DERG.
I first thought a T972 might be a piston engine or some obscure eastern invention and nearly passed by. Google came up with RR Trent 972.
There are so many abbreviations in aviation, it would help to put a bit more in your post.
My A/C is Airbus A300-B4 and the GE CF6-50C2 normally runs at 80 to 100 C with limits of 160 C continuous and 175 C transient for 15 mins.
Hope this helps.
