I tend to agree Thom. Yes the chip is fried, but so is the wiring and everything else at 300'F. The response of the sprinkler head is minimally affected in a 12 Sf room by the higher temperature listing, but it gives the IT dude a warm fussy. I saw some suggestions of installing the Equip in cabinets. While special Cabinets do exist for servers, they are very expensive, and they have problems controlling temperature in the server. The biggest killer of servers is heat. not from fire, but self generated heat they can't get rid of fast enough. IT magazine had an article on the server's at Microsoft or Intel and the way that the input and output cables arrangement could block or disrupt air flow over the server, and cause it to over heat. Spend the money on more A/C and leave the 360'F sprinkler in place.
