T41 + lowering Temp +undervolting

[T400plus]

I got a 1.7 sl7Ep dothan into a 1.6 banias slot (A t41 2374 7fu). It runs hotter now (much hotter but
not good for any toasting).
I am undervolting the cpu at 1.7 , but I dont notice ny drop in temperature( i.e > 2 degrees).
any pointers ?.
I have applied a cheap thermal paste on the cpu.Which is a reasonable paste.I dont want to waste any silver compound on a intel pentium M.
