So, product put into operation over the WE: - RTX 4090 is shown as 16GB in the product pages for the black and metal model -> In the system it is shown as 16GB by the Corsair Dashboard, in HWInfo and Nvidia as 24GB. - i9-14900K undervolted due to the current hardware problem in the BIOS (CPU Lite Load Mode 4) -> runs stable until a possible BIOS update - Idle: Water temperature, both for CPU and GPU, at 35C -> at the upper end of the recommended scale (30-35C) - Lite load (CPU load approx. up to 20%): Water temperature increases to 40-42C -> at the upper end of the recommended scale for FULL-Load (40-45)! - Full-Load: Stress test with the Corsair Diagnostic Software for CPU and GPU increase the water temperature to 50C+, the 10-minute Cinebench benchmark must be cancelled after a maximum of 2 minutes, as both the CPU throttles thermally (see current Intel CPU situation), and the water temperatures already reach 55C -> according to AIO manufacturers, there is an acute risk of damaging the system above 60C. Unfortunately, it is not possible to change fan curves either via BIOS or software. This means that the PC cannot currently be used at high work or gaming loads without ending up as a warranty case in the foreseeable future due to overheating of the CPU or a defect in the water cooling system. Question: Individual case (i.e. request replacement), or general problem with this product (return)?
