CDEvans Posted September 2, 2018 Share Posted September 2, 2018 Hi all. Just installed a new H115i Pro onto my 4790K and it's worse than the intel stock air cooler. @ Idle 42. 34\45\33\32 (Package 42) With a water temp of 30. @ load 100. Running a CPU stress test jumps the CPU temp to 100 within 3-4 seconds. Water temp will slowly make it's way up. I've reseated\pasted the block a number of times with new paste each time so it's not a contact issue as each time shows the same results. Rad is front mounted with intake fans. Corsair ML140 3x Corsair ML140 top mounted intakes 1x rear Corsair ML140 as extraction. Pump is set to performance in that awful software (Link) Fans are controlled by the Commander Pro (Except the two rad ones) Any ideas? Link to comment Share on other sites More sharing options...
CDEvans Posted September 2, 2018 Author Share Posted September 2, 2018 Put my old AIO back on and temps went back to normal. Will return the new one. Link to comment Share on other sites More sharing options...
c-attack Posted September 2, 2018 Share Posted September 2, 2018 Kind of a small time window for anyone to help. Despite your efforts, it is very probable you did not have the cold plate and CPU in good contact. The instant 100C jump is a dead give away for that, particularly if the old cooler can take your BIOS settings, voltage, etc. If the cooler was defective in some way, it would show through the coolant temp and that would take more than 3-4 seconds to be revealed. Hard to explain the bracket installation pitfalls without physically being able to see what you have done, but if you are still interested in trying, that would be the place to start.
