My gpu temps with the Heatkiller block...
Ambient temps 27C.
Furmark 15 minute 1920x1050 Burn in Benchmark.
The VRM temps are still hotter than I was hoping for but the card is over clocked like a beast and over all the VRM temps are decent for this over clock with water.
This water block looks great and performs great.
Sidewinder computers has the best deal on it.
