The "Undervolting" Guide

Your 30 min. stress temps say 73 and 71 for Cores 0, 1.

Am I reading your CPUID wrong ?

oh, that was after I'd stopped the stress test, you need to look at the max temps of 95/96 which it reached during the stress test

I believe CPUID saves a log file of the highest and lowest readings you've ever recorded. That means it will recall data from before undervolting. The min/max values are not important. What are your core temps during testing?

All temp values were reset before the stress test. So the min of 42/44 is at the start of the test and during the test the core temps just get higher and higher. They reached 96/95 at which point I stopped testing

Just for fun, show us the RMC temp graphs during Orthos.

k, just ran Orthos, after 5 minutes it was 85 degress, this is how it looks after only 8 minutes. I don't want to run it too long anymore as this could be doing more damage than it's worth.

Pretty clear that the problem is your fan or heatsink.

The thing is, the laptop is only a few months old and it doesn't *feel* hot when being used, not compared to my old laptop. And if it were purely a problem with the fan or heatsink that wouldn't explain why undervolting has no effect.

Depending on the environment(s) that the laptop operates in, a couple of months can plug up a heatsink and coat the blades of the fan with a thick layer of dust. If your heatsink/fan are really dirty, undervolting will have no effect, as the cooling system can not dissipate more heat than is generated at idle.
If it was me, I would take it apart and clean it, then undervolt.

k, tomorrow morning I'll take it apart and have a look. Thanks for the help thus far guys

Best that you mind Mklym or he'll arrange to have Newfoundland returned to you Brits C.O.D.

Actually, computer parts seen to always fail straight off or else never, right?

If your heat transfer mechanism is broken, the components get hot but the case remains cold, right?

Lowering the voltage on a CPU simply makes it heat up a little slower but if not conducted away still continues to build up.

You'll find it.
