Quick heatsink help

[tomyhill598]

I just recieved my Thermalright SLK-497U heatsink, and I realized it is a good bit smaller than the stock heatsink I have for my P4 3.0 GHz. I thought the more surface area, the better the heat will dissipate, but then again this heatsink is completely copper, so I dont know if I should use the SLK-947U, or the stock heatsink. Thanks for any help.

I forgot I had one more question...I am installing a Thermaltake Smart Case Fan 2 on the heatsink, and would you normally put the temperature sensor for the fan on the heatsink, or between the cpu and the heatsink? Thanks again.

Bigger heatsink doesn't necessarily mean better cooling.
Design, material, and largeness are all factors.

Copper catches heat quickly, but its shy to let it go.
Aluminum doesn't catch heat as quickly but throws it away easily.

The best is probably a combination of Copper and Aluminum.

Copper Core and Aluminum Fins are probably the better choice.

But I think the 947U, which is what I'm using right now is the better one. But you should just test it out for yourself and see. Install one heatsink and Leave it alone for about a day and then download sisandra and run some burn in tests and record the max temp and repeat with the other one to see which one is better.

put it between the HSF and CPU, closer to the cpu the more accurate
