LRWW vs. TDX

Orkan · 01-25-2005, 01:49 PM

I am going to be building an A64 system. I currently have a whitewater running on my AthlonXP. The integrated heat spreader on the A64's has me wondering if the whitewater will perform as well as a TDX.

Probably the same if not better.

Not to mention the LRWW outperforms the DTWW slightly because of the better build quality and flatness of the base.

Was the testing of the Dtek WhiteWater and TDX blocks on the above chart done on an Athlon64 with integrated heat spreader?

That is really my only concern. I know that the WW performs excellent while sitting directly on a die. The area that it is cooling is close to the same width as the channel. With the IHS found on A64's, that is not true.

Looking at it from that perspective, the TDX would seem a better choice as it has moving water over nearly the entire IHS.

If it matters, It will be in a loop with a Maze4 GPU cooler, a 2 bay bayres, and a Thermochill 120.3 rad.

Anyone have test results of a WW vs. a TDX on an A64 system?

Take off your spreader. Since you are not using the stock retention system it should not be a problem.
Temp improvements up to 7C have been reported under load.

if you are concerned about the fact that it has a heat spreader...all a heatspreader does is increase thermal resistance and possibly increase your chances of a more uniform mount

it would affect the cooling performance of the ww and tdx equally, particularly because their cooling bases are both similarly more concentrated than the norm

And it decreases your chance of cracking the core.

Sounds like my Sempron needs to get cracked open. Maybe then I'll break 2.6Ghz.

A heatspreader doesn't change the size of the die, so it shouldn't favor one block over another since the size of the heatsource is still the same. In effect its just like giving each block a slightly thicker base and a higher TIM resistance.

From what I've seen people who remove the heatspreader don't normally get more than a 50-80MHz boost.

Don't think I'll be taking mine off.

I'm still wondering if anyone has any test data of a TDX vs WW on an A64...?
