HatTrick Posted January 26, 2016 Share Posted January 26, 2016 Hi all, First post on these forums. I'm in the planning stage of upgrading my main overclocking and gaming rig and I'm trying to decide which one of the 750d and 900d would fit my needs best. The main goal is to maximize cooling performance while at the same time keeping it as quiet as possible. My current system is: Intel DX79SI with i7-3970X at 4.4GHz cooled by a thick AIO 120mm cooler from another brand with two fans in push-pull config. Corsair Vengeance 1600C8 DDR3 4x4GB ASUS GTX680 DirectCUII 2x Intel 730 SSD 1x Samsung 840 EVO SSD It will in the near future be upgraded with the following: Another ASUS GTX680 DirectCUII that I just got cheap 2nd hand but it doesn't fit in my current case. ASUS Rampage V Extreme with an i7-5960X or 6950X Corsair Vengeance 4x4GB DDR4 Custom watercooling system. Initially I'm looking at cooling only the CPU with water. The radiator I have in mind is the Alphacool NexXxos UT60 280 or 420(maybe overkill?) with Noctua NF-A14 PWM fans in push-pull and a Swiftech Apogee XL waterblock. I know the 900d can fit either of these two 60mm thick radiators with 25mm fans on each side of it in the top of the case. But does the 750d have the same 110mm clearance between the motherboard and top of the fan mounts as the 900d so a UT60 280 could fit or would I have to use a thinner 45mm radiator with that case? In the future I would like to have the option to watercool one or two new video cards as well as the mobo. Would the 240/280 space in the front and 140 in the back of the 750d be enough for rads to cool let's say two GTX980Ti and the RVE mobo? Any other comments about watercooling an overclocked 8 or 10-core i7? Link to comment Share on other sites More sharing options...
