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?

  1. 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.
  2. 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.
  5. The HSF i am replacing is the same as the one in the pic you have shown of your rig.
    The one i am replaced it with is http://www.frostytech.com/articleview.cfm?articleid=2025&page=2 .

    And since now i have already replaced it, well i am getting same temps at 3.2ghz what i got on 2.66ghz with aluminium.
  6. 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?
  7. Yeah, was there in the hardware pile for my last computer.
