I'm building a PC for my girlfriend and everything went smoothly except for the liquid cooler installation. After benchmarking with Prime95 and even playing some mid-range games, my CPU temperature hits 95°C really quickly and stays at that level during stress tests. I've double-checked that everything is correctly plugged in, and in the BIOS, the CPU_OPT fan shows it's running. I replaced the thermal paste today, but the temperature issue persists. I suspect that the cooler might not be making good contact with the CPU because I had a tough time with the buckles during installation. Could I be overlooking something? Here's what I'm working with: MSI Coreliquid 1369 AIO Liquid Cooler, AORUS B550 ELITE AX V2 motherboard, and an AMD Ryzen 7 5700G processor. Also, the CPU_OPT is showing a speed of around 2410 RPM in the BIOS, so at least the pump is operational.

Did you remember to remove the protective film from the CPU block? Sometimes people forget that part. Just a quick check could save you a lot of hassle!
Make sure the radiator is positioned above the CPU so gravity can help the coolant flow down onto the CPU block. Also, double-check that all fans and the pump are correctly connected. Just because the CPU_OPT speed is running doesn't mean the pump is working properly; it might just be a fan that's spinning.
The radiator is above the CPU, and I've connected both cables to their respective ports. The fans seem to be working well, but I'm starting to think maybe the cooler isn't mounted properly. I had a tough time with the installation and didn't use the AMD standoffs because the backplate was loose. That might explain the temperature issues.
Yeah, I totally get that! I checked it and there was nothing left on the CPU itself after I removed the film from the cooler.
