http://forum.techinferno.com/general-notebook-discussions/222-what-do-you-use-cooler-your-notebook-9.html#post50527 I made a custom forced air cooler for use at home....I got tremendously good results with it. I might suggest something like that instead.

I really wanted a good cooler for my GT70 while I was at home. I generally use it mostly at home, but I do take it to work with me every day as well. I wanted something that was simple enough that I didn't have to fiddle with switches all the time, or with plugging it in, and still provided very good air flow. Long story short, there were no good solutions commercially available. Targus, CoolerMaster, and many others, were basically just fans that blew air at the bottom of the laptop. This really doesn't help airflow much, if any to be perfectly honest. So I drew up in Autocad, a simple box. From there, it morphed into what you see below in the pictures. The actual plastic part took the most time, simply because custom fitting everything really is a pain in the butt. The wiring was actually very easy and simple. I added the switch, so that I never have to do ANYTHING to turn this on, just place the laptop there and it turns the fans on. The power supply is a wall wart that can output +12VDC@800 mA, more than enough to run the fans and some LED's eventually. I haven't finished the LED's yet, as they require a bit more time to get all the wiring done properly. Overall, I don't have any temperature information on how much it might help at this point, and I'm not sure I want to dig that deep. I'm very happy with the solution, and once I get the LED's added, I'll be sure to post more pictures. https://lh3.googleusercontent.com/-FS8vDv22zaQ/UZN_sWScD1I/AAAAAAAAHks/cshPgewU79s/w1045-h784-no/IMG_20130515_081749 https://lh5.googleusercontent.com/-qrp9M-ndYyE/UZN_vijFUpI/AAAAAAAAHk0/LbwLreSDvWI/w1045-h784-no/IMG_20130515_081736 https://lh6.googleusercontent.com/-3rOyhr-t9XA/UZN_xl1MvWI/AAAAAAAAHk8/AvCkIztYLAU/w1045-h784-no/IMG_20130515_081724 https://lh3.googleusercontent.com/-MAoyxwbRGgU/UZN_z0YKVeI/AAAAAAAAHlE/HXEGCPDp604/w1045-h784-no/IMG_20130515_081641 https://lh3.googleusercontent.com/-7kNzD4l25gs/UZN_2KQ3J8I/AAAAAAAAHlM/TuV4C5ye3Ro/w1045-h784-no/IMG_20130515_081631 https://lh5.googleusercontent.com/-6fWQ99pl4Hg/UZN_4hkPZ4I/AAAAAAAAHlU/N1Lfy5VYmqo/w1045-h784-no/IMG_20130515_081620 After some initial testing, I was running my laptop at 1GHz GPU Core clock, which previously I topped out at around 941 MHz GPU Core clock and still had a stable notebook while gaming. Surprisingly, even with this extremely high overclock now, the laptop stayed within the 60C +/- 3C range without any issues......I'm really impressed and happy, since these were extra fans I removed from an old Desktop computer a long time ago.

I've got an MSI GT70 that I'm slowly building a completely custom cooler for. I'm maybe 1/4 done so far since I only work on it during my lunch break at work. That being said, I'm using 2 x 120mm fans in the rear, 1 which will force air into the cooler for the GPU and then out the side exhuast, and the other to cool the CPU and memory and everywhere else int he notebook. I'll be making it so I can still access the rear inputs to the notebook, and will most likely be making the top of the cooler completely open with some foam/rubber on top to create a good seal with the bottom of the laptop. This should help prevent air from escaping the enclosure. Overall, it will be interesting, since it will autocenter the laptop properly where it needs to go. I wish I had photo's of it right now, but it's still mostly in pieces and barely recognizable as a cooler. Probably end of April I'll finish it. Will probably post pictures then.

Honestly, I wouldn't worry about it too much. 1.025V is more than enough. If you use MSI Afterburner, you should now be able to overclock the core by more than +135 MHz. I don't really recommend much over +200, as it tends to not be very stable in my experience. +190 MHz is what I usually run on the core, and anywhere from +500 to +800 on the memory.

You really shouldn't be using the VBios from the first post...it's pretty bad..... http://forum.techinferno.com/general-notebook-discussions/1847-nvidia-kepler-vbios-mods-overclocking-editions-modified-clocks-voltage-tweaks.html use that one instead. You don't need custom drivers from laptopvideo2go either...you can use the standard ones from NVidia.

Sorry for the really late reply. Was traveling to Canada and haven't checked the boards in a few days.... It's not really necessary to update the BIOS for the VBIOS before the EC. For MSI, they're not linked in anyway..... What I would caution though, is if you have a notebook that CAME with Windows 8 pre-installed. I'm not 100% certain how the EC will effect that. I know that the newer (Win8) versions of the GT70 do have a slightly different EC and BIOS. Mine came with Windows 7, so the BETA EC worked great, and I haven't had throttling issues EXCEPT when it gets too hot (as one would expect......This happens if I forget to turn the fan on HIGH....I'm old, sue me....). Update the EC. Maybe update the VBIOS afterwards so you can overclock past +135 MHz core, and you should be good to go.

Install the BETA EC for GT70(1762). That should help fix most of your problems.... If not, I suggest taking the notebook apart and replacing the heatsink compound on both your GPU and CPU with some high quality compound. This will help quite a bit. My GT70 doesn't throttle at all, even under full load for long periods of time while OC'd to 980 MHz.

You can overclock an I7-3610QM or 3630QM, provided you have a bios that enables that function. I currently do on my MSI GT70 that allows the changing of BCLK. While you can't change it much (roughly only 2 or 3 MHz), it's enough that if you really NEED that extra little bit, you can. I don't, because suffice it to say, I care more about my video card having a higher overclock than my CPU.

You shouldn't need to unlock the bios to downgrade. You just have to disable UEFI and set it to Legacy mode (if I remember correctly).

Might as well chime in to say that my GT70 maxes out around 1 GHz core/2.3 GHz memory. Any higher and I get driver crashes with the latest drivers. It also runs it at a voltage of 1.01xV under max load.

http://assets.vr-zone.net/15462/gt70_2.jpg That's an image of a GT70. The GT60 will be identical, just slightly smaller. I can't find one of the heatsink removed, but needless to say, modifying this would not be an easy task at all. It would take alot of patience and time, as you would most likely have to either A) Remove EVERYTHING inside the case in order to file down the mounting points, or Very carefully tape off the entire motherboard and case and ensure that any small filings don't get down to the motherboard. Either way, you're taking a huge risk for a potentially little benefit. If you file it too much, you might crack your core on your GPU, yet another risk to add to the mix. I would most likely go ahead and do the thermal re-paste job. That, at the very least should help. The thermal pads I wouldn't worry about for the memory, unless you're going to get some very new-tech pads that have a heat transfer of at least double the norm. Otherwise, it's really not worth it (since the memory overclock is pretty pointless).

When I get around to it, I'll post one of my GT70. I know, it's not exactly the same, but they actually have pretty much the exact same physical layout, just one is 15.x" and the other is 17". What I would keep in mind is that with a 15" notebook, you're losing roughly 2" to the larger GT70. 2" is alot once you start considering the heat dissipation of a heatsink with a fan blowing on it. When you hit your turbo button, and the fan spins up, you should be able to feel a decent amount of air blowing out of the vents on the left side of the notebook. Do you feel that air if you put your hand there? What are your current temps when playing a DX11 game and what game(s) are you talking about? I play quite a few, but most of them barely top the temp charts above 75C even when I run it at 1000 core/2400 memory. Knowing this could help give everyone an idea of how intensive the game is and if you have a cooling problem.

I'd wager that there is still something else wrong with your notebook. 93C is a bit too high yet.....Perhaps your heatsink doesn't have enough contact pressure with the GPU or you don't have sufficient heatsink compound there. Those are the only 2 guesses I have regarding that unfortunately, without being there to look at it.

You wouldn't have a download link for that? I've found a few, but I don't really trust them. Also, after updating to the latest (310.70) NVidia drivers, now I'm at 405 MHz core 162 MHz memory, so that's better, but it really should be lower (even with GPU-Z and MSI Afterburner open). Well, I got 1.9.6.7. Not the newest I don't think, but good enough. Hmm...I guess it really is just MSI Afterburner causing all the problems. That kinda sucks since I enjoyed the graph for monitoring the temperature. Oh well.

Usually I use a second monitor, but right now I have none connected. Strictly just he laptop itself with NOTHING else (no mouse/keyboard/sound, etc...) connected. NVidia Driver: 302.75, what comes installed by default. I suppose one of the first things I could do is update the driver. Going back to the 'old' VBios that I saved didn't fix the issue at all. That makes me feel a little better, but it doesn't change the fact that it's on almost all the time. I guess, stupid question, but could GPU-Z or MSI Afterburner be causing the video card to be enabled, and therefore cause it to use higher GPU speeds, even though all I'm doing is trying to monitor the temperatures?
