I have a low-profile Asus Radeon HD 6450 (Newegg item# N82E16814121439) with a passive heatsink in my HTPC, though the computer doesn't have enough airflow near the card so it got really hot (100C) until I hot glued a small fan to the chassis to give it some airflow, now it doesn't seem to go above 55C. Though the fan is old and is starting to make quite a bit of noise, so I need something a little more permanent.
So I want to buy an aftermarket cooler for it, though all the aftermarket coolers seem to use 55mm or 80mm diagonal spacing. Though oddly, I took some measurements on the Asus card and the spacing seems to be about 62-63mm diagonally and 55mm across (There are four holes in a square around the chip). Here's a crappy picture. I've looked pretty hard and the only cooler that has 63mm spacing is the Enzotech SLF-40, which is a chipset cooler that goes for $35 on eBay.ca, which is a little more than I want to spend considering I paid about $50 for the card.
Are there any other coolers that would fit this card?
