The block arrived today and I can confirm that it fits the card ?
Thanks again for the fast support!
I'm very happy with it (will need to wait for my 90° fittings to arrive to able to put the glass back on my case
).
Initially the temperatures jumped to 80° under load but after checking a re-applying the block all is fine (I think the block wasn't push hard enough on the GPU die).
As for temperatures, here's a small comparisson:
After 1 hour of Furmark GPU stress test @2650*1440 with an overclock of
+165 on the Core clock and
+850 on the Memory
Stock cooler (fans fixed at 100%)
Idle temp: 38° (fans 30%)
Max temp: 81°
Max clock: 1980 MHz
EK VGA Supremacy block (slightly modded as the mounting holes were a bit too large)
Idle temp: 34°
Max temp: 68°
Max clock: 2030 MHz
Alphacool NexXxos GPX
Idle temp: 32°
Max temp: 59°
Max clock: 2085MHz
