memory heatspreaders...

[poMONKey]

2 things.... do they really do anything but prevent proper airflow and can they be removed from a stick???

thanks >>>

Prefer proper air flow?? How is that? The spread is stick on the chips via epoxy so if there's any air flow, it should be between the sticks and not below the speader. If that answers your question.

Secondly, I don't think heatspreader will do much except for maybe 5-10Mhz extra.

more like airflow around the chips on the memory... not airflow in the case >>>

seems like the heatspreaders would keep more heat in and around the memory than it dissipates...

but what do I know????

The heat of the chips would be transferred to the spreaders which will then dissipate the heat to the surrounding. The chips are usually not hot enough to burn. They're often warm to touch and a heat spreader is more than enough to cool it. The surface that the spreaders provide will be more than enough for the heat to occupy.

The reason heat spreaders work is 2 main reasons... first off memory doesnt get very hot in the first place.... and 2nd because all chips produce more heat in some spots then others... so since there isnt a whole lot of heat in the first place, the spreader spreads the heat across everything which allows for better heat disappation and also lowers overall tempurature of the chips.... instead of the hottest spots on the chip staying hot... the heat is spread around. Heat Spreaders are good. Your heats mostly being transfered into the heat spreader... and most heat spreaders are aluminum, and aluminum dissapates heat into the air alot more efficently then the chips themselves do.
