Temperatures exceed 90 Celsius during FPU toggling in AIDA 64
Temperatures exceed 90 Celsius during FPU toggling in AIDA 64
I recently assembled my first PC using the NCase M1, after much investigation I found that the H100i v2 would not only fit but also support overclocking with the i7 7700K. Many people reported reaching speeds up to 5GHz. However, when I tried to push the CPU to 4.8GHz using 1.315V, the temperatures stayed around 75-80°C on the CPU. Switching the FPU caused even higher temps—95°C or more—and it would throttle, so I stopped using it right away. Is this typical? Could it be related to the H100i? I was considering changing the thermal paste because it’s causing these high temperatures. The idle temps are about 37-41°C, and my room is around 27°C.
the issue is... the silicon lottery
not all 7700K units are the same. Some will achieve higher clocks with lower voltage, while others won’t perform well during stress tests. Are you running the H100i v2 pump and fans at maximum speed?
if you applied the standard pre-installed thermal paste with the cooler, it’s of reasonable quality. My last three coolers were Corsair AIOs, and I’ve never faced TIM problems.
also, what is your airflow/fan configuration, and are you using the H100i v2 as an intake or exhaust?
I haven't been able to install corsair link because my motherboard doesn't have a usb 2.0 header, so it's running with default fan speeds. It's currently set up as an intake, providing fresh outdoor air. At first I used push-pull mode, then switched to exhaust, but the tubes were blocking the radiator and not getting enough airflow. Now it's set to intake and the temperatures are improving.

I haven't been able to install the corsair link because my motherboard doesn't have a usb 2.0 header. It's using the default fan speeds and I've set it up as an intake, which brings in fresh air from outside. At first I used push-pull mode, then switched to exhaust, but the tubes were blocking the radiator and not getting enough airflow. Now it's set to intake and the temperatures are a bit better. Hmmm... that's unfortunate, since it means I can't control the pump at all.
I've successfully obtained the correct adapter. When the pump reaches its maximum speed and RPM is at 660, the CPU stays idle at about 30-35 degrees. During the full stress test with all components operating at peak, temperatures rise to around 70 degrees.
