New at OC, a few questions if I may

I found this forum to be very useful, thanks for all the great guides and answers. I did not find answers specifically for my questions so I thought I would make a new post.

My system:
MSI P35 platinum combo
4 gigs - CORSAIR XMS2 - TWIN2X2048-6400C5DHX 5-5-5-18 1.8v
Intel Q6600 - stock HS and fan
Antek Case of some kind.
2 HD one DVD
Windows Vista 32

Overclocked:
FSB 333
Memory 833
vcore bumped up to 1.3 from 1.275

I just built the system yesterday. I used the stock thermal grease. My temps yesterday before OC were 32-33 idle and 48ish full normal load. Prime 95 torture test max temp 57C, ran for 20mins. Today after I OC'd, idle around 35C and Prime 95 torture test max temp 50C, but I downloaded SANDRA during part of it. OOPS! Ran prime 95 for 38 mins no errors.

So my questions are, can the thermal past bond in less then 12hrs operation? Is that why the the max temp is so different? I am a bit perplexed. Do I really have to do 24 hrs of stress testing? Thats a long time. Maybe video games would stress the whole system more, should I tell my wife I must play games for 24hrs straight? Lastly, can it really be this easy? I am worried that my computer will blow up like a meth lab and blast me to the neighbors.

Thanks for your time,

If those are the temps read by CoreTemp or RealTemp, then they should be fairly accurate. As to why the load temps were lower could be a number of things:

1.) a change in ambient temps. Perhaps your room got much cooler?

2.) You are running blend test instead of small FFTs in Prime95

3.) You are running large FFTs instead of small FFTs.

4.) Your cpu sensor became jacked up over the course of 12hours.

I was running blend test, will run small FFTs now.
