Some questions on my latest scrap finds

[FDIV]

Below you will see some chips from my last scrapyard run. My questions are: In the first picture you see an IBM chip out of a desktop server wich was in the ps2 era. Also on this board was a 186 processor. This chip, however had a fan directed on it. Does anyone know the function?
In the second picture you see a clone of the first mips design, the r2000. I cannot figure out who made it though. I have never heard of a "pace" chip manufacturer. If you have I would love to know something about it.
In the third picture you see an unknown ti chip. This chip was a socketed pull but I was not the one to pull it so I don't know anything about the board. Does anyone know the function of this chip?

It is made by Performance Semiconductor.

I'd be interested in the Pacemips if you wanna get rid of it. And the board it's on.

I have desoldered the pace and scrapped the board (boards take up to much room so I typically don't keep them.) I am not really looking to sell the chip. I do not have duplicates of it.

Sorry,
