DIY Heatpipes for everyone

Just a (heat)pipe dream?

I'm astonished that these thingies haven't been mentioned here before ...

Short :

A heatpipe, that transports more than 45 watts (that should be more than enough for most PCs here). The cool thing: Available in different sizes AND it's flexible(!). You can put it in every PC. Cool your (low power) CPU, cool your graphic card. Just attach one side of the heatlane to your CPU heatsink and the other to your case. Yes, yes that's requires some degree of DIY crazyness, but we're talking about silent (not quiet) PCs.

Price is moderate, about 25 USD. You'll have to order minimum worth 5.000 USD. Or buy here in Germany: http://silentshop.de/.

I'll look forward for crazy hacks here

I was in touch with these guys a while ago. It isn't as flexible as you might imagine. You can bend it into place once, but bending it any more often than that (like if you need to add/remove hardware) is likely to break it. Also, at just 45W, you'd need 2-3 of them for high-powered components. Cost per pipe is also a lot higher than for simple heatpipes.

Still, if you are looking at a system that is already fairly low-power, this could be an interesting option to help you run passive.

Some german website had a PC set up using these things for cooling, but I forget the URL.

MSI Mega Barebone with3 GHz CPU completly passive. Crazy thing. I'm sure, we will see mor ehacks like this. You should be able to cool a 35 watts Mobile Athlon 64 with two heatlanes.

Bye egghat.

As noted in the other forums, a Pentium M can match a P4 3.2-3.6 while at circa 21 Watts. The new CT-479 conversion kit makes mounting a standard 478 heatsink (or XP-120 heat sink) a bit undooable, but this might make an interesting way to jury rig a fanless Pentium M. 45 watts...Hmmmm.

It is only 45W if the hot end is at 100C

These heat pipes will also work at reduced efficiency unless they are oriented in a "heat-travels-upwards" direction.
