i7 8700k 4.7MHZ plus Kraken X72 performance
I'm experiencing 70 degrees during stress tests, ranging from 65 to 70 when playing BFV. I thought the temperatures should be lower than 60°C while gaming, but are these values typical? How quickly should I adjust my fans and pump settings? Usually they run at 60% and the pump at 2400 RPM.
PS: My motherboard is the Maximus X Hero.
Usually, pumps perform best when operating at 100% capacity at all times for optimal cooling efficiency. Fans can adjust their speed depending on temperature conditions. Your temperatures remain well within acceptable limits, never exceeding 80°C on any single core or overall package temperature—though you might achieve slightly lower readings if the pump operates correctly. In short, running the pump at full speed consistently is simpler than trying to accelerate from a low speed through heavy resistance. Similar to any fan or vehicle, maintaining a steady speed is far more efficient than constantly increasing it from a slower state.
Pump must operate at 100% continuously. Ensure the header connected to the pump, whether via SATA or USB, is set to 100% through the cooling software. Fan settings are mostly up to personal preference, but typically match an air cooler’s curve—around 30-35% speed idle and full speed near 65°C according to CPU thermal diode data. Verify that any case fans linked to the CPU header or pump respond to the BIOS thermal conditions, as most boards now support selecting which thermal diode to monitor for those connections, including GPU temps. Additionally, clarify the configuration of intake or exhaust fans on the radiator and the location of the radiator itself. Inquire about other installed case fans and their respective settings, whether intake or exhaust.

Ensure the pump operates at full capacity constantly. Adjust the header connected to the pump, or if it uses SATA or USB, set it via the cooler control software to 100%. The fan settings are mostly similar to standard air coolers—around 30-35% speed when idle and 100% at about 65°C according to the CPU thermal diode. If other fans are connected to the case but not the pump or CPU header, verify they’re linked to the BIOS thermal condition settings, including GPU temps. Also, check the configuration of intake or exhaust fans on the radiator and their mounting location. Regarding the 3 120mm radiator fans: front intake and rear exhaust aren’t running at full speed because I believe it reduces lifespan. At 65°C during gaming at 4500MHz with AVX offset at 2, should I turn them off? Are those temperatures typical for a 4.5GHz processor?
Usually, most pumps perform best when operating at 100% capacity for optimal cooling efficiency. Fans can adjust their speed depending on air currents. Your temperatures remain well within acceptable limits, never exceeding 80°C on any single core or on the unit’s overall temperature. With proper pump operation, you can likely reduce these values slightly.
In short, pumps are much more efficient when running at full power consistently rather than trying to accelerate from a low speed against heavy resistance. Just like any fan or vehicle, maintaining a steady speed is easier for the engine than constantly increasing speed from a slow start.
Many pump motors aren’t built to handle PWM signals or variable voltages; they’re typically designed for continuous full-speed operation. That said, it’s not mandatory to run at maximum speed all the time. You can choose a pump speed that matches your cooling needs—just avoid dropping below about 25% of the maximum speed unless you’re certain the pump will reach full capacity quickly from lower speeds.
If your temperatures stay within specifications during the highest loads, consider setting the pump to 90% or slightly higher. This keeps performance stable without forcing the pump to repeatedly increase speed when loads change. It’s wise to check whether your pump was meant for variable or fixed-speed operation before making adjustments.
