A few weeks ago I bought a cheap NMC- 5VMX motherboard at the bay. This one is identical to the Epox EP-MVP3G2 which is a very fine SS7- board with the VIA MVP3 chipset.
After some not really successful experiments with socket A systems and peltier/- air- cooling I was curious about the effects of a tec1-12715 (about 110W true pumping-power) on a watercooled SS7- system.
I also own a 3dfx Voodoo 3 3000 with 5,5ns RAM and wanted to test its overclocking capabilities under water. I thought it might be quite successful because this card is getting really hot, but I got it with a slightly modified air-cooling up to 200MHz.
And, last but not least, I thought maybe I could get some more out of an AMD K6-III+ than the popular 600MHz.
First & short, I failed. But ...
lets start from the beginning. First I had to mount the watercooler on the board.
No problem, but wrong board. With a max. fsb of 112MHz the VIA-based NMC was not the board I needed. After some googleing and reading I found out, the Gigabyte GA-5AX could go, with some luck, up to 140MHz.
One year or so ago I had built a system with a GA-5AX ...
..and, as boards have no legs, it was still there where I put it a year ago.
After some cosmetic surgery the board looked ready for the warpath.
The watercooler fit quite well, but I had to make room for the Peltier. With 2 little pieces of sheet-metal I made 2 modified mounting clamps ...
and everything went fine. But, problems ... . First, if I would try to cool the CPU directly with the Pelt, the Voodoo card would get no cooling water, but hot sauce. Bad idea. So I had to get the graphics- adapter out of the circuit. Bye bye Voodoo.
Second problem, the radiators. If the water-temperature should go under environment- temperature, the radiators will warm up the water. Solution would be a bypass to cut the radiators off from the circuit. All I needed was some tube and some connctors ... all I needed was some money
.
So, everything was a wild-goose chase (got this from the dictionary
), and I'll try again when I'm rich.
Next posting will be about sunrise in dark pc-cases ...
so long ...
