In order to gauge the CPU performance improvements of Intel's Core i7 mobile technology, we compared Asus’ G51J to MSI’s similarly-priced, Core 2 Quad-based GT725-212US. To gauge the limits of Core i7 mobile technology, we also compared Eurocom’s ultra-expensive, desktop CPU-based D900F Panther.

Encouraged by performance parity in our Benchmarking/OS Comparison and discouraged that Asus’ drivers will only execute under the latest Windows version, we compared all systems with as-delivered software.

Was it only that long ago? It feels like forever.
WRONG!!!
That circular 'vent' does not go through. It is not used for cooling, it is only aesthetic.
The intake vents are those slits around the RAM , the 2 hard drives bays and around the video card. Thus leg position is NOT important. The cooling system is very good.
That said, the Asus G51 series is by far the most common gaming oriented laptop as its performance is stellar for the price
A better cooled system would be the Alienware M15x or the Clevo W860CU (both also 15"). Clevo also offers a comparable 17", the W870CU
Good cooling means that each heat producing thing has its own fan and set of fins/heatpipes (which takes a larger notebook)
Microcenter i7 920 = $200
250GB 7200 RPM = $65
Total = $2024
So, then does this notebook have good cooling for it's size? It is having to dissipate quite a bit of power when both the CPU (45 watts TDP) and GPU (75 watts) have their pipelines full. Yes it can run hot internally, but the underside of the case stays out of roasting-balls and/or pubic hair range because the motherboard is screwed into the laptop from the underside of the keyboard instead being attached to the bottom of the case.
I do agree that a second fan would be an awesome improvement, or have the one replaced with one that can move more air.
I would venture that few laptops can dissipate that much heat as well as this one of this size. One that may have better cooling would be the HP envy 15, and some of the exotic laptops.. imo
This slider I suspect is NOT spring loaded but the left slider IS.
I have the G50VT (predecessor), and this is the case with mine and often the battery has been dislodged in my computer case as I walk from class to class, cutting power to the RAM when in sleep mode.. I ended up taping my battery in with scotch tape! Worked like a charm.

I venture the guess that this issue has not been fixed.
My HP laptop is built the same way, and it hasn't caused any major problems... just be careful how you carry it!
That said, those latches do look pretty weak, so you do have a point.
Scotch-taping the battery down the way you did is also overkill - taping the latches into their locked positions would have sufficed.
1.) The "Fake" intake is the real main intake. If it's blocked, there's enough space between the fan and the hole to draw air from other places such as the slits over the RAM.
2.) The bottom doesn't get hot, but you can almost roast vienna sausages from the side outlet.
3.) In the photo, the battery is unclipped on one side. It is a design feature to make battery removal easier. It did not affect testing.
the real thing is desktops are still better for gaming...who agrees with the article and me there?
I will back up this post as well. I have an Asus laptop with the same cooler design. If you actually take it apart, you're realize that the giant circular 'intake' at the bottom doesn't actually go through anything. I'll admit, it's a little misleading when your laptop has a giant circular grill looking thing at the bottom lined with mesh and it ends up pretty much doing nothing.
Nvidia GeForce GTX 260M 1.0GB
Six-cell 11.1V 4800mAh
15.6" LED Backlit 1080p (1920x1080)
For $1500, you might as well spend the $100 for the MSI model. However, MSI, ASUS, and Eurocom represent some of the best companies in laptops. Its league all its own.
The Asus would be 1920x1080.
The Eurocom would be 1900x1200.
The MSI would be 1680x1050.
