Need assistance with outdated equipment?
Hello, I signed up because I'm facing an issue I don't fully understand how to resolve. My previous PC failed, so I upgraded with some new hardware and salvaged parts from my old machine. Unfortunately, the new computer shows unusual temperature fluctuations that I can't identify clearly. I bought a secondhand CPU (i7-4790k) and a new water cooler (MSI MAG CoreLiquid 240R), while the rest of the components were from what I already owned. My previous CPU was an i7-4790.
I'm currently using Windows 10 Home 64-bit, with the following specs:
CPU: Intel Core i7 4790K @ 4.00GHz (58 °C)
Technology: Haswell 22nm
RAM: 16,0GB Single-Channel DDR3 @ 932MHz
Motherboard: ASUSTeK COMPUTER INC. Z87-A (Socket 1150) @ 28 °C
Graphics: G276HL (1920x1080@60Hz)
Memory Card: 4095MB NVIDIA GeForce GTX 960 (ASUStek Computer Inc) @ 36 °C
Storage: 931GB Crucial CT1000MX500SSD1 (SATA)
Western Digital WDC WD10EZEX-21M2NA0 (SATA) @ 28 °C
Crucial CT250BX100SSD1 @ 232GB (SATA) @ 23 °C
Optical Drives: Alcohol V-SATA CD/DVD
Audio: NVIDIA High Definition Audio
The issue is that the CPU occasionally spikes in temperature during normal tasks like opening multiple browsers. I'm trying to keep it stable and cool, so I'm considering undervolting or accepting a performance drop.
I've attached some photos of my BIOS for reference:

these coolers are recognized for their tendency to fail pumps.
i've encountered more than ten discussions here on this topic, all pointing to the same problem.
the spikes could result from intermittent failures or simply a blockage in the liquid flow.
if it's a new unit, i recommend returning it and opting for an AIO that excludes the pump inside the radiator, or consider using a high-quality air tower cooler.
the water pump should be configured differently than a regular fan in the bios fan profile.
waterpump operates best in a 5000-8000rpm range, and even lower speeds like 1500rpm can cause very slow water flow.
i’m unsure where your pump is connected (which fan header it uses), but it needs to be switched from automatic mode to full speed.
radiator fans can stay in automatic mode as long as it’s acceptable to your ears.
the water pump requires a different setup compared to the regular fan in the BIOS fan profile. it usually operates between 5000-8000rpm, and even lower speeds like 1500rpm can slow down water flow significantly. i’m unsure about the exact connection point for your pump (which fan header), but it needs to be switched from automatic mode to full speed. radiator fans can stay in automatic mode as long as you’re comfortable with the noise.
I attempted to adjust the fan headers, but even at full speed the RPM never exceeded 1900rpm—it’s strange since I don’t recall the PC getting that hot during installation. It’s confusing to figure out if the issue lies with the liquid cooler or my BIOS. I’m considering returning the product for repair, worried the cooler might be fine and I’m just unsure.
fan speed can reach up to 2000rpm
pump speed is 4200rpm ±10%
requires 0.3 amps for maximum performance
current fan headers support only 1 amp
consider setting all fans to full turbo (100%) – one may increase to 4k rpm
I tried an old air cooler with a big heatsink that spins up to 2500rpm, but it only cools the system to 70º, not the high temps it handled before. It seems either my motherboard isn’t compatible or the cooler itself is bad. I’ve had it for about a year and am unsure if I should return it for repair.
i've noticed owners mentioning msi's dedicated page for the mag coreliquid failing pump problem because it's quite frequent. there should be a way to enter your details and check if you're eligible for upgrades or replacements, or if you need to file an actual rma. reach out to their tech support for guidance.
