Unusual sounds and excessive engine warmth
Unusual sounds and excessive engine warmth
I improved my computer setup from: processor: Ryzen 5 3600 Mobo: MSI X570 Gaming plus cooler: bequiet! Pure Rock Slim RAM: Gskill Trident Royal DDR4-3000 CL16 2 x 8 GB connected to CPU: Ryzen 7 7800X3D Mobo: MSI B650 Tomahawk MAG cooler: Lian Li Galahad II Trinity 360 SL-INF RAM: Gskill Trident Z5 Neo RGB DDR5-6000 CL30 2 x 16 GB (also updated the case: Lian Li O11 vision and the fans: Lian Li SL-inf 120). I kept the graphics card: RX6950XT. Power supply: Corsair RM850e and my storage drives. After setting up the BIOS, launching Windows and adjusting the Lian Li software, I observed a few issues. An unusual fan sound that was already there in the previous system reappeared here despite changing all fans. Upon inspection, it turned out to be the power supply unit fan. It's still covered under warranty, so it's not an immediate concern (just noting this later). Another odd noise (difficult to pinpoint, but coming from near the CPU) indicated poor cooling. This gave me two strong signs: a defective pump or trapped air. I attempted various fixes for the stuck air. Eventually, a friend helped us disconnect the pump and all fans, but the sound persisted. Fortunately, the AIO unit worked properly. The problem remained: temperatures stayed high (50–60°C at idle) and the noise shifted location. This made me think about a faulty pump or air blockage. I tried everything to resolve it. Eventually, we discovered the PSU was contributing to the issue. After changing it, the noise disappeared from the back but remained audible from the front of the case. Swapping the GPU resolved the problem completely. Now we were puzzled. The old GPU had no such sounds, and the noise changed only when running a specific game—otherwise it stayed consistent. As soon as we saved a game, the sound doubled in volume. It started about 10 seconds after booting and stopped immediately upon shutting down. This strongly suggested a coil whine coming from the power supply unit. However, why would it vanish when the GPU was swapped? And why did it sound different from what I expected? Possibly just the coil whine of that particular GPU while it was powered on. It still doesn’t clarify the high idle temps. We repositioned the CPU and AIO, applied Kryonaut Extreme thermal paste. Under full load, temperatures reached 70–75°C—well within safe limits. Still, the idle temps were unusually high. In summary: I’m trying to pinpoint the noise source and decide whether any parts need replacement. The sound is mild, nearly silent when the case is sealed, so it’s not a major issue now. However, I remain cautious about long-term reliability. Audio: Disturbing noise during smooth operation.
Hey there! Your detailed comment makes sense. It seems the noise might be coil whine, which can be tricky to pinpoint. Using an app like Spectroid could assist in locating the source. Generally, businesses usually don’t process returns for coil whine issues.
Regarding the temperature trends, what do your fan curves display? Have you checked the specific temperatures of each core? There might be some unusual readings from the sensors you're using. I’ve experienced CPUs showing inconsistent core temperatures, yet the individual cores remained normal.
The idle temperatures appear a bit elevated compared to what you anticipate around 40°C. When evaluating what constitutes a typical idle temperature for your setup, several factors should be taken into account:
1. Room environment and surrounding heat
2. Positioning of the equipment—especially if it's in a poorly ventilated area
3. Fan configuration inside the case, aiming for positive pressure to maintain consistent airflow
4. Radiator dimensions and fan selection; static pressure fans are often more effective than high-flow models
5. Verify proper contact between CPU heatsinks (IHS) and cooling components, such as checking if the AIO is securely attached. Monitoring temperatures while applying slight pressure can reveal if contact issues are the cause.
Regarding noise, it seems to be more about vibrations rather than typical electrical faults. Dust accumulation or debris on fan blades can disrupt balance and produce unusual sounds. For instance, a small amount of thermal paste residue on a fan caused a strange hum when speed increased. Inspecting fans for dust buildup or misalignment is advisable. If you suspect a GPU fan, disconnect it temporarily to test for anomalies. Ensure no obstruction between the fan housing and the board. Reconnecting after testing can help confirm if the issue lies elsewhere. Long-term effects depend on identifying and resolving the source of the noise. Good luck!
I did the same upgrade yesterday with a new processor and fresh firmware. Since it’s a more powerful chip, I expected higher temperatures, so I made sure each core was heating evenly before feeling confident.
Hello, thank you for your prompt reply. I’ll go through all the concerns. 22°C with 50% humidity is ideal. The rig sits on a compact desk with ample space around it. The case fan configuration matches this setup exactly. (At the time I linked, around 7:30, he mentioned ambient temps near 35°C while using nearly identical arrangement.) The fans are the pre-attached Lian Li SL-INF 120mm units, which help resolve several issues. I repositioned the CPU and AIO multiple times, adjusting the tightening of mounting screws to different strengths. I’ll attach a photo of the thermal paste pattern at the end. Regarding fan noise: although it sounds mechanical, removing every mechanical part still left some sound. You’re likely correct about an electrical failure, but I’m confident the issue is with the GPU. Earlier, I noticed another instance where the noise increased. During some light CAD modeling, the sound intensified when I spun the model and vanished instantly when I stopped moving it.
Hello, thank you for your prompt response. I’ll give it a try. I hope it’s just coil whine, which means I won’t need to return anything since the noise is quiet enough.
I followed the standard fan curve in lian li software, yet increasing the fans didn’t significantly lower temperatures, suggesting a possible mismatch. The load temperatures seem normal, so it’s unlikely the problem lies there. I reviewed the Temps using HWinfo, but I’m unsure if core-specific variations were accounted for.
It might simply be running a bit warmer than expected. If you're covered by warranty, reach out to customer support to check replacement options. When under stress, temperatures shouldn't exceed levels that trigger throttling—so it probably isn't a major issue right now. Regarding the noise, it appears the problem is likely electrical and could result in future failure. You may need to replace the suspected parts. The paste and IHS distribution seem intact, which rules out overheating as the main cause. If the pump failed, temperatures would rise rapidly to 70s or 80°C almost immediately from the BIOS.
