ddr3 vRAM generally doesn't need active cooling. On the contrary, its probably preventing good contact with the core and making the card overheat.
These laptops are built on a similar chassis to the 8710!!!
The heatsink will fit!
The 3670/v5725 is a type II card. It will NOT fit any known heatsink for this laptop! Furthermore, some of these cards do not have an EEPROM or vBIOS - which the x1600 from your laptop might not either, but you don't want a 3670 running like an x1600, do you?
Why don't you just search g84 on ebay, give that a try. Prices are GOOD. I'm in touch with this company.

I heard the 3600m works on this laptop.
Just so you all know, HP cards will NOT help you with MXM upgrades if they are from 2 different HP laptops! Absolutely not. In fact, HP uses more proprietary cards than say, Acer. So, if you're going to try anything, just make it ANYTHING as long as its a standard MXM card with low power consumption.
