Re: Apogee/Storm
To clarify.
I quite like budwise’s explanation, idiotic maybe but shooting for the lowest common denominator is often not a bad thing.
An apogee is a worse performing block than a storm however its worse performance is masked sufficiently by using a heat spreader. As a heat spreader is like a warm jacket keeping your processor toasty warm (relatively). For practical purposes it means that an apogee will give near equal die temps (the whole point after) as a storm with an I h s but this is not because it is good but because your I h s is bad.
The electrical analogy is often used for students to clarify thermal resistances. Think as an I h s, waterblocks and layers of thermal paste as an electrical resistor. The storm has a much lower electrical resistance than the apogee and the I h s has a big electrical resistance overall.
The electrical / thermal path looks like this:
I h s
Cpu electrical source – thermal paste – I h s – thermal paste – WB – rad - ground (watercooling rig)
No I h s
Cpu electrical source – thermal paste – wb – ground (watercooling rig)
If the I h s has a really big thermal resistance then it does not mater how good your wb / rad is because the overall resistance will be about the same like putting a 1 kilo ohm resistor in series with a 2 or 5 ohm resistor. You won’t notice if it’s a 2 or 5 ohm resistor as the 1 kilo ohm resistor is in the way.
