It did look like a turbo fan engine

Ok I have two questions:

1. How does that turbo-fan thing fit into the case?
2. What is keeping the motherboard from breaking under the weight of that thing?

I would think at that point it would be safer to just run a water-cooling system instead of that crazy thing.
Wow... just... wow.

I'm just wondering where he or she plans to use the thing? On the sun? The surface of Venus?

Maybe a forced liquid nitrogen cooling system would really make them happy?

We had a really good helium based cooler for our parametric amplifiers on the AN/MSC-46 SATCOM recievers...kept the temp to 10-13 degrees kelvin...this was until "HOT" para-amps were developed...but playing with helium at these temps is FUN!!!! Freeze a frog in no time..plus you have large bottles of helium to play with (hey..I was only an E-4 then)....

Yee gads what would they need such a monstrosity as that? Have they overclocked their AMD that much...oh wait, it's a Pentium...you're right, it must be an airplane, Pentiums don't need that much cooling...

If you can believe it or not we used to do the same thing using liquid oxygen of all things!! ( and we all know how stable that is!!!).
One of the most boring jobs all us E1 ti E2 Airmen used to get was filling up the liquid oxygen bottles on the jets that would fly the next day, We used to throw bugs and any thing else we could catch into the over spill, So we could watch them freeze instantly when they hit it.
Gee when i think of all the stupid stuff i used to do as a kid it makes me wonder!!!

Pentiums DIDN'T need that much cooling. But now they do. Why do you think Intel is pushing the BTX motherboard? To cool the VERY hot Intel CPUs.

See chart below for more accurate (nearly) current information:

Code:


Processor Model    Frequency (MHz)    Nominal Voltage    Typical Thermal Power    Maximum Thermal Power
Athlon 1400 (T-bird)   1400         1.75V         65 W         72 W

Athlon XP 3000+ (Barton)2167         1.65V         58.4 W         74.3 W

Athlon 64 3200+      2000         1.5V         +/- 70 W*      89 W

Pentium 4 3.2 GHz   3200         1.55 V         82 W         +/- 103 W*

Pentium 4 3.2 GHz EE   3200         1.55 V         81 W         +/- 109 W*

Pentium 4 3.2 GHz E   3200         1.3-1.5 V      103 W         ?

Pentium 4 3 GHz E   3000         1.3 V         89 W         ?

Note that the P4 3.2ghz E and the 3.0ghz E do not list maximimum thermal power as Intel no longer tells what it is. So at present AMD is the cool runner not Intel.

Something to note is that the E version is the newer Prescott core made at 90nm, which if the core had not been revised would have lowered the wattage. The performance did not increase compared to the older Northwood core (the EE is a Northwood core and cooler), in some tests it is slower. Even the northwood core is hotter than the Athlon 64.

When the Athlon 64 goes to 90nm it should cool down at a given speed.

I couldn't find wattage for the Pentium 4 3.4 ghz E or the just released Athlon 64 3800+. I expect the Pentium 4 to be even hotter but the Athlon 64 may be cooler (lower cache=fewer transisters and less heat, but higher memory bandwith in the 939 pin socket).
