Is my CPU overheating

[wedmonds]

Hi People,

I replaced my graphics card recently as it was giving me blue dots underload.
The new one seems to be doing the same and I am obviously thinking its something else.

I am pretty confident I applied the artic silver compound correctly and evenly and wondered if anyone could advise on the temps I am getting or what I could try to resolve?

I looked at other threads and came up with PC Wizard 2008 for the top one and cpu-z for the bottom.
Just fired up Speedfan and got

34c
33c
29c
29c
on idle
Then i put COD4 on for 5 minutes at high settings and got
48c
39c
37c
37c

Blue dots have gone now????????
If it was a heat issue surley the dots would stay?
I have seen a few peope mention the multiplier, could this cause a problem as I have not touched mine through lack of knowledge.
