775/1155 cooler heat dissipation

Hi,
Slightly different take on the 775/1155 question - I'm comfortable with the physical compatibility but:
I've got an old 775 from a P4 with a TDP of 115W. Given that my new CPU (i5 3rd Gen ) has a TDP of 77W, does that imply that that there is greater cooling capacity & that it would be a good bet for my new setup? I'm not doing any radical gaming (nothing more than occasional Minecraft) or overclocking, although this will; be a work PC running GIS software (biggish computations) & Photoshop.

The cooler is actually from a Dell Dimension 8200, with heat pipes. I know Dell, er have their niche, but this is pure physics surely? And it will be reasonably well made.

I can get a stock cooler for not much so it's not about the money, just that it might potentially be better.

Your thoughts would be appreciated.

  1. Best answer
    Well if that cooler kept a 115w cool it certainly better for the 77w @ stock clock
    if you overclock than it might not anymore.
    Heat pipe cooling is best air cooler
    Question is will the 775 fit in 1155? if it does great
  2. 775 and 1155 aren't compatible (1155 is slightly larger) but if you're cooler is certified 1156 it's ok for 1155 and upcoming 1150 "Haswell"
    (i can proove as i myself tried to do this)

    77w is the max stock tdp so your cooler will do just fine and a lot better than the intel one but once you'll start to overclock (if a day you want to), make sure it's a good cooler cause Sandy and Ivy heats a lot when going at higher frequency and voltage (Ivy is hotter than Sandy too)

    There are mixed messages out there on the interweb - like you, some say it can't be done. Others say they've done it (albeit with a small bit of judicious filing). Maybe id depends on the actual cooler.
    My motherboard should turn up shortly so I can investigate. Will only set me back a couple of days if I can't. Patience & all that.
    Reassuring though to know that my thinking is correct though & that there are no arcane mysteries involved.
