GPU and CPU too hot after switching to Win7

I'm using ASUS A8Js CPU: Core2 Duo T7200 and GPU GeForce 7700 go

I switched to win7 64-bit a while ago and noticed that on the same gaming situation, the GPU temperature can shoot up to 97c. It hardly reached 90c when playing game (87 at most) when I was still using XP 32-bit.
The same goes with CPU. It wasn't even at 70c temperature, now it can go up as high as 85c.
In both situation I was using coolpad. Without, my GPU can easily shot up past 99c and automatically shut down my laptop.

I didn't do any particular tweak to my CPU/GPU. The driver for my GeForce 7700 is 179.67 I downloaded from windows update.

Is there any non-hardware tweak I can do to lower the temp? I'm worrying this laptop gonna age even faster than before.

 

There have been claims on other forums that 64 bit operating systems run hotter than the 32 bit. I haven't specifically tested it to, so I can't be certain, but if it were true, I would think this is due to do the fact that 64 bit OSes forces data to occupy more space in memory which "increases the memory requirements of a given process and can have implications for efficient processor cache utilization." ( Wikipedia).

 

It's also worth keeping in mind you are going from Windows XP 32 bit to Windows 7 64 bit in particular - that combined with driver differences could also be part of the reason for the differences. Is there any difference in performance in game that you've noticed and does it sound louder now than before? Sounds like there was some kind of limit on power/heat before and now it's running wild if those temp differences are accurate.

You might be able to do a copper mod. I'm no expert on this though, just adding my thoughts after reading the post. Oh and if it was some time between when you measured the XP temps and the 7 temps, have you tried cleaning out the fan with some compressed air, a vacuum or fine brush, etc... to get rid of any dust that might have gathered over time? It's recommended you do such a cleaning every 6 months or so max, imho.

Hmm.. no, I think for every 10 degree C, my GPU fan kicks 1 tier high, and that's the normal behavior I observed from XP-32bit. It's that noisy when they reach that high temperature. But I know the temperature is considerably higher now.

I might try to find screwdriver now and see if there's some dust there. But I think I may not know what's the real cause of the significant system temperature jump from Xp-32 bit to 7-64 bit.

 

I missed this thread on last year

It seems this is the general problem I'm having with Win7 64-bit. The thing is, I can't rely on those 18x.xx / 19x.xx drivers because the lates GeForce Go 7700 drivers is 179.xx. Looks like opening the case is my last resort for now.

I've tried to downclock my GPU to 300/250 (default:450/400) when it start hits 90c, doesn't help much... I still got 99c overheating (and eventually shutdown my system immediately)

Could it be a BIOS issue as well? I see some of them mentioned this, but none of them could troubleshoot the problem with updating their BIOS

 

Why are you walking around the problem? Just uninstall Win 7 64 bit and go back to XP 32 bit or re-install Win 7 32bit...

Edit: And for the sake of humanity, don't use drivers downloaded via Windows Update, laptopvideo2go for your graphics drivers, download the rest manually..

 

I don't know how you consider I'm walking around the problem. I did take steps down 1-by-1, not radically take the "downgrade" path.

Well...
I tried to cleaned my GPU fan yesterday, nothing.. the temperature not dropping by one bit, tried using 179.48 driver as suggested by nvidia instead of 179.67 driver from windows update... still heating 90+ c. Now I downgraded to Win7 32-bit and still having the overheating problem with 179.67 driver.

I'm downloading 179.48 32-bit version, if that doesn't do it. I don't know if there's another step I can take before downgrading back to XP 32-bit. I just can't find which driver is the best (run coolest) for GeForce Go 7700 in Win7.

 

OK... got the work around. It's an obvious but weird solution.

Are cooler pads suppose to exhaust the air from the bottom vent of the laptop or blow the air onto it?

Because I just noticed my cooler pad, from the correct position, exhausts air from the vent; And that almost doesn't help at all. Then I flipped around my coolpad; Now I got the old max GPU temperature when I played my game (87-88c).
Is it possible to get a (suppose to be?) driverless coolpad have the air flow direction blow the opposite way? I'm not sure whether this pad used to blow the air onto or exhaust the air from the vent.

Anyway... just an update.

 

Do you really want to use windows 7 that badly that you will jump through that many hoops? It doesn't matter how much air you blow into the fan, anything above 80 Celsius is HOT

Just go back to XP.

 

Thank you for your useful post. Not only you missed the point that I said the max GPU temperature back to normal, but you also offer such a pessimistic way to overcome the problem. If all the people in G51J BSoD thread took your way of thinking, they won't get a fix and thread ends at page 10 or something instead of 71.

80c is definitely hot, but normal when you're playing game (rather, it's too cool. I know G50/51 series can go up high to 95c when playing games)

 

Is your notebook fan work normally ?
I have a W3J and I tried W7 but because of a bios or driver problem the fan would not switch on when it should.
I haven't found a solution to that and I really doubt Asus would provide one.
So I still running on XP for my W3J.

 

Just take the fans out of the cooler, flip them over, and reinstall them. They were probably working against the laptop's fans, causing it to not be able to get rid of the hot air properly.

All this crap about Win 7 running hotter is crap, with the exception of David's hypothesis of 64 vs. 32 bit.

 

Wow 4 months necro of my thread.
Problem solved actually 2 months after my last reply.

The problem was actually the dust stuck on the inside of fan can (idk how do you call it), it's not reachable if I just hold my brush orthogonally to the surface.
