Are these temps good for a Q9450? - Page 2

Anyway, that is how TIM must be applied to these HDT heatsinks. If you don't apply it that way, then you get air pockets which means the heat transfer from the CPU to the heatsink is very limited which results in temperatures that are higher than what they otherwise should be.

So just fix the thermal paste application and try again.
Oh, sorry. It's in pretty open space.

I had a feeling it was (because you didn't answer), but I still had it on my mind.

So yeah, as long as the thermal paste is applied correctly to an HDT heatsink, the temps should be fine.

No I'm talking about Tcore shouldn't exceed 75C..

But exceeding 75°C while stress testing is not going to cause any harm to a Q9450 (or to my E8400 for that matter). At worst, reaching or exceeding 75°C will just cause some instability due to the extra heat.

As you know, the Tj. Max is 100°C. That means that the CPU is supposed to either throttle itself down or turn itself off if that temperature were reached because that's supposed to be about the point where damage can begin occurring.

Of course, I wouldn't want anyone to consider ~75°C (or even 70°C) to be a good core temp when stress testing because even my little Tuniq Tower keeps my CPU well under 60°C at all times. However, it's not a seriously bad thing if a CPU like the Q9450 reaches or exceeds 75°C.

I ran my Q9450 @ 3.5Ghz on 1.35vcore with max temps on 69-70 degrees, so this should be fine

What happens if the vcore is set that low while you try to overclock to 3.2GHZ or above?

With your vcore of 1.184V at 3.2 GHz, I would expect load temps to be lower than that by about 10°C with a proper TIM application on the Xigmatek Dark Knight.
