From this list of coolers, which would you recommend for the 5500?  And how would I know if they have compatible mounting holes?

I used a pair of Enzotech CNB-S1L forged copper heatsinks:

The heatsink and video card's mounting hole line up perfectly.  I didn't use the push-pins that come with the heatsinks, instead I used nylon screws for a more secure fit.  I also attached a pair of 40x40x10 mm 5V fans on top of the heatsinks.  You can see my card here:

Did u use arctic silver 5 too ?
is the cooling efficient ?

Re: m14radu

I used OCZ Freeze thermal paste.  The cooling is very efficient.  I currently overclock my V5 to 180 MHz with absolutely no issues or visual artifacts.
