Processor Temp

[poorguy]

Hey All,

OK I replaced a 35 watt Celeron processor with a 65 watt Core 2 Duo E6300 1.8 GHz processor both LGA 775.
Processor temps never exceed 75 degrees Celsius and max Core 2 Duo temp is 61.4 degrees Celsius.

All aluminum factory heat sink was reused and at physical touching by hand heat sink is barely warm to touch at base of heat sink.

I found an OEM Dell heat sink that has a copper base plate with tubes through steel or aluminum cooling fins.
My question will I gain any improvement by replacing the all aluminum heat sink with the copper base heat sink.

Computer is working great without any random stalling or shutdowns.

What would you do.

These are the Dell OEM heat sinks.

Hello!

There is so much dispute about this issue that I don't even bother any longer.

Copper has a higher thermal conductivity and so pulls heat out of the processor more quickly. However, it can become become saturated because it is not so good at radiating the heat into the air due to its density. Aluminum, on the other hand, is less thermally conductive, but transfers heat to the air better because of its lower density.

As a consequence, many of the more expensive air cooling HSFs have a copper base with their heat pipes soldered to aluminum fins.

What I do is find reviews of each of the coolers (sometimes they are listed together so you can compare easily) and make my decision based on cost/effectiveness. Some coolers are poorly designed, others well designed -- despite the metal.

So I suggest doing research rather than trying to make a generalization.

Cheers.

Hey Qlll,

Good Point and do understand about the thermal conduction and heat dissipation.

Been salvaging old desktops and and discovered all the cool parts etc so the gray cells in the brain started moving around and here I am wondering.

Thanks

Hey Qlll,

After some reading I discovered the temps I'm seeing are the Core Temps and always higher than case temps so I'm leaving it as it is.

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +67.0°C (high = +84.0°C, crit = +100.0°C)
Core 1: +62.0°C (high = +84.0°C, crit = +100.0°C)

Thanks 8-)
