Asetek's Extreme CPU Cooler Tested

VL writes "Do-It-Yourself Phase Change Cooling Systems are built and used by a few folks, but they can be complicated to build, mostly messy, and dangerous; certainly not something you should get into without knowing what you are doing. But as with anything like this, there is always a turn key solution brought to market you can buy. Enter asetek, and their VapoChill series of Phase Change Cooling systems. What we have on the review bench here specifically is the asetek VapoChill Lightspeed [AC], a case separate enclosure containing a Phase Change Cooling system for your PC's CPU."

      It's a P4. Remember they slow their clock down if the chip gets too hot. Encoding software fills the pipeline pretty well, that's why the P4 does so well at it. So the chip used a lot of power. My guess is that stock cooling just isn't good enough on high-clockspeed P4's.

      Redo this on a slower P4 or an athlon{XP,64} and I don't think that you will see a difference. That said, if they did not do several trials of this test ..... 0.5% difference is likely less than the margin of error.

      OK, most of what you said is both true and insightful, which is why I bought the heater core for a car, the aquarium pump and scientific tubing instead of the Xtreme stuff most sites sell. The one mistake you made was the waterblock remark.

      Yes, it is only 50 cents worth of copper, but you kind of need that thing that mills it out. I certainly don't have anything here in my toolbox that can mill out a piece of copper. I also don't have ready access to a machine shop that would be willing to do it for me. They also have been making the designs better from an iterative process (not a scientific one), so I'd have to take the time to find a good design (and make sure it doesn't leak when I put it together). The waterblock is the one thing I couldn't do by myself when watercooling, and I really did research to see if I could. So I don't think $40 is too much to pay for a piece of milled copper if it is something I couldn't do by myself without hours and hours of work for a probably bad result.

      IMO bigger/better fans are just good for fighting the symptoms. We are just heading the wrong way - instead of integrating mobile technology into desktop computers we basically invest the same money into designs which can dissipate more heat.

      I think it wouldn't really be much more expensive to produce CPUs with a low TDP (if they are produced on a big scale) and I definitely believe that it would be cheaper in the long run, because those fans and heatsinks etc. wouldn't be necessary anymore.

      I really hope the manufacturers are going to realize this soon. The fact that neither AMD nor Intel managed to release faster CPUs recently (in terms of Hertz) makes me hope that they are going to reconsider their current desktop strategy.

      I run a Gentoo Linux on 2.2Ghz AMD64 based system that doesn't crash and gets uptimes that spans the distance between kernels [shock: yes I actually update my kernel...]. Compared to my windows using friends with uptimes ranging in the HOURS department.... I'm leapyears ahead ;-)

      Getting an extra 100Mhz on your cpu isn't impressive. Getting an extra 10% speed boost on an already seemingly optimized/efficient algo is impressive.

      I mean I could reboot at a HT speed of 210 and say "voila 110 extra Mhz". It would raise the core temperature probably by 1C and get me little noticeable performance.

      Oh and btw with a $36 [CAD] "SilentBoost K8" my AMD64 is currently idling at 24.5C and my heatsink fan makes little noise [iirc it's rated at 20dB]. At full busy I get around 42-48C range where the max temp for the cpu is ~70C and I've never seen my cpu above 52C.

      So really you need to follow some simple steps
      • Buy a more efficient cpu (K8 or PM) that can perform the same or more work with less power (I don't care what the TDP of the K8 is, it makes way less heat than a comparable P4 and I know this for a fact since I've had a P4 at one point)
