU issue. Its worth checking by borrowing someone else's just to rule this out. Modern PC components draw massive amounts of current in surges. If your PSU lets the voltage drop slightly too much when this happens (ie not matching the ATX standard of -+5% tolerance) then you get system instability.
Just my $0.02.

Could I set up a test rig to record power surges in overload use, or something.
to hell if it surges and siezes up. as long as I've some stats to analise and present a case, if only to myself.
gkrellm does running voltages, but I find reading them near impossible.
Sensors does one time reports I can read, but not running voltages.
I don't mind condeming equipement, but I don't like, condeming without reason.
I've got spare PSU's that's no problem, but what is there to say the replacement is not just as bad ?
