My opinion is, go for EVERCOOL TURBO 2 HEATPIPE VGA COOLER

This is how it looks like:








And this is the link to the official website of that VGA Cooler...:

And here's a review for that VGA cooler: 
Evercool Turbo2 Review

There's hardly any cooler that used blow out design other than Artic Cooling ..which recently they ventured into other design... so unless u specify which gc u need to cool off else it's hard to recommend any...
It's always not advisable to use a gaming laptop for serious gaming coz it would just shoot up high in temperature .... very hot most of time

the most effective solution would be staying an aircond room ... it can't be cooled even by any laptop cooler ...

hmm there's no option for rear exhuast blower for ur card anymore or pretty much none for any other mainstream card now days...

these are cooler from AC that could fit ur card: Accelero X2 and Accelero S1.

It would be better to get Accelero S1 for it's optimun performance without generating too much of noise ....

haha...
mine from 58-85 drop to 36-45 now!!
almost 30c!!
thx for the recommendation pal!!!

nothing much on the heatsink itself

just the new Accelero S1 Rev. 2 now comes with a new flexible mounting mechanism

multiple screw hole sets

and modifications to the heatpipes enabling it to fit a wider range of leading graphic cards

VR Zone: Accelero S1 Rev. 2 Fits More Graphics Cards

Every graphic card could work beyond 80c in general ..

however it's not a good practice to maintain such heat level all the time ...

To know specifically at what temperature ur card could work stable ...

use ATI TOOL and loaded up the artifact test ... once it reaches a point where artifact shown .. that's the limit ..

but generally unless u OC card further, usually at default setting very hard to achieve such temperature unless u turn down the fan speed on cooler ..

Posting it tmr...happy new year
