does the G1Sn have overheating problems

so at the 3rd time i sent my G1s-B2 in for overheating, they decided to replace the motherboard. they couldnt tell me whether it was the G1Sn or not, but the tech support fellow said that any G1s that needs motherboard replacement due to overheating, it gets a G1Sn motherboard.

so, how does the G1Sn with the 9500M GS handle heat? i'm guessing its better than the worthless 8600m correct?

even tho i may be moving on to a desktop, my brother needs a laptop so i was wondering if i should just give it to him instead of selling it.

 

There is speculation of issues with the 9xxx series just like the 8xxx series. There is one great (and scientific) article concerning the cards in the new MacBooks and may apply. I believe it was on engadget if you want to take a look. The 9500M is 65nm @ 25watts and the 8600M is 80nm @20watts. It should be a bit cooler as it is smaller There are many users that have replaced motherboards and no hardware issues. Check the G1 owner's lounge for more information.

Edit: I do not know if this applies to your graphics card, but it may be good information or reference.

ouch, nvidia has done it again. looks isolated to the 9600m to me, been looking around for 9500GS and G1Sn problems and it seems that it should be ok

 

it never had heating issues. Asus makes a point of replacing the g1s board for the g1sn. its the same board with a different vga card. Overall the unit was reliable and still is. It was our most popular model up until the g50. i do see rma for the vga card here and there but certainly it is not inherent and does not run in the family but the 8600 in it is a suspect though definitely not by any means an rma waiting to happen. years of gaming can be had out of it without any issues. thermal breakdown is inevitable in any microchip.

 

There were two separate problems with the G1 series. The first was with the original model's thermal paste being inadequate. The second is obviously the NVIDIA 8 series fiasco.

 

the thermal paste has been known to dry out on alot of cards. the thermal paste issue actually affects alot of products. thermal pads and dry paste (depending on the source) suck compared to arctic silver (nothing to do with temperature). the problem with arctic silver is that it does void warranty if you so choose to apply it

 

Yep, I also noticed they switched to pads shortly after this. It was only the first rev of the G1 AFAIK that had actually too little thermal paste specifically.

 

i ve handled enough of these to know that there is ALWAYS room for improvement. No brand is an exception.

 

thank you

i can now sell my g1s(n) with a clear conscience

the problem with the 8600m was that it was running at a constant and unstable 97 degrees even tho it was underclocked by 30%. the first 2 times i sent it in they said they cleaned it out and replaced the thermal paste (yes, twice in the span of a month). they finally budged

the temps of the 9500m are worlds better after a couple hours of playing wow. nice, cool and stable. hell, it even feels faster than the crappy 8600m hehe. it was delivered this morning

 

Good to hear some decent progress with a 9500.
I never heard peep back from ASUS (etailer went silent too) about my 8600 that's been obviously problematic. Artifacting, never non-cooled/modded operation possible etc etc.
But of course the C90s/p seems headed the way of the Edsel, with a lot less press coverage though.

 

I had ASUS NL replace my G1 with a G1Sn (they skipped the 8600GT straight away, lol). Running windows 7 build 7048 x64 and 180.70 vista x64 drivers.
Everything else from asus for vista x64 installed smoothly and got the hotkeys and animations to work also.

Without any tweaking, overclocking or undervolting, im getting 7288 3dMark05 points, and temps are ~75 (77 max) for CPU and ~85 (87 max) for GPU. Seems smooth.

Ill post my progress when I get to play around a little with undervolting and overclocking.

 

mine doesnt go past 70 degrees (and usually sits at 65) after quite a bit of gaming (no cooler). room temp around 15-20 celcius

 

That's much cooler than my stock G1s...so that alone should be worth the upgrade haha.

 

hehe souroull thats pretty low.

Now, after installing a new hdd and reinstalling windows 7, I've encountered an odd problem.
Whenever I run 3dmark the fan hardly accelerates at all! It does so only occasionally, then slows down again. Shouldnt it run full blast when theres some intensive applications going on ? Im worried this could take my gpu temps way higher.. is there any way to control the fan to go max speed when in games ?

the driver I installed was 177.79. I've been overclocking some now and its odd that the fan thinks it doesn't need to go faster.. lol, I think it should run full speed all the time 3dmark is running!

e: my gpu temperatures are climbing because of this

e2: I noticed the fan only speeds up 100% in the cpu parts of the test, so clearly its not responding to GPU stress. How can I change this ?

 

actually, you cant

the sensor only speeds up the fan when the cpu heats up, not the gpu

rather stupid but oh well. if they're on the same heatpipe, the heat of the gpu will transfer to the cpu and it'll speed up the fans tho.. but then again im not sure

get hw monitor and monitor the temps while running it?

 

the 8600m was idling at 65-70, and with a few of the drivers i tested, up to 80

so yeah, hehe

i almost want to keep it but ive been wanting a desktop for a while now

 

Yeah, well Im thinking the connection on the gpu and heatpipe isn't too good atm. No way they would have over 20C difference in temps. I've been monitoring, stock gpu goes to ~89 and cpu stays at 70-71. No way im tearing apart this before warranty though, so guess im going to have to get a cooler.

 

send it in, they'll replace the heatsink and thermal paste and clean it out for you

 

This is a new machine. Just got it from RMA after a long wait, not about to send it back soon. Just going to have to find workarounds for now.. any suggestions besides a laptop cooler ?

 

that still sounds pretty hot tho, maybe they forgot to apply some thermal paste lol dunno

 

I went ahead and replaced the thermal paste on gpu & cpu today. Was actually pretty straightforward and it took me 2 hours from shutting down to starting it up again, but that was for the first time.

Don't know what kind of material they used but it was rock solid on the CPU, not so much on the GPU. Well, it knocked 6-7 C off my max GPU temps and I used about 8 years old arctic silver 2. Couldn't be bothered buying a new tube just for this, might do later.
91 recorded max so far at 600/460. Yeah, still a bit on the high side but it hovers now at around 90C, before with lower clocks it was around 95-96. Hope the curing knocks few additional degrees off.
