6300 Temperature query

[ben_moore34]

Hello

Had my Core 2 Duo 6300 & DS3 set up for about a year now & have decided to overclock it slightly.
I got hold of INTEL TAT for temperature monitoring & found that on idle my presently un-overclocked readings are

CPU0 CPU1
60 C 58 C


under load of 100%

CPU0 CPU1
68 C 65 C

This is using stock components, cooler etc.
All I have done so far is to set my fan mode to Legacy in the bios
Case is ANTEC Sonata

These readings look higher than I expected. Is it recommended that I get a different cooler before I attempt anything?
Does ambient room temperature have much of a bearing on these results too, it is fairly warm in the house with the central heating on?

Many thanks in advance

Thanks for the quick replies

Have tried those fan settings in the BIOS.
It's made some difference, I'm now getting
63C & 60C under 100% load and
55C & 54C idle

Would it be advisable to remove the heatsink & reseat it?
From what I remember when I made the computer a year or so ago I didn't use any heat paste, just a little pad that came with the CPU.

Cheers
Ben
