5 GHz Project: CPU Cooling With Liquid Nitrogen

Video 11 To Download: 5.25 GHz With A P4, Continued

While the first THG video controversially demonstrated the overload problems with the AMD AthlonXP/MP and caused a storm in the industry, the second video was a short and snappy guide to unleashing the almost unfettered overclocking potential of every AthlonXP/MP. The third video dealt with installing powerful water-cooling in a PC housing. Only first-rate components were used that represented a good investment for years to come. Video number four showcased Intel’s IDF 2002 while number five came to grips with the P4’s HyperThreading. For it, we pitted a P4 with 3.6 GHz (without HT) against a P4 3.06 GHz with HT.

The sixth video introduced a 4.1 GHz system and proved its potential. At the time it was one of the world’s fastest PC systems. Video 7 showed the highlights of IDF 2003. Video 8 handled the set-up and assembly of a compressor cooling system for extreme overclocking while maintaining stable operation. Temperatures of -52°C on the CPU head can be achieved. Another film (No. 9) dealt with highlights of IDF 2003 - details on the Pentium 4 with Prescott core. The tenth video focused on the Athlon64/64FX : How fast is the CPU against its rival from Intel ? Is there any movement on the overload problem ?

The new THG video number 11 : Cooling a Pentium 4 with liquid nitrogen and attaining a clock rate of 5.25 GHz

Our new video, number 11 in the series, has more of a theoretical nature. It shows how, by adjusting the FSB, the clock rate of a selected Pentium 4 is gradually raised to reach a record value of 5,255 MHz. The whole time, the system has to be topped up with liquid nitrogen.

    So would u have to cool it constantly? or.. wat?
  • If they stopped cooling it the processor would die.
  • Now, with that big of a heatsink how do you plan to close the tower? How do you plan to renew the liquid nitrogen without blowing up your PC
  • you will notice that this was done outside... so not very safe I bet. Also you would never be able to keep switching the system on and off as the ice would damage the pc

    I couldn't help but think that there was a lot more they could have done to insulate the rest of the system from the CPU's immediate area .... I'm sure this system must have gone onto a crashing spree once all that ice built up and started short-circuiting all those electronics around the CPU's base .... for one example, they could have gone as far as to coating that area with silicone, i would think; or in the vary least, covering that area more to protect from the super cooled 'steam' flowing over the top of the copper tube and down onto the motherboard.

    Secondly, the over-use of thermal pastes ... from my understanding, application of thermal paste between a chip and a heatsink is supposed to be EXTREMELY THIN and evenly spread; any excess paste REDUCES thermal performance and just splotching it on can easily introduce air bubbles which would cause 'hot-spots' wherever a bubble lies.

    If your going to draw attention to yourself by breaking some world records, it would be probably a good idea to do everything you can to make everything as perfect as can be ... for example, cleaning up the copper soldiering residues to 'good enough' levels isn't Good Enough!, go all the way and use scouring pads, polish and some attention to detail and people will respect you the more for your efforts and clean presentation. A key to success in life = Strive for excellence in whatever you do! Don't settle for second-best.

    I know it's late, but you guys are clowns.

    They did it and then took it apart and threw it in a box. Sorry it won't fit in a case and it wasn't shiny enough for you nitpickers.

    Let me know how cool yours is when you get done.

    If you're going to post garbage then don't post at all.
