I put a lapped eVGA nForce 680i LT SLI south bridge heat sink on the card along with a ddr vram sink on the back of the card.

I tried 200mhz but the system crashed and upon reboot the windows folder was missing. :o Very odd, its not in the file system tree nor can my coppy of Active@ File Recovery find it. So I'm going to have to reinstall windows on the syetem.  :-/

I will be adding a nice heatsink to the card with mx-4 thermal paste for conductivity.

I choose to use an 80mm system fab flowing directly on the card for cooling.

I will overclock and benchmark the card with original cooling and with modded cooling and post the results.

I have no P3 system to test it on, so I will use my XP3000+ system and clock the cpu accordingly :) Will set it to 1.4Ghz, should be fair :) both 512KB cache, same Ghz.....that's where it ends :)

Nice pick of thermal paste, MX-4 is some nice stuff.
Also if possible downclock via cpu multiplier. If you lower the FSB the Ram and PCI bus might be hampered.


EDIT
Once I get windows reinstalled I'm going to try to OC a tad more. I'm thinking I can get around 192~195mhz out of the card. After that I will try some of my other 3dfx cards, then put my fx5600 in the system.


EDIT:2
I had to wipe the system clean. I might go back the using a ide hdd in place of the sata drive. I'm thinking some of the problems I'm having are with windows 98 not liking sata drives.
