    I add some aluminum pads to heatsink.The max temp is same,90C.
    The only difference is that it take longer to reach that 90C.

    That is the hotest part of the radiator. Unless you've increase the fan intake grill, a good part of the fan intake air comes from within the laptop assembly. So air is drawn from any entry point into the laptop (even a slight amount from the CPU raditor if the CPU fan happens to be off). If you happen to properly seal your exhaust raditor to the output of your laptop, then there might be enough negative pressure inside the laptop to suck part of the already hot exhaust, back through the hottest point of the raditor. Heat resistant solution recommended if anyone attempts to block this "left" hole to avoid chances of anything melting and making a mess.

    This is exactly what I have in mind but cutting the aluminum tape with scissors is so hard. It keeps sticking and I keep getting jagged edges. Lol.

    Sorry. I just edited my post. I meant to use the word "radiator", and not "heatsink" as you may have interpreted.

    I am not sure coupling the GPU and VRAM heatsinks at the source as you did is a good idea, as the VRAM may not have the same heat tolerance as the GPU. GPU might overheat VRAMs by doing this (assuming the heat transfer is siginicant). Better couple the radiators instead. Of course heat sinks on the GPU will help as long as you provide air flow over them.

    The intake part I've already figured out.

    When you look at the fan, right around the outer diameter, I'm going to place foam all the way around it. When I replace the cover, the fan will only suck in air from the vent --not inside the laptop. My idea to isolate the fan's intake was the first thing I thought of actually but somehow failed to mention.

    As for the pipe touching the fins, yes, it'll be the hottest part but adding tape there can't possibly help alleviate some heat, can it?

    It's not really the fan but the shape of the assembly where the fan sits (inside) and where that assembly is screwed down into the chassis. If the exhaust of the fan is skewed a little to the left, we'd have no horizontal alignment problems.

    The fans sucks air in from both sides. This is important to remove heat from other components inside the laptop and in case the intake grill gets blocked at some point (loose piece of paper floating around on your desk, etc.). So you won't be able to fully isolate the intake within the laptop.

    Given the intake situation, adding tape to the left fins of the radiator helps prevent reverse air flow into the laptop or exhaust recirculation through those hottest radiator fins.

    Does this guide relate to the NP9150 too, or is the cooling system completely different in that model?

    As bad as some of the temperatures sound my currrent macbook pro with the 9600m gt card usually hits over 90 playing any game even WOW. Even Internet surfing will result in temps close to 80. Apple laptops tend to run very hot, apple insist the temperatures as safe even those close to 100.

    My np9170 should come soon, so I will try this foil thing when I get it.

    dude,seriously, something is wrong with ur machine. how exactly do u apply the paste? and u do make sure that u tighten the screws diagonally and as tight as possible?
    just doesnt make sense that even propping up the back and repasting with high perf. TIM wouldnt lower ur temps!

    Not recommended though, it's specifically designed to suck in air from the side, note the cover has holes strategically placed near GPU and CPU, to draw air through those parts as well. I bet you didn't see much of an improvement with that specific change.

    Yeah that's not really going to help. Try using as little of the aluminum tape as possible as I mentioned, just seal up the gaps. Covering copper with flat aluminum in itself is not a benefit, just a detriment. At least if your pieces of aluminum had extra surface area, then maybe yes (fins).

    When you repaste, try to spread the paste evenly, the GPU doesn't have a cap, spreading is generally recommended for that. Though lots of users here have also reported nice results with the blobs or lines of paste.

    Anyway, if it takes longer to reach a certain temp, that's an improvement. Watch also how quickly the temp drops when the fan finally reaches speed max or max-1 etc. Nice sharp drops means your cooling is working well. Taking longer to heat up = cooling working well.

    I'm not hijacking here, but guys, I've worked for some hours analyzing and problem solving, and I've successfully made a complete consolidated summary of the heat issues many many users are having (especially me), along with a couple unique solutions. Just about anyone with a Clevo 150 or 170 model can benefit! Feedback is welcome :)

    i just got my 30mmx30mmx10mm blowers, and i can fit two in the empty ram slots in the bottom, and if i move the subwoofer somewhere else, like into the hdd caddy i could fit another two. also i could use the hdd caddy for power and control of the fans, so that way it wont void the warranty.

    That subwoofer is worthless. Its value is to take out so you can have more space for some cooling apparatus. I'd put it into the box and just reinstall if you needed warranty service, lol :D

    I was thinking also to add (solder) heat pipe on top.get thin cooper pipe and make heatpipe,or add cooper pieces on top by soldering them for good.
    I would love to buy spare heatsink unit for cheap.They are same as on 170HM?

    also fan from other laptop,small laptop like hp mini may work.fan blow air to the side.
    i will try to find info about size of this.

    I took the heatsink for the vRAM off, and used the foil all around to attach the fan to the radiator. I found putting foil underneath made more difference than on top. I noticed the thermal pad for the memory is gel like. And googling gel thermal pad, it seems these may have better heat transference than Phobya, 12w/mk. So I left em, won't replace em.

    I have a pack of 8 copper vRam heatsinks coming, will use that. And since while at it, will repaste with ICD7 since I think it works better with laptop heatsinks (uneven etc.). I think Prolimatech PK1 is probably amazing, but only if you have a desktop heatsink that is mirror smooth/even. I'll use the washer method also. With all that, I'll be done with trying to improve the cooling. I'll apply all this for the CPU, might as well while I'm at it.

    8 pack heatsinks @ amazon $8 prime elegible

    No A/C here, and no laptop cooler, with the back cover on.

    To be honest i can't find any reason that you should improve cooling performance in 1600$ + machines. Just return them and buy something better for ur money. Huge gaps and not matching vents for such money are not worth IMO.

    P.S. Pls dont flame me, i just wanted to share my thoughts.

    I'm not taking off the heatsink again. It's exactly as I said. I attached the fan directly to the radiator. On the bottom, other side, I put foil there also. Same as putting foil on top as this thread OP demonstrated.

    I would do these changes to the cooling anyway. Did it to the G73JH 3.5 years ago as soon as I got it. Did that with a previous Asus G1. I'll do it when I upgrade again. It takes about 10 minutes to do if you have everything available. NBR members have been using memory heatsinks, foil, and ICD7 for years now on all brands and models.

    I think you may have got yourself a lemon. As others mentioned, something is going on with your unit. I'd try and see if you can get serviced/replaced.

    I might be late to the party here, but is it acceptable to seal the gap with foam (another poster showed an image of this problem as it was dealt with in the alienware m17x) Does such a "foam strip exist"? I know I have one sitting on top of my gtx 480 in an old desktop around here somewhere. I just have never seen them being sold separately. What would be the name of this product if it did exist?
