Hi,
I've owned an MSI Vector 16 HX AI - Ultra 9 275HX/64GB(5600)/2x2TB/RTX5070TI laptop for almost three months. This is my first MSI laptop, and honestly, I've had major performance issues with it. I managed to work around this a bit, so I'll share it in case it's useful to someone.
We use our laptops differently, and this can affect our results. My laptop spends 95% of its time on the desk with an external 4K (UHD) monitor connected, in Extreme Performance mode, and GPU Hybrid Mode. The laptop also sits on an IETS GT600 v2 cooling pad (IDLE OFF, heavy workloads like rendering 400 RPM, gaming 600 RPM). I run these tests with this configuration.
How can we reduce fan noise and improve laptop temperatures?
The problem is primarily the CPU temperature and FAN1 fan speed. If your CPU is running at 90-95 degrees Celsius under stress, this is normal for a laptop. If fan noise doesn't bother you, you don't need to follow these tips.
1. [Most effective] Replacing the thermal paste in the laptop cooling system
This always gives the best results, as manufacturers typically use poor-quality thermal paste or it wears out over time. Examples of thermal pastes you can use: Noctua NT-H2, Thermal Grizzly, Kryonaut SYY 157, Thermalright TFX, Honeywell Ptm 7950. We're talking about a new laptop here, so I'm omitting the need to clean the cooler. I didn't replace the thermal paste in my tests.
Cons: You need to know how to remove the cooler; depending on your region, disassembly may void your laptop's warranty. If you have a new laptop and the CPU temperatures reach 80 degrees Celsius in idle mode, it's best to send the laptop to the manufacturer for service.
2. [Very effective] Reduce CPU clock speed (How to do it?)*
Depending on your CPU, the clock speed can reach up to 5.5 GHz, is that really what we need? We'll have to decide for ourselves. My processor clocks at 5.0 GHz for the two P-Cores and 4.6 GHz for the remaining cores, while all E-Cores are set to 3.4 GHz.
Cons: We do not turn off Turbo completely because this will drastically reduce performance.
3. [Moderate effectiveness] Reduce CPU TDP (How to do it?)*
To put it simply, the CPU operates in Turbo mode (PL1 and PL2). Our CPU in Extreme Performance mode operates at 140W (PL1) and 170W (PL2). This is useful for work where we primarily utilize the CPU. However, in games, our CPU is limited mainly to 65W/65W because the power limit for the MSI Vector is 215W or 240W depending on the GPU (5070TI 140W + 65W CPU). Mine runs constantly at 55W/90W settings. In practice, it's difficult to utilize its full power; Balanced mode is 80W/80W.
4. [Moderate Effectiveness] UV CPU (How to do it?)*
Undervolting the CPU is safe but can lead to system instability. Simply lowering the CPU's operating voltage will reduce power consumption and keep it cooler. I managed to lower the following voltages slightly: P-Core (-50mV), E-Core (-40mV), Cache (-100mV), NPU, SA, and iGPU (-50mV). It's important to remember that 90% of undervolting's effectiveness is achieved by lowering the voltage in the first two metrics (Core).
Cons: Sometimes, if your CPU is not reaching its maximum clock speed due to temperatures, or is unable to maintain it, undervolting will improve CPU performance without affecting temperatures.
5. [Fan Volume] MSI Center Settings
Unfortunately, MSI didn't provide the option to set the fans to modes other than Extreme Performance, and you have to switch to that mode as well. Fan noise in IDLE is usually caused by two fans running. In idle mode, you can disable the second fan (GPU). My CPU fan runs 99% of the time in IDLE at 1800 RPM, and it's silent.
Cons: Without lowering the TDP, we have high power consumption, and Nvidia Whisper doesn't work.
6. [Moderate effectiveness] GPU UV
The CPU and GPU have combined cooling in laptops, so when the GPU temperature is high, the CPU temperature also increases, and vice versa. The new 50xx series cards are well-optimized for energy efficiency. My RTX 5070TI runs at 975mV; I could even lower the voltage to 775mV. We use MSI Afterburner for undervolting (there are plenty of tutorials on YouTube). For me, it looks like this:
1. Set the core clock to +450MHz (core clock input).
2. In the curve editing tab, I select the target voltage of 775mV at the bottom, select everything above with Shift, and press Enter. The curve should straighten out.
3. I increased the memory clock to +2000MHz (memory clock input).
4. Of course, we do everything gradually.
I use two modes for older and newer games:
775 mV / Max Core 2340MHz / Memory + 2000MHz
850 mV / Max Core 2800MHz / Memory + 2000MHz
Cons: Be careful when increasing the memory and core clock speeds.
7. [Very effective] Cooling pad
A good cooling pad makes a huge difference, it can reduce temperatures by up to 10 degrees Celsius with low RPM. Simply lifting the laptop from the back, for example, with a simple wooden block, can reduce the temperature by 3-4 degrees Celsius. I only use the pad while gaming and rendering. I run it at a maximum speed of 600 RPM (MAX is 2800 RPM), which is much quieter than the average laptop fan noise. At 600 RPM, the noise level is 49-51 decibels under full load (measured with a phone 15 cm away from the laptop). The trick is to coordinate this with the fan settings from MSI Center so that the laptop doesn't overspeed. My pad is the IETS GT600; I previously had the GT500; I also tested the Illano and Klim.
Cons: Cost of ownership, noisy at higher speeds.
How do I unlock additional options in the BIOS?
You can change the TDP, UV, and CPU clock speed using free programs like ThrottleStop and Intel XTU. I won't describe how they work because there are tons of tuts online; I'll show you how to do it in the BIOS. It's best to gradually lower the voltage by 5-10 mV. We check CPU stability with stress tests built into these programs or a program like Cinebench. It's also a good idea to test battery life and idle mode.
Before you can use these programs, you must unlock the appropriate functions in the BIOS. To access advanced laptop options, you must use a key combination in the BIOS:
Copilot Btn + FN + Right Shift + Left Alt and click F2
Advanced > Power & Performance > OverClocking Lock set to Disabled
Advanced > OverClocking Performance > OverClocking Feature set to Enabled
Advanced > OverClocking Performance > UnderVolt Protection set to Disabled
For programs like XTU, additionally, if it doesn't work:
In the Advanced tab, disable Intel VT and VT-d. In Windows, disable Core Isolation in Windows Security.
*BIOS Optimization
1. Changing TDP:
Advanced > Power & Performance > CPU PMC > Config TDP Configurations. Set Power Limit 1 and 2; in my case, they are 55,000 and 90,000. You can also reduce the Time Window (how long the PL2 state is maintained); in my case, it is 40 seconds.
2. Changing Turbo Clock:
Advanced > Power & Performance > CPU PMC > View/Configure Turbo Options. You can also set Energy Efficient Turbo to Enabled. In my case, P-core Ratio0 and Ratio1 are set to 50, the remaining P-cores to 46, and all E-cores to 34.
3. Undervolting:
Advanced > OverClocking Performance > Processor. Let's change the voltage setting for individual cores (VF Configuration Scope > Per Core). For each core, the Offset Prefix "-". I also set the Voltage Offset to 50 for all P-Cores and -40 for the E-Core. Additionally, you can change the voltage for the Ring (cache), GT (iGPU), SA, and NPU.
In practice
Of course, this result could be better if someone didn't lower the voltage and could hover around 19.5k. Temperatures while gaming: GPU: 65-72, CPU 68-75 with the cooling pad set to 600 RPM. In IDLE, it's 99% silent (without the pad), with only Fan 1 (CPU) running at 1800 RPM, but it's inaudible. I marked the maximum CPU temperature on the 3Dmark screenshot.
FAQ Extra
This is my first MSI laptop, and I've encountered a few problems:
-When I inserted the second drive and didn't want to use Intel RST, I didn't know where to disable it. You can do this here: Advanced > System Agent (SA) and disable the VDM controller.
-If you're doing a clean install, prepare the drivers for WiFi and Intel RST on a USB flash drive and install them in the installation drive selection window.
-If you're having strange problems with your laptop, reset the EC. Turn off the computer, unplug the power, and hold the power button for 30 seconds. This probably also resets the BIOS.
-The BIOS updates frequently via Windows Update. Remember that all BIOS settings will be reset. Also, disable Bitlocker in Windows.
-Changing the profile to Extreme Performance disables Nvidia Whispering Mode.
