Intel HSF Copper vs Aluminium

I just want to know if the Intel Stock heatsink (Copper base and a bigger heatsink(in height)) that came with a Pentium D, be more effective in cooling than the Stock heatsink with Aluminium base and a 1inch heatsink which came with my C2D?

IMO the copper would be better, but how much would be the difference?

Also, while i am at it, is the difference between a 1$ cheap thermal paste and a 10$ exotic one too profound? Do you really need to get a 'good' thermal paste?

I would say the Pentium D heatsink would be better. A copper base with Aluminum fins is ideal because copper has a higher thermal conductivity than aluminum, and aluminum dissipates heat faster than copper. As far as thermal paste goes, it depends what you are doing. A cheap paste will be fine if you are running at stock speeds, but if you are looking to overclock as far as you can then a better paste will make a difference. I went from a cheap paste to an expensive one and it dropped my load temps on my i3@4.0 about 7 degrees. On the other hand, it will make more of a difference when using a good aftermarket cooler, and I'm sure there are cheap pastes out there that do a fine job. It just depends what you are looking at.

This page will settle the what material is best argument:

Of course, material is only one part of the equation. The best coolers are identified here:

The copper core heatsink will work better for sure.

It was designed to dissipate more heat(Pentium D). If you have one, use it for sure. I bolted a E6600(copper core) heatsink to my 1156 board with good results(must quieter now). I wish i never gave away my Q6600 stock heatsink now....

Can you give me an idea of how much is the difference?

Either way, i think i'd replace my tiny C2D HSF with the bulky PentiumD one.

It will depend on the amount of heat the cpu produces.

In my case i got a good 10+ degrees cooler. And to add to this it was much quieter. I want only after quieter.

Your results will vary, but either way, it should be better.

According to frosty tech, the PD heatsink will be about 9 degrees cooler then the core2 duo(the first one so not the low profile one) at 150 watt load and 5 degrees 95 watts.

Is this your heat sink or is it the slimmer one? If its this about 5 degrees and 6db louder. the Pentium D heatsinks shine at higher heat outputs. if your cpu came with this, its not a high heat output one.

here is what i replaced. as you can see it was very small. Was almost sure I had an after picture, but guess not.

As i said before. I wish I never gave my Core2 Quad(Q6600) heatsink away. Ohh well.

Glad to hear you got good temps like I did.

My heatsink was a little different in the fact that it had a copper core and is a 1156 one(thus my bolting).

Where did you get the PD cooler? just have it laying around?

Yeah, was there in the hardware pile for my last computer.
