heatsink CPU temperature troubleshooting techniques

1. The heatsink was cleaned with an oil based cleaner which filled the microscopic gaps and contaminated the interface. 

2. The existing thermal interface material was not completely removed. The compound should be the only material between the heatsink and the CPU. 

3. The heatsink was not installed properly. 

4. The thermal compound was applied too thick. 

5. The measurement is being taken on the cold side of the thermal junction or on the side of the core where thermal compound squeezed from the junction contaminates the probe. (Better compound then transfers more heat to the probe so the temperature reads higher.) 

6. The measurement probe moved when the chip was removed to clean off the previous compound. 

7. The compound was not allowed to go through its break-in period. (Minimum 25 hours. Can be 400+ hours.) Temperatures will drop 1C to 5C over this time. 

8. The application was contaminated with an eyelash, a bit of dirt, fingerprint or something else that spaced the heatsink away from the metal cap. 

9. An unbalanced heatsink fan is causing excessive vibration and damaging the interface layer. 
10. An improperly manufactured or bent shim is interfering with proper contact between the CPU core and the heatsink. 

11. The heatsink fan was not plugged back in after the compound was changed. 

12. The ambient temperature where the computer is located has changed. If the room temperature changes, the CPU temperature will also change. It is important to remember that cooling solutions keep the CPU X number of degrees above ambient. So if the ambient temperature increases 3 degrees, the CPU temperature will also increase 3 degrees.

some real coast to coast with george noory here

I sense a lack of one, big, crucial element here: breathing. 

Controlled breathing is a fundamental item for this kind of things, as it slows down heart rate,, regulates oxygen levels in your blood and relaxes your body, not in the "ooooh, i'm so relaxed right now" way, in the "I'm letting my body go for a while" way. 

Learning to breathe the right way educates your body to recognize wether you (and by "you" i'm talking about your inner consciousness, the one that inhabits your physical body) are just doing your daily stuff or sleeping, or meditating. Try this for a 20-30 days period, straight: when you go to sleep, lay on your back, your hands by your sides or on your legs. 

Close your eyes, and focus on the glittering black curtain behind your eyelids, knowing it is a thin layer of skin just a few centimeters away from your retina: concentrate and perceive this physical distance. In the meanwhile, empty your head from ANY (repeat: ANY) thoughts, wether they're verbal ones (your own voice commenting your actions or what's happening to/around you) or just feelings/sensations. 

Once you're set like that, start a breathing cycle, this way: 6 seconds in-breathing, 3 seconds hold, 6 seconds exhale, 3 to 5 seconds hold (empty lungs). Try to make this as natural as possible, not forcing nor contracting any muscle, thus using your diafram and latting the air reach the bottom of your chest - feel your belly as it inflates, don't breathe with your upper chest. Imagine your lungs as a tank, being filled with a liquid: it starts from the bottom and then comes up as it fills up. 

Don't count rationally - keep this process as instinctive as possible, and give yourself and your body time to learn this. We all breathe the wrong way, filling and emptying our upper chest too quickly. That should help setting up a friendly environment for every kind of meditations and OOBEs.
