The cheapo chipset fan on my Assus V7700 Geforce 2Gts crapped out, so I picked up 2. The other will go on my visiontek G3 ti200. Picked'em up for less then $10 ea. at SVC. Anyone using these? Able to OC any higher then stock? They are QUITE a bit bigger and heqavier then the stock cheapos. Any trouble using the push in mounts? Thanx!
