I recently water cooled my XFX 6950 2gb reference cards. The specific model I am testing is (XFX HD-695A-CNFC AMD Radeon HD 6950 2G). I put on some XSPC water blocks, as with air and unlocked bios, they were hitting 95C + on load, which was worrying me.
hardware / test setup :
CPU : i5 2500k (also water cooled with an HK Supreme HF)
Motherboard : Asus P8P67 PRO
Case : Corsair 600T
PSU : Corsair HX1000
Memory : 4x4GB G.Skill DDR3 1600
GPU : 2x Reference 2GB XFX 6950’s shader unlocked and oc’d
Hdd : OCZ Solid 2 120GB
You can view the rest of the rig here :
The load temp will be running OCCT v3.1.0 for about 15 minutes.

If you want me to test some games, let me know. I can always switch the BIOS back to stock as well.
