The heatsink that comes with the retail Intel processor is certainly 
adequate for running your CPU without fear of burning it up, unless you 
intend to overclock (and overvolt) the processor.

The next step up, from the Intel stock setup, might be to the Arctic Cooling 
Freezer 7 Pro.  This heatsink and fan is modestly priced, but performs quite 
well.  If your primary goal is to have a quieter running system, this would 
be a good choice.  See link below.

If you're interest is in maximum cooling in order to support an overclocked 
quad core processor, you'll probably want to look at the high-end 
Thermalright heatsinks, such as their Ultra 120 Extreme.  See link below. 
Check the dimensions of these 120mm fan heatsinks, carefully, since they are 
quite tall, and unless your case is wide enough, they won't fit.

As to your power supply choice, without knowing which video card or cards 
you intend to run, it is difficult to say for sure what you need.  The 650w 
Antec P/S you mentioned should be enough for a single video card.

Subject: Heat sink & cooling fan

Greetings,

I am building a new computer and have an SLI Motherboard, XFX nForce 680i=
 LT, I have a Core2 Quad 2.4 Hz cpu and want to get a really good heat si=
nk and cooling fan. What would you recommend? I prefer it to be quit, but=
 am more concerned about the effectiveness, don't want to burn out the cp=
u.=20

Also looking at power supplies, will the heat sink and fan make a differe=
nce? Everything I have read points to whether or I will be using two grap=
hics cards. At this time i will not be, but maybe in a year I will. I am =
currently planning on getting the Truepower Trio, 650 Watt, ATX12 v22 & E=
PS12v.

Thanks for any ideas.

Mike Fitz
