I was playing that hack infested game BF3 for 2 hours and my My G750 is getting hot!!!.
Any suggestions on what I can do to to keep it kool?

I've always wanted to try this: http://www.pugetsystems.com/submerged.php

But, it probably isn't good for the screen, keyboard, etc. :)

Lifting it up and away from the surfaces reflecting heat back into the laptop helps a lot. Moving it away from a heat reflective / containing area - like up against a corner on a desk helps the most.

I move mine so it is sucking air from a space that it doesn't share with the exhaust. Putting the laptop vents over the edge of a surface and lifting it up and away from the surface it is resting on helps.

Under extreme circumstances, like when I am forced to use a Macbook Pro for work, and I have lots of stuff running and the darned thing is making like a hot coal, I actually place it on 4 paper dixie cups - I wish I had a picture to share. It looks silly, but it cools right off.

Last time I couldn't find Dixie cups I used a large Godiva Hot Chocolate cup and it worked surprisingly well. I balanced the Macbook Pro's center over the cup, with the edges hanging off - where the heat collects - and it also cooled right off - the little fan in the Macbook got a lot quieter.

A Macbook Pro's cooling is designed for light usage. When someone does heavy work it gets hot really quickly, like in minutes, and holds in the heat. The little feet don't lift it off the surface it is sitting on causing the heat to collect between it and the surface. So you need Dixie cups :)

The G750's cool themselves very well. The G750JH is amazing at this. And, the JW/JX do great job as well. I don't think you need to worry about the G750 overheating unless you push it up against a corner of a desk against a wall and/or put it in a small closed space - like where people cook their Xbox 360's :)

I do like something like this, but I don't think it is strictly necessary unless the surroundings force it, but it does look cool - and solid enough to hold a G750:

If you do try the Dixie cup method, be sure and double or triple up on the cups for each corner - stack 2 or 3 on top of each other, the G750's have mass in their favor.

do you know what is temp for your laptop when you play game?

Went and bought a Master Cooler 17" cooler for my laptop so far it has not got over 65c.

This Cooler Master model? Or?

What is 65C? CPU or GPU? What was the before / after, gaming with/without the cooler?

A couple of things to note about the G750. The cool air is drawn in from the top of the keyboard area below the screen, it doesn't draw cool air from the bottom. But it does expel it out the back, and putting the laptop on an angle with cool air coming up the bottom will enhance the cooling of the exhaust air.

Cooling the bottom helps dissipate the heat internally even if the cool air isn't drawn in directly.

I have found trying to type on one of these stands is a bit awkward when I am without my wireless keyboard/trackpad. They also aren't very portable - they are larger even than the G750 so they aren't easy to put in a backpack to use when I travel.

As long as you can remove the laptop from the heat reflected by setting it directly on a surface, that is enough to assist in the cooling - active cooling isn't necessary.

The G750 can generate a lot of heat and dissipate it well. I have run 24/7 simultaneous 100% CPU and 100% tasks and watched with the below monitoring tools, among others, and recorded the logs and never saw a throttled processor / GPU due to heat.

I use these tools to view the temps / speeds / rpms:

My G750JH-T4050H Gets allso quite hot for my oppinion or am I just oldfachioned with computer temperatures. I have been told that when a proseccor or memory gets over 70C it starts to damage and its lifetime is going to be shorter. My GPU gets temperatures over 78C When gaming.
Is there a Fan control software to use? I have tried lots and lots of ASUS AI And Fan Programs and none of them have worked on this computer. Do I hve to buy one of those cooling pads?

As long as you don't defeat any of the temperature protections, the laptop will throttle performance when overheated - I have run for days at 100% CPU / 100% GPU at highest stable OC on the JW/JX/JHA, and no overtemp protections have kicked in. :)

100C junction temp for the CPU, the laptop will throttle before that is reached.

I couldn't find a specific GTX7xxm spec, but a similar Kepler chipset from Nvidia has these specs
GPU temp 96C at MAX TDP, shutdown temp 101C

When I ran the JW/JX I would under-volt the CPU to decrease the heat generated, it made a big difference. I used Intel XTU, giving a negative offset of up to -100mV for the CPU/CPU_cache. Even -25mV makes a noticeable difference - some CPU's can handle more reduction in voltage that others - I had one do -100mV, one do -60mV, and my current G750JH -25mV - but the beefed up cooling with the JH makes the CPU temps stay under 80C even under 100% load. Very nice.

Without the undervolt on JW/JX I also had CPU temps in the mid to low 90C, but with undervolting temps were in the mid 80C's.

Here is a saved Profile that doesn't overclock, it just undervolts by -50mV. You load it from XTU profiles, Show, and Apply.
