Hi Guys, I am new to the forum and wasnt sure what first post to make, so I figured out it may as well be this one... I have been taking my cooling to its final step this weekend so thought it may be of interest for folks to have a bit of a reference topic as to how a few things work out. The system: Case: Corsair Obsidian 800D Mobo: Asus Maximus Extreme IV - Z CPU: Intel Core i7-2600K @ 4.8ghz GPU: 3 x Sapphire Radeon 7970's running standard clocks (for now) RAM: 16GB of Corsair Vengeance 1866MHz HDD: 2x OCZ Vertex 3 Sata 6 SSD PSU: XFX Pro 1250w Black gamer Edition Cooling & Monitoring CPU Block: EK Supreme HF Plexi EN Radiator: 1 x EK Coolstream XT 360mm Copper Fins - Single Circuit Reservoir: XSPC Acrylic Dual 5.25 with pump inside Pumps: Alphacool VPP655 - D5 Pump Rad Fans: 3 x Scythe Gentle Typhoon 1850RPM - AP15s. Case Fans: 3x Corsair 140mm fans. Coolant: Feser Aqua - Ultra Pure Water Ok, So what I propose to do is as follows: Run the NEW Aida64's system stability test for 10mins as it is now and got a screenshot. Install my new radiator and fans and repeated the test and got another screenshot to see what the extra cooling area does for the CPU (if anything). Installed my EK waterblocks on the 7970's and again, repeated the exact same 10min test. Run the same test again, but with no fans. (Passive) The radiator being added is a Phobya Extreme Supernova 1260. The 4 x 200mm fans being installed on it are the Cooler Master MegaFlow 200 If anyone has any usefull comments or suggestions I would love to hear them.
