VIDEO 18 TO DOWNLOAD: Fascination Surrounds The Oil PC

The Do-It-Yourself Oil PC: Pour eight gallons of vegetable oil into the running benchmark operation and the silent Athlon-FX-55 system is ready. A GeForce 6800 Ultra as well as other components are included.

Our video 18 follows a completely new approach to the cooling of a high-end PC system: eight gallons of oil are poured here into a specially prepared case with powerful components. And all that during benchmark operation!

The videos from the Munich-based THG lab have been followed by a wide audience ever since the first film in 2001. As we did for our previous films, we offered Video 18 in three different formats from the get-go. All the while, we've always attempted to achieve an optimum picture quality with a comparably very low bit rate.

In order to cater to the wishes of a few readers who don't want to install an additional video codec, we offer the new video in WMV9 format for the MS Windows Media Player as well as for Apple in Quicktime format (H.264).

Apple has caught up with its Quicktime format (7.0.3 Pro), which is much easier to operate than the competition. The video was coded with H.264.

In addition, the file is compressed with a ZIP packer so that, as a result, a 20 MB file is ready to be downloaded. A playing length of three minutes and 45 seconds with stereo sound results in an average bit rate of 5.7 MB/min, or 93 kB/s.

Our preference for the DivX codec has changed, since the new version 6 is less suitable for encoding than its predecessor 5.2.1. Thus, for this video the "old" version was again used for now. The market for compressing procedures is transforming altogether in that the Microsoft WMV9 codec is displaying good characteristics similar to the DivX 5.2.1 and is much easier to handle. Apple's Quicktime Pro 7.0.3 has also really caught up and now works with the modern H.264 codec. The handling is the easiest thing in the world and clearly better than for DivX or WMV9. You can convince yourself by simply downloading the Apple version of the video.

The new video can be downloaded here:

Download video 18 in the DivX format


Download video 18 in the WMV9 format
Download video 18 in the Quicktime format

If the video doesn't play, then you can download and install either DivX Player, MS Windows Media Player or Apple Quicktime Player.

does anyone no how long a computercan lst doing this? like after six months of being submerged and the oil was rinsed out. would the computer still work without the oil? or would the oil would decrease the computer's components life spans? Or increase it?

ive seen some run for a year at 80 degrees C with out anything cooling the oil but with a zalman water cooler hooked into it to cool the oil it will run at 30c for as long as the cpu lifespan

"On the motherboard http://en.wikipedia.org/wiki/Motherboard in the area of the CPU base, the oil is responsible for increasing the capacitive resistance between the individual wiring. In short, the oil acts as a dielectric material. Since very high frequencies occur on the motherboard, the capacitive resistance goes down. Accordingly, this then influences (or tampers with) the digital signals, particularly in the area of the CPU base. After all, 939 pins are located there in a very tight space."

This is the first article I've seen mentioning the sealling of he base of the CPU. Other's some in the forums are concerned that there is not enough cooling flow under sockets.. since liquid is thicker than air it tends to want to create hotspots here. Air will swell and vent heat more. This article notes that they "had" to seal the base for stability. I understand the dielectic effect. But anyways for a socket 775 anyone know for sure what we should do?

Why not use mineral oil, or better yet, transformer oil? It would have better electrical properties than cooking oil, and probably better thermal properties, too.
