Hi, I am using an old IBM ThinkCentre as home file server/NAS. I know Pentium 4/Celeron are hot. But idle at about 65C and max about 69C is too hot? Also about 48C for my WD Green 1TB make me worries as well.

I just re-applied thermal gel and did some clean-up inside the case and the two 60mm case fans as well, as a small form factor PC, that is all the cooling this file server had.

So my question is:

1. Is this temperature for CPU and hard drive I need worried about?

2. If so, how could I improve this situation? The current CPU is a Celeron 2.53 256K Socket 478 with FSB 533 and should has a TDP 73W, if I got a Pentium 4 2.0A TDP 53W instead, will temperature be better, helps HD temperature as well, rr should I invested for a couple of better 60mm case fan?
