New Thermalright heatsink with heatpipes

overclockers.com has a look at Thermalright's latest P4 heatsink, they've added heatsinks and the test results certainly look impressive.

Here's their Zalman 7000cu review for comparison (In both reviews, note the tables examining fan rpm rates and resulting cooling abilities)

looks interesting.. I hope the prices of the older heatsinks drop..

Hmmm, I wonder how much good a heatpipe does when it is only moving the heat an inch from the original location? Yes, that's a rhetorical question.

My opin is that these so-called heatpipe-heatsinks are nothing but sales gimmicks. An engineer would not be proud to have designed this thing. There no advantage in having a heatpipe unless you're moving the heat at least several inches -- like the heatpipe / heatsinks in the Shuttle SFF PCs.

What about something that runs a heat pipe off the CPU to a radiator like mesh attached to the back of the case?

That's what the Shuttle SFF PC heatsinsk/pipe is. They seem worthwhile & have a real purpose.

Sorry Mike, I do agree that the heatpipes wouldn't do a lot to improve performance, but I *would* expect a small incremental benefit. And considering that people are willing to pay premiums for SLK900's / SLK-800's over an SK-7, I think the market is willing to accept incremental cooling benefits.

Anyway, the only data set that gives any insight right now is a comparison of overclocker's SLK800U review vs the SP-94 heatpipe one:

800U: http://www.overclockers.com/articles726/
SP-94: http://www.overclockers.com/articles798/

the comparisons matching up fans at similar rpm's paints the heatpipes in a favorable light. The fan models are different so it's not a great comparison but it's the only test data we have so far

didn't someone make a heatsink already with a heatpipe just like that? I want to say thermaltake, about a year ago?

Edit: Got it, Coolermaster HHC-001.

Coolermaster made the HHC-L71and IHC-L71.

Point taken. It's true the 900 is only marginally better than the 800 & half the 800 owners around here seemd to snap it up.

I'll see if they'll send me one to test -- SPCR style.
