CPU throttling

Tonight, I my g73jh crashed while playing Skyrim. Pissed off, I took the liberty of opening it up and repasting both cpu and gpu.

Now, I don't know about the rest of you. But I HATE opening my g73. It takes forever, and is backbreaking. Tonight, I even encountered a ghost screw which had its head completely dug in so I was unable to get it out. I ended up applying thermal pasting onto the cpu from a very weird angle.

I currently have power4gear installed so that I can control the frequency of my cpu between when I'm using it heavily and when I just leave it overnight to render.

I generally leave it on moderate performance so that I can both render and do my daily tasks without much impediment. When I play a game or something, I normally turn it up to maximum performance. Overnight, I use moderate and just let the machine do its thing.

While power4gear does accurately throttle both my temperatures and frequencies, I've started to wonder a couple things.

If I change cpu usage from moderate to maximum in a split second, and then back again, and then back to maximum. Would this melt the pasting quicker? Through a process like quickened melting. If so, maybe I should just uninstall power4gear and let the i7 do its thing. Would it be better just to leave it on maximum performance and allow the paste to adjust accordingly?

I apologize if the last bit doesn't make any sense. It's 1:00 AM where I am, I'm tired and extremely angry. I'm having trouble articulating.

Any advice is greatly appreciated.

 

When you mean by melting, you mean settling time right? what paste did you use?

anyway, from what ive read all thermal pastes have its own settling period regardless of how hard you push your GPU and CPU. I think the settling period is more relative to TIME than the HEAT.


but feel free to correct me if I'm wrong.

 

I barely ever have it on anything other than max performance, it's been 2 years and everything is still fine. As many flaws as the G73 does have, it's a tank, I've had it on rendering all night before and woke up to it still perfectly fine. As far as the paste, I don't think you have anything to worry about. I repasted my friend's and he was playing Just Cause 2 on it for hours the same day.

 

you're right, settling time would be the proper term.

but would constantly changing the frqeuency of the cpu affect the paste in anyway?

take for example: you have a hardened glue, when you apply heat to the glue, it expands and changes form. And by what we know about rapid heating/cooling, eventually, the compound degrades. Is it the same way with TIM?

 

Yes in some way it happens as the same but with a more long extent. If the paste is applied correctly probably you'll need to repaste it once a year, I'd not once in two years.

Btw if you're running a sandy bridge CPU and your temps looks fine, remember that all g series laptop has the throttling bug, you're forced to use ThrottleStop to block it from throttling without reason, degrading performance in each task.
