CPU too hot. Which heatsink to get?

[Flopboyz]

On this computer that I am typing on right now I am running a Intel 2.8 Ghz. After installing Everest Home Edition I get the following readings:

Motherboard Temp: 25 Celcius
CPU: 33 Celcius
GPU: 59 Celcius - ATI Radeon Pro 128

On my other computer I am running an Intel 3.0 Ghz. Readings are

Motherboard temp: 43 Celcius
CPU: 54 Celcius.

Both systems are idle right now. Does the GPU temperature seem a bit high in the first machine? If so, what heatsink would you recommend?

The CPU temperature in the 2nd machine is a bit too high for my liking compared to the first machine (which seems fine and maxes at 40 Celcius when there's a load on the cpu) and when there is a load on the 2nd cpu, temperatures can go up to 65 to 70 Celcius which is pushing it to the limit.

I use the standard Intel heatsinks that came with both cpus, but don't understand why the 2nd cpu is running so much hotter.

I am thinking I may need to change the heatsink/fan on the 2nd cpu, but I don't have much space as my case is small. I checked out the Zalman 7000 series heatsinks, but they are too big.

Does anyone have any recommendations for a smaller heatsink that will work well?

Thanks

Something big and copper. I.E. Thermaltake Silent Boost.

Hrm, that doesn't sound as good as BFG or BFK. 🙁

see if the thermaltake xp-90 will fit.

I just replaced the standard Intel heatsink on a 3.0 GHZ P4 (socket 478) with the Thermalright XP-90 and the Enermax 9FAB fan. The change dropped the under load temps by about 8 degrees C. Based on all the reviews of the heatsink I expected closer to 15 degree C drop. Under load the temps with the stock heatsink and fan were around 67 degrees C and now they're around 59 degrees C. The full tower case interior temp runs at about 33 degrees C. I think this is a little high and probably from the ATi AIW 9800Pro. The case has 3 Enermax 80mm UC-001B-TC fans not including the power supply fans or card fans. Room temp is about 21 degrees C.

The mating surface on the Intel heatsink was copper plating and the surface on the XP-90 was nickel plating. The base of the XP90 is suppose to be copper with a nickel plating. Other than for looks why would anyone want to plate the copper on a heatsink with nickel?

I used the stock thermal paste/pad on the Intel heatsink and Arctic Silver 5 on the XP-90.
