reccomended hsf for mobile a64

does any1 run a mobile athlon 64 in a desktop pc? can any1 reccomend a hsf that doesn't need "cutting up" to work as the chip doesn't have the heatspreader/shield/whatever u want to call it! stuck on top :crazy: please help, thanx rich

p.s. i've tried an arctic cooling ultra 64 tc. it didn't touch cpu even with an extra thick blob of paste. i soldered off the 4 plastic pins in the corners but the lever now goes "past the point of no return" & the hsf is unstable & tends to either fall off or slip!
