Thanks again everyone.

Just wanna know something before: Do you think I will have to apply any thermal grease if I go with the 1.6Ghz DIP Switch trick or will the thermal pads supplied be enough to get it going? (I just hate applying thermal grease :P)

Man, I wanna thank you again for this review, this is one hell of a deal now!
The stock heatpipe sink that comes with the laptop does have a thermal pad type thing, but it looks like something half decent. I'm honestly not sure if AS5 would make too much of a difference. In general, these CPUs don't run too hot. It seems like most of the system integrators aren't pushing AS5 at all, so it makes me think that perhaps it doesn't make too much of a difference.

chuck, i tried applying AS5 to the GPU/chipset and ran into the same problem: there's too much spacing. What I did was apply a thicker layer of AS5 than you're supposed to, thick enough so that it does leave a print on teh heatsink when I go to put it back on. Now this doesn't work so well... the cooling is definately the same or even worse than before. I'm going to go out tomorrow and buy a copper/aluminum sheet (real thin, i think 1/16 inch will fit) and cut out a piece to put in-between. I'll let you know how well that works.

Hmm that is what I did maybe then. heehhe

Never noticed a different in GPU temp, no real way to monitor it unfortunately.

Alrighty, I look forward to your results. I had been contemplating this, but I'm not exactly sure how thick of a plate I need and if would really work. I mean die-to-copper plater-to aluminum heatsink can't be very good for heat dissipation.

Fry's Electronic sell a 4.5mm thick ICE thermal pad. With electronical power connection, it produce a nice ICE cold side. Heat disperse out of it on the otherside which contact to the heatsink.

I haven't tried to see if it fit, but if it does...boy nvidia baby..it will do easily 350/700!!

i bought 1/40 inch thick copper sheet at the local hardware store, cut a 1/2 by 1/2 inch square piece which fits the GPU exactly. The problem comes when you're cutting: it is very likely to bend, so you have to try to straighten it. I sanded it down a bit in an attempt to take away the marks and flatten it. I shouldve sanded it a bit more, with finer sandpaper. Oh well... Then I cleaned it with isopropyl alcohol and I applied AS3 to the rough surface and simply pressed the smooth surface onto the GPU (shoulve check that one too for height distribution). Anyway, what I ended up with was something marginally better than the stock pad. I'm now running 300/600 without overheating, though it froze for a sec in HL2 at one point and introduced artifacts after resuming. This is much better than the thick AS3 solution i had before, so essentially what I ended up doing was fixing what I messed up. If I have time later I may retry this, using a smoother, sanded down, perfectly flat piece of copper. I'll have to get the engineering department at college to cut this and flatten it for me =D . This is maybe 30 minutes after applying the AS3, so I suppose I should let it burn in a bit, then retest.

smilepak, that ICE pad is Peltier and that stuff is very expensive... Also not sure where the pwoer is going to come from...

Did you apply AS3 for the GPU surface-copper plate contact? If not, that could greatly increase cooling performance. No matter how smooth it may look to you, microscopic hills and valleys in the plate/gpu surface would compromise heat transfer.

EDIT: And uh, thanks for the sticky. It's a great honor.

It's a great thread! (and this is coming from someone who has written 2 Z71v reviews and gotten one published! )

Yes, AS3 was already there (remember that i already had a thick layer of AS3 there. I didn't bother to remove it, just made it thinner and stuck the plate there). While i didn't apply AS3 to both surfaces, i was hoping that the AS3 on the GPU surface would adhere onto the copper plate. I think this entire cooling upgrade may be worth it if you do it correctly, with a good, flat copper plate. It'll let you push your GPU slightly higher.

I took the laptop apart again and took a closer look. The gap between the GPU and heatsink should be less than 0.02mm.

THis is really nothing. In anycase, the AS5 I place seems to be working nicely. What I did this time around was buy a pack of 3 thermal pad tape from CompUSA for 3.99. I then stick that on the heatsink outside of the CPU area. This will allow contact with the video RAM.

So far seems to be pretty good.

After putting the heatsink on, I couldn't sllip a piece of paper though the so call gap.

Eh, well I guess their heatsink production isn't very consistant then. I know there is a gap much larger than .02mm on mine.

Does the PC4200 ram works well with 400 fsb? It underclock itself?

Wow, awesome review, you just convinced me to get the 71v.
I had been on the fence because of the screen, but I think you're exactly the same type of person I am when it comes to that stuff. (I have 5 dead horizontal lines across my CRT, I'm sure some people would freak out over them, but I don't even notice anymore)

Just a question, where did you order your stuff?

1CenT:
Same question as above, where did you buy your notebook?
I'm in Vancouver as well, and am trying to find someone who will give a decent warrantee through the shop (I guess they'd want to build it in that case though), instead of through ASUS. Any idea what Atic is like for this kind of stuff?

Great review, but one minor thing that has been bugging me since I read it. >.< You say that the Z71v won't read your Sony's memory stick, but you can clearly see the Memory Stick port on your pictures. :x By Memory STick, did you mean some other media, or the actual Memory Stick? I was able to read my 256mb Memory STick Duo without a single problem...

Anyways, about the GPU problem... is there a way to use something--like a cooling pad--to bridge the GPU and the heat sink?

Odd, I assumed since the filler card for the card reader was in the shape of a SD card, I assumed it was for SD cards only. I never did try my memory stick on it. Only assumed. Sorry about that. If it does indeed work with memory sticks, so much the better so that both my cameras will work with it.

The whole point of taking apart the cooling system was to check if there was any difficiencies with it. If you put a crappy thermal pad between the heatsink and GPU, it would defeat the purpose really of taking it apart. What they've got on there is adequate but not exactly good.

As for a shop in Vancouver, check out Anitec.
