Dont worry Ben, the tc reader was there just for the picture.
The problem is that no matter how steady is room temp, outlet is going to be always over it. So by just walking arround in the room air circulation is altered and readings change.
In a tipical heatsink inteke and exhaust are so close together that theres alot of recirculation. I have the idea of ducting intake from a more steady area, but my concern is "ethical". When doing that I'm creating more ideal conditions for the heatsink than the tipical use. At how point isolating distracting variables become improving product flaws?
One of my initial ideas was testing things as delivered; that means using the included paste and sopport system, but this proved to be a big problem for tests:
1- Thermal pastes are the source of nightmares! each one has different set up time, and is not very practical waiting 48 hours after each mount to start testing.
2- Included supports can be dangerous! It is a good idea being able to report possible mounting issues, but discovering them in the test hardware can kill it! While mounting Thermalright SP7, one of the supports cracked an SMD resistor on my Epox 8RDA mobo that was too close to the hole.
